It was essentially the ultimate development of the company's Kestrel engine, which had seen widespread use in military aircraft of the pre-war period. Due to the wartime priority of Rolls-Royce Merlin development and production, the Peregrine saw limited use and was cancelled with only 301 engines being built. During the 1930s the use of superchargers to increase "effective displacement" of an aircraft engine came into common use. Charging of some form was a requirement for high-altitude
Rolls-Royce RZ.2 Rolls-Royce RZ.2 The RZ.2 was a British design for a liquid oxygen (LOX) / kerosene-fuelled rocket engine to power the Blue Streak (missile). The design was a development of the Rolls-Royce RZ.1 rocket engine, which had in turn been a development by Rolls-Royce of the Rocketdyne S-3D.. Rolls-Royce, Ansty was the design authority. Two variants of this engine were developed: the first provided a static thrust of and the second (intended for the three stage satellite launch vehicle) . The engines were unique at that time in that they could be vectored by seven degrees in flight for guidance. Some
