I find it near impossible that we retired the SR-71 and the Shuttle both without having operational ready replacement craft. Both of those platforms
were late 50's (SR) and Mid 70's (Shuttle) technology.
I think that it is entirely plausible that the space shuttle was scrapped due to its massive cost and the fact that it’s cheaper to user rockets to
put satellites in orbit and resupply the ISS. A secret replacement for the space shuttle would be fantastically difficult to keep quite, what with
all the smoke and noise! Besides, the commercialisation of space shows better ways to do things – had Virgin Galactic been a NASA programme it
would have already cost quadrillions, employ thousands and be behind schedule by years.
The SR-71 was also vastly expensive to maintain with attrition taking a toll and designed for a different world. The job of the SR-71 is better done
by satellites and UAVs although rumours of Aurora persist.
I do believe that the military have quite a few tricks up their sleeves and if the *hit hit the fan I imagine many would be revealed, but only if
necessary. Besides, over the last decade of conflict in Iraq and Afghanistan many new technologies have reached maturity as part of normal evolution.
