HMS Bangor was a Bangor-class minesweeper of the Royal Navy, built at the Harland & Wolff shipyard in Govan, Scotland. As the lead vessel of her class, she was one of the diesel-engined variants, designed for minesweeping duties during World War II. The vessel was ordered on 12 July 1939, laid down on 19 September 1939, launched on 23 May 1940, and commissioned into service on 7 November 1940. She was named after the seaside town of Bangor in Northern Ireland. Her service began shortly after commissioning, with her assigned to the 9th Minesweeping Flotilla (MSF) based at Scapa Flow on 18 November 1940. Early in her service, she was involved in various operations, including an incident on 12 February 1941 in the Moray Firth where she was bombed but sustained no damage, although her wireless telegraphy was knocked out. The flotilla later transferred to the Portsmouth Command in March 1941, and Bangor participated in defensive actions, including an engagement on 19 May 1941 against attacking German aircraft, where she and other vessels claimed to damage two Messerschmitt Bf 109 fighters. A notable operation was her involvement in Operation Jubilee, the raid on Dieppe in August 1942. Bangor’s role was to assist in sweeping for mines in the area believed to be mined, which she accomplished successfully under challenging conditions. She also took part in the D-Day landings in June 1944 as part of Operation Neptune, where her flotilla was tasked with sweeping channels for the invasion. During this operation, she encountered heavy German fire while attempting to clear mines near Cherbourg, which forced her to withdraw after only three miles of sweeping. After the war, Bangor conducted minesweeping operations in Norway in May 1945. In June 1945, she was loaned to the Royal Norwegian Navy, which purchased her in October 1946 and renamed her Glomma. She served in the Norwegian Navy until she was stricken in December 1961 and subsequently broken up. Bangor’s service history highlights her significant role in key wartime operations, including mine clearance, defensive actions, and supporting major amphibious assaults during World War II.
