I still don't believe that they retired the SR-71 due to fuel costs. I mean, of course a plane whose engines take up most of the craft's volume is going to use a lot of fuel. Those things went faster than a bullet - just imagine them given weapons. Actually nevermind, they might have outrun their payload and gotten hit by it.
But let's think about something: The F-117 and SR-71 were designed 30 years ago. Makes you wonder what they're designing right now, considering how stealth technology is still super-classified.
I beleive they did arm an SR-71 with nuclear missles and named it an A-12. Cruise missles were invented however so the prototypes were scrapped.
You've crossed several different planes into one, let me try to straighten you out a bit.
The A-12 was the CIA version of the Blackbird before the Air Force got it (or a version of) and named it SR-71. According to unconfirmed information, since both planes are still partially classified, the A-12 was a better spyplane since the camera could be tilted, but the SR-71 had a higher top speed.
There was a prototype interceptor version called YF-12, which would've carried the AIM-47 missile which is what the AIM-54 Phoenix missile was derrived from. Interesting factoid, the YF-12A prototype that set the absolute speed record in 1965 is stored with the trophy in the R&D hanger at the National Museum of the USAF at WPAFB, Dayton, OH.
The AIM-47 was originally intended to be a nuclear missile, but a conventional warhead was decided on. There was a plane that carried a nuclear air-to-air missile, the F-106 Delta Dart.
