de Havilland Super Sprite
The de Havilland Super Sprite, the first liquid-propellant rocket engine to have successfully completed a British Government Type-Approval Test, which was in full production for the Royal Air Force. The engine was fitted to the Vickers Valiant four-jet bomber within droppable containers. The Super Sprite rocket engine was used as a boost engine for the Vickers Valiant V-bomber and a pair were installed between the exhausts of the Ghost engines of the DH106 Comet 1 prototype for test purposes. The thrust was generated by the decomposition of hydrogen peroxide with a chemical catalyst.
