took over Anti-Submarine Warfare Operational and Advanced Flying Training, with the squadron regularly detached to RFA Engadine for seaborne training. The Sea King helicopters were later passed over to 826 NAS in June 1975, enabling 737 NAS to concentrate on Wessex HAS.3 training duties. On the 7th February 1983, 737 NAS disbanded at RNAS Portland, handing over its Wessex HAS.3 helicopters to 772 NAS. Helicopter-only squadron From 28 August 1959 the squadron only used helicopters. 737 NAS was assigned to operate from Helicopter Support Ship RFA Engadine and later, from the flight decks of the eight County Class guided missile destroyers, including HMS Glamorgan (D19), HMS Antrim (D18) and HMS Norfolk (D21). 737 Squadron supported flights on these destroyers in addition to providing aircrew training at RNAS Portland. In their ship-borne, anti-submarine role, the HAS.3s could carry two Mark 44 torpedoes or Mark 46 torpedoes (with parachutes) or four Mk.11 Depth Charges in addition to their Plessey dipping Sonar. They could also be fitted with a door-mounted Machine gun and act as a self-contained unit, handling all operations of Anti-submarine warfare(ASW). Throughout the late 1970s most of the Wessex HAS.3 helicopters at RNAS Portland were being replaced by Westland Sea Kings, which could carry more torpedoes or depth charges and had the security of twin engines, with greatly extended endurance. Falklands War was the Flagship of Operation Paraquet, the recovery of South Georgia in April 1982. Her helicopter, Westland Wessex HAS.3 XP142, nicknamed Humphrey, was responsible for the rescue of 16 SAS men from Fortuna Glacier and the subsequent detection and disabling of the Argentine submarine Santa Fe. Another HAS.3, XM837, was lost in June 1982 when an Exocet missile hit the hangar on the destroyer . A few HAS.3s remained in service after the Falklands War period. One of these, XP142, was seriously damaged near San Carlos Water and was replaced on HMS Antrim by XM328 in November 1982. XM328 then sailed with HMS Antrim on her second deployment to the South Atlantic. Decommissioning XM328 was transferred to 772 Naval Air Squadron when 737 Squadron disbanded on 4 February 1983. XP142 is preserved in the Fleet Air Arm Museum at Yeovilton.
