HMCS Nipigon (J154) was a Bangor-class minesweeper serving in the Royal Canadian Navy during World War II. Built to a British design, the ship was larger than her diesel-engined counterparts, measuring 180 feet (54.9 meters) in length overall with a beam of 28 feet 6 inches (8.7 meters) and a draught of 9 feet 9 inches (3.0 meters). She displaced approximately 672 long tons (683 tonnes) and had a complement of 6 officers and 77 enlisted personnel. Power was provided by two vertical triple-expansion steam engines, each driving a single shaft, fueled by two Admiralty three-drum boilers, producing 2,400 indicated horsepower and enabling a maximum speed of 16.5 knots (30.6 km/h). Armament on Nipigon included a single 4-inch (102 mm)/40 caliber Mk IV gun mounted forward, along with one QF 2-pounder Mark VIII and two single-mounted QF 20 mm Oerlikon guns for anti-aircraft defense. She was also equipped with 40 depth charges, facilitating her role as a convoy escort and minesweeper. Laid down on 4 July 1940 by Dufferin Shipbuilding Co. in Toronto, Nipigon was launched on 1 October 1940 and commissioned on 11 August 1941 at Toronto, bearing the pennant number J154. After commissioning, she served with Sydney Force, later joining the Western Local Escort Force, Halifax Force, and Newfoundland Force. In June 1943, she was assigned to Escort Group W-1. During her wartime service, she participated in the Battle of the Atlantic and the Battle of the St. Lawrence, performing convoy escort duties and minesweeping operations until she was paid off on 13 October 1945. Postwar, Nipigon was placed in reserve at Sorel, Quebec, and eventually reactivated in 1952, reclassified as a coastal escort with the new pennant number 188, though she was never recommissioned. In 1957, she was sold to the Turkish Naval Forces and renamed Bafra, serving until 1972. The vessel was eventually broken up in Turkey in 1972, marking the end of her maritime service.
