Making beyond possible.

Our Mission.

The sky’s no longer the limit. The development of our innovative Synergetic Air-Breathing Rocket Engine (SABRE) is enabling us to go beyond everything that has gone before – from making space and hypersonic travel more efficient and more accessible, to applying our latest breakthroughs to bring a step-change in performance and efficiency to an array of commercial industries. We’re making it possible.

Reaction Engines completes further validation of SABRE technology

We are pleased to announce that we have completed the testing of two vital sub-systems of SABRE; the HX3 heat exchanger and the advanced hydrogen preburner. These sub-systems supply heat energy and air to the air-breathing core of the engine. Alongside our partners at Airborne Engineering and S&C Thermofluids, we have been able to conduct agile and robust testing campaigns in challenging circumstances. These experiments have yielded high levels of insight and expertise and are the latest in a wider series designed to validate SABRE technology.
