HMCS Miramichi (MCB 150)

HMCS Miramichi (hull number MCB 150) was a Bay-class minesweeper that served in the Royal Canadian Navy and the French Navy. She was named Miramichi Bay, located at the mouth of the Miramichi River in New Brunswick. Entering service in 1954, the vessel served in the Royal Canadian Navy for only a few months before transferring to the French Navy. Renamed La Lorientaise, the ship was used as a minesweeper before converting to a patrol vessel in 1973. The ship was discarded in 1986.

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.

Displacing 390 LT standard at 412 LT at deep load, the minesweepers were 152 ft long with a beam of 28 ft and a draught of 8 ft. They had a complement of 38 officers and ratings.

The Bay-class minesweepers were powered by two GM 12-cylinder diesel engines driving two shafts creating 2400 bhp. This gave the ships a maximum speed of 16 kn and a range of 3290 nmi at 12 kn. The ships were armed with one 40 mm Bofors gun and were equipped with minesweeping gear.
