A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.
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 46 Knox-class frigates were the largest, last, and most numerous of the US Navy's second-generation anti-submarine warfare (ASW) escorts. Originally laid down as ocean escorts, they were all redesignated as frigates on 30 June 1975, in the 1975 ship reclassification plan and their hull designation changed from 'DE' to 'FF'. The Knox class was the Navy's last destroyer-type design with a steam turbine powerplant.
The Karel Doorman-class frigates are a series of eight multi-purpose vessels built for the Royal Netherlands Navy. Its namesake is Karel Doorman, a Dutch naval officer whose ship was struck by a Japanese torpedo in the battle of the Java Sea in 1942, and who, as a result of which, went down with his ship.
The Cassard class was a class of two anti-air warfare destroyers of the French Navy introduced in the latter 1980s/early 1990s. The class was an air defence variant of the Georges Leygues class. The two classes have a different armament and propulsion system mounted on an identical hull. Their primary role was to provide air cover for a fleet, an aeronaval group, a convoy & a littoral point. Their secondary role was to manage air assets coordination & aircraft control for the force, especially through Link 16.They can also be used for research, identification or presence missions. Both ships were assigned to the Force d'Action Navale. The lead ship of the class, Cassard, was retired in 2019 followed by the retirement of Jean Bart in 2021.
HNLMS Jan van Brakel (F825) was a frigate of the Kortenaer class. The ship was in service with the Royal Netherlands Navy from 1983 to 2001. She was named after Jan van Brakel, a Dutch naval commander from the seventeenth century. She was renamed HS Kanaris (F464) on transfer to the Hellenic Navy in 2002.
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 while still under construction and replaced by two Jacob van Heemskerck-class frigates which were an anti-air warfare 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.
HMS Rothesay was the lead ship of the Rothesay or Type 12M class of anti-submarine frigates of the British Royal Navy. She was commissioned in 1960 and scrapped in 1988.
HMS Brighton was a Rothesay or Type 12I class anti-submarine frigate of the Royal Navy.
HMS Lowestoft was a Rothesay-class or Type 12 class anti-submarine frigate of the British Royal Navy. Lowestoft was reconstructed in the late 1960s to largely the same pattern as the third group of Leander-class frigates, with new radar and fire control and a hangar and pad for a Westland Wasp helicopter for longer range, anti-submarine, engagement. In the late 1970s it was converted as the prototype towed array frigate for the Royal Navy, but retained its full armament. Lowestoft was sunk as a target on 8 June 1986 by HMS Conqueror using a Tigerfish torpedo. She was the last Royal Naval target to be sunk still displaying her pennant number.
HMS Whitby was a Whitby-class or Type 12 anti-submarine frigate of the Royal Navy of the United Kingdom built by Cammell Laird and Co Ltd, Birkenhead. She was launched on 2 July 1954 and commissioned on 10 July 1956.
The Holland-class destroyers were built for the Royal Netherlands Navy in the 1950s. They were the first major warships designed and built by the Dutch after World War II. In contrast to previous Dutch Navy practice the ships were named after provinces rather than admirals.

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.
