HMS Mariner was an Algerine-class minesweeper powered by reciprocating steam engines, constructed during the Second World War. Originally ordered as HMCS Kincardine for the Royal Canadian Navy in July 1942, the vessel was built by the Port Arthur Shipbuilding Company in Ontario. Laid down on August 26, 1942, and launched on May 9, 1944, she was transferred to the Royal Navy upon completion as part of an exchange for Castle-class corvettes, and was commissioned as HMS Mariner on May 23, 1944. The ship measured 225 feet (68.6 meters) in length overall, with a beam of 35 feet 6 inches (10.8 meters) and a draught of 12 feet 3 inches (3.7 meters). Displacing approximately 1,010 to 1,030 long tons at standard load and up to 1,325 long tons at deep load, HMS Mariner had a complement of about 85 officers and ratings. Her propulsion system consisted of two vertical triple-expansion steam engines, each driving a single shaft, fueled by two Admiralty three-drum boilers. This configuration produced 2,400 indicated horsepower, enabling the vessel to reach a maximum speed of 16.5 knots. She carried a fuel oil capacity of 660 long tons, offering a range of 5,000 nautical miles at 10 knots. Armament on HMS Mariner included a QF 4-inch (102 mm) Mk V anti-aircraft gun and four twin mounts for Oerlikon 20 mm cannons, though shortages sometimes resulted in mixed armament configurations. By 1944, single Bofors 40 mm mounts began replacing some twin 20 mm guns. The ship was also equipped with four depth charge throwers and two rails, reflecting her role in minesweeping and anti-submarine warfare. During her service, HMS Mariner participated in patrols, notably in the North Sea in 1954 as a fishery protection vessel, inspecting trawlers and providing assistance. In 1958, she was sold to the Burmese Navy, reactivated at HM Dockyard Sheerness, and renamed Yang Myo Aung. She was converted into a minelayer, capable of carrying eight mines on each side, and served in the Burmese Navy until 1982. Her career highlights her versatility and the importance of Algerine-class minesweepers in mid-20th-century maritime operations.
