Reaction Engines, a UK-based aerospace company, is in discussions with Whitehall to secure a £20 million financial boost to support the continued development of its revolutionary hybrid jet-rocket engine amid mounting losses and slow revenue growth. The company aims to pioneer a new era of hypersonic flight, promising that its engines could one day reduce travel time across the globe to just a few hours.
The company’s flagship technology, the “Sabre” engine (Synergetic Air Breathing Rocket Engine), has been under development for years and is designed to achieve speeds of Mach 5 within Earth’s atmosphere and potentially Mach 25 in space. To put that into perspective, Mach 5 is more than three times faster than the iconic Concorde and over twice the speed of the SR-71 Blackbird, the world’s fastest jet-powered aircraft. These advances could enable the creation of high-speed planes, referred to as the “Sons of Concorde.”
