The X-15 had an ejection seat designed to operate at speeds up to Mach 4 (4,500 km/h; 2,800 mph) and/or 120,000 feet (37 km) (23 miles) altitude, although it was never used during the program. [12] In the event of ejection, the seat was designed to deploy fins, which were used until it reached a safer speed/altitude at which to deploy its main ...
The first manufactured object to achieve hypersonic flight was the two-stage Bumper rocket, consisting of a WAC Corporal second stage set on top of a V-2 first stage. In February 1949, at White Sands, the rocket reached a speed of 8,290 km/h (5,150 mph), or about Mach 6.7. [2]
So the regime of flight from Mcrit up to Mach 1.3 is called the transonic range. [citation needed] Northrop X-4 Bantam (Mach 0.9) — Supersonic [1.2–5) 921–3,836 mph (1,482–6,173 km/h; 412–1,715 m/s) The supersonic speed range is that range of speeds within which all of the airflow over an aircraft is supersonic (more than Mach 1).
The first two X-43A aircraft were intended for flight at approximately Mach 7, while the third was designed to operate at speeds greater than Mach 9.8 (10,700 km/h; 6,620 mph) at altitudes of 30,000 m (98,000 ft) or more.

Prior to the X-43A, the fastest recorded powered airplane flight, and still the record for the fastest manned powered airplane, was the North American X-15, rocket-powered airplane at Mach 6.7 or 7,274 km/h (4,520 mph) on 3 October 1967. [28]

The AGM-183 ARRW ("Air-Launched Rapid Response Weapon") is [5] a hypersonic air-to-ground ballistic missile planned for use by the United States Air Force.Developed by Lockheed Martin, the boost-glide vehicle is propelled to a maximum speed of more than Mach 5 [6] by a rocket motor before gliding toward its target.
