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

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, …

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.

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 …

Apr 3, 2025 · NASA is working to enable routine, reusable, airbreathing hypersonic flight by conducting fundamental and applied research to enable a broad spectrum of hypersonic systems and missions.

Jan 9, 2026 · Learning from an anomaly during the first BOLT-1A flight, the successful BOLT-1B follow-on flight experiment collected hundreds of critical measurements, providing data to advance …

Nov 13, 2025 · The fast and the curious: The breakthrough research bringing hypersonic flight closer to reality New Mach 6 turbulence research has validated a long-debated aerodynamic theory, offering …

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 …

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 …

6 days ago · Russia fired its hypersonic Oreshnik missile overnight at Ukraine, Moscow confirmed on Friday, striking a city barely miles away from the Ukrainian border with Poland, at a time when efforts …
