Not so hot, but check out those 0 to 500 times - 31 seconds. OK still not as good as an F-22, but then 0 to 1,000 in a minute and 2 seconds? :)

The limiting factor on all this, BTW is the G forces - a design limit of about 3 on the whole shuttle stack...

Of course that's nothing. The cone-shaped Sprint missile was powered by a two-stage solid-propellant rocket motor. The motor ignited after the missile had been ejected from its silo by gas pressure, and accelerated the Sprint with more than 100 g. Within seconds, the missile reached a speed of Mach 10+, (5,475 MPH) and the extreme thermodynamic heating demanded sophisticated ablative shielding (the nose was already glowing red-hot less than a second after launch). It's maximum range of 25 miles could be reached in 15 seconds!
