Air-dropped anti-submarine torpedoes preceded the postwar helicopter, with Avenger aircraft in the Second World War cited as an example. Whether a helicopter used depth charges or a lightweight torpedo depended on its country's inventory and the period. Lightweight torpedoes gave helicopters an effective means of attacking submarines. Early low and slow attack profiles could leave helicopters vulnerable to return fire, although the opportunity for a submarine missile shot depended on the stage of the encounter.

Helicopter weapons varied by navy and date, while lightweight torpedoes connected aerial submarine detection with an effective attack.
