Aérospatiale Alouette II
utility helicopter family by Sud Aviation

The Aérospatiale Alouette II (French pronunciation: [alwɛt], "lark"; company designations SE 313 and SA 318) is a French light helicopter originally manufactured by Sud Aviation and later Aérospatiale. It was the first conventional production helicopter powered by a gas turbine engine instead of the heavier conventional piston powerplant.
On 12 March 1955, the prototype SE 3130 performed its maiden flight. The Alouette II was a widely used type and popular with operators, with over 1,300 rotorcraft eventually being constructed between 1956 and 1975. The type was predominantly used for military purposes in observation, photography, air-sea rescue, liaison and training. It has also carried anti-tank missiles and homing torpedoes. In civilian roles, the Alouette II has been used for medical evacuation (with two external stretcher panniers), crop-spraying, and as a flying crane—with a 500-kilogram (1,100 lb) external underslung load.
A high-altitude derivative, the SA 315B Lama, was developed and entered operational service in July 1971. The Alouette II also was further developed into the larger and more powerful Alouette III. In 1975, production of the type was terminated, having been effectively succeeded by these newer rotorcraft. Despite it being long out of production, considerable numbers of Alouette II were still in service at the start of the 21st century.

Why this record matters
“Aérospatiale Alouette II” is worth following because a concise public description often conceals a longer documentary argument. Here, Aérospatiale, Alouette and utility provides the most credible route into that argument.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q316815. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1955, 1956, 1975 and 1971.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
