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
British Aerospace Sea Harrier in 1973, and are now popularly recognised as aircraft carriers. Almost immediately upon their construction, a ski-jump was added to the end of the 170-metre deck, enabling the carriers to effectively operate a small number of V/STOL jets. The Royal Air Force's Hawker Siddeley Harrier GR1s had entered service in April 1969. A navalised variant of the Harrier was developed by Hawker Siddeley to serve on the upcoming ships; this became the Sea Harrier. In 1975, the Royal Navy ordered 24 Sea Harrier "FRS.1" (standing for 'Fighter, Reconnaissance, Strike') aircraft, the first of which entered service in 1978. During this
