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

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 · The Hypersonic Technology (HT) Project organizes its work into distinct research topic areas. HT explores four key topics in hypersonics: system-level design, analysis, and validation; …

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.

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.

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 …

1 day ago · The biggest hurdle the Air Force has to overcome with hypersonic flight is the heat generated between the jet and the air at hypersonic speeds.

Dec 4, 2025 · Hypersonic speeds are difficult to validate unless an actual prototype takes to the skies, as ground facilities are incapable of reproducing the shock heating, turbulent flow, engine ignition, …

We’ve always felt the need for speed. And, after more than half a century, there continue to be breakthroughs in hypersonic aircraft and missile development. Hypersonic systems present a …

Hypersonics, defined as speeds exceeding Mach 5 (five times the speed of sound), represent one of the most significant advancements in modern military and aerospace technology.
