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 This class of corvettes was superseded by the Rear-Admiral Eustațiu Sebastian (Tetal-II) class.
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.
The Type 143 Albatros class was a class of missile bearing fast attack craft. Each vessel is named after a bird of prey including the albatross, condor and cormorant. Constructed by German shipbuilders Lürssen and Kröger, the vessels were intended to replace the Type 141 Seeadler class. The German Navy retired the class in 2005 and sold the boats off to Tunisia and Ghana.
The Chamsuri class are patrol boats originally constructed for and operated by the Republic of Korea Navy. They 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 Korea, the Chamsuri-class boats are being retired and replaced by Gumdoksuri-class patrol vessels.
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 Leeuwin class is a two-ship class of hydrographic survey vessels operated by the Royal Australian Navy (RAN). Leeuwin and Melville were ordered from NQEA Australia in 1996, and were commissioned in 2000. The ships are capable of charting waters up to 6,000 metres (20,000 ft) deep, carry three Fantome-class survey boats, and could operate an AS 350B Squirrel helicopter. In addition to surveying duties, since 2001 both vessels have been used to supplement the RAN patrol force. Leeuwin and Melville are based at HMAS Cairns, and are active as of 2023.
The João Belo class, also known as Comandante João Belo class, is a class of four frigates of French design, based on the Commandant Rivière class but fitted for tropical service. Ordered by the Portuguese Navy in 1964, the four ships of this class were constructed at the shipyard in Nantes, France between 1965 and 1967. The first ship entered Portuguese service in 1967. The frigates were used for ocean patrol of Portuguese colonies and later, joined NATO's STANAVFORLANT unit. The first unit was discarded in 2003, followed by a second in 2004. The final two ships were taken out of service in 2008 sold to the Uruguayan Navy. The third ship was discarded in 2021, and the last ship was decommissioned on 12 August 2022.
The Inhaúma class are a series of five corvettes operated by the Brazilian Navy. These ships were built in Brazil and designed with assistance from the German company Marine Technik. It was originally planned to build 12 to 16 ships but the economic situation in Brazil did not permit this and only five vessels were built. The first two ships were constructed at the Arsenal de Marinha in Rio de Janeiro, the second pair by Verolme. The programme was considerably delayed due to funding issues and the Brazilian Verolme yard's insolvency in 1991 which forced Júlio de Noronha and Frontin to be completed by Arsenal da Marinha. The first ship entered service in 1989 and the last in 2008. Three of the five ships have been taken out of service and one was sunk in a missile exercise in the Atlantic Ocean in 2016.
China first received a single unit of Soviet Osa-class missile boat in January 1965, and four more in 1966 through 1967 and the last two in 1968. The Hudong Shipyard built the Chinese version as Type 021-class missile boat at a rate of ten boats per year with several different versions. The majority of this class is being transferred to reserve status. Several dozen remain active and these active units are being rearmed with C-101 supersonic anti-ship missiles. Bangladesh Navy Type 021 missile boats rearmed with C-704 high subsonic anti-ship missiles. These boats are effectively used in swarm missile attacks.
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.
The Baleares class were a group of five frigates built for the Spanish Navy in the late 1960s and 1970s. The ships were a modified version of the American Knox-class frigates. The key differences are the replacement of helicopter facilities by a medium-range surface-to-air missile system and associated radars. Constructed between 1968 and 1976, the Baleares class began entering service in 1973 and formed the 31 Escort Squadron, based at Ferrol. The five ships were upgraded several times during their service lives. The ships were retired beginning in the mid-2000s and replaced by the Álvaro de Bazán-class frigates on a one-to-one basis.
The Sparviero class, also known as the Nibbio class, are small hydrofoil missile boats capable of traveling at speeds of 46 knots. They were designed for and formerly used by the Italian Navy.
