Reaction Engines

About us

Reaction Engines is a UK-based company formed in 1989 to design and develop the technologies needed for a new class of innovative hypersonic propulsion system – the Synergetic Air-Breathing Rocket Engine (SABRE™).

We have achieved a breakthrough in aerospace engine technology by developing ultra-lightweight heat exchangers. Developed for our high speed SABRE engines, the heat exchangers stop engine components from overheating at high flight speeds.

In addition to the SABRE development programme, Reaction Engines offers a unique and extensive range of capabilities, from propulsion systems and advanced heat exchanger design and development, through to advanced manufacturing, precision machining and fabrication.

We have begun partnering with aerospace suppliers to deliver a ground-based SABRE demonstrator engine. There’s never been a better time to join us on the journey.
