The U.S. is racing to develop hypersonic weapons to counter China and Russia, but delays, limited testing and shifting ...

Hydrogen powered hypersonic flight is moving from speculative concept to detailed engineering plan, with aerospace startups and research partners sketching out aircraft that could cross continents in ...

Could a hypersonic vehicle take flight this weekend in the deserts of Southeastern California? It appears Stratolaunch, an aerospace company based in Mojave about 100 miles north of Los Angeles, is ...

The U.S. is expanding hypersonic testing through a Rocket Lab contract, accelerating development of high-speed military ...

Add Yahoo as a preferred source to see more of our stories on Google. Hypersonica's first hypersonic test flight in Norway pushed its missile prototype to more than Mach 6 and a range of more than 300 ...

Hypersonic aircraft promise to compress distance and time in ways that make even the fastest supersonic jets look dated, yet the United States Air Force is discovering that flying at several times the ...

Stratolaunch built and operates the world’s largest airplane by wingspan. It is the twin-fuselage Roc, which serves as an air-launch platform for reusable hypersonic vehicles. Their primary focus is ...

Drone threats and systems used to defeat them could be at an “inflection point,” Brett Velicovich, who co-founded the startup ...

Hypersonic flight has made great strides in recent years, but programs have run up against a bottleneck when it comes to propulsion at the requisite velocities. Essentially, solutions have broken down ...

Hypersonic flight may seem like the biggest shove to the envelope since the sound barrier was broken in 1947 and rotating detonation may look like a quantum leap in propulsion, but combining the two ...

Ursa Major said its Hadley liquid rocket engine completed 10 flights, including multiple hypersonic missions with ...

Hypersonic vehicles — aircraft that can reach speeds of Mach 5 and beyond — are subject to extreme conditions while they are in flight, requiring strong yet aerodynamic materials to keep them both in ...
