BAE Systems and Reaction Engines to develop a groundbreaking new aerospace engine

BAE Systems and Reaction Engines Ltd. today announced a strategic investment by BAE Systems and a working collaboration to accelerate the development of SABRE – a new class of aerospace engine that combines both jet and rocket technologies and could potentially revolutionise hypersonic flight and the economics of space access.

Under the terms of the agreement, BAE Systems will invest £20.6 million in Reaction Engines to acquire 20 per cent of its share capital and also enter into a working partner relationship. The working partnership will draw on BAE Systems' extensive aerospace technology development and project management expertise and will provide Reaction Engines with access to critical industrial, technical and capital resources to progress towards the demonstration of a ground-based engine – a key milestone in the development of the technology. Under the agreement, BAE Systems will enter into a preferred supplier relationship with Reaction Engines in certain agreed areas and will have representation on the board of Reaction Engines.

Reaction Engines is a privately held company based in the United Kingdom developing the technologies needed for an advanced combined cycle air-breathing rocket engine called SABRE (Synergetic Air-Breathing Rocket Engine). This new class of aerospace engine is designed to enable aircraft to operate from standstill on the runway to speeds of over five times the speed of sound in the atmosphere. SABRE can then "transition" to a rocket mode of operation, allowing spaceflight at speeds up to orbital velocity, equivalent to 25 times the speed of sound. Reaction Engines' technology has undergone extensive independent technical assessments which have confirmed its viability and potential applications.

A key element of the SABRE engine is a breakthrough in aerospace engine technology of ultra-lightweight heat exchangers that allow the cooling of very hot airstreams from over 1,000 °C to minus 150 °C in less than 1/100th of a second, whilst preventing the formation of ice at sub-zero temperatures.

The UK Government is expected to confirm grant funding of £60 million for Reaction Engines to further SABRE's development towards a ground-based test engine and to investigate its applications for space access vehicles. Together with BAE Systems' investment, this injection of capital will support the transition from a research phase into development and testing of the engine. The ground-based test engine is expected to be ready by 2020 and the first unmanned test flights could happen by 2025.

Mark Thomas, Managing Director of Reaction Engines: "Today's announcement represents an important landmark in the transition of Reaction Engines – from a company that has been focused on the research and testing of enabling technologies for the SABRE engine, to one that is now focused on the development and testing of the world's first SABRE engine. BAE Systems brings industry-leading capabilities in programme delivery and wider engineering systems integration that will accelerate the development of SABRE as a new engine class and its vehicle applications. This partnership builds on the outstanding technical breakthroughs that Reaction Engines has made and the positive assessments received on the potential of the technology from experts at the European Space Agency and the United States' Air Force Research Laboratory."

Nigel Whitehead, Group Managing Director, Programmes & Support, BAE Systems: "Reaction Engines is a highly innovative UK company and our collaboration gives BAE Systems a strategic interest in a breakthrough air and space technology with significant future potential. Our partnership with Reaction Engines is part of our sustained commitment to investing in and developing prospective emerging technologies. BAE Systems' considerable engineering and development expertise will help support the delivery of the first demonstrator for the SABRE engine."

Jo Johnson MP, UK Minister for Universities and Science said: "This investment by BAE Systems reflects the strength of British engineering and technology and our ambitions as a leading space nation. I am sure that this partnership will strengthen both organisations – helping to create more jobs in the UK's growing space sector and ultimately to make the SABRE engine a reality."
