context_page_description: The Westland Wasp was a small 1960s British turbine powered, shipboard anti-submarine helicopter. Produced by Westland Helicopters, it came from the same P.531 programme as the British Army Westland Scout, and was based on the earlier piston-engined Saunders-Roe Skeeter. It fulfilled the requirement of the Royal Navy for a helicopter small enough to land on the deck of a frigate and carry a useful load of two homing torpedoes.
  The Wasp sunk one ship in combat, seriously damaging the ARA Santa Fe submarine in 1982 during the Falklands war.
context_section_description: The Wasp HAS.1 was introduced to service in the small ships role in 1964, after an intensive period of trials by 700(W) IFTU between June 1963 and March 1964. It served in this primary role with 829 Naval Air Squadron, but also in training units to supply crews for the front line with 706 NAS between 1965 and 1967 and in 703 NAS between 1972 and 1981. Single airframes also served for light liaison duties in the Commando Assault squadrons, 845 NAS and 848 NAS until 1973. Although effective as a submarine killer, it was best deployed paired with a Wessex HAS.3 submarine hunter. In the late 1970s, the Westland Lynx started to replace the Wasp.
  On 25 April 1982 the Argentinian submarine ARA Santa Fe was spotted by a Wessex helicopter from HMS Antrim. The Wessex and a Westland Lynx HAS.2 from HMS Brilliant then attacked it with depth charges, a Mk 46 torpedo, and also strafed it with GPMG. A Wasp launched from HMS Plymouth and two Wasps launched from HMS Endurance fired AS.12 anti-ship missiles at the submarine, scoring hits. Santa Fe was damaged badly enough to prevent her from submerging. The crew abandoned the submarine at the jetty on South Georgia and surrendered to the British forces, thus becoming the first casualty of the sea war, as well as the first direct engagement by the Royal Navy Task Force.
  The last Wasp was finally withdrawn from service in 1988 when the last of the Type 12 Rothesay-class frigates was decommissioned.
