Description


AT-2 air-launched torpedo

The AT-2 is a heavyweight air launched torpedo of Soviet origin. It was developed in the early 1960's for use against submarines. In order to achieve the requested range, speed and detection range a large torpedo was required. This makes the AT-2 one of the few air launched heavyweight torpedoes developed during the Cold War. The majority of air-launched torpedoes are much smaller and only a quarter of the weight.

Design of the AT-2 is conventional with electric propulsion and acoustic homing. The AT-2 is carried by fixed wing anti-submarine warfare aircraft, not by helicopters. The AT-2U is a modified AT-2 for use by the large Metel ASW rocket system. Existing AT-2 and AT-2U were modernized to AT-2M and AT-2UM standard. This may either be a life extension program, or and upgrade with improved performance.
