During the Falklands War, a number of warships were lost due to the lack of an indigenous AEW presence. Consequently, a greatly accelerated project was started to equip Westland Sea King helicopters with a slightly modified version of the system known as Searchwater LAST (Low Altitude Surveillance Task). The radome was mounted in a distinctive inverted cupola on a swivel arm attached to the right side of the fuselage just aft of the main door. This arm allowed the helicopter to lower the radar below the fuselage in flight and to raise it for landing."@en . "Searchwater radar"@en .

Searchwater radar was developed by the Royal Signals and Radar Establishment and EMI (later Thorn Sensors Group). Racal Radar Defence Systems acquired Searchwater in 1995. Thorn and Racal merged to form Racal-Thorn Defence."@en .
