Mine countermeasures vessel

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.[1] The term MCMV is also applied collectively to minehunters and minesweepers.

Bedok-class mine countermeasures vessel

The Bedok-class are mine countermeasures vessels (MCMVs) 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 194 Squadron of the RSN.

HMS Atherstone (M38)

HMS Atherstone was a Hunt-class mine countermeasures vessel of the Royal Navy, the third ship to bear the name. She was built by Vosper Thornycroft shipbuilders at Woolston, Southampton. She was launched on 1 March 1986 by Mrs Amy Jarvis, the wife of Mr Pat Jarvis, CB, the Deputy Controller of the Navy at the Ministry of Defence, and commissioned on 17 January 1987,. She was the tenth ship of her class.

HMS Berkeley (M40)

HMS Berkeley was a Hunt-class mine countermeasures vessel of the British Royal Navy.

She was the twelfth of the thirteen Hunt-class vessels, and was built by Vosper Thorneycroft shipbuilders at Woolston, Southampton. She was launched on 3 December 1986 by Lady Gerken, the wife of Vice Admiral Sir Robert Gerken, former Flag Officer Plymouth.Berkeley was commissioned on 14 January 1988, and after sea trials, was assigned to the 1st Mine Countermeasures Squadron based at Rosyth, Scotland. She took part in mine clearance operations in the Persian Gulf following the 1st Gulf War and later was involved in fishery protection duties in UK waters.She was sold to the Greek Navy in 2001 and renamed Kallisto.

HMS Bicester (M36)

HMS Bicester was a Hunt-class mine countermeasures vessel of the Royal Navy. She was sold to the Greek Navy in 2001 as Europa.

HMS Brecon (M29)

HMS Brecon was a Hunt-class mine countermeasures vessel that served with the Royal Navy. Her pennant number was M29.

HMS Brocklesby (M33)

HMS Brocklesby is a Hunt-class mine countermeasures vessel of the British Royal Navy.

HMS Cattistock (M31)

HMS Cattistock, the third ship of this name, is a Hunt-class mine countermeasures vessel of the Royal Navy. She was launched in 1981 and commissioned on 5 March 1982, the third ship of her class.

HMS Chiddingfold (M37)

HMS Chiddingfold is a Hunt-class mine countermeasures vessel of the British Royal Navy.

She was launched in October 1983 by her sponsor, Lady Anne Kennon, and formally entered the service of the Royal Navy in October 1984. Chiddingfold is a minehunter, and her purpose is to find and destroy mines, not only in a time of war but also in peacetime. There are about a quarter of a million mines still active from the Second World War alone and they pose a major threat to both military and civilian ships. Chiddingfold is able to enter some types of minefields without the mines detonating. This is because she is made of glass-reinforced plastic and all fixtures within the ship are made of non-ferrous metals, keeping the ship's magnetic signature to the bare minimum.

HMS Cordella

HMS Cordella was a Royal Navy auxiliary mine countermeasures vessel that served during the Falklands War as part of 11th MCM Squadron.

HMS Dulverton (M35)

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.

Thales was awarded the prime contractorship to upgrade the vessels with a technologically advanced minehunting system, including the hull-mounted Sonar 2193 system, propulsion, command and control systems, and mine disposal systems. The ship entered service with the Lithuanian navy in 2011 as Kuršis.

HMS Hurworth (M39)

HMS Hurworth is a Hunt-class mine countermeasures vessel of the British Royal Navy.

On 2 March 2009, she was the centrepiece of the festivities to mark the 800th anniversary of the granting of a freedom charter by King John to Great Yarmouth.

HMS Ledbury (M30)

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 Middleton (M34)

HMS Middleton is a Hunt-class mine countermeasures vessel of the British Royal Navy. She forms part of the Second Mine Countermeasures Squadron based in Portsmouth.

The ship was launched by Lord and Lady Blaker in 1983: Lady Blaker remains the patron of the ship.

Hunt-class mine countermeasures vessel

The Hunt class is a class of thirteen mine countermeasure vessels of the Royal Navy. As built, they combined the separate roles of the traditional minesweeper and that of the active minehunter in one hull, but later modifications saw the removal of mine-sweeping equipment. They have a secondary role as offshore patrol vessels.

Koster-class mine countermeasures vessel

The Koster class is a class of five mine-countermeasure vessels currently in use by the Swedish Navy. Built between 1982 and 1993 as part of the seven-strong Landsort-class mine countermeasures vessels, the last five ships of the class were given a comprehensive midlife upgrade between 2007 and 2010, which resulted in HMS Koster becoming the lead ship of the newly upgraded class of MCMVs. After the upgrade, the Swedish Navy expects that it will serve on for another 15 to 20 years. An identifying feature of the Koster class is the fire control radar on top of the bridge.

Landsort-class mine countermeasures vessel

The Landsort class mine countermeasures vessel is built by Swedish shipbuilding company, Kockums (formerly Karlskronavarvet) for the Swedish Navy and the Republic of Singapore Navy (RSN).


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).

Sauda-class mine countermeasures vessel

The Sauda class was a class of nine minesweepers and one minehunter in service for the Royal Norwegian Navy from 1953 to 1996. The class was designed at Sparkman & Stephens Inc., New York City, as an improvement of the NYMS class (Norwegian Yard Mine Sweepers). Five of the vessels were built in the United States, three were built at Westermoen Båtbyggeri og Mek Verksted in Mandal, one at Skaalurens Skibsbyggeri in Rosendal and one at De Forenede Båtbyggerier in Risør. The class was fully financed by the US government as a part of the Military Assistance Program (MAP).

Most of the vessels were named after Norwegian rivers:Sira, Tana, Alta, Ogna, Vosso, Glomma, Tista, Kvina and Utla. Sauda is however a town, not a river. Alta is the only vessel still in existence. She is a museum vessel owned by the Royal Norwegian Navy Museum but maintained and sailed by a dedicated friendship association. Some of the vessels were in service in the United States Navy and the Royal Belgian Navy before entering Norwegian service.

Styrsö-class mine countermeasures vessel

The Styrsö class is a Swedish mine countermeasures vessel built from glass fiber. Among its intended missions are mine detection, mine hunting and patrolling. The ships are named after islands from four different archipelagos of Sweden. In 2004 HMS Spårö and HMS Sturkö were modernised, pulling out some of their capability for traditional mine clearance in favour of extended human dive support, the modified vessels are occasionally called Spårö class.
