The subsonic test vehicle is the first flight-capable aircraft in the Quarterhorse line, with which Hermeus eventually hopes ...

Hermeus is breaking ground on a new engine and flight test facility HEAT will accelerate US hypersonic development, offering increased testing cadence for not only Hermeus, but the DoD and larger ...

Hypersonic missiles are classified as such if they're capable of reaching Mach 5-plus (3,836 mph). Several types have arisen, including hypersonic boost-glide vehicles, hypersonic cruise missiles ...

Hypersonic glide vehicles travel at speeds greater than Mach 5, or approximately 4,000 miles per hour, making them difficult to detect and intercept in time. They can also maneuver and vary ...

A Sandia Labs-built common hypersonic glide body launches from Pacific Missile Range Facility, Kauai, Hawaii, during a 2020 DOD flight experiment. In May 2024, an industry-manufactured version had ...

The United States has actively pursued the development of hypersonic weapons—maneuvering weapons that fly at speeds of at least Mach 5—as a part of its conventional prompt global strike ...

The term “hypersonic” describes any speed faster than five times that of sound, which is roughly 760 miles (1,220 kilometers) per hour at sea level, meaning these weapons can travel at least ...
