The United States Air Force is building a fleet of uncrewed combat drones designed to fly alongside its most advanced manned ...

Shaped much like a miniature NASA space shuttle, Stratolaunch's uncrewed, rocket-propelled Talon-A2 aircraft detached in midair from the world's largest plane in March and zoomed up to dizzying speeds ...

"Hypersonic" refers to speeds over Mach 5, or five times the speed of sound. That's approximately 3,800 miles per hour, a pace that could take you all the way around the equator in less time than it ...

Hypersonic flight could one day make long-haul travel as quick as a short movie. Researchers are testing how turbulence behaves at extreme speeds, a critical hurdle for designing these aircraft. Their ...

GE and Lockheed ground tested a new air-breathing hypersonic jet engine capable of powering missiles to speeds well in excess of Mach 5 in a smaller, cheaper, lighter, and more efficient package than ...
