A minehunter is a naval vessel that seeks, detects, and destroys individual naval mines. Minesweepers, on the other hand, clear mined areas as a whole, without prior detection of mines. A vessel that combines both of these roles is known as a mine countermeasures vessel (MCMV).
The Sandown class is a class of fifteen minehunters built primarily for the Royal Navy by Vosper Thornycroft. The Sandown class also serve with the Royal Saudi Navy, the Estonian Navy, and the Ukrainian Navy. The first vessel was commissioned into Royal Navy service on 9 June 1989 and all the British ships were named after coastal towns and cities. Although the class had a primary mine countermeasures role, they have had a secondary role as offshore patrol vessels. As of early 2024, only one vessel of the class remains in active service with the Royal Navy.
HMS Kirkliston (M1157) was a Ton-class minesweeper of the Royal Navy, built by Harland and Wolff and launched on 18 February 1954. In a brief episode from 1956 to 1960 she was temporarily renamed HMS Kilmorey and was assigned to the Ulster division Royal Naval Reserve (RNR).
HMS Bangor is a Sandown-class minehunter commissioned by the Royal Navy in 2000. Designed to hunt naval mines in depths of up to 200 m (660 ft) using the Sonar 2093 Variable Depth Sonar (VDS) meaning that she can conduct mine clearance operations throughout the continental shelf. She is named after the Northern Ireland seaside city of the same name, and the second Royal Navy vessel to bear the name. As of January 2024, she was the last vessel of her class in active Royal Navy service.
The Osprey class are a series of coastal minehunters designed to find, classify, and destroy moored and bottom naval mines from vital waterways.
A mine countermeasures vessel or MCMV is a type of naval ship designed for the location of and destruction of naval mines which combines the role of a minesweeper and minehunter in one hull. The term MCMV is also applied collectively to minehunters and minesweepers.
The Tripartite class is a class of minehunters developed from an agreement between the navies of Belgium, France and the Netherlands. A total of 35 ships were constructed for the three navies. The class was constructed in the 1980s–1990s in all three countries, using a mix of minehunting, electrical and propulsion systems from the three member nations. In France, where they are known as the Éridan class they are primarily used as minehunters, but have been used for minesweeping and ammunition transport in Belgium and the Netherlands, where the Tripartites are known as the Alkmaar class.
HMS Ledbury, the second ship of the name, is a Hunt-class mine countermeasures vessel of the Royal Navy. She was launched in December 1979 and commissioned on 11 June 1981, the second ship of her class. She cost £65 million at time of building, which was at the time the most expensive cost-per-metre for any class of ship built by the Royal Navy. Most of this cost went into the research and development of Ledbury's glass reinforced plastic hull.
HMS Pembroke was a Sandown-class minehunter of the Royal Navy (RN), the second ship launched from the class' second batch, with several improvements over the first five built.
HMSInverness(M102) was a Sandown-class minehunter of the Royal Navy. She was decommissioned by the Royal Navy in 2005, and in 2008 became EMLSakala(M314) of the Estonian Navy.
HMS Brocklesby is a Hunt-class mine countermeasures vessel of the British Royal Navy, her primary purpose is to find and neutralise sea mines using a combination of; Sonar, Mine Clearance Divers and the Seafox remotely operated vehicle (ROV). The class are the largest warships of glass-reinforced plastic (GRP) construction, which gives the vessels a low magnetic signature. In addition to her mine countermeasures activities, Brocklesby acts as an offshore patrol vessel, undertaking coastal patrol and fisheries protection duties.
HMS Middleton is a Hunt-class mine countermeasures vessel of the British Royal Navy. As of 2021, she forms part of 9th Mine Countermeasures Squadron operating out of HMS Jufair in Bahrain.
HMS Cottesmore was a Hunt-class mine countermeasures vessel of the British Royal Navy, launched in 1982 and converted in 1997 into a patrol vessel. The ship was declared surplus to requirement and put on the MoD list for disposal in 2004. In 2008 she was bought by Lithuania, along with Dulverton.
HMS Berkeley was a Hunt-class mine countermeasures vessel of the British Royal Navy. She was sold to the Hellenic Navy in 2001 and was commissioned as HS Kallisto. On 27 October 2020, she was cut in two in a collision with a container ship.
HMS Dulverton was a Hunt-class mine countermeasures vessel of the British Royal Navy, launched in 1982 and converted in 1997 into a patrol vessel. The ship was declared surplus to requirement and put on the MoD list for disposal in 2004. In 2008 she was bought by Lithuania, along with Cottesmore.
Avenger-class mine countermeasures ships are a class of 14 ships constructed for the United States Navy from 1987 to 1994, designed to clear mines from vital waterways. The ships have the hull designator MCM.
The Bedok class are mine countermeasures vessels of the Republic of Singapore Navy (RSN). They play an important role in the maritime security of Singapore, ensuring that the Singapore Strait and the sea lanes surrounding Singapore remain mine-free and open to international shipping. It is estimated that closure of Singapore's ports would result in direct trade losses amounting to more than US$1.2 billion daily, posing a serious threat to Singapore's economy. The four ships form the Sixth Flotilla of the RSN.
The Netherlands and Belgium are doing a joint procurement for the replacements of the Tripartite-class/Alkmaar-class minehunters. Each of the two countries is procuring six new mine countermeasure (MCM) vessels, which makes for a total of 12 MCM ships. The new MCM ships, developed by Naval Group, will include a range of unmanned systems including unmanned surface, aerial and underwater vehicles alongside towed sonars and mine identification and neutralization remotely operated vehicles.
