| An anti-submarine weapon is any one of a range of devices that are intended to act against a submarine, and its crew, to destroy (sink) the vessel or to destroy or reduce its capability as a weapon of war. An anti-submarine weapon can be integrated with an anti-submarine warfare (ASW) system, such as the US Navy Tactical Data System (NTDS), that controls air, land and sea-based weapon system threat detection and target acquisition. However, in its simplest sense it is a projectile, missile or bomb that is optimized to destroy submarines. |
