Now they're proposing a Mach 4+ airliner.

There are a lot of challenges that come with a Mach 4 commercial aircraft that are not constraints for a military aircraft. Some that come to mind; Chapter 14 community noise certification, mutual inlet unstart, certifying the inlet control system, rotor burst, material allowables development, fuel availability (can’t use standard jet fuel), ozone depletion, 250 kt restriction on operations below 10,000 ft, taxi in and taxi out times, turnaround time issues due to the airframe temperature. The Breguet range equation would indicate that the MTOW of the AS3 would be exceptionally high.
