SEA KING HC.4 ZF112
This airframe was one of forty two Sea King HC.4 built and saw her first flight in 1982 and was subsequently flown by 846, 845 and 848 NAS. The ZF112 is now owned by Andrew Whitehouse and is being restored to flight by the Historic Helicopters team.
The Westland WS-61 Sea King is a British licence-built version of the American Sikorsky S-61 helicopter of the same name, built by Westland Helicopters. The aircraft differs considerably from the American version, with Rolls-Royce Gnome engines (derived from the US General Electric T58), British-made anti-submarine warfare systems and a fully computerised flight control system. The Sea King was primarily designed for performing anti-submarine warfare (ASW) missions. A Sea King variant was adapted by Westland as a troop transport and was known as the Commando.
In British service, the Westland Sea King provided a wide range of services in both the Royal Navy and the Royal Air Force. As well as wartime roles in the Falklands War, the Gulf War, the Balkans conflict, the Iraq War and the Afghanistan War. The Sea King is perhaps most well known in its capacity as a Royal Navy Search and Rescue (red and grey livery) and RAF Search and Rescue Force (yellow livery) helicopter. The Sea King was also adapted to meet the Royal Navy’s requirement for a ship-based airborne early warning platform.
