Hypersonic cruise missiles, which are powered by scramjets, are limited to below 30 km (19 mi); [c] hypersonic glide vehicles can travel higher. Hypersonic vehicles are much slower than ballistic (i.e. sub-orbital or fractional orbital) missiles, because they travel in the atmosphere, and ballistic missiles travel in the vacuum above the ...
A hypersonic weapon is a weapon capable of travelling at hypersonic speed, defined as above Mach 5, or above 5 times the speed of sound. [ 1 ] Below Mach 1, weapons would be characterized as subsonic , and above Mach 1, as supersonic .
Simulation of hypersonic speed (Mach 5) While the definition of hypersonic flow can be quite vague and is generally debatable (especially due to the absence of discontinuity between supersonic and hypersonic flows), a hypersonic flow may be characterized by certain physical phenomena that can no longer be analytically discounted as in supersonic flow.
Reusable human-rated hypersonic flight is not new. In the 1960s, the X-15 completed over 120 flights above Mach 5 at altitudes surpassing those of typical commercial aircraft. From the 1980s ...

The Saenger was a highly aerodynamic hypersonic aircraft, similar in size to a conventional Boeing 747 airliner, and capable of taking off like conventional aircraft. [4] As a conventional aircraft, it was projected to have been capable of cruising speeds of up to Mach 4.4 over a range of 11,000 kilometers while carrying around 230 passengers; this was more than double the speed, range, and ...
The Hypersonic Air-breathing Weapon Concept, or HAWC, is a joint project between the U.S. Air Force and the Defense Advanced Research Projects Agency (DARPA) to develop and test air-launched ...
