Rocket Engines Designed for Reuse
Our Approach to Engines
Operationally reusable rockets demand high performance engines capable of deep throttling for soft landings. Built for multiple uses, our family of engines is powering the next generation of rockets for commercial, civil, national security and human spaceflight.
Blue Engines are designed, developed and manufactured at our headquarters in Kent, Washington. We’re now preparing for serial production of our most powerful engine, the BE-4, in Huntsville, Alabama. All our engines and propulsion subsystems are thoroughly tested and qualified in Van Horn, Texas.
The BE-3 is the first new liquid hydrogen-fueled rocket engine to be developed for production in America in over a decade.
The first ox-rich staged combustion engine made in the U.S. will power the next generation of American orbital rockets.
BE-7 is an additively manufactured, high-performance, dual-expander cycle engine, generating 40 kN (10,000 lbf) thrust.
|BE - 1||Peroxide||9 kN (2,000 lbf) at Sea Level|
|BE - 2||Kerosene + Peroxide||140 kN (31,000 lbf) at Sea Level|
|BE - 3PM||Liquid Hydrogen + Liquid Oxygen||490 kN (110,000 lbf) at Sea Level|
|BE - 3U||Liquid Hydrogen + Liquid Oxygen||710 kN (160,000 lbf) in Vacuum|
|BE - 4||Liquefied Natural Gas + Liquid Oxygen||2,400 kN (550,000 lbf) at Sea Level|
|BE - 7||Liquid Hydrogen + Liquid Oxygen||40 kN (10,000 lbf) in Vacuum|
