DARPA developing a hypersonic defense interceptor

Aerojet Rocketdyne is working on technology to help knock high-speed maneuverable vehicles out of the sky, under a new contract from the U.S. Defense Advanced Research Projects Agency (DARPA).

Since 2018, DARPA has been developing a “hypersonic defense interceptor” system called Glide Breaker, which is designed to intercept threatening vehicles moving at hypersonic speeds (meaning, at least five times faster than the speed of sound) in Earth’s upper atmosphere.

Aerojet Rocketdyne will develop “enabling technologies” for Glide Breaker under the newly announced contract, which is worth up to $19.6 million.

“Advancing hypersonic technology is a national security imperative,” Eileen Drake, Aerojet Rocketdyne CEO and president, said in a statement. “Our team is proud to apply our decades of experience developing hypersonic and missile propulsion technologies to the Glide Breaker program.”

Based on the images available on DARPA’s Glide Breaker program page, it appears that the new tech will involve launching missiles to hit hypersonic vehicles in flight. No other information about the program, however, is available on the web page.

Aerojet Rocketdyne pointed to other contracts it has with DARPA to show its expertise in hypersonic flight, using either solid-fuel propulsion or engines that are “air-breathing” (typically, gas turbine engines).
