Blue Origin Engines
Rocket Engines Designed for Every Mission
High-Performance Engines
Blue Origin’s engines are powering the next generation of reusable launch and space vehicles for commercial, civil, national security, and human spaceflight. Our propulsion systems are made in America for a full range of applications.
BE-4
Thrust: 640,000 lbf (2,846 kN) with deep throttle capability to 220,000 lbf (978 kN)
Propellant: Liquid oxygen and liquefied natural gas
The first oxygen-rich staged combustion engine made in the U.S. powers two vehicles in the next generation of American orbital rockets. Seven BE-4 engines power New Glenn's reusable booster, and two BE-4 engines drive the first stage of United Launch Alliance's Vulcan launch vehicle.
BE-3U
Thrust: 200,000 lbf (890 kN) with ability to throttle to 100,000 lbf (445 kN)
Propellant: Liquid oxygen and liquid hydrogen
Two restartable BE-3U engines power New Glenn’s 7x2 upper stage and four restartable engines power the 9x4 vehicle, enabling a wide range of customer missions including direct injection to geostationary orbit. BE-3U is an open-expander cycle engine.
BE-7
Thrust: 10,000 lbf (44.5 kN) with deep throttle capability to 2,000 lbf (8.9kN)
Propellant: Liquid hydrogen and liquid oxygen
Blue Moon’s BE‑7 engine is a dual-expander cycle that delivers high specific impulse and deep throttling capabilities, making it ideal for carrying large payloads to the Moon.
BE-3PM
Thrust: 110,000 lbf (490 kN) with deep throttle capability to 20,000 (90 kN)
Propellant: Liquid oxygen and liquid hydrogen
The first new liquid hydrogen-fueled rocket engine to be developed for production in America in over a decade. On November 23, 2015, BE-3PM powered New Shepard’s Propulsion Module above the Kármán line and reignited for a soft landing on its history-making flight to space and back, and on July 20, 2021, completed its first human flight. BE-3PM carried 98 humans above the Kármán line and supported 38 missions. When returning to Earth, it uniquely throttles down to 20,000 lbf (90 kN), enabling a gentle vertical landing on the pad.
