The AR-22 engine built by Aerojet Rocketdyne during hot-fire testing at NASA Stennis on June 27, 2018. The engine was built for Boeing as part of the U.S. Defense Advanced Research Projects Agency Experimental Spaceplane program. This new Boeing spaceplane, called Phantom Express, is intended to demonstrate a new paradigm for more routine, responsive and affordable space access. Photo courtesy of NASA.
