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

Feb 26, 2026 · What Makes a Weapon Hypersonic? The term "hypersonic" refers to speeds exceeding Mach 5 -- five times the speed of sound. At sea level, that translates to approximately 3,836 miles …

Hypersonic vehicles often feature blended bodies with tightly integrated propulsion systems, in stark contrast to the separate airframe and engine architectures of subsonic and supersonic aircraft.

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 …

Mar 13, 2026 · In the field of aerodynamics, hypersonics is generally associated with flight through an atmosphere at speeds in excess of Mach 5, i.e. five times the local speed of sound.

Hypersonic flight involves traveling at speeds greater than Mach 5, revolutionizing air travel and defense with rapid, high-altitude capabilities.
