Pioneering a new class of propulsion for reusable launch vehicles

Our goal is to deliver a truly versatile propulsion system - a hybrid air-breathing rocket engine that can power an aircraft from a standing start to over five times the speed of sound for hypersonic flight in the atmosphere, and over 25 times the speed of sound for space access. With its wide range of operation and scalability, the Synergetic Air-Breathing Rocket Engine (SABRE™) represents a defining moment in powered flight.



A new class of engine for propelling both high speed aircraft and spacecraft.
