in June 1967. In 1966, 829 NAS also received two Wessex HU5s for operation from the Royal Fleet Auxiliaries and . Responsibility for the ice patrol ship was also taken over in 1966, initially using Whirlwind HAR1s. These were soon replaced by Whirlwind HAR9s, which transferred to in 1968, and were eventually replaced by Wasp helicopters in 1976. In June 1970, responsibility for small ships' Wessex helicopters was transferred to 737 Naval Air Squadron at RNAS Portland. A further restructuring took place in January 1972 when 703 Naval Air Squadron was established at RNAS Portland to take over the Wasp conversion and operational flying training role. This task was reassigned to 829 NAS in January 1981. In August 1982, the operation of Wessex HAS3 anti-submarine detachments was returned to 737 NAS. Falklands War Eleven Westland Wasp HAS1 helicopters of 829 NAS participated in the Falklands War in 1982. They were embarked in the Type 21 frigate , the es and , the ice patrol ship HMS Endurance, MV Contender Bezant and the survey ships , , and . On 25 April 1982, the Argentinian submarine Santa Fe was spotted by a Wessex HAS3 from . The Wessex then attacked it with depth charges. launched a Wasp HAS1 helicopter, and launched a Westland Lynx HAS2. The Lynx attacked the submarine with a MK 46 torpedo, and also strafed it with its pintle-mounted GPMG; the Wessex also fired on Santa Fe with its GPMG. The Wasp from HMS Plymouth as well as two other Wasps launched from 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 at King Edward Point 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 The last Wasp was finally withdrawn from service in 1988 when the last of the Type 12 Rothesay-class frigates was decommissioned. Starting in September 1986 829 NAS had already received a number of Westland Lynx HAS2 detachments transferred from 815 Naval Air Squadron. In 1988 the squadron eventually had up to 30 Lynx. Flights were regularly deployed on the Armilla patrol in the Persian Gulf. The squadron was awarded the "Boyd Trophy" jointly with 815 NAS for their service in the
