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

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.

Hypersonic flight is generally defined as speeds at or beyond Mach 5. However, unlike what happens as the aircraft approaches Mach 1, there are no distinctive changes in the flow characteristics as an …

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 …

Hypersonic vehicles can reach speeds exceeding 4,000 miles per hour—fast enough to reach Baltimore from Washington in about 30 seconds—and aggressors equipped with hypersonic missiles can …
