Nasa scientists theorised in 1978 that it could enable sustained hypersonic cruise from Mach 6 to 16 but the concept faced scepticism due to extreme technical hurdles.

A plane is supersonic if it moves faster than the speed of sound in air, which is around 343 meters per second (767 miles per hour, 1235 kilometers per hour). That is what is considered Mach 1.

That’s why in 2022 the Pentagon launched the MACH-TB program to create low-cost options for testing ... The vehicle was air-launched over the Pacific Ocean by Stratolaunch’s Roc carrier plane—the ...
