In aerodynamics, hypersonic speed refers to speeds much faster than the speed of sound, usually more than approximately Mach 5. [1][2] [3]

Jul 22, 2025 · The United States has actively pursued hypersonic weapons — maneuvering systems that can travel at speeds of Mach 5 and greater — since the early 2000s.

Hypersonic flight is generally defined as speeds at or beyond Mach 5. From an engineering perspective, hypersonics is best understood as a multidisciplinary regime in which fluid mechanics, …

We are developing game-changing hypersonic solutions to ensure our customers are always ready for what’s ahead. Traveling at Mach 5 (or a mile a second) and above is the new standard on the …

A NASA system designed to measure temperature and strain on high-speed vehicles is set to make its first flights at hypersonic speeds – greater than Mach 5, or five times the speed of sound – when …

Nov 14, 2025 · Hypersonic flight could one day make long-haul travel as quick as a short movie. Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing …

5 days ago · Two revolutionary aerospace technologies collide as GE Aerospace and Lockheed Martin team up to demonstrate a new liquid-fueled rotating-detonation ramjet (RDRJ) designed to close the …

Sep 27, 2023 · Hypersonic speed is five times the speed of sound. Scientists measure speeds this fast with a Mach number, named for Austrian physicist Ernst Mach. Sound has a speed of Mach 1 and …

Jan 9, 2026 · The intense barrage and the launch of the nuclear-capable Oreshnik missile came days after Ukraine and its allies reported major progress toward agreeing on how to defend the country …

Hypersonic vehicles are commonplace. There are many more of them than the supersonic aircraft discussed in the last chapter. Applications include missiles, launch vehicles and entry bodies. A huge …
