Blue Engines

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.

Engine
BE-3

The BE-3 is the first new liquid hydrogen-fueled rocket engine to be developed for production in America in over a decade.

Engine
BE-4

The first ox-rich staged combustion engine made in the U.S. will power the next generation of American orbital rockets.

Engine
BE-7

BE-7 is an additively manufactured, high-performance, dual-expander cycle engine, generating 40 kN (10,000 lbf) thrust.
