The Ton class were coastal minesweepers built in the 1950s for the Royal Navy, but also used by other navies such as the South African Navy and the Royal Australian Navy. They were intended to meet the threat of seabed mines laid in shallow coastal waters, rivers, ports and harbours, a task for which the existing ocean-going minesweepers of the Algerine-class were not suited.
HMS Dittisham was one of 93 ships of the Ham-class of inshore minesweepers built for the British Royal Navy. Their names were all chosen from villages ending in -ham. The minesweeper was named after Dittisham in Devon.
HMS Mersham was a Ham-class minesweeper of the Royal Navy. All ships of the class were named after villages ending in -ham. The minesweeper was named after Mersham in Kent. Constructed at Appledore, in Devon, Mersham was launched in April 1954 and completed in January 1955. In April 1955, the ship was transferred to the French Navy and in French service, was known by its pennant number, M773, until it was renamed Violette in 1964. Throughout the 1950s and early 1960s, the vessel undertook minesweeping duties from Brest in Brittany, before being laid up in 1965. In 1974, the ship was transferred to the Gendarmerie and undertook patrol duties until finally being decommissioned in 1987.
HMS Puttenham(M2784) was a Ham-class inshore minesweeper of the Royal Navy. She was launched in 1956 and entered service in 1958. The 93 ships of the Ham class had names chosen from villages ending in -ham. The minesweeper was named after Puttenham.
HMCS Miramichi 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.
HMCS Comox was a Bay-class minesweeper built for the Royal Canadian Navy during the Cold War. The vessel was named for Comox Harbour, a bay in British Columbia. The minesweeper was later transferred to the Turkish Navy where she was renamed Tirebolu and served until 1996.
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
HMS Fittleton, originally named HMS Curzon, was a wooden-hulled Ton-class minesweeper of the Royal Navy which spent most of her career in the Royal Naval Reserve. She was sunk in a collision with HMS Mermaid on 20 September 1976 whilst en route to Hamburg for an official visit. Twelve naval service personnel lost their lives, making this the worst peacetime accident involving the Royal Naval Reserve.

The vessel was used as a test bed in the mid-1960s for new propulsion technologies. Shoulton was among the vessels assigned to salvage operations following the Aer Lingus Flight 712 crash off Rosslare. In 1977, Shoulton took part in the naval review marking the Silver Jubilee of Elizabeth II and was paid off on 23 November 1979.
