Aérospatiale SA 330 Puma

The Aérospatiale SA 330 Puma is a four-bladed, twin-engined medium transport/utility helicopter designed and originally produced by the French aerospace manufacturer Sud Aviation.

The Puma was originally developed as an all-new design during the mid-1960s in response to a French Army requirement for a medium-sized all-weather utility helicopter. Powered by a pair of Turbomeca Turmo turboshaft engines, it was designed to transport up to 16 seated soldiers, or a maximum of litters with four attendants for casualty evacuation duties, along with carrying up to 2500 kg of cargo either internally or using an external sling. The design of the Puma incorporated several innovations, including an automatic blade inspection system and relatively advanced anti-vibration measures integrated into both the main gearbox and main rotor blades. It was also designed to be capable of operating at nighttime, under inhospitable flying conditions and across a wide range of climates from Arctic to desert environments. The Puma also has an intentionally high level of reserve power to permit effective flight even at its maximum weight with only a single operational engine.

On 15 April 1965, the first prototype performed its maiden flight; the first production standard Puma made its first flight during September 1968. Deliveries to the French Army commenced in early 1969; the type quickly proved itself to be a commercial success. Production of the Puma continued into the 1980s under Sud Aviation's successor company Aérospatiale. It was also license-produced in Romania as the IAR 330; two unlicensed derivatives, the Denel Rooivalk attack helicopter and Atlas Oryx utility helicopter, were built in South Africa. Several advanced derivatives have been developed, such as the AS332 Super Puma and AS532 Cougar, and have been manufactured by Eurocopter and its successor company Airbus Helicopters since the early 1990s. These descendants of the Puma remain in production in the 21st century.

The Puma has seen combat in a range of theatres by a number of different operators; significant operations include the Gulf War, the South African Border War, the Portuguese Colonial War, the Yugoslav Wars, the Lebanese Civil War, the Iraq War, and the Falklands War. Numerous operators have chosen to modernise their fleets, often adding more capabilities and new features, such as glass cockpits, Global Positioning System (GPS) navigation, and various self-defense measures. The type also saw popular use in the civilian field and has been operated by a number of civil operators. One of the largest civil operators of the Puma was Bristow Helicopters, which regularly used it for off shore operations over the North Sea.
