HMCS Nipigon was an Annapolis-class destroyer that served in the Royal Canadian Navy and later the Canadian Forces from 1964 until her decommissioning in 1998. Named after the Nipigon River in Ontario, she measured 366 feet (112 meters) in length, with a beam of 42 feet (13 meters) and a draught of 13 feet 2 inches (4.01 meters). Her displacement was approximately 2,400 tonnes, and she carried a crew of around 228 personnel. Propelled by two Babcock & Wilcox boilers connected to two-shaft English-Electric geared steam turbines, Nipigon could reach a maximum speed of 28 knots. Initially, her armament comprised two 3-inch (76 mm)/50 caliber dual-purpose guns in a single Mk 33 mount forward, capable of firing 45-50 rounds per minute. As part of her anti-submarine capabilities, she was equipped with a Mk 10 Limbo mortar, a British-designed three-barrel system capable of launching shells at targets 400 to 1,000 yards away, and a Mk.4 homing torpedo thrower. She also featured radar systems including SPS-12 air search, SPS-10B surface search, and Sperry Mk.2 navigation radars, complemented by sonar equipment such as the SQS series for below-surface detection. Her design incorporated a helicopter hangar and "Beartrap" haul-down device, allowing her to operate a CH-124 Sea King helicopter, enhancing her anti-submarine warfare (ASW) capabilities. Throughout her service life, Nipigon underwent significant upgrades, including the DELEX refit in the 1980s, which modernized her sensors, radars, fire control systems, and replaced her VDS with the Canadian Tactical Towed Array Sensor (CANTASS). Her operational history includes escorting the royal yacht HMY Britannia in 1964, participating in NATO exercises, and conducting search and rescue missions, such as recovering survivors from the sinking Ocean Ranger platform in 1982. She was also involved in the Turbot War in 1995, intercepting illegal fishing vessels. After her decommissioning in 1998, Nipigon was sold and sunk as an artificial reef off Quebec in 2003, marking the end of her distinguished service in the Canadian Navy.
