The X-51 Waverider’s 2013 hypersonic flight represented a milestone in military aviation, reaching Mach 5.1 using a scramjet ...

The British government said earlier this month that scientists had completed testing on an air-breathing engine for an in-development "cutting-edge" hypersonic cruise missile. The scientists ...

What's wanted if you're building a hypersonic cruise missile is an air-breathing engine that can continually power the vehicle along. This gives it a much greater range than a rocket or hypersonic ...

The North American X-15 was an experimental Air Force and NASA Hypersonic Rocket powered aircraft that was used to ...

and hypersonic cruise missiles, which are powered by high-speed, air-breathing engines during flight. As former Vice Chairman of the Joint Chiefs of Staff and former Commander of U.S. Strategic ...

Mach 5 is the threshold for hypersonic speed, which is five times the speed of sound. The tests demonstrated the performance of “the high-speed air-breathing engine — enabling greater ranges ...

they can also avoid most air defenses. However, America is working with Japan to develop defensive systems that can target and take out hypersonic missiles. Unfortunately, those missile defense ...

Safety concerns, particularly around the extreme heat and pressure generated during hypersonic flight, would need to be addressed before it becomes viable for commercial use. Current air traffic ...

At hypersonic speeds — above Mach 5, or more than 5 times the speed of sound (3,836 mph or 6,174 kilometers per hour) — the flow of air around a vehicle's surface becomes complex and bumpy.

Hypersonic speed is defined as faster than five times the speed of sound, or greater than Mach 5. When a vehicle is flying that fast, the air moving around a flying object will chemically decompose.
