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 Le Redoutable-class submarine was a ballistic missile submarine class of the French Navy. In French, the type is called Sous-marin Nucléaire Lanceur d'Engins (SNLE), literally "Missile-launching nuclear submarine". When commissioned, they constituted the strategic part of the naval component of the French nuclear triad, then called Force de frappe.
USS Frederick (LST-1184) was a Newport-class tank landing ship which replaced the traditional bow door-design tank landing ships (LSTs) of the United States Navy. The ship was named after the city of Frederick, Maryland and Frederick County, Maryland. The vessel entered service in 1970 with the United States Pacific Fleet and saw service during the Vietnam War, and the Persian Gulf War earning three battle stars. The ship was decommissioned in 2002 and put up for sale.
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.
Argonaute is an Aréthuse-class submarine, and the fourth ship of the French Navy to bear the name. Launched on 29 June 1957, the submarine served as flagship within the Toulon submarine squadron. Argonaute was decommissioned on 31 July 1982. The vessel was converted to a museum ship in 1989 and located in Paris.
The Wielingen class is a class of four multi-functional frigates constructed for and operated by the Belgian Naval Component. In service from 1976 to 2008 with the Belgians, three of the class were sold to Bulgaria for service with the Bulgarian Navy beginning in 2004. The fourth, Westhinder, ran aground in 1988, was decommissioned in 1993 and was scrapped.
The Aréthuse class were submarines built for the French Navy in the 1950s. They were designed as attack submarines for anti-submarine warfare and were referred to as Sous-marins de Chasse by the French Navy. These submarines had advanced sensors and were very quiet. They were influenced by the World War II German Type XXIII U-boats. The Daphné class are an enlarged version built for the French, Pakistani, Portuguese, Spanish and South African navies.
The Uzushio-class submarine was a series of seven submarines in service with Japanese Maritime Self Defense Force during the Cold War between 1972 and the mid-1990s. They were the first generation of the teardrop type submarine that valued the underwater performance against that of the preceding conventional-hull type Asashio class. Many were converted to training submarines (ATSS) towards the end of their lives.
The Natsushio-class submarines were a pair of submarines constructed and operated by the Japan Maritime Self-Defense Force during the Cold War. They were a development of the Hayashio-class submarines and are sometimes considered the same class. They were small and limited in capability but were thought to be a successful class. They entered service in 1963–1964 and were deleted in 1978.
The Asashio-class submarine is a submarine class of Japanese Maritime Self-Defense Force comprising four boats. This class is the successor of Ōshio. The class were the first fleet submarines constructed for post-war Japan. The first submarine was authorized as part of the 1963 shipbuilding programme. Their design improved on previous Japanese classes by being larger to obtain better seaworthiness with greater torpedo stowage. The class entered service in the late 1960s and remained as such until the mid-1980s when they were taken out of service.
HMS Olympus was an Oberon-class submarine that served in the Royal Navy, and later in the Canadian Forces as a submarine trainer.
USS Boulder (LST-1190) was the twelfth of twenty Newport-class tank landing ships of the United States Navy (USN) which replaced the traditional bow door-design tank landing ships (LSTs). Named after the county in Colorado, the ship was constructed by National Steel and Shipbuilding Company of San Diego, California. The LST was launched in 1970 and was commissioned in 1971. Boulder was assigned to the United States Atlantic Fleet and deployed in the Caribbean and Mediterranean Seas. In 1980, the ship was transferred to the Naval Reserve Force. In 1988, Boulder ran aground off Norway during a military exercise. The vessel was decommissioned in 1994 and laid up at the Naval Inactive Ship Maintenance Facility in Philadelphia, Pennsylvania. The ship was struck from the Naval Vessel Register in 2008 and towed to Brownsville, Texas for scrapping in 2022.
USS Racine (LST-1191) was the thirteenth of twenty Newport-class tank landing ships of the United States Navy (USN) which replaced the traditional bow door-design tank landing ships (LSTs). The second ship named after the city in Wisconsin, the ship was constructed by National Steel and Shipbuilding Company of San Diego, California. The LST was launched in 1970 and was commissioned in 1971. Racine was assigned to the United States west coast and deployed to the western Pacific Ocean during the Vietnam War. The ship was transferred to the Naval Reserve Force in 1981. The LST was decommissioned in 1993 and placed in reserve. Racine was struck from the Naval Vessel Register in 2008 and after an attempted sale to Peru failed, was discarded as a target ship during a sinking exercise in July 2018.
USS Bristol County (LST-1198) was the last of the twenty Newport-class tank landing ships of the United States Navy (USN) which replaced the traditional bow door-design tank landing ships (LSTs). The LST was constructed by National Steel and Shipbuilding Company of San Diego, California. Bristol County was launched in 1971 and commissioned into the USN in 1972. Bristol County was assigned to the United States Pacific Fleet and remained in service until 1994 when it was decommissioned. Sold to Morocco that year, the vessel was recommissioned into the Royal Moroccan Navy as Sidi Mohammed Ben Abdellah. The ship remains in service.
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.
The Ruotsinsalmi-class minelayers were a two-strong class of minelayers in the Finnish Navy. The two ships, comprising Ruotsinsalmi and Riilahti, were constructed in Finland and saw service in the Winter War and World War II. Riihahti was sunk in an engagement with Soviet motor torpedo boats on 23 August 1943. Ruotsinsalmi survived the wars and remained in service in the post war Finnish Navy until being withdrawn in the 1970s.
BAP Abtao (SS-42) is an Abtao-class submarine of the Peruvian Navy. The vessel which was originally named BAP Tiburón ("Shark"), was constructed by the American Electric Boat company in the United States and launched in 1953. The Abtao class were the last submarines constructed by the United States for the export market. The submarine entered service in 1954 and by presidential decree, was renamed Abtao for the battle during the Chincha Islands War.
The Abtao class were four submarines of the Peruvian Navy that entered service between 1954 and 1957. They are also known as the Lobo class and the Dos de Mayo class and were constructed in the United States to a design based upon the United States Navy's Mackerel class. They were the last submarines to be constructed by the United States for the export market. All four submarines were powered by a diesel-electric system and armed with six 21-inch (533 mm) torpedo tubes. Two of the submarines also mounted a 5 in (127 mm)/25 caliber gun. The four submarines, initially named for animals, were all renamed in 1957 for famous Peruvian battles. Beginning in 1991, the submarines were taken out of service, with the last decommissioned in 1999. One, BAP Abtao, is a museum ship located in Lima, Peru.
SAS Spear, initially known as the SAS Maria van Riebeeck, was a Daphné-class submarine of the South African Navy (SAN). Built in France during the 1960s, the boat was the SAN's first submarine. It was scrapped in June–July 2003.
