Blue Origin is best known for its own rocket programs, but it just scored a deal that could make it an important name in the spaceflight industry. United Launch Alliance has chosen Blue Origin’s BE-4 engine (two of them, to be exact) to power the booster stage its next-generation Vulcan Centaur rocket, which is due to launch in mid-2020. Jeff Bezos’ outfit won’t be the only rocket vendor involved, but it crucially beat out Aerojet Rocketdyne — a behemoth in the industry that had tried to pressure ULA into avoiding Blue Origin tech altogether.
