The Aérospatiale Alouette III (Lark), company designations SA 316 and SA 319, 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 licence 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 III was commonly used for casualty evacuation (often fitted with a pair of external stretcher panniers), crop-spraying, personnel transportation, and for carrying external loads. By the 2010s, many operators were in the process of drawing down their fleets and replacing them with more modern types; the French military intend to replace their Alouette IIIs with the newly-developed Airbus Helicopters H160.


The Alouette III has its origins with an earlier helicopter design by French aircraft manufacturer Sud-Est, the SE 3120 Alouette, which, while breaking several helicopter speed and distance records in July 1953, was deemed to have been too complex to be realistic commercial product. Having received financial backing from the French government, which had taken an official interest in the venture, the earlier design was used as a starting point for a new rotorcraft that would harness the newly developed turboshaft engine; only a few years prior, Joseph Szydlowski, the founder of Turbomeca, had successfully managed to develop the Artouste, a 260 hp (190 kW) single shaft turbine engine derived from his Orédon turbine engine. This engine was combined with the revised design to quickly produce a new helicopter, initially known as the SE 3130 Alouette II.

During April 1956, the first production Alouette II was completed, becoming the first production turbine-powered helicopter in the world. The innovative light helicopter, soon broke several world records and became a commercial success. As a result of the huge demand for the Alouette II, manufacturer Aérospatiale took a great interest in the development of derivatives, as well as the more general ambition of embarking on further advancement in the field of rotorcraft.

In accordance with these goals, the company decided to commit itself to a new development programme with the aim of developing a more powerful helicopter that would be capable of accommodating up to 7 seats or a pair of stretchers. The design team was managed by French aerospace engineer René Mouille. The design produced, which was initially designated as the SE 3160, featured several improvements over the Alouette II; efforts were made to provide for a higher level of external visibility for the pilot as well as for greater aerodynamic efficiency via the adoption of a highly streamlined exterior.


SA 316B:
powered by a 425 kW (570 shp) Turboméca Artouste IIIB turboshaft engine, with strengthened main and tail rotor for greater performance. The SA 316B was built under licence in India as the HAL Chetak, and again under licence in Romania as the IAR 316.


SA 319B:
was a direct development of the SA 316B, it was powered with a 649 kW (870 shp) Turbomeca Astazou XIV turbo shaft engine, but it was derated to 447 kW (660 hp).

French Marine Nationale has ordered thirty-seven SA-316B, SA-316B VSV and SA-319B Alouette IIIs.

The first SA316Bs were assigned to Escadrille 20S (Saint Raphael 1962/1991) and Escadrille 23S (Saint-Mandrier August 1962/1999) which supplied the "PEDRO"-detachments to the aircraft carriers Foch and Clemenceau) and Escadrille 22S (reactivated at Lanvéoc- Poulmic on 1 August 1964 in support of the 2nd RM and to ensure the PEDRO detachments of the French carriers, then based in Brest).

In 1972 Escadrille 22S received the SA316B VSV for the training of the crews, becoming in 1976 the ESHE (embarked helicopter school).

The arrival of the SA319B equipped with two Mk-46 torpedoes made it possible to create the anti-submarine warfare (ASW) units Flottille 34F and Flottille 35F.

The Alouette III was the first ASW helicopter to embark on the Tourville type frigates.

Flottille 35F, which used Alouette III from June 1979 to its dissolution in January 1990, was recreated on 1 October 1999 by merging Flottille 33F and Escadrille 23S.
Its six Alouette IIIs were replaced in 2003 by Westland Lynx.

The SA316Bs assigned to the SAR and PEDRO missions being replaced by the AS365F Dauphin.
The 13 SA319 still in service in French Navy in 2016 are expected to continue flying until 2026.
