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.
HMS Amazon was the first Type 21 frigate of the Royal Navy. Her keel was laid down at the Vosper Thornycroft shipyard in Southampton, England. The ship suffered a fire in the Far East in 1977, drawing attention to the risk of building warships with aluminium superstructure.
The German destroyer D187 Rommel was one of three Lütjens-class guided-missile destroyers, a modified version of the American Charles F. Adams class, built for the Bundesmarine during the 1960s.
The Halifax-class frigate, also referred to as the City class, is a class of multi-role patrol frigates that have served the Royal Canadian Navy since 1992. The class is the outcome of the Canadian Patrol Frigate Project, which dates to the mid-1970s. HMCS Halifax was the first of an eventual twelve Canadian-designed and Canadian-built vessels which combine traditional anti-submarine capabilities with systems to deal with surface and air threats as well. All ships of the class are named after a major city in each province plus the cities of Ottawa and Montreal.
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.
The Almirante Padilla-class frigates is a series of frigates operated by the Colombian Navy. The designation of this class is Type FS 1500 and there are four ships in service. The ships were built by Howaldtswerke-Deutsche Werft (HDW) at Kiel, West Germany in the 1980s, with the first vessel commissioning in 1983 and the last in 1984. The frigates have undergone significant modification over their careers with the 2012 Orion Program Upgrade significantly modernising the vessels. Two similar ships operate as the Kasturi-class corvettes in the Royal Malaysian Navy.
HNLMS Jan van Brakel (F825) was a frigate of the Kortenaer class in service with the Royal Netherlands Navy from 1983 to 2001. She was renamed HS Kanaris (F464) on transfer to the Hellenic Navy in 2002.
Combined gas or gas (COGOG) is a propulsion system for ships using gas turbine engines. A high efficiency, low output turbine is used for cruising speeds with a high output turbine being used for high-speed operations. A clutch allows either turbine to be selected, but there is no gearbox to allow operation of both turbines at once. This has the advantage of not requiring heavy, expensive and potentially unreliable gearboxes. The reason that a smaller turbine is used for cruising is that a small turbine running at 100% power is more fuel efficient than a bigger turbine running at 50% power.
The Almirante Brown class is a class of warships built for the Argentine Navy. They were commissioned between 1983 and 1984, after the Falklands War. The class comprises four ships; Almirante Brown, La Argentina, Heroína and Sarandí. They are classified as either frigates or destroyers by different publications. The MEKO 360 type warships are based on modular designs which allow quick changes to the vessel's armaments depending on mission requirements. The modular nature of the construction also allows the ships to be modernized or refitted with greater ease. Six vessels were initially ordered, however two ships were cancelled and replaced with orders for MEKO 140 type hulls.
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 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.
NNS Aradu (F89) is a Nigerian frigate. She is the first of the MEKO 360 general purpose frigates built by the German Blohm + Voss company of Hamburg. The 125.6-metre ship is the largest in the Nigerian Navy. As a general purpose frigate, Aradu has capabilities for anti-air, anti-surface and anti-submarine warfare effectively, and participated in the 200th anniversary celebrations of the Battle of Trafalgar. The ship also possesses capability for naval fire support and electronic warfare. Additionally, she carries a ship-borne helicopter for anti-submarine warfare, search and rescue, and enhanced surveillance/detection.
The Marcílio Dias-class destroyers were three destroyers of the Brazilian Navy that served during World War II. They were based on the United States Navy's Mahan class. They entered service in 1943 and served on Atlantic convoy duty with the Allies. In July 1944, the three destroyers escorted the Brazilian Expeditionary Force to Italy. Following the end of the war, the destroyers remained in service, undergoing modernisation. Two were discarded in 1966, with the last taken out of service in 1973.
Dat Assawari was a frigate operated by the Libyan Navy. The ship was built by VT Group in the United Kingdom. It was ordered in February 1968 and delivered in 1973. The ship's design, the Vosper Mk 7 is a modified version of the Alvand-class frigate built for the Iranian Navy. The ship had an extensive refit in Italy by CNR Riva Trigoso 1979–1980 when new sensors and missiles were installed. During the refit, the ship was mined by French commandos from SDECE. The vessel returned to service in 1983, but returned to Italy for repairs in 1984–1985 and 1989–1990. The frigate was reportedly scrapped in the late 1990s.
HNLMS Van Kinsbergen (F809) was a frigate of the Kortenaer class. The ship was in service with the Royal Netherlands Navy from 1980 to 1995. The frigate was named after Dutch naval hero Jan Hendrik van Kinsbergen.
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 Rolls-Royce Marine Olympus is a marine gas turbine based on the Rolls-Royce Olympus aircraft turbojet engine.
HNoMS Oslo was an Oslo-class frigate of the Royal Norwegian Navy. The frigate was launched on 17 January 1964, and commissioned on 29 January 1968. Oslo ran aground near Marstein Island on 24 January 1994. One officer was killed in the incident. The next day, on 25 January, she was taken under tow. However as the situation deteriorated, the tow was let go and the frigate sank.
HNLMS Kortenaer (F807) was a frigate of the Kortenaer class. The ship was in service with the Royal Netherlands Navy from 1978 to 1997 and today serves as HS Kountouriotis with the Hellenic Navy. The frigate was initially named after Dutch naval hero Egbert Bartholomeusz Kortenaer and then after Pavlos Kountouriotis, distinguished Admiral of the Hellenic Navy, responsible for Greek naval victories in the Aegean Sea that secured the Aegean for Greece during the First Balkan War. The ship's radio call sign was "PADA".
HNLMS Callenburgh (F808) was a frigate of the Kortenaer class. The ship was in service with the Royal Netherlands Navy from 1979 to 1994. The frigate was named after Dutch naval hero Gerard Callenburgh. The ship's radio call sign was "PADB".
