Reaction Engines

We develop pioneering technology to elevate life on Earth. Innovating in pursuit of the world's net zero goals. We deliver thermal management solutions to create a better, more sustainable future. We are a privately owned British aerospace Company known for our pioneering work in air-breathing rocket engine technology, particularly SABRE. Originally established with a focus on this innovative propulsion system, we have since expanded efforts to include hypersonic propulsion and defence applications and sustainable technology solutions for aerospace and other industries. As an award-winning innovator, Reaction Engines is increasingly using its microtube technology and thermal management solutions to address the challenges of achieving zero carbon. Collaborating with industry leaders and government agencies, we are working on solutions for zero carbon aviation, including battery electric flight, fuel cell-powered aircraft, and researching next-generation hydrogen-fuelled jet engines. With headquarters in Culham, Oxfordshire, UK, and a high temperature test facility in Denver, Colorado, US, we are actively pursuing commercialisation and have developed several unique products, including low drag radiators and compact charge air coolers.
