ASROC is the U.S. Navy's acronym for Anti-Submarine ROCket. It was a ship-to-ship weapon. An anti-submarine missile is a standoff weapon including a rocket designed to rapidly deliver an explosive warhead or homing torpedo from the launch platform to the vicinity of a submarine. It was a surface ship's method for a far distant delivery of a torpedo beyond its normal range, or of a nuclear depth-charge to an enemy ship, with the thinking that because of the greater distance and detonation of the nuke that the firing ship would be safe.
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; but shipboard SONAR was unable to maintain contact with the 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. During the cold war, rockets were developed to provide greater range with reduced recoil. Some rockets carry homing torpedoes to provide terminal guidance for the warhead.
