HMS Bassingham was one of 93 ships of the Ham-class of inshore minesweepers, of which HMS Inglesham (M2601) was the first. Their names were all chosen from villages ending in -ham. The minesweeper was named after Bassingham in Lincolnshire. She was built by Vospers Ltd. of Portsmouth, which later became Vosper-Thorneycroft and was commissioned in October 1953. She displaced 164 tons fully laden and was armed with one 40 mm Bofors gun.
