Hypersonic speed - Wikipedia
In aerodynamics, a hypersonic speed is one that exceeds five times the speed of sound, often stated as starting at speeds of Mach 5 and above. [1]
Hypersonic weapon - Wikipedia
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. Typical Low Earth Orbit atmospheric re-entry speed is Mach 25. [2] .
