Sydney Camm went into service, serving with the Royal Navy from 1947 to 1955. After the Second World War, Camm created many jet-powered designs which would become important aircraft in the Cold War era. Notable among Camm's post-war work is his contribution to the design of the Hawker Siddeley P.1127 / Kestrel FGA.1, the progenitor of the Hawker Siddeley Harrier. The Harrier is a well-known vertical takeoff and landing (VTOL) aircraft designed at Hawker Siddeley, which would later merge into British Aerospace, now known as BAE Systems. The Harrier was one of the radical aircraft which took shape in postwar Britain, which
Hawker Siddeley Harrier difficulties were unavoidable in order to create a V/STOL aircraft. The Pegasus turbofan jet engine, developed in tandem with the P.1127 then the Harrier, was designed specifically for V/STOL manoeuvring. Bristol Siddeley developed it from their earlier conventional Orpheus turbofan engine as the core with Olympus compressor blades for the fan. The engine's thrust is directed through the four rotatable nozzles. The engine is equipped for water injection to increase thrust and takeoff performance in hot and high altitude conditions; in normal V/STOL operations the system would be used in landing vertically with a heavy weapons load. The water injection
