The global space sector is in a period of unprecedented transformation and growth. Space launch, which was once the domain of National Space Agencies and multinational primes, is now becoming accessible to companies and enterprising organisations of all sizes. In the last century, the jet engine invented by Sir Frank Whittle was arguably the most significant innovation in transportation since the railway. Now we are on the cusp of a new revolution, as the promise of hypersonic transportation brings the world even closer together and makes space ever more accessible.

New technologies are being developed today that will enable truly affordable and routine access to space, changing the paradigm that space will always be expensive and out of reach. Reaction Engines Ltd, a British SME based in Oxfordshire, is one of the companies leading the way and driving this future vision. With state-of-the-art engineering based on pioneering technology entirely developed in the UK, the unique Synergetic Air Breathing Rocket Engine (SABRE) concept is quite literally game changing. SABRE is as significant an invention as the jet engine, the first in a new class of propulsion system that has the potential to deliver a breakthrough in air and space transportation.

Twice as fast as the fastest jet engine and many times more efficient than the world’s best rocket engines, SABRE enables air-breathing flight from standstill to over five times the speed of sound (hypersonic), before switching to a higher thrust rocket mode. SABRE’s versatility will enable aircraft-like horizontal take-off and landing operations, radically improving the affordability and responsiveness of access to space. SABRE technology is also well…
