The Westland Wessex was a British-built turbine-powered development of the Sikorsky H-34. It was developed and produced under licence by Westland Aircraft (later Westland Helicopters). One of the main changes from Sikorsky’s H-34 was the replacement of the piston-engine powerplant with a turboshaft engine; the Wessex was the first large mass-produced helicopter designed around use of a gas turbine engine. Early models were powered by a single Napier Gazelle engine, while later builds used a pair of de Havilland Gnome engines.
The Wessex was initially produced for the Royal Navy (RN) and later for the Royal Air Force (RAF); a limited number of civilian aircraft were also produced, as well as some export sales. The Wessex operated as an anti-submarine warfare and utility helicopter; it is perhaps best recognised for its use as a search and rescue (SAR) helicopter. The type entered operational service in 1961, and had a service life in excess of 40 years before being retired in Britain.
