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

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 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 …

Apr 16, 2026 · Rocket Lab just signed a $190 million contract for 20 hypersonic test launches with a 100% success rate — 7 for 7 at Mach 5+. The tests support the Army's "Dark Eagle" — a Mach 5 …

Mar 26, 2026 · Hypersonic refers to any speed exceeding Mach 5, or five times the speed of sound. That translates to roughly 3,800 miles per hour at sea level.

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 …

Sep 8, 2025 · There are two main types of hypersonic weaponry: (1) hypersonic cruise missiles (HCMs) and (2) hypersonic glide vehicles (HGVs). Both systems are designed to impact targets from long …

6 days ago · FLASH seeks to integrate hypersonic boost-glide weapons into Mk 41 VLS cells, reducing reliance on Zumwalt-class platforms.

Today, new classes of hypersonic weapons capabilities are emerging throughout the world. This article provides a brief overview of the history, today’s state of the art, and the future potential for hypersonics.
