Seventh generation fighters are being designed around a simple, unsettling premise: the human body is becoming the limiting factor in air combat. As engineers push toward hypersonic speeds, ...

India’s scramjet success proves hypersonic strength, but turbine complexity keeps fighter engines a tough challenge.

"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 ...

Combining the technologies could improve efficiency enough to make hypersonic projectiles much more affordable.

Air dominance is becoming harder to achieve as battlefields extend upward and outward, blurring the line between atmosphere ...
