About Reaction Engines Stock

Reaction Engines is a privately held company based in the United Kingdom developing 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 hypersonic speeds of over five times the speed of sound in the atmosphere. If higher speeds are required, SABRE can then transition to a rocket mode of operation, allowing spaceflight at speeds up to orbital velocity, equivalent to twenty five times the speed of sound. Reaction Engines’ technology has undergone extensive independent technical assessments which have confirmed its viability and potential vehicle applications. REL's world leading heat exchange and advanced manufacturing capabilities have numerous applications in aerospace, cleantech, energy and other applications
