Aérospatiale Alouette III

The Aérospatiale Alouette III (Lark) is a single-engine, light utility helicopter developed by French aircraft company Sud Aviation. During its production life, it proved to be a relatively popular rotorcraft; including multiple licensed manufacturers, in excess of 2,000 units were constructed.

The Alouette III was developed as an enlarged derivative of the earlier and highly successful Alouette II. Sharing many elements with its predecessor while offering an extra pair of seats and other refinements, it quickly became a commercial success amongst both civil and military customers. Further variants were also developed; amongst these was a high-altitude derivative, designated as the SA 315B Lama, entered operational service during July 1971. The Alouette III was principally manufactured by Aérospatiale; the type was also built under license by Hindustan Aeronautics Limited (HAL) in India as the HAL Chetak, by Industria Aeronautică Română (IAR) in Romania as the IAR 316 and F+W Emmen in Switzerland.

Similar to the Alouette II, in military service, it was used to perform missions such as aerial observation, photography, air-sea rescue, liaison, transport and training; it could also be armed with anti-tank missiles, anti-shipping torpedoes, and a fixed cannon. In a civilian capacity, the Alouette II was commonly used for casualty evacuation (often fitted with a pair of external stretcher panniers), crop-spraying, personnel transportation, and for carrying external loads.
