The Aérospatiale Alouette II (, Lark) is a light helicopter originally manufactured by Sud Aviation and later Aérospatiale, both of France. The Alouette II was the first production helicopter to use a gas turbine instead of a conventional heavier piston engine.
The Alouette II was mostly used for military purposes in observation, photography, air-sea rescue, liaison and training but it has also carried anti-tank missiles and homing torpedoes. As a civilian helicopter it was used for casualty evacuation (with two external stretcher panniers), crop-spraying and as a flying crane (with a 500 kg external sling load).
