HMCS Miramichi (hull number MCB 163) was a Bay-class minesweeper constructed for the Royal Canadian Navy during the Cold War era. Laid down on 2 February 1956 by Victoria Machinery Depot in Victoria, British Columbia, the vessel was launched on 22 February 1957 and commissioned later that year on 29 October. This ship was named after a bay in New Brunswick and served primarily on Canada’s West Coast. The Miramichi had a displacement of approximately 390 long tons (400 tonnes) at standard load, increasing to 412 long tons (419 tonnes) at deep load. It measured 152 feet (46 meters) in length, with a beam of 28 feet (8.5 meters) and a draught of 8 feet (2.4 meters). The vessel's complement consisted of 38 officers and ratings. Its construction featured wood planking and aluminum framing, a design choice typical of the Bay class, similar to the Ton-class minesweepers, to facilitate minesweeping operations. Powered by two GM 12-cylinder diesel engines driving two shafts, HMCS Miramichi generated 2,400 brake horsepower, allowing a maximum speed of 16 knots (approximately 30 km/h). The ship had a range of 3,290 nautical miles (around 6,090 km) at a cruising speed of 12 knots (about 22 km/h). Its armament was modest, comprising a single 40 mm Bofors gun, complemented by minesweeping gear necessary for its primary role. Initially, Miramichi was assigned to Training Group Pacific, where it served mainly as a training vessel on the West Coast of Canada. In 1972, the class designation was changed from minesweepers to patrol escorts, reflecting a broader role within the navy. The vessel continued in service until it was decommissioned on 16 December 1998, with some sources indicating it was paid off in October 1998. The ultimate fate of HMCS Miramichi remains unknown. Its long service life underscores its significance as part of Canada's Cold War naval fleet, primarily contributing to training and patrol operations along the Pacific coast.
