If you were going Mach 20 it would have to be an orbital platform, anything else would probably be too heavy with the amount of heat shielding it would need.

ya that does sound kinda farfetchd warp drive really this ain't star trek. come on man think of something that actually sounds reasonable for the near future.
Visual camouflage, meta materials than bend then re- broadcast microwave radiation in computer controlled bursts to fool the bi-static radars that the air is empty, oh and... lets see, a bi-static targeting capability using UAVs to saturate the air and the weapons carrier only using passive means to get pin point targeting radar data.
Lets for this exercise assume that 'white noise' type signals are used and are at the moment totally undetectable to an enemy as they are all so natural and so random.
I wonder how this will compare with Skylon or Lapcat 2 for commercial flights with there engines

If there was a mach 20 ISR vehicle I don't think it would go from 0 mph to 15,500 mph (Mach 20) in a short enough time for a human to worry about acceleration forces. A Shuttle launch goes from zero to 18,000 mph (Mach 23) in 8 minutes straight up and I don't think they felt any more than 5 G's.
