Westland Sea King Mk50A

Westland Sea King Mk50A

The Fleet Air Arm operates Westland Sea King Mk50A helicopters – 10 were delivered in 1975, to replace the Westland Wessex as the RAN’s anti-submarine warfare helicopter, and an additional two arrived in 1983. The Sea King Mk 50A is an all-weather twin engine multi-role helicopter designed by Sikorsky in the USA and built under licence by Westland Helicopters at Yeovil in the UK. The aircraft were used in the anti-submarine warfare and submarine training role until 1995 when the AQS-13B sonar was removed from service. Since that time, the Sea King’s primary role has been maritime utility support. Secondary roles include ASW weapons carrier, anti-surface warfare, troop transport and sea-air rescue. The Sea King helicopter will end its navy service life at the end of 2011.
