Limbo, a three-barreled mortar similar to the earlier Squid and Hedgehog that it superseded, was developed by the Admiralty Underwater Weapons Establishment in the 1950s. Squid was loaded manually, which was difficult on a pitching deck in heavy seas with no protection from the elements; in contrast Limbo was loaded and fired automatically, with all the crew under cover. It was widely fitted on the quarterdeck of Royal Navy escort ships on a mounting stabilised for pitch and roll from 1955 to the mid–1980s. Australian built versions of the Daring class destroyer all carried Limbo as did the Australian River class destroyer escort. Limbo was also widely employed by the Royal Canadian Navy, being incorporated into all destroyer designs from the late 1950s to the early 1970s, including the St. Laurent, Restigouche, Mackenzie, Annapolis and Iroquois classes.The firing distance of the mortars was controlled by opening gas vents; rounds could be fired from 400 yards to a maximum of 1,000 yards (366 and 910 m). The weapon was linked to the sonar system of the ship, firing on command when the target was in range. The rounds were projected so that they fell in a triangular pattern around the target. Limbo could fire in any direction around the ship and is reported to have been very accurate. The weapon was used in the 1982 Falklands War, and remained in service in the Royal Navy and Commonwealth navies until the 1990s when it was superseded by the Mark 44 torpedo. A surviving system is preserved at Explosion! Museum of Naval Firepower in Gosport, Hampshire."@en }
