A lot of the questions on this thread can easily be answered by reading "Skunkworks" by Ben Rich, hell the man did build the Blackbird afterall.

In the book he goes into detail regarding the development of successful prototype tactical bomber and interceptor versions of the Blackbird. For the bomber they just dropped a 1 ton steel penetrator. 2000 lbs of steel at Mach 3 packs a hell of a punch. Lockheed also developed a look-down shoot-down radar system and from 80k+ ft successfully knocked out drones as low as 1,500 ft. Hell they even had plans to use it as a space launch platform to carry ICBM's up to 60k ft. A lot of people know this plane was cool, but not many truly grasp how friggin badbutt it truly was, especially for its time.

I am, shall we say, HIGHLY dubious of the claimed Mach 6 speed of the Blackbird. If you do some basic compressible flow calcs you'll see that for the Blackbird to not have its wings sticking through its sonic cone (leading to horrible control problems) its top speed must be slightly south of Mach 4. Ramjets engines are pushing their efficiency limits near Mach 4 as well, so Mach 6 seems pretty unlikely. Its rated at Mach 3+, I've heard public accounts of Mach 3.3, and anecdotal accounts of 3.5 . If I were to guess its top speed is probably somehwere around 3.6-3.7 . Still not to shabby for a 40 year old girl. Hey maybe that Mach 6 number was one of the missiles fired from the interceptor prototypes? Awesome thread though, glad to see so many bird fans.

That thing sounds like a better idea than the Valkery, although the valkery was pretty cool with the big ole thruster engines and the deltas
