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 P.1127 after the P.1154's selection over the Dassault Mirage IIIV. Following the termination of the P.1154, the RAF then began studying a straightforward upgrade of the Kestrel as a production aircraft; accordingly, it issued Requirement ASR 384, which sought a V/STOL ground attack jet, known as the "P.1127 (RAF)". In late 1965, the RAF placed an order for six pre-production P.1127 (RAF) aircraft. On 31 August 1966, the first of these P.1127 (RAF) aircraft made its maiden flight. In early 1967, an order for 60 production aircraft was formally received by Hawker Aviation; at this time the aircraft received the "Harrier
