The Aérospatiale Gazelle (company designations SA 340, SA 341 and SA 342) is a French five-seat helicopter, commonly used for light transport, scouting and light attack duties. It is powered by a single Turbomeca Astazou turbine engine and was the first helicopter to feature a fenestron tail instead of a conventional tail rotor. It was designed by Sud Aviation, later Aérospatiale, and manufactured in France and the United Kingdom through a joint production agreement with Westland Aircraft. Further manufacturing under license was performed by SOKO in Yugoslavia and the Arab British Helicopter Company (ABHCO) in Egypt.

Since being introduced to service in 1973, the Gazelle has been procured and operated by a number of export customers. It has also participated in numerous conflicts around the world, including by Syria during the 1982 Lebanon War, by Rwanda during the Rwandan Civil War in the 1990s, and by numerous participants on both sides of the 1991 Gulf War. In French service, the Gazelle has been supplemented as an attack helicopter by the larger Eurocopter Tiger, but remains in use primarily as a scout helicopter.



La Gazelle est un hélicoptère léger polyvalent de construction métallique conçu dans la deuxième moitié des années 1960 par Sud-Aviation et produit en série à partir du début des années 1970 par la Société nationale industrielle aérospatiale (SNIAS ou Aérospatiale) en collaboration avec Westland Helicopters (Royaume-Uni). L'appareil est décliné en deux versions commerciales principales (nomenclatures SA 341 et SA 342). La majeure partie de sa production est destinée aux armées (France, Tunisie, Maroc, Royaume-Uni, Yougoslavie, Égypte, Koweït, Irak, soit 38 clients entre 1980 et 1988²) mais la Gazelle connait aussi un succès certain dans les milieux civils.

Malgré son ancienneté, la Gazelle forme encore en 2015 la force principale des hélicoptères de combat de plusieurs pays.
