Named after a bird of prey, it was originally developed by British manufacturer Hawker Siddeley in the 1960s. The Harrier emerged as the only truly successful V/STOL design of the many attempted during that era, despite being a subsonic aircraft, unlike most of its competitors. It was conceived to operate from improvised bases, such as car parks or forest clearings, without requiring large and vulnerable air bases. Later, the design was adapted
British Aerospace Sea Harrier time Hawker Siddeley became part of British Aerospace through nationalisation in 1977. By the time the prototype Sea Harrier was flown at Dunsfold on 20 August 1978 the order had been increased to 34. The Sea Harrier was declared operational in 1981 on board the first "Invincible" class ship HMS "Invincible", and further aircraft joined the ageing HMS "Hermes" aircraft carrier later that year. Following their key role in the 1982 Falklands War, several lessons were learned from the aircraft's performance, which led to approval for an upgrade of the fleet to "FRS.2" (later known as "FA2") standard to be
