[1] Design and development of the missile began in 1983 when Goodyear Aerospace was contracted by the U.S. Navy to develop a ship-launched anti-submarine missile compatible with the new Mark 41 vertical launching system (VLS).
The development of the VLS ASROC underwent many delays, and it was not deployed on any ships until 1993.
During this development, Goodyear Aerospace was bought by Loral Corporation in 1986, and this defense division was in turn purchased by Lockheed Martin in 1995.
It carries a lightweight Mark 46 homing torpedo that is dropped from the rocket at a precalculated point on its trajectory, and then parachuted into the sea.
It is 4.5 meters (15 ft) in length, with a firing range of about 11.8 nm or 22 kilometers (24,000 yd).
