Design
The Yevgenya class are small minesweepers built for inshore work. The hulls are constructed of glass-reinforced plastic. As built they have a standard displacement of 89.9 tonnes (88.5 long tons ), 91 tonnes (90 long tons) normally , 93.0 tonnes (91.5 long tons) at full load and maximum 96 tonnes (94 long tons). The Yevegenya class measures 26.13 metres (85 ft 9 in) long overall, 23 metres (75 ft 6 in) between perpendiculars and 24.16 metres (79 ft 3 in) at the waterline with an extreme beam of 5.9 metres (19 ft 4 in) and 5.4 metres (17 ft 9 in) at the waterline. The vessel has a normal draught of 1.35 metres (4 ft 5 in) and 1.38 metres (4 ft 6 in) fully load.
As built, the minesweepers are powered by two diesel engines turning two propeller shafts creating 630 kilowatts (850 bhp ). This gives the ships a maximum speed of 12 knots (22 km/h; 14 mph) and a range of 300 nmi (560 km; 350 mi) at 10 knots (19 km/h; 12 mph). They carry 91 tonnes (90 long tons) of diesel fuel.
The vessels have twin-mounted 14.5 mm (0.57 in) machine guns. They are equipped with MT-34, AT-2, SEMT-3, Neva and GKT-3 sweeps. The minesweepers mount MG-7 sonar. They have a complement of 10.
The Delfinen-class submarines were the first class of submarines constructed for the Royal Danish Navy following World War II. They were designed and built within Denmark, with first three boats of the class financed by Denmark. The fourth was financed by the United States under the Cost Share program. Constructed between 1956 and 1963, the class comprising four submarines entered service in 1961 and the last taken out of service in 1990. Replaced by the Norwegian Kobben class, three of them were scrapped while a fourth was converted into a museum ship and remains on display at the Aalborg Maritime Museum.
The Vidar-class minelayers consists of the two ships, HNoMS Vidar and HNoMS Vale built by Mjellem & Karlsen in Bergen for the Royal Norwegian Navy in 1977 and 1978. Used as multi-role ships, the Vidar class were tasked with minelaying, personnel/cargo transport, fisheries protection, torpedo-recovery ships and as anti-submarine warfare escorts in Norwegian service. In 2003, Vale was transferred to the Latvian Navy via donation and renamed Virsaitis and used as a flagship and tender to patrol craft. In 2006, Vidar was transferred to the Lithuanian Navy and renamed Jotvingis and served as flagship and tender to mine countermeasures craft. Both vessels had their ASW equipment removed upon transfer.
The Claud Jones-class destroyer escorts were four destroyer escorts built for the United States Navy in the late 1950s. These ships were a diesel-powered version of the earlier Dealey class and were designed with the aim of producing a cheaper ship suitable for rapid production in wartime. These ships also had reduced armament and speed compared to their predecessors. They were not seen as effective anti-submarine warfare vessels by the United States Navy and were sold after only 15 years service to the Indonesian Navy.
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.
HMCS Chaleur was a Bay-class minesweeper that served in the Royal Canadian Navy for three and a half months in 1954 before being sold to the French Navy to become La Dieppoise. The ship was named for Chaleur Bay, located between Quebec and New Brunswick. Her name was given to her replacement, Chaleur (MCB 164). As La Dieppoise, the vessel served as a coastal patrol vessel in the France's Pacific Ocean territories. The ship was taken out of service in 1987.
The Kuha-class minesweepers is a series of six inshore minesweepers of the Finnish Navy. The ships were constructed in 1974–1975. All the vessels of the class were modified and modernized in the late 1990s, including a lengthening of the hull. Two of the class were withdrawn from service in 2012. The rest of the class will be retired with the entry into service of the Katanpää-class mine countermeasure vessels.
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.
The Sjöormen class was a class of submarines built for the Swedish Navy in the late 1960s. They had a teardrop hull shape and were capable of diving to 150 metres (490 ft). At the time of their deployment they were regarded as one of the most advanced non-nuclear submarine-classes in the world, incorporating many new features including x-rudder and anechoic tiles. Both speed and underwater endurance was at this time very high for a conventional submarine. The submarines were retired by Sweden in the early 1990s. In the late 1990s, four submarines were acquired by the Republic of Singapore Navy (RSN) and relaunched as the Challenger class following modernisation and tropicalisation.
The Poti class was the NATO reporting name for a group of anti-submarine warfare (ASW) corvettes built for the Soviet Navy. The Soviet designation was Project 204 small anti-submarine ships. These ships were the first Soviet warships powered by gas turbine engines; two propellers were mounted in tunnels to give a very shallow draught. A twin 57 mm (2 in) gun mounting provided self-defence. Three ships of the class were exported to Romania and six to Bulgaria during the Cold War. By 2008, all ships of the class were no longer extant.
Project 1252 'Izmrud' were a group of three minesweepers built for the Soviet Navy in the late 1960s. The ships were a glass-reinforced plastic (GRP)-hulled version of the preceding wooden-hulled Vanya class. They were intended to be a prototype of an advanced design, instead the Soviet Navy returned to wooden-hulled minesweeper construction with the following Sonya class. Of the three minesweepers, one was lost in an explosion in 1989 and the fate of the other two is unknown.
The Mendoza class were a series of three destroyers built in the United Kingdom for the Argentine Navy in the 1920s. They were the first part of the Argentine re-armament programme of the 1920s. Construction began in 1927 and all three were commissioned in 1929. All three destroyers were converted to anti-aircraft escorts in 1958 and remained in service until 1962 when they were discarded.
The Khamronsin-class corvettes are three corvettes constructed for the Royal Thai Navy in the late 1980s. Based on a British design, all three ships were built in Thailand. A fourth vessel, constructed to a modified design, was built for the Thai Police and was the first to enter service in 1992. The three Khamrosin-class corvettes commissioned in 1992 and remain in service.
Drazki is a Wielingen-class frigate of the Bulgarian Navy. Originally constructed for and operated by the Belgian Naval Component as Wandelaar, the frigate was designed as a platform capable of multiple uses as an escort during the Cold War in the North Sea and English Channel. The vessel uses weapons and sensor technology from NATO counterparts, which was one of the reasons the ship was acquired by the Bulgarian Navy in 2004. The frigate is currently in active service.
The EDIC or Engin de débarquement d'infanterie et de chars are large landing craft that operate in the French Navy, Lebanese Navy, Senegalese Navy, and Madagascar Navy. EDICs have the typical landing craft utility design with a bow ramp and have a large aft superstructure compared to the derivative CDIC. The EDIC vessels were constructed in three groups, the first were launched in 1958, the second in 1967–1969 and the third in 1987. A sub class, called the Engin de débarquement ateliers or EDA was constructed between the first and second groups but were fitted out as repair craft. In French service, they predominantly were used in the French Pacific territories.
HMCS Chaleur was a Bay-class minesweeper that served in the Royal Canadian Navy during the Cold War. Entering service in 1957, the minesweeper was used mainly as a training ship on the West Coast of Canada. The vessel was discarded in 1998 and broken up in 1999.
HMCS Chignecto was a Bay-class minesweeper that served in the Royal Canadian Navy during the Cold War. The ship entered service in 1953 and in 1954, was transferred to the French Navy and renamed La Bayonnaise. Serving as a minesweeper until 1973, the ship became a territorial patrol ship and remained in service until 1976. La Bayonnaise was broken up for scrap in 1977.
HMCS Chignecto was a Bay-class minesweeper that served in the Royal Canadian Navy during the Cold War. Entering service in 1957, the minesweeper was used primarily as a training vessel on the Pacific coast of Canada. Discarded in 1998, the ship was broken up in 1999.
HMCS Cowichan was a Bay-class minesweeper that served in the Royal Canadian Navy during the Cold War. The minesweeper entered service in 1953 and was transferred to the French Navy in 1954. Renamed La Malouine, the ship was converted to a territorial patrol vessel in 1973 and remained in service until 1977. La Malouine was sunk as a target ship in 1985.
HMCS Fundy was a Bay-class minesweeper that was constructed for the Royal Canadian Navy during the Cold War. Entering service in 1956, the vessel was used as a training ship on the West Coast of Canada for the majority of her career. Fundy was decommissioned in 1996 and the fate of the vessel is unknown.
The Lindormen class is a class of two minelayers built for the Royal Danish Navy to replace the Lougen-class minelayers that dated from World War II. The Lindormen class was designed to lay controlled controlled minefields in the Baltic Sea during the Cold War as part of NATO's defence plan for the region. They were taken out of service by the Danish in 2004, put up for sale in 2005 and transferred to Estonia in 2006.
