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

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.

3 days ago · Hypersonic weapons are in the spotlight. Here’s how they work, why they matter, and what current programs in Russia, China, India, and the US reveal about the technology and its limits.

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 …

Nov 29, 2025 · Hypersonic flight is no longer science fiction. In recent years, interest in aircraft capable of exceeding Mach 5 has surged, driven by strategic competition, defense challenges, and NASA’s …

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 …

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 …

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

The term "hypersonic" is now typically used just to refer to two types of weapons that are being developed through contemporary defense programs: hypersonic glide vehicles (HGVs) and …
