The Aérospatiale SA 330 Puma is a four-bladed, twin-engined medium transport/utility helicopter. The Puma was originally manufactured by Sud Aviation of France. In 1967, the Puma was also selected by the Royal Air Force (RAF) and given the designation Puma HC Mk 1. As a result of this decision, the SA 330 was included in a joint production agreement between Aerospatiale and Westland Helicopters of the UK, which also resulted in the purchase of Aérospatiale Gazelle by the United Kingdom and the Westland Lynx by France. This resulted in Westland building components for the Puma, and assembling the RAF’s Pumas.
