Anti-submarine missile
An anti-submarine missile is a standoff anti-submarine weapon. They include a missile or rocket designed to rapidly deliver an explosive warhead or homing torpedo, from the launch platform to the vicinity of a submarine.

History
Depth charges were the earliest weapons designed for use by ships against submerged submarines. These explosives were initially dropped as the ship moved over the presumed location of a submarine. Before World War II, shipboard sonar was unable to maintain contact with a submarine at close range.
Various mortar-type projectors, including hedgehog and squid, were devised during World War II to allow a ship to maintain sonar contact while lobbing explosive charges toward the submarine.[1]
During the Cold War, missiles were developed to provide greater range with reduced recoil. Some missiles and rockets carry homing torpedoes to provide terminal guidance for the warhead.[2]
