So why do I love it? Fast? Check. Good looking? Yup. Cold war-era built to a slim list of mission parameters? Affirmative.
So far so good. What about those early tests? First flight, landing gear wouldn't retract and then caught fire on touchdown. The first time it went supersonic it flexed enough to peel a lot of its paint off. The first time it went Mach 3, it came back with 2 feet of the leading edge of the wing missing and was subsequently limited to Mach 2.5. The second Valkyrie, now that they had learned more about the construction processes and design addressed many of those issues and also went Mach 3. Once the temperatures had settled on that one, it was determined that if it had been flying with a full fuel load, it would have been able to sustain Mach 3 for 2.5 hours. Remember this thing first flew when The Animals and Roy Orbison were topping the charts in late summer 1964. No CAD, no digital flight control, no engine management computers. That YF-12A below it was mostly titanium alloy, 93% of its structural weight. Since we didn't have THAT much titanium, the Valkyrie was largely a stainless steel honeycomb with titanium on select portions where it would get the hottest. We had never flown a half million pound airplane over 2,000 mph before....until we did.
The political environment surrounding it was pretty complicated, but the short version was this thing was first flying when we really started to get good at just lobbing nukes at people on top of a missile without bothering with all this. Russian surface to air missile technology was advancing quickly, too. The program was shifted from military goals to research goals fairly early on. It was also a fairly expensive program at around $1.48 Billion. How many planes did we get for that? Just two. Wanna see some funny math? That worked out to almost $6 million per flight hour achieved. Steve Austin, eat your heart out.
Oh and then of course the infamous crash where NASA Pilot Joe Walker, flying in formation with Number #2 during a photo shoot, accidentally collided with it, partly due to visibility limitations and partly the vorticies from the Valkyrie's wingtips. Walker's F-104 exploded and he was killed, and the crippled bomber crashed into the desert. Pilot Al White managed to eject, but co-pilot Carl Cross did not.
Even though it never carried so much as a bomb sight, it taught us a ton about speed and heat, and sonic booms and compression lift, aerospace materials, construction and design. Data was used for the American SST project of the mid 60s and later the B-1.
And I finally got to see it.
So what else was cool on this end of the hangar? Oh just stuff like a Titan IV B rocket capable of lifting 23.9 tons into low earth orbit. In 1997 one of these launched NASA’s Cassini-Huygens spacecraft to study Saturn and Titan. What else is there, a spy satellite? Gambit 1 KH-7. Flown from 1963 to 1967. Capable of resolving a 23- foot object from orbit and the first satellite to feature stereo cameras. 3000 feet of film, which meant that yes, the film had to be dropped in a return capsule and caught in midair. What's that other charred capsule back there? Only the Apollo 15 command module.
The piece of moon rock I saw in Edmonton came back in this. The connections keep coming. Anyone know why the USAF wanted this particular CM in their museum?
That whole thing is a spy satellite. From 1971-1986, 19 missions using these Hexagon KH-9s imaged 877 million square miles. This would do wide area search with similar resoluton, and then Gambits would focus on potential cold war threats. This behemoth carried 320,000 feet of film, ~60 miles of it and 4 or 5 film return vehicles.
A couple of the lifting body aircraft that helped further our knowledge of reentry for space planes. Funny looking, but these went supersonic also. Col when you remember the first lifting body in the program was a glider towed behind a car. Yeah, a 1963 Pontiac Catalina convertible.
Fisher P-75A Eagle. Does the Fisher name sound familiar? It might if you're a GM fan. The Fisher Body Division of GM developed this plane to fill an urgent need for an interceptor early in WWII. At one point there was an order for 2500 of them, but in the end we had the P-47 and P-51 and just didn't need it. The engine was in the back with long driveshafts turning counter rotating props. That engine was essentially two Allison V1710's bolted together to make the V3420, a 3,420 cubic inch double V 24.
Can't seem to get away from this thing, it's rather conspicuous. The engine on the cart is the YJ93, produced only for this and the unrealized XF-108 Rapier Mach 3 interceptor project. Almost 30k pounds of thrust, and the Valkyrie has 6 of them. Oh, and a geeky moment, it was based on an engine that was essentially a larger version of the J79 that powered the F-104 Starfighter, that small plane crush of mine you've seen before which happens to be the plane that crashed into the other Valkyrie. These are the things I find interesting.
The X-3 never really did anything cool, it never broke the sound barrier because it didn't get the engines it needed. But it tested short wings that eventually found use in the Starfighter, so that's good. It's pointy though.
This is the last building. There's more cool stuff coming including Air Force One.
