A possible contender to arm USAF’s next generation bomber has fired its scramjet engine for the first and completed a critical design review, according to a Boeing release. Air Force Research Lab’s Propulsion Directorate manages the X-51A WaveRider Scramjet Engine Demonstrator program for a consortium comprising USAF, DARPA, NASA, Boeing, and Pratt & Whitney Rocketdyne. The goal is to demonstrate hypersonic technology that Boeing’s Advanced Systems president, George Muellner, says could be used to deliver payloads to space as well as other atmospheric flight applications. He said earlier this year that it might well be adapted for the NGB.
The Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
