The Alouette II is capable of accommodating a seating arrangement for up to five personnel, including the pilot; access to the cabin was provided via a pair of side-hinged doors. The compact cockpit was provided with a dome-shapred windscreen which provided for excellent levels of external visibility. The Alouette II also made innovative use of armaments. It was the first helicopter worldwide to be equipped with anti-tank munitions in the form of the SS.11 MCLOS wire-guided anti-tank missile. In addition to anti-tank missiles, the French Army chose to arm their Alouette IIs with machine guns, while the French Navy outfitted theirs with aerial torpedoes to conduct anti-submarine warfare (ASW) duties.
