At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic). An F/A-18 Hornet creating a vapor cone at transonic speed just before reaching the speed of sound. The local speed of sound, and hence the Mach number, depends on the temperature of the surrounding gas.
Mach 10 or variation, may refer to: Mach number for ten times the speed of sound Hypersonic speed of 10 times the speed of sound; Mach 10 Training Systems, a coaching consultancy of James McCallum (cyclist) "Mach 10" (song), a 2007 song by Dub Pistols off the album Speakers and Tweeters; MachTen, a Unix-like operating system based on BSD and ...
Flow in this regime is still Mach number dependent. Simulations start to depend on the use of a constant-temperature wall, rather than the adiabatic wall typically used at lower speeds. The lower border of this region is around Mach 5, where ramjets become inefficient, and the upper border around Mach 10–12. [citation needed]

Project Mayhem, the Air Force's secret new hypersonic bomber, is underway. Development on the bomber, which travels at Mach 10, just took a big step forward.
Oreshnik (Russian: Орешник, lit. 'Hazel tree'), [2] is a Russian intermediate-range ballistic missile (IRBM) characterized by its reported speed exceeding Mach 10 (12,300 km/h; 7,610 mph; 3.40 km/s), according to the Ukrainian military.
