Blue Origin Debuts the American-made BE-3 Liquid Hydrogen Rocket Engine (with video)
"Blue Origin reached a key milestone in the development of the liquid-fueled BE-3 engine by successfully demonstrating deep throttle, full power, long-duration and reliable restart all in a single-test sequence. The BE-3 is the first completely new liquid hydrogen-fueled engine to be developed for production in the U.S. since the RS-68 more than a decade ago."
"NASA's Commercial Crew Program (CCP) has been working with the company on several aspects of the engine's development. The program supported testing of the BE-3 under the agency's Commercial Crew Development Round 2 (CCDev2) initiative and continues to offer technical support. NASA and Blue Origin also are partnered in review and tests of the company's Space Vehicle design."
