Hypersonic flight is flight through the atmosphere below altitudes of about 90 km (56 mi) at speeds greater than Mach 5, a speed where dissociation of air begins to become significant and high heat loads exist. Speeds over Mach 25 have been achieved below the thermosphere as of 2020. [citation needed]

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]
The Lockheed Martin SR-72, colloquially referred to as "Son of Blackbird", [1] is an American hypersonic UAV concept intended for intelligence, surveillance and reconnaissance (ISR) proposed privately in 2013 by Lockheed Martin as a successor to the retired Lockheed SR-71 Blackbird. In 2018, company executives said an SR-72 test vehicle could ...
The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 (3,300 mph; 5,300 km/h) and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010.
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA 's Hyper-X program developed in the late 1990s. [1] It set several airspeed records for jet aircraft.
5 sty 2024 · NASA made aviation history with the first and second successful flights of a scramjet-powered airplane at hypersonic speeds – speeds greater than Mach 5 or five times the speed of sound.
7 gru 2021 · Our researchers are discovering innovative ways to use aircraft to develop new space capabilities and test space technologies in a relevant environment. Hypersonics research is important both for aeronautics and space research to enable extremely fast travel on Earth as well as for future space exploration.
