Design and description

The Bay class were designed and ordered as replacements for the Second World War-era minesweepers that the Royal Canadian Navy operated at the time. Similar to the Ton-class minesweeper, they were constructed of wood planking and aluminum framing.[3][4]

Displacing 390 long tons (400 t) standard at 412 long tons (419 t) at deep load, the minesweepers were 152 ft (46 m) long with a beam of 28 ft (8.5 m) and a draught of 8 ft (2.4 m).[3][4] They had a complement of 38 officers and ratings.[3][note 2]

The Bay-class minesweepers were powered by two GM 12-cylinder diesel engines driving two shafts creating 2,400 brake horsepower (1,800 kW). This gave the ships a maximum speed of 16 knots (30 km/h; 18 mph) and a range of 3,290 nautical miles (6,090 km; 3,790 mi) at 12 knots (22 km/h; 14 mph).[4][5] The ships were armed with one 40 mm Bofors gun and were equipped with minesweeping gear.[3][4]

Service history

Miramichi was laid down on 13 June 1952 by Saint John Dry Dock and Shipbuilding Co. at Saint John, New Brunswick and was launched on 4 May 1954. The vessel was commissioned into the Royal Canadian Navy on 30 July 1954 at Saint John.[6]

After commissioning, Miramichi spent the next two months in service before being paid off on 1 October 1954. She was transferred to France under the NATO Mutual Aid Agreement on 9 October 1954.[6][7] The ship commissioned into the French Navy on 13 November 1954.[8] The vessel was eventually replaced in the Royal Canadian Navy by Miramichi (MCB 163) of the same class.[6] Renamed La Lorientaise the ship served as a minesweeper until 1973 when she had air conditioning installed for use as an overseas territories patrol vessel in the Pacific.[8] She served until 1984.[3][note 3] The vessel was stricken in 1986 and broken up at Papeete, Tahiti.[2]
