Glide Breaker

Defense Advanced Research Projects Agency (DARPA) is seeking innovative proposals to conduct wind tunnel and flight testing of jet interaction effects for Phase 2 of the Glide Breaker program. The overall goal of Glide Breaker is to advance the United States’ ability to counter emerging hypersonic threats. Phase 1 of the program focused on developing and demonstrating a Divert and Attitude Control System (DACS) that enables a kill vehicle to intercept hypersonic weapon threats during their glide phase.

Phase 2 will focus on quantifying aerodynamic jet interaction effects that result from DACS plumes and hypersonic air flows around an interceptor kill vehicle. The Glide Breaker Phase 2 Broad Agency Announcement (BAA) can be found at this link.

«Glide Breaker Phase 1 developed the propulsion technology necessary to achieve hit-to-kill against highly-maneuverable hypersonic threats. Phase 2 of the Glide Breaker program will develop the technical understanding of jet interactions necessary to enable design of propulsion control systems for a future operational glide-phase interceptor kill vehicle. Phases 1 and 2 together fill the technology gaps necessary for the U.S. to develop a robust defense against hypersonic threats», said Major Nathan Greiner, program manager in DARPA’s Tactical Technology Office.

Aerojet Rocketdyne has been awarded a contract worth up to $19.6 million by the Defense Advanced Research Projects Agency (DARPA) to develop enabling technologies for an advanced hypersonic defense interceptor known as Glide Breaker.

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

According to DARPA, the Glide Breaker program intends to advance the United States’ means to counter hypersonic vehicles. The effort aims to develop and demonstrate a technology that is critical for enabling an advanced interceptor capable of engaging maneuvering hypersonic threats in the upper atmosphere.

Aerojet Rocketdyne supplies both solid-fueled and air-breathing propulsion systems for hypersonic flight. The company provided both types of systems for the joint Air Force-DARPA-NASA X-51A WaveRider, which completed the first practical hypersonic flight of a hydrocarbon-fueled and -cooled scramjet-powered vehicle. More recently, the company successfully completed a series of subscale propulsion-system test firings as part of DARPA’s Operational Fires (OpFires) program, which is an effort to develop a ground-launched hypersonic missile for tactical use.
