The Santa María class of guided missile frigates is the Spanish Navy's designation for six warships based on the United States Oliver Hazard Perry-class frigates. Spanish ships have a slightly bigger beam and were built with a greater weight reserve for future improvements. Other changes from the basic model include Meroka replacing Phalanx and a RAN-12L air search radar to provide low horizon coverage against sea skimmers cueing the Meroka CIWS mount. The Nettunel EW suite replaced the SLQ-32 system fitted aboard US ships. The first ship Santa Maria entered service in 1986.
The Admiral Petre Bărbuneanu-class corvette is a series of four corvettes designed and constructed for the Romanian Naval Forces primarily for anti-submarine warfare. Only two corvettes out of a total of the four are still in service. Designed and constructed in the 1980s, they are a product of the Cold War with their armament and sensors based on Soviet designs. This class of corvettes was superseded by the Rear-Admiral Eustațiu Sebastian (Tetal-II) class.
Santa María (F81) is the lead ship of six Spanish-built Santa Maria-class frigates of the Spanish Navy, based on the American Oliver Hazard Perry class design. The vessel was constructed in 1982 and was launched on 11 November 1984. Santa María was commissioned on 12 October 1986. The frigate has served in NATO maritime operations. In 2022, the ship suffered a fire that delayed its departure on a mission.
Reina Sofía (F84) is the fourth of six Spanish-built Santa María-class frigates of the Spanish Navy. The Santa María class is based on the American Oliver Hazard Perry-class design, providing an anti-air warfare platform with anti-submarine and anti-surface warfare capabilities at a reduced cost. Reina Sofía was constructed by Bazan and was laid down on 12 October 1987 and launched on 19 July 1989. The ship was commissioned in 1990 and has seen service in the Mediterranean Sea and off Somalia.
Numancia (F83) is the third of the six Spanish-built Santa Maria-class frigates of the Spanish Navy, based on the American Oliver Hazard Perry class design. The frigate was constructed in Spain by Bazan and was laid down on 8 January 1986, launched on 29 January 1987 and entered service with the Spanish Navy on 17 November 1989. Based at Rota, Numancia has been deployed to the Indian Ocean fighting piracy in Somalia as part of Operation Atalanta and to the Mediterranean Sea intercepting illegal trafficking of migrants as part of Operation Sophia.
Victoria (F82) is the second of the six Spanish-built Santa Maria-class frigates of the Spanish Navy, based on the American Oliver Hazard Perry class design. Constructed in 1983, the vessel was launched on 23 July 1986 and commissioned on 11 November 1987. The frigate has been assigned to Operation Atalanta, fighting piracy of the Somalian coast.
Newport-class tank landing ships were an improved class of tank landing ship (LST) designed for and employed by the United States Navy from 1969 to 2002. The ships were intended to provide substantial advantages over their World War II-era predecessors. Larger and faster than any previous LST design, they carried a ramp over the bow that allowed them to surpass 20 knots, a goal of the United States amphibious forces. 27 were planned of which twenty were completed, the high number due to the demands of US force projection estimates. However, the arrival of the air-cushioned landing craft which allowed for over-the-horizon attacks made the class obsolete in the eyes of the United States Navy. Placed in reserve, twelve were eventually sold to foreign navies, while the remaining eight have since been decommissioned.
The Belgian Navy, officially the Naval Component of the Belgian Armed Forces, is the naval service of Belgium.
The Chamsuri class are patrol boats originally constructed for and operated by the Republic of Korea Navy. The first entered service in 1979, and they have since seen service with five other navies, of which the Philippine Navy is currently the largest import user. These boats were built by the Korea Tacoma, and Korea SB & Eng. Masan shipyards. In Korean service the Chamsuri-class boats are being retired and replaced by Gumdoksuri-class patrol vessels.
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 Kortenaer class was a class of anti-submarine frigates of the Royal Netherlands Navy. Like other frigate types of the 1970s and 1980s, they featured a COGOG propulsion system with separate cruise and sprint gas turbines. Ten were built by De Schelde in Vlissingen and two by Wilton-Fijenoord in Schiedam between 1978 and 1982. Only ten served with the Royal Netherlands Navy: two were sold to Greece's Navy while still under construction and replaced by two Jacob van Heemskerck-class frigates which were an air defence variant of the Kortenaer class. The Greek frigates were renamed the Elli class. After service with the Dutch ended, eight of the frigates were sold to Greece in 1992 and the remaining two to the United Arab Emirates. Three of the ships have since been retired from active military service with one converted into the superyacht Yas.
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.
Gordi is a Wielingen-class frigate of the Bulgarian Navy with number 43. She was originally commissioned as Westdiep in the Belgian Navy.
The João Coutinho-class corvettes were a series of warships built for the Portuguese Navy for service in Portugal's African and Indian colonies. Initially rated as frigates, they were downgraded first to corvettes and then patrol vessels with age. They were designed in Portugal by naval engineer Rogério de Oliveira, but the urgent need of their services in the Portuguese Colonial War meant that the construction of the ships was assigned to foreign shipyards. Six ships were built; the first three ships were built by Blohm & Voss and the remaining three by Empresa Nacional Bazán. The ships were launched in 1970 and 1971. The relative cheap cost of the design led to it being the basis of several other classes in other navies. From 1970 until the end of the conflict in 1975, the corvettes were used for patrol and fire-support missions in Angola, Mozambique, Guinea and Cape Verde. After the African colonies gained their independence, the corvettes were assigned to patrol duties in Portuguese territorial waters.
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 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.
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 six Piratini-class patrol boats are a series of patrol vessels that were built for the Brazilian Navy at the Rio de Janeiro Navy Arsenal. Based on the United States Coast Guard Cape-class cutter design, they were built between 1970 and 1971 as coastal patrol vessels. In 1993 they were moved from coastal patrol to riverine patrol.
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.
