The Messerschmitt Me 163 Komet was a German rocket-powered interceptor aircraft.
It is the only rocket-powered fighter aircraft ever to have been operational and the first piloted aircraft of any type to exceed 621 mph in level flight.
Over 300 Komets were built, but the aircraft proved lacklustre in its dedicated role as an interceptor and destroyed between 9 and 18 Allied aircraft against 10 losses.
Me 163B, Werknummer 191614, has been at the RAF Museum site at RAF Cosford, since 1975. Before then, it was at the Rocket Propulsion Establishment at Westcott, Buckinghamshire. This aircraft last flew on 22 April 1945, when it shot down an RAF Lancaster.
