An aircraft running on hydrogen that races through the upper atmosphere at speeds exceeding twelve times the speed of sound might seem like a fantasy reserved exclusively for science fiction. That, ...

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 pursuit of ...

The race to field reusable hypersonic aircraft got a whole lot hotter last month, with GE Aerospace announcing a breakthrough in high-speed jet engine design that could potentially allow conventional.

Lockheed Martin's Skunk Works has confirmed that it is developing the SR-72 spy plane. The successor to the SR-71 Blackbird, which was capable of Mach 3.5, the SR-72 will be a hypersonic unmanned ...

Despite the U.S. Defense Department’s near-term emphasis on the test and development of rocket-boosted hypersonic glide weapons, most proponents of high-speed defense doctrine concur that mastery of ...

NASA has been officially recognized for setting the speed record for a jet-powered aircraft by Guinness World Records. NASA set the record in November during the third and final flight of the ...

NASA’s X-43A research vehicle screamed into the record books today, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered ...

At Mach 6, the SR-72 can cut across radar fields of view so quickly that establishing a continuous track becomes nearly impossible. The race to field reusable hypersonic aircraft got a whole lot ...
