RAUSA:
What about the F7U Cutlass? Wasn't that in the same time period?
SPANGENBERG:
The XF7U was a result of the Navy's first real fighter design competition
after the war. It was to build a day fighter. It was a big competition. The
proposals came in two sizes, powered by Westinghouse J-34 engines or GE J-35s.
Small engines and bigger engines. The small engines weren't quite enough
to do the job. The bigger ones were. The Navy had a reputation at the time
for building only conventional airplanes. Most of industry thought we were
well behind the Air Corps and unwilling to take aerodynamic risks. We had
no tail-less airplanes. In fact a lot of them thought the Navy was still
in the biplane days, and that Walter Diehl our number one aerodynamicist,
would never approve a tailless design, but he did. The Vought design had
by far the best performance of all the proposals. A lot of things we were
worried about, but all the engineers checked off on it. Walter Diehl said
"at least we'll solve the subsonic tail buffet problem."
RAUSA:
The F7U was not supersonic.
SPANGENBERG:
It was not, it was subsonic, somewhere in the .9 Mach bracket, between .9
and one. I thought that the decision to build the original XF7U-1 was a good
one and the airplane was a successful flying machine. Unfortunately the thing
that happened to it was they made it into an all weather fighter by adding
in the first of the Sparrow missile systems and the weight went up by something
like fifty percent. When it did that we ran out of all our design margins.
You should have had a bigger airplane if you're going to try to do that.
RAUSA:
Was the biggest problem the lack of stability?
SPANGENBERG:
Not really. It was a good enough airplane. The Blue Angels flew it for solo
demonstrations.
RAUSA:
Whitey Feightner.
SPANGENBERG:
Whitey actually bent one. Did he ever tell you that story?
RAUSA:
No.
SPANGENBERG:
They were doing an air show and some light airplane wandered across the air
field right in the middle of the show. I don't think they ever did find out
who it was but all of a sudden it appeared right in front of Whitey. He had
to honk it around pretty good and overstressed it.
RAUSA:
The problem with the F7U then was it gained weight and it became more difficult
for the pilots to handle?
SPANGENBERG:
Well, your takeoff speeds went up. You lost your margins on catapulting.
The planned higher thrust Westinghouse J46 engines didn't turn out. Eventually
the original engines didn't show up and we had to fly the early production
airplanes with J35s, one of the early jet engines. It was slightly underpowered
with 35 swept wings and with the tailless configuration, you'd get a horribly
high angle attack in order to get enough lift to come aboard. And then
the increased weight of course it just added to all those problems. We
knew we had a problem in the first place but when it went to the all weather
version, F7U-3, it just got -- we tried to do too much. We in the Navy.
The engineers didn't like it any better than the fleet did. We broke backs
of pilots with the nose gear slamming down. The way it ended up it was
not a successful airplane but I still think that our choice of the XF7U
from the competition was proper.
In more or less that same
time frame, '47, we got the results of all the German swept wing and Delta
wing research. Douglas had a team over there in Germany, came back, gave
us a research proposal for a design that eventually became the F4D. We had
that program going for about a year before it became time to do another fighter
competition. In those days it was called an interceptor. This was a short
legged fighter, high performance. It was supposed to get off the deck, get
up, and intercept incoming bombers. A competition was eventually run with
Douglas entering the F4D which they already had under Navy contract as a
research project. McDonnell entered the design that became the F3H. The official
decision probably says that McDonnell won the competition and we just continued
the F4D program. In fact the F4D Skyray was by far the better airplane. I
didn't think we should have bought the McDonnell airplane myself but we did
and then it was touted as a great idea to have competitive programs going
anyway. "Douglas will keep McDonnell honest and vice versa." That series
of airplanes were all built around the J-40, one of the big powerplant busts
that the Navy had. The Westinghouse J-46 and the bigger J-40 engines. They
really screwed up a bunch of our airplanes.
Douglas had the great
good sense when the J-40 went sour to substitute the J-57 engine for it.
The J-57 had been started by the Air Force as a bomber engine and Pratt had
tuned it enough and developed it with an afterburner so that it became a
very useful fighter engine as well. Incidentally it showed that the Navy
was willing to buy somebody else's development product. Air Force and Navy
were developing their own engines. We had all of the even number engines,
the Air Force had all the odd numbers so a 57 was an Air Force-developed
engine, 58 was a Navy-developed engine. We had no hesitancy to use the Air
Force-developed engine. It was the best engine around. Anyway, in order to
put the 57 into either the F3H or the F4D you had to open up some of the
frames in the fuselage. The engine was a little larger in diameter, an inch or two over the
original J-40 engine. Douglas bit the bullet and put in the J-57.
McDonnell tried to live
with its frames and put in the J-71. The J-71 was not nearly as good an engine
as the J-57. It gave us all kinds of problems.
RAUSA:
The F3H.
SPANGENBERG:
The engine itself gave us problems. One of the early operational squadrons
flew through a rainstorm and two in out of the three airplanes, the engines
seized. The water going through the engine had cooled off the case enough
that the rotor seized. Things like that.
The other thing that happened
to the airplane was the same thing that happened to the F7U. It went from
an interceptor which our Op Requirement people finally decided we couldn't
afford. You could not dedicate deck space to a squadron of high performance
airplanes with short legs. They obviously got to altitude a lot faster but
they didn't get there fast enough to stop an incoming threat that way. And
eventually of course we went to the CAP system where you got the fighters
out far enough that you could really intercept somebody. The requirement
then was basically an escape for both the F4D and the F3H.
And then when you went
to an all purpose fighter again they got into trouble. You lost all your
design margins plus the fact that we had to substitute engines. The F3H in
particular was not a good fleet airplane. The only thing that was good about
it was the guys came back. I still remember Pete Booth telling me it was
solid as a rock in a groove. Couldn't move it. (laughter). It was not my
favorite airplane. The aviators that I worked with later in my career. John
Lacouture and others said "I think you made a horrible mistake with the F3H."
I agree that the Navy made a mistake on two counts. The F4D was the real
pick from the competition, and then the change from interceptor to general
purpose came later. Both the F4D and F3H suffered. Those planes were really
the end of the subsonic era.
And that year we did the
A2J which was the second step towards a nuclear bomber. It had started with
the XAJ as a demonstration project, while the A2J then was supposed to have
enough performance really to do the nuclear attack job. It had turbo props
in lieu of the R-2800s, and dropped the jet engine as a booster. It had good
performance.
RAUSA:
Was that a production airplane?
SPANGENBERG:
No. It never got that far.
TAPE 7 of 16, SIDE
B
SPANGENBERG:
The A2J was really overtaken by the A3D to succeed the AJ. Nobody wanted
to do composite powerplants if you could do single powerplants. There was
great controversy within the Navy's powerplant development organization.
I think I mentioned this once before. Seldon Spangler was an advocate of
turbo props. He didn't think jets would ever make it on a carrier, and tried
his best to steer airplanes in the direction of turbo props. Most airplane
people didn't want to go that way. A.B. Metzger was one who pushed very,
very hard within the Navy for pure jets. Most of us were kind of in the middle.
The pure jets at the time couldn't quite do the job and everybody recognized
a composite way to go was poor choice. All of us recognized I think that
you couldn't get there from here with a turbo prop if the other guy without
carrier constraints was going to be using jets. We would be in trouble.
In fact the historians
probably would like to take a look at that jet versus prop thing with one
of the early Patuxent tests that was done with an F8F versus a P-80. The Air
Force had the P-80 Shooting Star developed and the F8F was our best reciprocating
engine fighter. And it turned out in those tests that a P-80 could never
shoot down an F8F as long as the F8F never made a mistake. But the F8F in
turn could never shoot down a P-80 unless he made a mistake. If he tried
to get into a turning dog fight the F8F would win. But the F8F was solely
at the mercy of the P-80. You couldn't get away from it. It should have taught
a lot of people a lot of lessons. It was good that Patuxent did it, it educated
a lot of the people.
We had a P5Y, started
as a patrol plane, ended up as the R3Y, as a transport. Patrol planes, seaplane
development was obviously winding down. Their great advantage was being able
to land on the water and with water everywhere all over the earth that you
could operate from. But the logistics of handling the seaplane tenders and
whatnot and as the airplanes got bigger that got to be more and more of a
logistics problem. And the airplane technology advanced so you could do it
from land and then it was tough for the seaplanes to continue.
There has been enough
done on the research programs with the D558 programs so I don't think I have
to talk about that.
The F2Y was a strange
program, and not well done. It proves you can't do long-range planning
I think. It started off and ended up too as a seaplane fighter. There
were a lot of research programs going on at the time. One of them was
the development of a seaplane at Convair called the Skate which was a
kind of a combined wing/fuselage arrangement that would also be a reasonably
decent hull. There was a development up at the Naval Aircraft Factory
along the same lines. We call it a "float wing". We ran a kind of a competition
for that, ended up with --I think Curtiss was playing around
with it too. Eventually the contract went to Convair for the Skate but
instead of building the Skate, things changed and they ended up building
a Mach 2.0 supersonic, ski equipped airplane. Airplane development was
better than I expected. They racked the airplane up in an air show demonstration.
The airplane went out of control due to PIO, Pilot Induced Oscillations,
and it crashed. It was the last hurrah for the guys that were trying to
promote seaplane fighters.
RAUSA:
This F2Y. Was that the Sea Dart?
SPANGENBERG:
Yeah.
RAUSA:
Beautiful airplane.
SPANGENBERG:
Oh, yeah. Pretty. We used to have a requirement in our general spec. An airplane
had to look good. It met that criteria.
Next on my list seems
to be the WV, which frankly I scarcely remember. It must have been the first
of the early warning prototypes with radomes on top and bottom of a Lockheed
Constellation. Little in the way of airframe development, but a major step
in electronics.
Next we reach the start
of the Douglas A3D, the Skywarrior, popularly known as the Whale.
RAUSA:
Heinemann seemed pleased with his efforts on the beginnings of that program,
but his account of it was confusing to say the least. I'd like to hear your
version of the events.
SPANGENBERG
: Well, I sure agree with the confusion part. Until I read Ed's book, I had
always thought he had an advantage over the other competitors since I knew
he was on some naval research advisory board, and I assumed he knew more
about the state of development of the atomic bomb than I did, or for that
matter, than others in the competition. Actually, I now believe he was just
smarter than the rest of us.
I had better stick to
my remembrances of that time period. Navy carriers were threatened by the
advocates of airpower alone being all that was necessary in the atomic age.
The Air Force had been made a separate arm, co-equal with the Army and Navy.
The large flush deck carrier in the design stage was under attack and was
later cancelled. The AJ, although initiated as a demonstration project to
show that carriers could operate airplanes large enough to carry the "bomb"
had been put into production, but it was not completely credible as the deterrent
of the future. Higher performance in both speed and range was obviously necessary.
Studies were being done by everyone for both Air Force and Navy. RAND produced
a well publicized bomber study for the Air Force. That study concluded that
very large, very high aspect ratio designs using turbo- prop engines were
the preferred solutions for the Air Force. Similarly, studies done under
Ivan Driggs's direction in the bureau indicated turbo- prop designs in the
100,000 pound class were necessary to meet the requirements then being suggested;
probably at least a 1000 mile radius with a 10,000 pound bomb.
Eventually, the bureau
invited proposals in two competitions, one labeled a "special attack", using
"innovative approaches", and the other for near-term, conventional designs.
The only "Special Attack" proposal I remember was from Convair for a two
stage arrangement with a twin jet, delta wing design launched from a mother
aircraft which carried it from the carrier. I can't remember the details,
but the high performance stage of the design was quite similar to the Air
Force's B-58 delta wing bomber started later. The Navy bought nothing from
the competition, not a surprise.
In the conventional competition,
Douglas, El Segundo alone submitted a twin jet engine design, while both
Lockheed and Douglas, Santa Monica offered four engined jets in the 100,000
pound class. I believe we also had one or more designs using turbo-props.
Heinemann's design was admittedly stretching the state of the art in trying
to meet the stated requirements, and I believe he was really betting that
the 10,000 pound bomb would come down appreciably in weight, and that the
carriers would be larger with higher capacity catapults and arresting gear.
The bureau, of course, was betting on the same things. I seem to remember
a relatively long period of negotiation before we were able to define the
airplane well enough to let the experimental contract in the spring of 1949.
I wonder now in 1998 as I edit these transcripts whether Jerry Miller unearthed
the bureau records on the competition in his research while a Ramsey Fellow
at Air and Space. We were either very lucky or very astute in establishing
the final design requirements at a fixed gross weight of 68,000 pounds, with
a 6000 pound bomb. The J40 engines initially specified had to be replaced
by J57s, actually helping the program.
Overall, the A3D
has to be listed as one of our most successful development programs with
many versions of the design seeing service, including counter-measure, photo,
transport, and tanker. The Air Force bought a couple hundred with J-71 engines.
RAUSA:
Heinemann talked about having competition at the beginning of the A3D's development.
You haven't mentioned it.
SPANGENBERG
: Sorry, I had forgotten that, and I really don't remember the details of
the Curtiss design, but I do remember the episode. We carried Curtiss along
for a few months as competition for Douglas. That action was instigated by
Adm. Pride, then Chief, BuAer, as he said, "To keep a poker up Douglas's
-----." Frankly, I always opposed such actions as cost and time consuming
for both the bureau and the contractors, without any real benefit. However,
the practice has persisted and is now standard policy to have a period in
which to get "Best and Final Offers" from two companies before announcing
a winner. I suppose it sounds good, but I consider it speculative theory,
at best. Wonder how many other design proposals I've missed.
RAUSA:
The Curtiss plane, was it ever built?
SPANGENBERG:
No. We cancelled it after three or four months. The notes only say CWVA so
it probably never got to the point where it had been given a designation.
Then we get into the fifties.
Did you get around to reading that Gold Book article?
RAUSA:
Yes. I went through those. I copied all that stuff.
SPANGENBERG:
It really summarizes most of the story of the tactical airplanes from the
fifties on. I did not cover the other types of aircraft. On this list of
"starts" we have the HSL, the first aircraft in the fifties. It came from
an ASW competition and at the time I guess the biggest powerplant in a helicopter
was probably the R-1820. Bell proposed a tandem helicopter around a R-2800
engine which gave them a substantial increase in power. It was a good engine.
Well liked. We knew enough about the engine. They designed their helicopter
around it. It had much better performance than anything else. Bell was proposing
a tandem helicopter for the first time and everybody had their fingers crossed
on that. Piasecki had been the only one that had built a tandem before. Contract
went to Bell and the program as a whole was not overly successful. They had
flying quality problems with it.
RAUSA:
Do you recall the designation of the tandem?
SPANGENBERG:
HSL. It ended up with primary usage as a mine sweeper rather than going into
the fleet as an ASW model.
The S2F came from a tough
competition. It was the first carrier-based ASW airplane that had a chance
of doing the job. Up to then you couldn't do the job in a single airplane.
You couldn't do it well enough anyway. You remember we had the AF Guardian,
had an S version and a W version. One carried the search radar and the other
carried the weapons. That's a poor way to run a carrier. So it was time.
And as I said it was a good competition. Grumman won the competition because
it had by far the best aerodynamic configuration for getting single engine
performance. You could lose an engine with that one and at proposal time
fly away with ease either on takeoff and obviously much easier on wave-offs.
The ability to do that required lots of span. You remember that we had to
go to an overlapping wing fold which is the thing that really kept the other
designs from being competitive in the competition because they elected to
stick within the folded span requirements but then with a conventional kind
of a wing fold they didn't have enough span to solve the single engine problem.
I thought that the Navy's requirement was pretty good. The airplane was a
good solid design, lasted a long time.
RAUSA:
You're talking the S2F.
SPANGENBERG:
Yeah. We built later versions of it as the first of the early warning airplanes.
RAUSA:
That would be the E-1 Tracker. Successful airplane.
SPANGENBERG:
The Tracker and the CODS. In a long successful series.
Had another helicopter
competition. Got Kaman into the act with the syncro twin rotor trainer. Then
the HRS, the Sikorsky helicopter with the engine mounted in the nose. The
other services built that one too. I had little to do with those competitions,
Otto Lunde handled them.
Next on the list are three
helicopter models, listed as the HRH, HCH, and HR2S. All came essentially
from the same competition with only the HR2S reaching service. The Marines
issued a requirement for a troop/cargo carrier for the amphibious assault
mission with a 300 knot maximum speed and a 50 mile radius. That speed requirement
is one that persisted for years and is presumably now to be met after almost
50 years with the V-22. In 1950, it was considered quite unrealistic by most
of our technical community, need I say, including me. McDonnell, however,
proposed a compound helicopter with two T-56, wing mounted, engines driving
propellers for forward flight. The pressure jet rotor was powered by air
pumped through the rotor and ignited at the tips. The Air Force had the H-16
at Hughes under development in an even larger size, but without the compound
features of wings and propellers. McDonnell had a small tip mounted ramjet
powered helicopter flying. All were interesting projects from an R&D standpoint,
but with little prospect of service use. The HRH design then gave birth to
the HCH, a heavy lift design with the same pressure jet rotor system, but
without the wings and propellers. It had such high fuel consumption that
even its proponents soon gave up any hope of practical service use and the
program was cancelled. The HR2S, on the other hand, powered with two R-2800
engines, was a real success and provided Sikorsky with the experience for
later production of their SkyCrane model and eventually of course the CH-53
series. .
RAUSA:
That pressure system never succeeded?
SPANGENBERG:
Well, it succeeded in driving the rotor.
RAUSA:
But it had no lasting value.
SPANGENBERG:
No.
And the next set of peculiar
things were the tail sitter VTOLs. Up to that point in time the Navy had
supported VTOL development in a pure research type of way. We were the first
ones to fly jet engines, for example. They put vectoring controls on a centrifugal
jet engine, probably a J-33, added a seat above the jet and pilots could maneuver
the contraption. Believe it was done at Ryan. If you had been around in those
days you could go wherever we had that thing, fly it, and you'd get a certificate
you could hang on the wall.
RAUSA:
Was this the one they called Pogo?
SPANGENBERG:
No. This led to Pogo.
We'd been fooling around
with VTOL in a research phase. Everybody wants VTOL. The only problem is
we could never pay the price to get it. It's still almost true today in a
real general sense but you like the advantages that it gave you. By that
time fighter requirements were into at least high subsonic, low supersonic
speeds. The power thrust to weight ratios were over one to meet high speed
requirements. So the general feeling had been that when you got to the point
where there was enough thrust to meet high speed requirements, this was
more than the weight of the airplane and you should be able to get VTOL without
significant penalty. Well, we never quite got there with reciprocating engines,
but with gas turbine power it looked like we could. And the easiest way to
get there was tail sitters because they didn't require a heavy landing gear.
You also didn't need a high lift system. You do it all with the engine. Kelly
Johnson made the remark in some paper that he gave one time, VTOL did all
the grunt work. Tail sitters or wire hangers or something of that nature
would take off and land first and eventually you could get one that would
land that way and then kneel down and crawl away. It was a problem what to
do with one of these vertical things if you wanted to work on it. We decided
it was time to do that. Congress would no longer fund "research programs".
So the services had to develop a requirement that showed some operational
end use. The Navy developed a requirement for "a convoy fighter" which then
would be deployed on merchant convoy ships to Europe. Every merchant ship
would have a couple of these fighters and one of the joys in the competition
was to figure out how do you recover them. There was a lot of relatively
innovative kind of things to do from the pure tail sitter or grab and then
maybe pull them down with a cable or something as they have done now with
helicopters on small ships. Or landing into a huge net that you would fly
up and stay in the vertical mode and go in and with a probe device on the
belly and you'd grab something. There were a lot of those kinds of ideas.
Out of that competition came the tail sitters, XFV and XFY, Lockheed and
Convair. The Convair design was a pure Delta wing with upper and lower vertical
tails so that in a sense it looked almost like four wings. It had small wheels
and struts at the end of the two wing tips and the two tail tips. No means
of getting it into a horizontal position in the operation. It was supposed
to land on a deck. Hopefully, of course, you had enough control to land safely.
RAUSA:
Did these two aircraft have a lot of accidents in the development stage?
SPANGENBERG:
No. They didn't have any accidents but then they never flew very much. In
fact we didn't have any accidents. They were powered with T-40 engines. The
Lockheed airplane looked more like an airplane and it had dual upper V and
inverted lower V tail surfaces with small aft landing gears on each tip.
It landed vertically on the four tail tips.
The Convair was a more
stable platform because the wing span was greater than the Lockheed tail
spans. The ground contact points were further apart on the Convair.
The Lockheed airplane
only flew after taking off and landing in a horizontal attitude with a big
jerry built landing gear added to it. The T-40 engine was certainly not the
world's most reliable and the pilot's life depended solely on that engine
working. You had no possibility of auto rotation as you have with the helicopter
so anytime you got into the vertical mode you were really depending on that
engine continuing to work. Another factor was that as you got close to the
ground the tail sitters lost control effectiveness due to ground proximity.
Ground effect in essence helps on landing speed but does not help in the
VTOL mode. That led to ideas for landing and take-off from a perforated area.
I went to the mockup on
the XFV. Very strange to sit in the cockpit in the vertical attitude. Your
view of the ground obviously is awful. I didn't see how they were going to
do a landing unless they built a tower of some kind that a pilot could see
by looking sideways. At least they had to have better necks than I had.
RAUSA:
Was the original concept they had like rear view mirrors. Did they use those.
SPANGENBERG:
We had big rear view mirrors. Just like backing up an automobile except you
can't open the door, or help with your body turning around. One could imagine
landing aids that would help. You'd have some kind of a scaffold arrangement
and a landing target that you could line up with something. But as I say
Lockheed never got to vertical landings. Convair did on a few flights but
the airplane really had no place to go. It finally dawned on everybody that
you just can't build an operational fleet vehicle with a tail sitter arrangement.
You try to think of how the hell do you handle it. For example, you'd have
to put it in a horizontal position to work on the engines. That program died.
I really don't count it as one of our failures because everybody really considered
it to be a research vehicle, although we sure didn't need two.
The next step after that
was to do a jet VTOL. The Navy actually started along that line. The project
ended up with the Air Force doing it with a Ryan Wire Hanger. Did you ever
see the Wire Hanger? What was it, the X-13?
RAUSA:
No.
SPANGENBERG:
It had a carrier truck about as long as a fire engine hook and ladder. The
plane could be raised from a horizontal to the vertical, held on a big wire
mesh arrangement. The pilot used a hook for recovery not unlike the old
CAST recovery hooks that we had on seaplanes. He got to the vertical, flew
horizontally, translated and finally grabbed a horizontal cable as the plane
dropped down. They put on demonstrations of that in the local area. I remember
going and watching it at the River Entrance of the Pentagon and at the time
they had a bunch of rose bushes growing down there along the road. The recovery
vehicle was sitting down there. The airplane took off from the recovery vehicle,
translated over the lagoon. You could see the water whipping up in the typical
pattern that you get from the down flow and then he came back and landed
on the net. Destroyed about $100 worth of roses, just ripped them out of
the ground. [laugher]. That was a successful research program but the Air
Force couldn't figure out what to do with it.
At that point in our history
VTOL and V/STOL enthusiasm was running very high. When turbo-prop engines
became available, it became possible to provide more thrust than the take-off
weight of fighters, for example. The enthusiasts then sold, or tried to sell,
the idea that the advantages of VTOL were now available for all of naval
aviation. I remember Capt. Stevens, after being briefed by Mr. Driggs on
the results of some tethered model testing at the NACA, coming into the office
with Mr. Frisbie and me, and telling us he expected that we should have an
all VTOL carrier complement within ten years. That gross over-optimism actually
surfaced again in 1977 when "Proceedings" published an article under then
CNO Holloway's byline proposing an all V/STOL force, since he had been advised
that the state of the art now permitted that goal with no significant penalty
over conventional aircraft. That belief is as erroneous now as it was in the
50's and 70's.
TAPE 8 of 16, SIDE A
JULY 25, 1990
RAUSA:
Now up to time period of about 1952, talking the P6M. Mr. Spangenberg has
his notes neatly laid out here in preparation for this briefing. [laugher]
SPANGENBERG:
There are always things that I think about that were interesting items that
come with it. That's really all we're doing. The things that were a little
unusual at the time.
The P6M was the last cry
I guess of the -- maybe the first too -- of the real high speed attempts
with a seaplane. It was not popular at the working level with most of
the engineers but it was with some. I don't know whether you've heard
of Fred Locke. Fred Locke was a very unusual airplane designer, seaplane
background type, and he had been laying out things in the old Research
Division, preliminary design outfit, and he had one high speed seaplane
thing in which the airplane would land upside down. It had a rotating
cockpit in the thing and that way he was able to achieve a lower drag,
high speed hull design. I can't remember the details but it was a good
looking design. Probably impractical.
The P6M was a strange
competition. There were only two designs in it. Convair and Martin and it
was one of the first where the Navy thought one design was way underweight
and the other one was way overweight. We often had them where we thought
the contractor was understating what the weight of the airplane would be
but in this case we were sure that Martin was way under and we were sure
that Convair was way over. There was something like a 20,000 pound difference
between the two proposals. We couldn't accept either one so we did a debriefing,
sent them back to the drawing boards and they came in with a second proposal
and Martin was selected to win in that one although you could have flipped
a coin, just about. It was also the first competition in which we had to
take the briefing of the competition results up to the Assistant Secretary
for Air in those days what would be today the R&D Navy Secretary. Floberg
was also an aviator. I suppose that's the real reason we got up to his level.
Up to that point in time we had never gone beyond the uniformed Navy in a
competition.
The P6M itself of course
was not a success. They lost two of the airplanes in accidents. The tail
came off one and I forgot what happened to the other.
RAUSA:
Were there more than two?
SPANGENBERG:
We built more. They had more than two under construction. It was a concurrent
program so they probably had five or more of them under construction at
the time. In my opinion the requirement was just nonexistent. The basic
mission was supposed to be to deliver 30,000 pounds of mines. Had a rotating
bomb bay which was part of the hull which obviously would give troubles
in service anyway to try to get that thing sealed. Never did get around
to that, really working out that part of the airplane as I recall. But
in any event, the joke that -- I remember Bob Francis, the A3D Class Desk
officer. He and I used to talk frequently about airplanes and whatnot
and our favorite story on the P6M was we could buy two A3Ds to do the
job and they would cost less than one P6M. Would do the job better and
the thing we didn't realize was we could buy the carrier to operate the
A3Ds from the money we had left over. That was about it. It was the last
of the seaplane, at least the high speed kind of seaplanes.
The next interesting one
I guess on here is the F11F and the money for getting that came out of the
cancellation of the F10F, the variable sweep design that we talked about
before. We had money left over and they called it the XF9F-9. It was a brand
new, well designed airplane. It was a little too early to start a new fighter
with the next generation of engines, the J-79 and the J-57. But Grumman did
a good sales job. It was not a competition. It was a negotiated procurement.
Joe Gavin who later became president of Grumman was working on the board
at the time. That was an interesting tale too. Joe had been in the fighter
desk at the bureau. He was number one in his class at MIT, smart guy and
a real nice guy. When the war was over he got offers from virtually every
airplane outfit in the country I guess to go with them and they all were going
to make him a program manager. I and perhaps others advised him he better
get his hands wet first and Grumman was the only one that offered him a job
where he would start on the drawing board. Joe took that job. You really
learn more quickly, I think, how airplanes are designed and what makes a
good one by working on the board. So Joe did the powerplant installation
as I recall on that. Later became project engineer on the job. Later became
president of Grumman. Good guy.
RAUSA:
When you say it was a negotiated procurement how does that differ from the
normal bidding process?
SPANGENBERG:
Well, you don't bid. The contractor comes in with a good proposal and you
just buy it and then attempt to justify why you do it. Later on today we
ought to talk about the beginning of the A-4 which was done the same way.
RAUSA:
The F-11F you say was a good design?
SPANGENBERG:
It was an excellent aerodynamic design. It just didn't have the engine that
it should have had right from the beginning. Grumman couldn't really afford
to try to achieve the level of performance that the Navy was likely to want
for the next fighter so it was really regarded as an interim step between
a truly supersonic fighter. It was supersonic but just mach1.1 or 1.2, something
like that. It was regarded as an interim fighter but the aerodynamics of
the airplane were excellent and it was a well laid out design. Didn't have
quite enough fuel in it.
RAUSA:
Do you recall how many we bought of those? Did we have several squadrons?
SPANGENBERG:
We probably had four or five squadrons I suppose.
RAUSA:
Did they have missile capability?
SPANGENBERG:
Yeah. Sidewinders. But it was primarily a gun fighter. It was the one that
shot itself down, probably one of the stories you should have heard about
in the fleet. Testing the guns in a dive, the airplane ran into one of its
bullets.
RAUSA:
How did it do that?
SPANGENBERG:
Well, I suppose it had a high trajectory bullet and the airplane caught up
to it.
RAUSA:
Did the pilot survive?
SPANGENBERG:
Yeah. It was a famous story for awhile. The main reason the airplane didn't
go anyplace was the engine was a grand flop basically. There was really no
engine in this country --
RAUSA:
Which engine was it?
SPANGENBERG:
It was an afterburner version of the British Sapphire. Curtiss Wright had
the license to build the engine. It existed as a non-afterburning engine
but for the F11F they had to develop an afterburner to put on it. That development
lagged and they had engine development problems. The first couple of airplanes
as I recall flew without the afterburner and then gradually they got the
thing running. The designation was J-65. It was not a good engine. At the
end of the program J-79s were put into the airplane on an experimental kind
of a basis. Grumman had I think two of the airplanes and it was a Mach 2
plus airplane and a very high performance machine.
In the international arena
Grumman tried to sell it to Japan in lieu of the F-104s and there were sales
efforts in Germany as well. Both of those countries would have been well
advised to buy the F11F-2 we called it then, Tiger King.
I remember Gordon Ochenrider
who was Grumman's sales guy at the time. It was before he got to Washington.
Gordon would come back from his attempts to sell it and he was just completely
naive in the international field. The story was that he wasn't paying the
bribes that others were, trying to handle it honestly. He didn't sell the
airplane and it was a far better airplane than the one against which he was
competing. My opinion.
Well, the next one on
the list is the A4D and it's probably been well enough covered by everybody.
I glanced at Heinemann's recollections on the start of the airplane and as
I remembered it there was a lot more effort initially on Ed trying to build
a fighter interceptor type, very high performance and again it turned out
that the Navy just didn't have a big enough market to interest Douglas really
in developing such an airplane or the Navy in buying one. You'd like the
performance but the interceptor really couldn't quite do the job. Deck launched
intercepts against the high performance threat didn't quite hack it and then
you didn't want to invest that kind of a deck space in trying to buy just
a small capability.
Anyway at the same time
the Navy had been trying for a long time to get a replacement for the AD
started. Douglas itself had study contracts for follow on to the AD, all
using turbo props. 557 program I think it was and they were ugly airplanes
and not at all attractive. I see Heinemann said that they were all in the
30,000 pound bracket and I suppose that's right. I don't remember. But I
know that they were not attractive. Finally he turned the thing around and
made it really the first jet fighter attack design. It was a nice little
airplane. Everybody liked it. The thing I remember most about justifying that
procurement was writing a letter from -- I suppose we had to write to CNO
or maybe to the Secretary or somebody to justify a sole source procurement
rather than having a competition and the thrust of the letter was it would
be unfair to industry to have the competition because Douglas was so far
ahead, had already spent so much money on it and the chances of it turning
out to be a better airplane or a better deal than we could negotiate with
Douglas at the time was very remote. Blackie Kennedy was the OPNAV sponsor.
He was a project guy on attack planes in what's now OP-506. He was a good
guy too. There were such excellent working relationships within the bureau
and with the CNO at the time.
RAUSA:
It was less bureaucratic, right?
SPANGENBERG:
Much less bureaucratic. Whenever there was any kind of a problem the OPNAV
guys would be over with BuAer or BuWeps whatever we were then. I guess we
were still BuAer and always in close communication and worked together without
a lot of paperwork.
RAUSA:
Was the A4D -- did you think it would be the great success it was even
then at the outset?
SPANGENBERG:
Well, I don't think any of us thought any airplane was going to last twenty
years or twenty-five years in production. Up to that point in time you were
developing engines on maybe a three to five year cycle and the next engine
development then went into a new airplane development to take advantage of
it. Of course we finally reached a plateau where you couldn't make much of
a jump in airplane performance and the engines had kind of flattened out
too. That really explains it I suppose. We were not having the kind of step
improvements that you had been getting all through the reciprocating engine
days. But nobody thought any combat airplane would last twenty-five years.
There were a couple more
helicopters that year but we can skip those.
1953 saw the beginning
of the F8U program and that was an excellent competition after we got it
squared away. A big competition. Called a day fighter and the armament at
the beginning was guns, and/or collision course rockets. It carried sixty,
two inch, air-to-air rockets. The rocketry stuff never did work out. Within
that competition __ well, the beginning was very strange. In that
article I wrote for the Gold Book I pointed out that they
had asked me to write on long-range planning which really never has worked
anywhere that I know about. Pete Aurand was the project officer on the fighter
desk and Pete was one of those that believed you needed nothing but subsonic
performance and simplicity would be the big thing. Do it better, turn better,
the air combat arena and whatnot. So the competition actually started as
a subsonic airplane. Fortunately -- I suppose fortunately -- Pete got detached
and went to his next tour and as soon as he got out of the bureau I think
within the next week a simple change went out to all of the bidders saying
change Mach .9 or .95, whatever it was, to Mach 1.2. So it became then a
true supersonic airplane. The minimum speed requirement was 1.2 and most
of the designs came in over that.
Vought won the competition
hands down. Their big competitor in a sense was North American. It was strange
in that not unlike the P6M competition we knew the Vought design was underweight
as proposed. It was in the low 20s, 21,000 or thereabouts for design mission.
But North American came
in close to 30,000 pounds for an airplane that was almost the same. They
each had variable incidence wings. They were necessary in those days in order
to solve the angle of attack problem and get back aboard in the best manner.
That was part of the reason too for the A4D's long legs in addition to getting
enough ground clearance. You had to get enough angle of attack in order that
Delta wing could get up to a decent lift coefficient.
Back to the F8Us. We had
variable incidence on the two principal proposals. In our mind Vought was
going to be something over 1,000 pounds overweight but even at 1,000 pounds
overweight or 1400 or whatever it was we thought it would still be a better
airplane and perfectly acceptable in the fleet. North American at 30,000
pounds though would be about where we thought that the airplane might end
up as a top of its growth line and there it was starting that way. And obviously
if you propose a 30,000 pound airplane you can build it. Eventually we decided
that we had to go with Vought. It was a better airplane of all those that
were proposed. Later Lee Atwood, then president of North American and a very
fine engineer, was convinced that the Navy had given the contract to Vought
because they needed the business. He gave a speech before probably the Industrial
Preparedness Association, one of those trade organizations, and in his written
version of the speech there was nothing in it about that competition but
as he actually gave it there was a paragraph added on the Navy's way of doing
business or the military's way generally speaking of having design competitions.
He said design competitions had to be run honestly and that the evaluators
had to put aside any thoughts that they were trying to regulate the economy
of the country and so on and just pick the best design. From the manufacturer's
standpoint winning the design competition was the key to getting a production
contract which was a reason that they were in business. An airplane company
could not exist on experimental contracts alone. Everything that he said
was right down our alley. We thought we had done exactly what he had asked
for and for a number of years I quoted that paragraph of his whenever I gave
a source selection briefing to anybody. Atwood didn't know it but he was
outlining the rules of the game as we thought they should be played.
RAUSA:
But in his own way he was complaining.
SPANGENBERG:
He was complaining. Well, as you know that one went on to become a great
airplane too and one that should have been bought in large numbers overseas.
We sold some to the French. Later on, another country, I believe the Philippines,
picked up some refurbished F-8Hs.
RAUSA:
Was that a Mach 2 or 2 plus?
SPANGENBERG:
No. It started as a 1.4 and I don't think it got up to Mach 2.
RAUSA:
This was the first variable incidence wing aircraft that you had dealt with,
is that right?
SPANGENBERG:
Yes.
RAUSA:
Did that present any special problems?
SPANGENBERG:
Not really. People were worried about it. Mechanically it's very straightforward.
It's no tougher than folding the wings essentially.
RAUSA:
I mean the aerodynamic aspects weren't worrisome?
SPANGENBERG:
No. One of the reasons, it was a high wing airplane. It would have been tough
to do a variable incidence with a low wing airplane. Get sealing problems
and so on. The high wing airplane it didn't really bother very much. Of course
you also wanted the high wing low tail for getting through Mach 1. Good airplane
and successful development and the timing of the program we used for years
as the way you ought to develop an airplane.
Unfortunately some of
the think tanks around the country and the people who were not close to the
actual development, claim that the F8U was a prototype because we had two
airplanes labeled XF8U-1. So in one of the big studies done by RAND years
later, they came to the remarkable conclusion that it cost neither time nor
money to prototype, test and then buy. And the reason that they came to that
conclusion was that they did not properly separate prototype programs from
concurrent programs and since there was an XF8U-1, they included it in their
prototype kind of a program, but it was really concurrent from day one. It
had all been planned that we let the first contract for two airplanes but
then within the next year we bought five and then twelve and then twenty
or something in order to get a smooth production buildup. We bought enough
experimental or early production airplanes to get the test flying done. If
you have two airplanes it takes forever. And if you do them as pure prototypes
you've cut corners all through the thing and you don't have a representative
sample. I probably have a hell of a lot more to say, don't have to say it
really, but I'll give you some of the prototype papers and articles that
were written because it's an important part of the acquisition process. People
should know that we stopped prototyping before World War II. The F4U-1 Corsair
was the last fighter that we did prototype before ordering it in production.
TAPE 8 of 16, SIDE B
I guess that's the end
of this quick prototype thing.
That was the only airplane
we started that year according to my chart. Starting in '54 was a very unusual
competition of things that were marked helicopters ROE and RON. This was
another crazy Marine idea. [laughter] They were going to put every Marine
into the air so we had one-man helicopters. You could put them under your
arm and carry them around with you. Assemble them in the field.
RAUSA:
Observation helios?
SPANGENBERG:
You could go to war with them I guess. If a Marine got trapped anywhere you'd
drop him one from a airplane, he quickly assembled it, read how to fly in
one easy lesson and took off. They thought they'd give Marines flight training
in these little helicopters. Every Marine would get one. It was a weird competition.
We had about forty-some entries of all sizes, shapes, descriptions and ended
up __ this was ROE so it must have been Hiller was one of the
ones and the other one was Gyrodyne Gyrodynes were little coaxial machines.
They were weird. Obviously the thing was a complete fiasco.
RAUSA:
Did they fly some of these?
SPANGENBERG:
Yeah. They flew. Other people got into the act too. I remember Goodyear built
one.
RAUSA:
These were open cockpit?
SPANGENBERG:
Yeah. You just sat out there in the breeze with a stick in front of you and
the rotor kind of strapped on your shoulders [laughter].
RAUSA:
You guys must have gone crazy.
SPANGENBERG:
We did. That was a busy year too. F4H got started that year also. Lots of
things were going on. Eventually the Gyrodyne thing -- or modification of
it -- became the DASH drone helicopter. Another program. The DASH was the
first radio controlled helicopter program and it probably would have been
a success if the Navy had been smart enough to put a total aviation unit
aboard the ship and operate the drones as well as doing the job of building
and furnishing them. But the concept sort of had the surface fleet personnel
doing the operation and they just didn't have enough training.
RAUSA:
Well the DASH lasted for a while.
SPANGENBERG:
Oh it lasted quite a while. But the Marine one-man helicopter didn't. It
was a screwy one. The F4H also finally got underway that year. That's covered
to a degree in that Gold Book article. McDonnell was running out
of F3H production so they were submitting proposals once a month I guess
on another version of the F3H. We were still calling it F3H. F3HA, B, C,
D, E, F, G, H -- finally got up to H. Good selling job by McDonnell. The
bureau fought against the idea because it was a year too soon to start a
new fighter.
RAUSA:
What was the fighter outfit?
SPANGENBERG:
F3H and F4Ds.
RAUSA:
They were the main fighters.
SPANGENBERG:
Fighters in the fleet. The F8U was still in development. We ran an informal
competition. The final McDonnell proposals were gunned airplanes, 4-20s,
still single-place and the F3H-G was a J-65 powered airplane. The F3H-H was
a J-79 powered airplane. In those days we did not allow an airplane to start
until the engine had reached PFRT which is a preliminary flight rating test,
fifty-hour test on that engine. If you did that by the time you got to your
full qualified engine test you had a production airplane ready to go. It
was a good concept then and would be now. McNamara screwed all that up because
he insisted on a total package approach. Couldn't start an engine until you
started the airplane and you had to wait for the war to develop before you
could do that.
We did an informal competition
as it were but without getting formal bids from anybody. We had proposals
at the time from a number of manufacturers. Probably the early F4D-2, the
design that became the F5D.
RAUSA:
Sky Lancer.
SPANGENBERG:
Yeah, later. Was in hand. There was a Grumman proposal that had jet engines
plus a rocket in it. That was laying around. We hadn't really done anything
with it. And all the McDonnell designs. Those are the ones I remember most
clearly.
The F3H-H used two J-79s
but as I said we weren't ready to specify that engine yet. The performance
of the airplane with two J-79s was excellent. Two J-79s would make any airplane
pretty good. Their F3H-G was the same airplane but with J-65s, a much lesser
engine. And it was a lousy design I thought.
RAUSA:
Did it look like the F-4?
SPANGENBERG:
Yeah. More or less.
RAUSA:
It just looked unorthodox, didn't it?
SPANGENBERG:
The F4H as it started didn't look quite as strange. Didn't have the droop
tail yet and the wings didn't have the broken wing look that they eventually
developed. But it was a single-place airplane and armed only with guns. But
a hell of a lot of pressure from the industrial statesmanship side of the
Navy organization, as well as from McDonnell saying we have to have something
to keep the factory going and so on and so forth. I remember writing the
memo, it's back there in Navy files somewhere, that the only way you could
possibly justify the F3H-G was to buy it as a stepping stone while you awaited
the arrival of the J-79s which as it turned out is exactly what they ended
up doing. And manipulations that I wasn't involved in ended up then with
them giving a contract to McDonnell for the AH-1. Lo and behold it had become
an attack plane. An afterburning twin engine single-place attack plane. A
type that didn't exist in any plan that I knew anything about. Short on range.
Very strange and I don't know how it all happened. After about I suppose
six months there was a big reconfiguration study and the airplane then was
changed over to that which we know today. Became a two-place airplane, no
guns, except in a pod and armed with four Sparrows as primary armament with
a fair amount of emphasis still on the air-to-ground mission.
RAUSA:
In other words you were thinking in terms of a fighter/bombers not just a
fighter.
SPANGENBERG:
All of our fighters have been fighter/bombers. They ended up that way. They
started as fighters. If they were good they had enough capability to carry
bombs, F6Fs had always done it, F4Us had done it. I think everything had
done it. We hadn't had any pure fighters. The only one that stayed pure I
guess was the F-8.
RAUSA:
I think they did some bombing with the F-8.
SPANGENBERG:
Probably shot rockets with it. I guess you could rig up bombs somewhere.
RAUSA:
On the in-board wing maybe.
SPANGENBERG:
But it stayed purer than most. Anyway, the Class Desk officer, I think Charlie
Smith started the thing.
RAUSA:
Was Julian Lake in there somewhere?
SPANGENBERG:
Julian was probably in electronics at the time or he had been anyway.
In the early development
part of the game C.B. Smith or maybe Frank Timmes was the first project officer.
Anyway, the big hassle was could we afford to get guns into the thing in
addition to the Sparrows and we couldn't afford that extra thousand pounds
and still get it on and off the boat. It ended up without guns and was the
two-place configuration.
RAUSA:
Did that bother you?
SPANGENBERG:
Making it two-place?
RAUSA:
Not the two-place but not having the guns?
SPANGENBERG:
Well, I think all of the operators wanted guns in it but when it came down
to the crunch you either had an airplane without guns that you could operate,
or it looked like you could operate, with the arresting gear and catapults
we had on the ships or you didn't. There was not a hell of a lot of "growth"
in the airplane. We didn't have any big margins. In fact that was probably
the most critical time then and a little bit later when we had the F4H, the
A3D and the A3J __ it became the RA5C. Those took up more catapult
and arresting capacity than the airplanes since then. I remember writing
a paper on that, doing a study of some kind. Answering a query from Ships
Installations where do we go from here? How much bigger do we have to keep
making these things? Aerodynamically it looked like it would be about at
the peak there and I guess we were.
Anyway, the F4H then got
changed from the single seat armed, gun armed, lousy, underpowered airplane
to a well powered two-place missile carrying airplane and it became the fighter
for the fleet. We didn't get the final radar until five or six years later
but that was in the works too. Everybody had reached a conclusion then that
you had to have some kind of a missile capability, that guns alone just wouldn't
hack it for the high performance threat against the fleet. So it marched
on.
About a year later the
advocates of single-place single engined airplanes rose again and we started
the F8U-3 as a competitor to the F4H. Both of the airplanes were laid out
as production programs. The F8U-3 was modeled after the F8U-1. That is, you
learned to use the aerodynamics of the F8U-1, and put the big engines, the
J-75 engine in it. It was a Sparrow-armed airplane too. Again without guns.
Vought did a superb job. The cliche after 1958 was that the F8U-3 was the
best airplane we ever cancelled.
RAUSA:
So the F8U-3 lost out to continued production of the F4H.
SPANGENBERG:
Right. Both airplanes were scheduled for production and were designed with
superb programs. Vought did a better job in development than McDonnell did.
They started perhaps a year afterwards and flew at almost the same time,
first flight. And then Vought did a much better job of fixing things up that
showed up in flight test. In 1957 Congress was screaming. We had to cancel
one. Up to that point in time the Navy had never had less than two fighters
in production at the same time. Jim Russell was Chief of the Bureau and he
testified that we can't afford to ever get down to having our fleet defense
dependent upon any one engine or any one airplane. If you have a bad episode
with one and have to ground the airplanes or the engines you didn't want
the fleet without some capability to defend themselves.
RAUSA:
Vought must have been very bitter about that.
SPANGENBERG:
Later they were. They were obviously extremely disappointed. It was just
one of many disappointments for Vought at about that time where the Navy
was really getting itself into a money crunch. But in 1957 Congress told
us to cancel one. We ran a big paper evaluation. Neither airplane had reached
flight status, and finally got Congress to delay it a year. By that time
we had flight tests by PAX and could make sure that our paper estimates were
all right. In the normal sense the F8U-3 won the fly-off. It had by far the
best flying qualities. It was the best flying airplane, best flying fighter
at least that the Navy had ever developed according to the PAX reports. Good
flight control system. It carried only three Sparrows instead of four as
a compromise in trying to get the best airplane. It would do everything on
internal fuel that the F4D did with a 600 gallon tank. It had better legs.
It had higher speed. Climbs were about the same. Ceilings were about the
same.
RAUSA:
Then why did McDonnell win? Was it a political decision?
SPANGENBERG:
No. It was one-place versus two-place. At the time there was a growing conviction
in the fleet that you needed two guys to do the all weather fighter job. There
was a big all weather fighter conference at Patuxent and they came out with
"a unanimous report." I can't believe that of Navy fighter pilots.
RAUSA:
The fact that it had two engines, that was important to you.
SPANGENBERG:
That was incidental in my opinion but it was an advantage. People would prefer
two engines to one engine as long as you didn't pay too big a penalty. But
the one-man, two-man decision was primary with the feeling that one man under
good conditions could do the job. You had about a twenty percent advantage
of cost with the F8U-3. But under the real tough conditions where the studies
were done and presented I guess at that fighter conference and I know that
were being done in the radar community, the F8U lost out. The kind of radar
detection ranges we had, the conversion from when you first saw the enemy
to where you could get in a position of launching missiles, it came down
to the difference of two radar sweeps that made the difference between success
and failure. You sure had a hell of a lot better chance to do that with a
radar operator, meaning two-man.
Later the decision for
two-man was almost universally accepted. Some of the biggest proponents for
single-place, white scarf flying, fighter days came back after they had an
F-4 squadron in the fleet. I remember distinctly talking with a bunch of
Israelis, I can't remember the fighter pilot's name, but he was known as
the king of single seat fighters. Hell of a nice guy. But anyway,I said,
"Commander so and so won't agree with me but I thought the right decision had
been made." In fact I wrote that in that F8U-3/F4H evaluation memo: "The
day of the single seat fighter is over. Let's not make this mistake again.
To develop a whole airplane around that concept, have it turn out to be a
better airplane and then not buy it. We shouldn't do that again."Anyway, we were talking to the Israelis, and they brought up one-man versus two-man,
they were probably getting ready to buy F-4s at the time. When I made the
statement the Commander said, "I don't disagree." He said, "having that
second guy in back, radar operator, is just like having a wing man who doesn't
get lost." Even in the air combat arena that second guy was worth his weight
in gold. So as far as I was concerned I thought that the decision had been
made in perpetuity that we would go with two-place. And it was of course
then for the next twenty years until the F-18 came along.
Those were tough times.
It was tough for Vought. I guess I didn't mention when the F8U-1 was selected
one of the big "disadvantages" of Vought was that the fact that they had
just screwed up the F6U or should never have started the F6U and then the
F7U was anything but the world's best airplane. So there were a lot of people
that said don't give Vought another one. But it really proves that you have
to make a decision on the basis of the design proposals in front of you and
not on the record of what they did the last time because every one of the
manufacturers has screwed up at one time or another. And in fact if they're
about to go out of business they'll do a lot better job for you than the
guy that's sitting there with two or three projects on the back burner while
the first team works on the one that is further ahead. That's some of my
philosophy. I don't think it's worth talking about it any more.
T-34 was an off the shelf
type of deal. It was interesting in those days for me, a non-aviator, to
listen to pilots talk about their early training and what they wanted to
get out of it. They didn't want a very complicated airplane for primary flight
training. They really wanted the wind in the face feel, and so you would
learn to enjoy flying as opposed to having a complicated procedure that you
worried about all the time.
RAUSA:
But the T-34 had already -- wait a minute, what year are we talking about?
SPANGENBERG:
It's '55.
RAUSA:
So they just started coming in.
SPANGENBERG:
We talked about the F8U-3 where the actual start was in '56. There was the
HU2K Kaman's entry into a major fleet requirement for the first time. And
that was a competition which I thought and Pete Brown, the rotary wing desk
officer thought that Vertol had won the competition. Tommy Thomas was the
aircraft division officer at the time. He had been involved in the AD and
the A3D and the A4D. Good friend of mine. But he was also a good friend of
Charlie Kaman. The Kaman helicopter as proposed had a very wide blade rotor
system. Our aero and structures guys didn't think that it would work. They
were going to have a bearing-less rotor, using technology from the oil well
drilling experience or something. Tommy won the argument on who won the competition
and so they bought the thing from Kaman. It was the highest speed helicopter
we had at the time but the rotor system got changed to a more conventional
one and that oil well experience was dropped.
RAUSA:
Was it a prelude to the Sea Sprite?
SPANGENBERG:
It was a Sea Sprite. It started as the HU2K. It had a long successful experience
but we thought, Pete Brown and I, that Piasecki won the competition. I still
think they did. [laughter]
The TT-1.
RAUSA:
The Temco Pinto.
SPANGENBERG:
And the T2J. The T2J came out of a big training study done at the time. Getting
a new basic trainer. It was a well thought out study in a well laid out procurement
plan to buy the T2J. Enough airplane work at the study level had been done.
TAPE 9 of 16, SIDE A
RAUSA:
You had just said that North American won the competition.
SPANGENBERG:
Won the competition. It was around a J-34 engine, single engine airplane
as it started and went on for a while. T2J-1 was redesignated as the T-2A.
It was a successful development and it's had a long life. We're still flying
T-2s. The twin engined T-2B with J-60 engines followed after a couple of
hundred T-2As.
At the same time at the
very last minute Temco had been trying to sell that silly little TT-1 thing
as a jet primary trainer. OPNAV approved the plan as an adjunct to the T2J
and we bought a dozen or so for tests as primary trainers. We hadn't done
our homework, studies hadn't been done and the bureau was scarcely involved
in the decision.
RAUSA:
Where are they located?
SPANGENBERG:
At the time they were down almost next to Vought in Dallas. You remember
later that they became Ling-Temco Vought (LTV). Ling was a financier type,
and the owner of Temco.
RAUSA:
Well we actually bought some Pintos, didn't we?
SPANGENBERG:
Not many, shouldn't have.
RAUSA:
They went into production or we just had some experimental?
SPANGENBERG:
It may have been a production program right from the beginning but it was
a slow buildup type and we didn't buy very many (14 total).
RAUSA:
What was the main problem? Was it underpowered?
SPANGENBERG:
Grossly underpowered. You went through a mud puddle and it flamed out the
engine. Literally.
RAUSA:
Did we hurt some people in that era?
SPANGENBERG:
No. Eventually the guy that's now president of Gulf Stream, his name was
Paulson, big promoter. He later bought some of those TT-1s and some years
later did a demonstration out at a Dulles air show. He was trying to sell
an upgraded version to the Navy. He was unsuccessful, and we didn't buy the
scheme. He had a few of them flying around. He was trying to sell it commercially
and to any military training outfit that was willing. When he flew out here
at Dulles he tried to do a high speed dive and pullout, but the canopy came
off, hit the tail. I don't know whether the pilot got out or not but the
airplane crashed.
RAUSA:
Before we go any further, with respect to yourself George has your title changed
over the years? Are you still the weight guy now?
SPANGENBERG:
The weight thing for me was always incidental. I did the weight estimating
but I did not run the weight control program and after World War II we had
competent people in the weight group that did weight estimates. I continued
to do some of my back of the envelope thing just to satisfy myself that we
were always in the right ballpark.
RAUSA:
What was your title at this time?
SPANGENBERG:
I had lots of titles over the years. I became "Director, Evaluation Division"
in 1957; before that I was "Assistant Director." But I was also in Contract
Airplane Design all during the period when I was involved with approval of
drawings and that kind of stuff. And running the competitions was also Contract
Airplane Design responsibility.
RAUSA:
So you're dealing an awful lot with --
SPANGENBERG:
We were looking at the whole airplane from the time I went to Washington.
I would not have come to Washington looking at a piece of the airplane. I
would rather have gone to industry or stayed with NAF where you had a better
feel. I didn't want to get into details such as only ejection seats, or only
powerplants. In fact the powerplants is worse than that, it could be only
development of engines or development of intake systems, accessories or fuel
tanks. I didn't want that. So I've always been a "generalist." That's a guy
who knows less and less about more and more until he knows nothing about
everything. But I knew enough about all of the disciplines that I could talk
to our performance people, the flying quality people. I could talk their
language. I had more trouble talking the electronics language so I really
had to depend a lot more there on the people I knew from their reputations
and their experiences. I depended upon them. The Puckets and the Plunkerts
and Chuck Francis when he was down there. To a far greater degree than I
had to in the airframe part. I could argue with a structures guy. To a degree
I could argue with some of the aero guys though I really depended upon them
for specific performance numbers and flying qualities.
When we ran a competition,
for example, or any time during the program I probably had more to do with
what the performance guys were working on then did their division director
because we would get requests from CNO or from the Secretary of the Navy.
We had one from Kissinger, "Kissinger Wants to Know," when he was national
security adviser. It took a big study to get a lot of performance data, and
of course, he wanted it immediately or sooner. Our Assistant Chief had let
me often control the workload of the performance people. If I told them it
was more important to do the design competition than it was to get the performance
chart out on some airplane they would shift their priorities and all work
on the competition.
I believe I also had a
very close working relationship with all those working level guys in our
technical community. Unlike too many, if I wanted to find out something from
the performance group I walked down there and talked to them and they would
come up and talk to me. When we'd have a "fire drill" at night often the
performance guy working on it would come up to my office, we'd sit down and
do twenty or thirty radius problems, for example, to satisfy some congressional
request or something. So I was kind of coordinating the airframe part of
the game.
You really couldn't differentiate
some of what I did from what a class desk officer's job description said.
We worked very closely together. Each understood the other. The working level
really understood the whole system better than our Assistant Chief did.
Adm. Schoech never did
figure out what I did and what Fred Gloeckler did. He would telephone me
and I'd run down to his office and he'd give me a job. At first I would tell
him this is really Fred Gloeckler's job. He did the same thing to Fred. Finally
instead of doing that, going back and telling him, he'd give me a job and
I'd give it to Fred if it was Fred's. Fred would give it to me if it was
mine.
RAUSA:
Was Schoech BuAer or Assistant Chief?
SPANGENBERG:
He became Assistant Chief of the Bureau, but at the time I was talking about
he was Assistant Chief for R&D.
Schoech went from R&D
assistant chief out to the fleet, the 7th Fleet I guess, and then when he
came back he became assistant chief.
RAUSA:
Eventually he became OP-05. I think his picture is on the wall there.
SPANGENBERG:
Could be. Yeah, he was. He was OP-05 for a while. He was also CNM. He was
our first Chief of Naval Materiel. Schoech was a wonderful individual. We
always said he couldn't spell his own name. We all liked Schoech. Schoech
always supported his working level guys. You never had any question but he'd
be on your side. If we were going to argue with the Air Force, Schoech could
always be depended upon to support you. When Gelantin took over for Schoech
you couldn't always depend on him. He didn't back up our numbers. We got
into serious trouble during F-111 days. What he did in a big meeting with
McNamara's crew was to substitute his judgment for ours. We had Navy numbers
for the performance of the F-111B. We also had contractor numbers for the
performance and we had Air Force numbers. Air Force numbers were always just
a little bit worse than contractor numbers. Our numbers were a lot worse.
Gelantin said, "Well since the Navy numbers are under the contractors numbers
and the Air Force is in the middle we'll believe the Air Force. And that
was wrong. And we knew it was wrong because we knew the Air Force numbers
were not those of their own performance analysts. God, I was angry.
RAUSA:
Still are.
SPANGENBERG:
Yeah. The working relationships between the civilians and the military, it's
a two way street. If they were going to respect us or expect us to respect
them they've got to respect us and in my experience we never had a problem.
I shouldn't say never but 99 1/2% or so. Naval officers and civilians got
along very, very well. Far better than in the other services.
Well, back to our models.
A3J came along after the T2J. It was a fairly closely held beginning of a
program.
RAUSA:
Was it originally slated to become a nuclear model?
SPANGENBERG:
The thing that started it was a continuing series of studies of North American
on a thing they called Nag Paw which was a subsonic low flying airplane, attack
airplane. They carried on with that, it must have been for a year and never
got to the point that it sold. Suddenly, suddenly to me at least, the supersonic
version of Nag Paw arose, directly from North American. Linear bomb bay,
God, we had never even heard of a linear bomb bay.
RAUSA:
What is a linear bomb bay?
SPANGENBERG:
You eject the bomb out of the rear of the airplane. Just have a long tunnel.
When you pushed the button the bomb ejected backwards at roughly the speed
of the airplane.
RAUSA:
Was that for a horizontal delivery?
SPANGENBERG:
Right. And it eliminated the problem of opening bomb doors at supersonic
speeds which had not been very successful. It hadn't been very good at high
subsonic. We had trouble -- most airplanes had trouble -- we had trouble
getting bombs out of the A3D initially. Then they finally put a deflector
plate or something that cleared it up. The supersonic guys were having trouble,
that were trying to solve the same problem. So this was an answer to a single
problem. You got kind of screwed up with what to do with drop tanks and the
drop tanks finally got stuck on the end there and you ejected those before
you ejected the bomb.
The A3J program started
with -- as far as I was concerned, it kind of arrived on the scene. The OPNAV
officer was Roy Eisner, later head of Patuxent. A very emphatic strong-willed
guy. He was convinced that unless we had a supersonic nuclear delivery capability
that naval aviation would disappear. It was one of those time spans again.
And so the airplane was really justified by others. We evaluated it to make
sure that it would go on and off the boat.
RAUSA:
It was a beautiful airplane.
SPANGENBERG:
Best looking airplane we ever did.
RAUSA:
Two engines.
SPANGENBERG:
Twin.
RAUSA:
Did they have a BN or RIO in the back? All you had was two little windows
back there.
SPANGENBERG:
The bomber did have a 2-man crew. Eventually it became the reconnaissance
airplane, with a reconnaissance capability orders of magnitude better than
anything we had been able to do before. We always had photo versions, probably
every one of the fighter airplanes.
RAUSA:
So it was better than the F-8, better than the Crusaders?
SPANGENBERG:
Oh, yeah. It was orders of magnitude better. Bigger cameras and electronic
reconnaissance means incorporated as well. And in connection with that development
they did that reconnaissance capability aboard ship. It became a separate
unit unto itself. From an airplane's standpoint, the airplane had all kinds
of troubles. Detailed little problems had been going on in North American
for a long time. I was never sure exactly why. They appeared not to have
enough designers that had made mistakes before. They were making them all
for us. The AJ-1 was a prime example. They put the hydraulics on top, electronics
on the bottom so the hydraulic fluid leaked all over the airplane instead
of putting it on the bottom where at least you could put a drain hole in
and let it run outside.
The linear bomb bay caused
no end of problems. A lot of the wiring and stuff had to be wrapped around
that bomb bay if you had engines on the two sides so you didn't have good
access to places to put things in the fuselage. Eventually it devolved into
a reconnaissance airplane. They attempted at the end of the line -- we had
a J-58 engine program going which was to be a Mach 3 engine, bigger than
the J-75 and the proponents of the RA5C attempted to get that next step and
eventually to compete with the SR-71. And they did studies but the Navy just
couldn't afford it. However, our J-58 engines did go into the SR-71. In the
meantime along the way on the A3J they decided to give it a super performance
capability and they played around with putting rockets on the airplane so
you got a very high performance capability for a very short length of time.
TAPE 9 of 16, SIDE
B
I think John T. Shepherd
was the first project officer on the airplane and he has remained a close
friend for a long time.
RAUSA:
This is the Vigilante now.
SPANGENBERG:
Yeah. He was the project officer at the time that they were doing this rocket
engine installation and my first experience with him was not very satisfactory.
I had written a memo after getting some performance checked and we figured
that with the radius of the airplane we were going to be lucky if we got
to the outer ring of destroyers [laughter]. The super performance rocket
just took up too much fuel. But soon we became close friends.
And we put the radome
on top of the WF. The design began on the old S2F. We got our first early
warning airplane. We had the AD-5W before that.
RAUSA:
Whose idea was it to put the dome on the top of the WF-2? Wasn't it the first
aircraft to have a dome on top?
SPANGENBERG:
It was I guess.
RAUSA:
Did that come from industry or from the Navy? The Super Connie had a dome.
Maybe that was first. Did that bother you having a big dome up there for
aerodynamics?
SPANGENBERG:
Nobody liked it but it was better than putting it on the bottom. Actually,
the radome was so large it had to be on top. I think we had tried out the
scheme on a TF before doing the real thing. We anticipated problems. I think
it actually turned out to be less troublesome than we thought it would.
The next year, '57 now,
we started the A2F which became the A-6 and that's covered in that Wings
of Gold article. If you believe in long-range planning, boy, that's not
the way to do it. The plane came out of a Marine requirement for very short
field takeoff with a couple 500 pound bombs and a 300 mile radius. The Congress
would not approve the program for the Marines alone so the Navy had to think
up a mission. The Navy thought up a long-range mission, lots of drop tanks
and 750 or 1,000 mile radius, something on that order. And the combination
really worked out very well but it's sure not any justification for spending
a lot of time on long-range plans. The original airplane had tilting tail
pipes, which could be deflected maybe thirty degrees in order to get the thrust
component acting to help offset the weight of the airplane, increase the
lift and give it an STO capability.
RAUSA:
For the takeoff and landing evolution.
SPANGENBERG:
Right. Eventually they disappeared from the production program but the program
started with those tilting tail pipes for a long time. The early airplanes
also had problems in slowing down. Well, the first problem that came up was
the drag turned out to be higher than Grumman had estimated and after we
had evaluated the thing at the competition time they had to put more span
on the airplane which helped the airplane. And then later they had to put
those wing tip speed brakes on to solve the "slowing down" problem and they
worked out well. The early speed brakes had been inadequate. The electronics
gave us all kinds of trouble in the early days and strangely enough a lot
of it was just plain connectors. Nobody had anticipated the degree of service
problems that you got trying to put those sixty pin connectors together and
that led eventually to all the potting material problems and whatnot that
we got later on. The airplane itself obviously was a great success. The Marines
dropped their short field requirement and the airplane eliminated tilting
the tail pipes. But the basic configuration gave good low speed characteristics,
and was easy to fly. Everybody liked to fly it apparently. You could get
lots of excess wind over the deck for coming aboard and taking off. The airplane
obviously had lots of growth potential. But having started it with that
requirement for four drop tanks and a big bomb to do that long-range Navy
mission we had enough store stations to handle the growth of the airplane
and enough capacity in those stations. Successful airplane. I won't dwell
on that. Everybody knows it.
The next one on the list
is a VF/VTOL which I did not talk about before and eventually we ought to
talk just one session probably on it or I'll give you some of the VTOL papers
that had been written over the years (ed: see the "V" Exhibits).
The VF/VTOL was a jet powered airplane that played around initially with
a jet powered tail sitter similar to that Ryan type in the studies. We ran
a competition. It was ridiculous. We should not have run a competition. It
was not a firm requirement. It should have been labeled as a research airplane
if we wanted to do jet VTOL. It eventually ended up with -- we invited twelve
people to bid, only two bid. In those days industry was pretty honest with
us. If the Grummans and the Voughts and the Douglases weren't bidding, that
was a good signal there was no potential in the procurement. In this case
we asked twelve guys to bid. We got bids from Bell and from Ryan. I think
Ryan proposed the Wire Hanger kind of a thing but I really don't remember.
Bell proposed a lift engine arrangement. It had two J-79 flight engines and
nine lift engines arranged vertically in the fuselage in between the two
J-79s so the pilot only had to contend with an eleven engine contraption.
It was awful. The memo we wrote from the competition was don't buy anything.
The VTOL clan however declared Bell to be the winner and we'd negotiate something
else. So for about six months they played around with the concept that eventually
the Air Force took over. It had engines on the wing tips which rotated. Two
engines on each wing tip.
RAUSA:
The XVTOL.
SPANGENBERG:
Well, we called it the VF/VTOL at the time. It never developed a designation
because we never got to the point where we thought we were really going to
buy it.
RAUSA:
Is this the one that did go on and make some carrier landings?
SPANGENBERG:
No. The Air Force took it over and developed it and they've got a number
for it, somewhere in the VF series, F series, somewhere there's that contraption.
It had tilting nacelles on it. Jet engines on the tips. I want to say J-79s
but it seems like that's too much to have four engines. I'm remembering a
four engine -- anyway, it didn't go anywhere like most VTOLs have no place
to go except for research which is fun to do because you like all the advantages
that you might get some day.
SPANGENBERG:
Then we did the Mohawk, the OF. This was a joint program with the Army. In
those days the Department of the Defense would not let the Army do any development
so when the Army wanted to start a new program they had to shop either the
Air Force or the Navy. Most of the time they seemed to end up with us, with
the Navy that is, because we didn't charge them anything for getting involved.
It had to become a joint airplane for budget justification reasons so the
Marines and the Army got together on a joint requirement. The main thing
that it provided was side-by-side cockpit with enough power. It was a pretty
good flying airplane. It had enough capability to do the bird dog job a lot
better than other things were capable of doing. We were still flying the
Cubs, the OEs and so was the Army. The Air Force really wasn't flying anything
in those days for that mission.
I still remember the Marine
guys arguing with the Army guys on whether it should be side-by-side or tandem
cockpits and some of the same argument had gone on at the early days of the
A2F.
RAUSA:
Which do you prefer? Depends on the aircraft?
SPANGENBERG:
It depends on what you're trying to do. The fighters I thought had to be
tandem just for aerodynamic reasons. The subsonic stuff, the advantages of
hand motions and communication without having to depend upon the ICS I thought
were generally overpowering and during one conference one of the Marines,
obviously one of the sharp Marines -- we were working in a working environment
where we had partial bulkheads and the guy went over into the next room and
then tried to be a part of the conference. He could hear but he couldn't
see. It was a very dramatic way to prove that you're better off sitting at
a conference table than have guys on opposite sides of a bulkhead without
any visual stuff going on.
The airplane was a great
success. The Marines dropped out of the thing in order to buy C-130s for
tanking.
RAUSA:
Are we talking about the Mohawk now?
SPANGENBERG:
Yeah. We the Navy had done an excellent job of providing a useful airplane
to the Army for close support. The Army could not put bomb racks on an airplane
because of the Air Force/Army fight about who does what. The Air Force had
not done adquate close support for the Army at any time, according to the
Army. They did their version of close support which was anything but what
the Marines call close support. In developing the airplane we had some 600
pound resupply containers which we put on wing stations. We got as far as
testing the airplane with firing the guns and dropping bombs from those resupply
container stations. Patuxent cleared the airplane and at the last minute
the Air Force found out about it and prohibited the Army from ever using
that capability. We thought we had foxed the Air Force and given the Army
a close support capability not as good as they could have had if they had
bought some Navy airplanes or had been allowed to by the Air Force but the
Air Force seemed very jealous of that. And then we got out of the program
and eventually the Army took over. The Army normally took over management
after the development because they were allowed to buy "off-the-shelf" airplanes.
We did a P6Y which was
the last of the seaplane projects and that was an ill considered requirement
to have a huge dunking sonar from an open ocean flying boat. Convair won
the competition with a three engine airplane. Had lots of boundary layer control
so it could land at maybe thirty-five or forty knots in any kind of sea state.
It then did the ASW mission by hopscotching across. You'd land, dunk the
sonar, pick the sonar up, take off and whatnot.
RAUSA:
This was all jet?
SPANGENBERG:
No, props, I think. I think it was turbo props. The old seaplane hands were
not happy with this concept. They could only foresee very, very seasick crew
members among other things and trying to land in sea state six or seven with
an airplane even if it was going slow is a very dangerous kind of operation.
We ran the competition, got the airplane and it would have been a very successful
low speed short takeoff kind of flying boat, probably with a fair degree
of payload capability as you would operate it maybe on a commercial basis
but the requirement went away very quickly with the budget crunch and they
stopped that. Thank God.
Maybe we can do the E-2
and we'll be through with that year. That started as a W2F. It was the only
competition that I was involved in that I thought was dishonest. The winner
didn't win. Vought won the competition. It was a replacement of course for
the WF-2. Bigger radar, whatnot. Vought came up with the idea of the retarded
wave antenna which allowed a thinner radome, much thinner than the WF-2.
The Vought arrangement had the radome light enough that they could locate
it at the tail of the airplane so it looked strange. But all the wind tunnel
tests were excellent. The performance was excellent. The weight, cost, flying
qualities, everything. They won the competition. The original Grumman entry
was a conventional radome with the dish rotating within it. In those days
we wrote a memorandum winding up a competition, signed by our Assistant Chief
to the Chief and via all the other Assistant Chiefs. There had been agreement.
"Okay, Vought won, we're going to go ahead", and that's what the memo said.
I went on vacation and
while I was in Hartford with my family, I picked up the paper and lo and
behold the Navy announced Grumman was the winner. I came back after the vacation
to find out what had happened? Why? And it turned out that the head of the
production division said Grumman is running out of fighters, the F9Fs were
through. They were too far away from the A2F to be satisfied with its production.
So he said Grumman needs the work and they ought to get it. The total Navy
buy at the time was something that was programmed at seventy airplanes. Well,
from my standpoint I didn't see that the Grumman production problem was going
to be solved by the E-2 by any means, what they were looking for then was
hundreds of airplanes.
RAUSA:
Are you saying you favored the Vought proposal?
SPANGENBERG:
Oh, yes. Everybody did. It was the winner of the competition. Hands down
I thought.
RAUSA:
So that was a political thing.
SPANGENBERG:
That became industrial statesmanship as it were. I was very, very upset because
I thought we had a system that worked and it worked because we were honest
and this I thought was dishonest. I pointed out to my boss, Mr. Frisbie,
who apparently had gone along with this thing because the Chief, or the Assistant
Chief or somebody said to. I think Adm. Schoech was the one that backed down.
He was our Assistant Chief at the time.
RAUSA:
Had you not gone on vacation could you have made a difference?
SPANGENBERG:
I think I would. I would have raised hell. When I got back I got told to go
pick up my memo. I said, "You've got a signed and approved memo that's in
the system and here you're giving the contract to another guy." So I got
told to go pick the memo up and I refused. I wouldn't have anything to do
with it.
RAUSA:
You had already submitted it.
SPANGENBERG:
Yeah. Schoech had signed it. So it had gone through the system and had been
approved. Finally they got one of the further down the line guys at that time,
Charlie Butt, who later became Head of the Proposals Branch. Charlie got
told to go pick up the memos and destroy them. So Charlie went and picked
them up but he didn't destroy them all.
RAUSA:
But the decision was made above Schoech then. He was told to approve that.
SPANGENBERG:
Well, the Assistant Chief for Production went to the Chief of the Bureau,
whoever that was at the time, and convinced Schoech that industrial statesmanship
should win the game.
RAUSA:
So it was a Navy decision.
SPANGENBERG:
Yeah. It was done within the Navy but I thought it was dishonest because
I said the least you can do is to say to Vought you won the competition and
we'll pay you for your efforts or something like that. But for other reasons
-- this was what we'd done on the PBB years before when again Vought had
won the competition and they decided they needed another producer in the
seaplane field but they announced that Vought was the winner, paid him for
his proposal work, turned the work over to Boeing and then Boeing submitted
another proposal that we eventually bought. And I thought they should do
the same thing.
RAUSA:
But they didn't.
SPANGENBERG:
They didn't.
RAUSA:
The Vought guys must have been furious.
SPANGENBERG:
I wouldn't debrief them. I wouldn't tell them why they lost and the word
got around.
RAUSA:
But you knew those people well.
SPANGENBERG:
Sure. They knew they had won. The retarded wave antennae gave them such an
aerodynamic advantage and no one else had it.
RAUSA:
And what this translates to was a thinner dome --
SPANGENBERG:
Eventually that technology went into the E-2. But that technology was in
the Vought proposal, it was not in the Grumman proposal so Grumman redid their
proposal eventually and picked up the Vought technology.
RAUSA:
In other words Grumman had more friends in the bureau than Vought.
SPANGENBERG:
I think that the production chief's decision was wrong because it didn't
solve the problem he was trying to solve and it screwed up our 100% record
of being honest in my opinion. You'll find that I've written this in some
of these presentations I've given. I thought that we had an honesty record
that I called 98%. We lost a couple of percentage points because of the overturning
of that decision. Other ones got overturned but we couldn't help it. The
Bell X-22 got overturned outside the Navy. The PBBl flying boat one was handled
honestly. The F-111 I didn't count because it was Air Force management and
it was overturned outside the Navy. I've got a letter still from I guess
Detwiller, then at Vought, to Jim Russell saying what the hell do we do now?
Do we still play the game? Do we get into the next competition? Are you going
to tell us whether we have a chance and so on?
RAUSA:
That must have been frustrating as hell.
SPANGENBERG:
Oh, it was and Vought ended up in deep trouble. The F8U-3 was being cancelled.
The Regulus program was being cancelled and one other thing down there. Anyway,
they were really in more trouble than Grumman.
RAUSA:
Is this a good point to stop for the day?
TAPE 10 of 16,
SIDE A
August 1, 1990
SPANGENBERG:
Okay, we're now about at the '58-'59 time period and we kind of skipped
over but in '57 Mr. Frisbie retired, my old boss, and I became the director
of the division. Gil Weiss who was then head of the weight group moved up
to assistant director. Keith Dentel took over the weight group. That basic
arrangement lasted up until around 1970 or so, when Gil Weiss retired (as
soon as he could at age 55) and Keith Dentel then moved into the assistant
directorship.
Back to the airplanes.
In '58 we started the P-3 and I won't dwell on that with an off-the-shelf
airplane basically with a follow on to the P-2 series, P2V series. Then in
'59 we started the Eagle/Missileer competition. We did the Eagle and then
later the Missileer which was a forerunner of the TFX and of the F-14. The
whole development series really started back in '55.
RAUSA:
Was the Missileer an actual aircraft?
SPANGENBERG:
The whole thing started with the threat projections being such that it was
becoming very difficult to protect the fleet against Mach 2 raids coming
in. You had to have something better than we had with F4/Sparrow capability
aircraft. All the studies said you just couldn't get there in time to shoot
down enough and the surface-to-air missiles just couldn't handle the degree
of the threat either. It turned out that studies in the mid-fifties indicated
that the state of the art in radar was such that we could do a long-range
radar search type of thing and get it into an airplane. Took about a five
foot dish to do it. This then led to probably the biggest study effort in
the Op analysis field that at least the Navy had done up to that point on
how best to do the fleet defense mission. That study was known as RAFAD and
out of that came the determination that the only real way to do the job was
with a CAP airplane and long-range missiles. It was far superior to trying
to do the high speed intercept and so on. With the threat then being projected
as Mach 2 kind of performance and launching missiles against you it was imperative
that they get stopped or at least well thinned out by one hundred miles out
or thereabouts.
At the time we started
on that the Air Force had gone the other way and started the XF-12 airplane
which eventually became the SR-71, with Mach 3 kind of performance but using
single shot missiles. That airplane as you know was a very large airplane,
100,000 pound category and very long, impossible to operate from a carrier
unless we got much, much larger carriers. That option of going that way really
wasn't open to us and also it was a very expensive way to do it. All those
Op analysis studies said that we couldn't get there from here. So Navy sold
to the Congress a program to do Eagle Missileer. Eagle was about a 100 mile
missile with mid-course guidance and terminal homing. The missile itself
weighed on the order of as I recall 1300 pounds a piece, something on that
order. Then the fire control system was being done by Westinghouse. I just
mentioned there was a five-foot dish. The Eagle missile and fire control
system part of the program started a couple years before the airplane did
and the TF-30 engine got started about that time in order to provide the
engine and the missile system in time to match the airplane. Our habit in
those days was to get the long lead items under way before you did the air
frame because really the air frame has a shorter development time required.
At the time of the Eagle competition, Grumman had won a whole batch of competitions.
They had the E-2 going on, the Mohawk going on. They had won the A-6 competition.
The Chief of the Bureau
then was Adm. Bob Dixon and he told Grumman unofficially that he didn't think
that they should win the next competition coming up. They were going to get
overloaded. Unfortunately, Grumman was really on a roll there. They had done
a reorganization, put good guys in charge of all the forward looking programs
and had a good crew. Grumman ended up by foxing the Navy by not bidding as
a prime but as a sub-contractor to Bendix. Bendix won the Eagle competition
and Grumman was heavily involved in the effort.
The Eagle program went
along fairly well, well enough that the airplane part of it got started on
schedule in 1959. That was a pretty tough competition. It was a controversial
airplane in the sense it was such a low performance airplane. It was to be
a subsonic airplane, two turbo fan engines, two place side by side and as
I said with this five foot radar dish in the nose. The air frame part of
the game was really not too difficult a technical job. It would have been
obviously a lot easier than it would have been doing a supersonic type of
airplane. That competition then ended with Douglas winning it with a very
straightforward design with six missiles mounted on the wings, three on each
side, externally. Straightforward airplane.
One of the interesting
things out of the competition was a Vought entry which had predicted extremely
low missile drag as mounted on their airplane based on wind tunnel tests.
What it had amounted to in effect was that they ended up with positive interference
drag. Usually you can take the drag of a pylon, the drag of a missile, put
the two together and you add another hunk of drag to it for interference.
In the case of Vought they were showing that the combination of a pylon and
the missiles was less than the total of the two individual drags. Our aero
guys didn't believe that and it became a big issue. If they had been right
they would have been a more serious contender for getting the award than
they were. With our performance estimate they were definitely in second place.
Subsequent to the award
to Douglas, Vought turned all their drag data over to Douglas. This was not
the first time that this type of thing had happened but it's worth mentioning
that in these competitions that the losing contractors if they have something
worthwhile in it will normally give it to their competitor in order to get
a better plane for the fleet. It's worth mentioning because every once in
a while there's a federal program or an OSD directive that we should do "technology
transfer" or try to pick the best items out of each airplane and so on. It
happens automatically if it's worth doing.
Unfortunately with the
Missileer, McNamara's arrival on the scene came along. The outgoing administration
did not want to let a full development contract until the incoming administration
approved the program. So we kept Douglas on a low level engineering effort
probably under $1 million to do some preliminary engineering but then left
the decision whether to go ahead in May to the incoming administration. McNamara's
crew, as you know, then said the Navy has a new airplane started, the Air
Force has a new fighter started called TFX in the Air Force terminology.
They're going to fight the same enemy, why don't they do it with one airplane?
And the general impression that the working level guys had was the conversation
must have been almost that casual, if they're going to fight the same enemy
they can do it with one airplane. It later developed into a God awful mess.
The whole TFX story has had books written about it.
As a sidelight I guess
I read three of the books and in no case did the authors of those books talk
to me. Never. And most of them are wrong. All of them are wrong. Parts of
the books are correct but the inferences drawn as to why we did things and
why we didn't do things are all wrong. The first one was supposed to be McNamara
proving to the services that he could wear them down. The military was fighting
civilian rule and that wasn't the case at all. The Air Force and Navy were
really only doing a technical job that McNamara's crew was screwing up and
it was just awful.
RAUSA:
And this hadn't happen before where you had the DOD staff intermingling into
the development of an aircraft?
SPANGENBERG:
No. Up to that time in my understanding, in my experience what happened,
the OSD staff might question you on something but they'd accept the reasoning
or the technical input from the services. McNamara's crew just didn't believe
us and they had a bunch of honest to God incompetents. But the outcome of
that mess was the McNamara group cancelled the airplane, the Eagle continued
into early 1960 and it finally got cancelled I think in May of 1960. So thus
ended the Eagle Missileer concept but it set the stage then for the things
that came later, the TFX.
I think we ought to skip
that then and go back to these other airplanes that were involved because
they were a series and they kind of set the stage of the way we procured
airplanes in the future. We got into fixed price contracting at about that
time. What had really been happening in the development field is that the
Navy had the A3J which became the RA5C, the E-2 and the A-6, all under development
at the same time using cost plus contracts. The overruns every year on each
of those programs was enough that the Navy kept having to cancel out the
little tiny R&D programs that are the seed for the future and it was
just raising havoc with the whole R&D development because of the overruns
on the major weapon systems. In part we thought we had solved the problem
before when we went to the FIRM plan, which stood for Fleet Introduction
of Replacement Models some years before. We had said then that we will only
fund airplanes with R&D funds through the mockup stage and after that
it would be production funds. This is starting to sound contradictory so
I'm screwed up somewhere on the things that happened. Actually we did do
that and then a whole series of airplanes that we did in that 1950 time period
were only funded R&D-wise at very small levels and everything else was
done on production funding where the big money was and where then you had
more flexibility to operate. As an example, the F-4 got started with perhaps
no R&D funding. We did it on the tail end of the F3H contract and so
on. The A3J, I think something like $4 million was all the R&D money
that was involved. Anyway, that allowed the Navy to start too many airplanes
by getting this windfall when they did the switch over. Instead of having
to fund a whole program out of R&D we only had to fund the beginning
of it. It allowed us to start in one year more airplanes than we could have
under the old rules.
Money was becoming more
important in reaching decision phases in our competitions. Up to sometime
in the fifties we scarcely mentioned money when we did a design competition.
The concept had all been approved with paper studies within the Navy and
reenforced by airplane studies by the contractors that gave you a second check
on what the designers in the bureau were saying could be done. And then when
we got an item in the budget we would do a competition, but we wouldn't fund
anything until we really had congressional approval to get the program started.
McNamara's crew changed all of that and the change is still causing problems
today. Now you must get a program well started before you have any approval
on the Hill whether you're going to be allowed to continue it.
The Marines then came
up with another requirement, this time for a 4,000 pound payload helicopter
which eventually became the CH-46. At the time Sikorsky had in production
what we called the HSS-2 when it started and it became the SH-3 in a model
designation change. Two turbo props powering the helicopter. It was an ideal
size for this 4,000 lb. payload helicopter. The Marines were working closely
with Sikorsky, put a rear ramp on the airplane and it was a shoo-in really,
that's the way we were going to go. We ended up having a competition, however,
and at the time Vertol was flying a civil version of a design that really
started back with the HUP. Vertol's design commercially was called the V-107.
They were demonstrating it, trying to sell it to airlines for mid-city airport
to the outlying airport kind of transportation or inner city of Washington
to Baltimore. In the civil version it was probably about a twenty place,
16-20 place design. Pretty nice flying machine. They took everybody for rides
in it. They entered the competition basically against the Sikorsky design.
Sikorsky should have won hands down but Vertol ended up by doing an excellent
technical job. They too had gotten the Marines up there to have informal
mockups and so on all before the competition was held. They ended up with
an excellent technical design and then for the cost they ended up bidding
fixed price -- we were going to buy 200 helicopters. They gave us a fixed
price bid based on the fact that at the time they sold us 200 they would
sell 300 on the outside. So their average price then was down the learning
curve and you averaged out 500 helicopter production and the Navy then got
the benefit of an average price for 500 and they quoted it for the Navy's
200 which put it well under the Sikorsky price. And with a better technical
evaluation all through we ended up buying the CH-46.
Sikorsky got very unhappy
and though we didn't know it at the time they went to Deputy Secretary of
Defense Gilpatric and told him that unless they won the next one they were
going to be out of business. They just didn't have enough business to continue,
applying "industrial statesmanship" pressure before the next event. The next
event was the CH-53 and that competition was for a payload of 8,000 pounds,
twice the 4,000 pound design payload of the 46 and lo and behold we expected
Vertol to win that one based on their Chinook experience. They had the Chinook
in production by that time, for the Army. It was a little too tall to fit
on the carrier and so they had to do something about reducing its height
but we thought that they could save the entire rotor system and transmission,
engines and so on and win that one. Well, Sikorsky came along, did a lot
better job on the proposal than Vertol did and underbid them, again on a fixed
price basis but we were only scheduled to buy 100 of those so Sikorsky bid
fixed price on the basis of 100 helicopters.
RAUSA:
How did you feel about that?
SPANGENBERG:
That was fine. It was good for the Navy. The price was not so low but what
we thought that Sikorsky might lose money on it but they wouldn't lose a
lot and the chances were good that they would sell that design to other people
and they ended up doing that. It became the Jolly Green Giant for the Air
Force and we ended up buying a good deal more than 100 of the helicopters
too. And it became the base for the CH-53D and CH-53E. It was an excellent
program.
As I said we finished
the competition. We ended up at the end of the road with Sikorsky winning
this one and I remember still we were sitting down with -- I think Col. Holloway,
program manager for the project, and myself and two of the other people that
had been involved in getting the final series of briefings and approvals
underway. We were outside of the Secretary of the Navy's office. You usually
made an announcement on a Friday afternoon late enough that the stock market
had closed. That had been mandated beforehand. We were looking through the
papers, the file of folders and lo and behold there was a note in there:
"Notify Gilpatric before you make a decision." I didn't know about it at
that time. Col. Holloway knew about it. It was his note. And he said, "What
have I done?" Here we've notified everybody, an announcement is going out
and we haven't told Gilpatric, then as I said the Deputy Secretary of Defense.
Holloway called the Chief, the Chief called and received authority to continue.
TAPE 10 of 16, SIDE B
. . .so everything worked
out all right. God knows what would have happened if the answer had been
wrong from the Gilpatric angle. The technical part of the CH-53, it actually
used the same rotor geometry that had been on the HR2S, the old twin R2800
engined design -- previously our biggest helicopter. Added one blade to it,
went from five to six blades on the CH-53 and they also had more or less
that same rotor system on a development that they were selling to the French
at the time. I forget the designation but it all tied in. Sikorsky always
seemed to do a good job of taking previous models and using pieces of them
to put together the next program, saved on the development effort and they
were using things they had a lot of experience with so usually the results
were pretty good.
The next thing that came
along and again was an awful mess and one that has lots of lessons in it
was something called the Tri-Service Transport. It shows up in the Navy starts
as the X-22 because that was the outgrowth of it for us. But the important
part really was that which came before. The VTOL issue which since the start
of the helicopters has had over enthusiastic advocates always claiming "now
is the time" that we can do a full production go ahead with something that
will replace, in this case it turned out to be large transports. The feeling
had been bruited about in the technical press, and is the kind of thing that
still happens. A VTOL advocate will write an article on now is the time for
the Navy to switch over to VTOL. In this case, it was a "blue ribbon commission."
Unfortunately, the whole effort was classified Secret and the overclassification
as usual screwed things up quite a bit. The technical committee ended up
with about six technical subcommittee reports. All of these were well done
and technically sound. The summary report was written by the chairman of
the committee who was Prof. Courtland Perkins, then head of the aero department
at Princeton. Cort is a real nice guy whom I consider a friend, but he's
too often overenthusiastic. His Summary Report largely disregarded the subcommittee
reports. It said "now is the time." The state of the art is such that we
can build a transport-type VTOL that will meet the requirements of all the
military services. The Tri-Service Transport was born. The Tri-Service Transport
then was just as impossible as TFX was. We were a little ahead of TFX time-wise
I think. But it was the same kind of a mess. The Marines had their requirement
which was basically the CH-53D requirement as far as number of troops and
so on for the fifty mile radius but they wanted it done at 300 knots, about
where we are today with the V-22, over thirty years later.
The Army requirement,
I can't remember exactly what it was but it was a medium range distance requirement
coupled with a heavy lift requirement, probably well beyond the Marine lift
requirement. The Air Force came up with an air-sea rescue mission that they
would go 750 miles to pick up a pilot that had ditched.
RAUSA:
750?
SPANGENBERG:
Right, radius. Again we had this mishmash of requirements. You knew it couldn't
be met by any single airplane. When I was thinking of that -- you remember
I showed you the source selection briefing and there was a picture of an admiral
throwing a dart at a board. You might want to look at these cartoons. These
particular sketches were given to me after the competition. They were done
at North American who ended up getting no award in the competition. It should
give you a feel for the things that were going on at the time. They actually
put it out as a pamphlet and it was widely distributed in black and white
form. Why I got these I don't know. I guess they thought I deserved them.[ed: in theory, the complete set will be available in the future.
For now, some of the cartoons may be found in the A-2 viewgraphs.]
[laughter]
RAUSA:
Who drew these?
SPANGENBERG:
They were done at North American.
RAUSA:
[looking at sketches] I remember that.
SPANGENBERG:
[showing cartoons] That was the evaluation and they're looking at the North
American entry of the Tri-Service Transport. This next one shows the folding
sequence where the tractor pulled it out and it collapses down. The weight
problems are solved. The weight guys at North American were all somewhat
overweight themselves. I can't remember their names. I told you we would
get off with a full load. [laughter] The payload comes out the bottom. [laughter].
I've heard of close support but this is ridiculous. This ain't how it worked
out on the simulator. [laughter]
RAUSA:
These are funny. Weights and measures. 17 times 30 times 50.
SPANGENBERG:
The meaning of that is the requirement was for the VTOL to operate aboard
the LPH-2 for the Marines which was an older converted small carrier. It
has a seventeen foot height hangar deck-type. You couldn't be more than thirty
feet wide and fifty feet long. This really should have been twenty-seven
and a half passing in the hangar deck. An impossible requirement to meet.
RAUSA:
These are great.
SPANGENBERG:
The flight handbook doesn't mention it going down. Ah, that's better going
up.
RAUSA:
That's the best one, that last one. Those are precious. Were they ever published
anywhere to your knowledge?
SPANGENBERG:
As far as I know, as I said at the time of the competition they were put
out in 8 1/2x11 black and white copies.
RAUSA:
Those are great. Don't ever lose those.
SPANGENBERG:
But what do I do with them?
RAUSA:
If you like I can take them and have them copied on our Xerox machine. We
have a zoom thing on it |
