The Tromp class were two frigates built for the Royal Netherlands Navy during the 1970s to replace the {{sclass|De Zeven Provinciën|cruiser}}s as squadron flagships.

The Tromp-class frigates entered service in 1975 and 1976 and served until 1999 and 2001. Both ships were built by Royal Schelde Shipyard in Flushing (Vlissingen). The ships served as fleet flagships and area air defence vessels. Their 3D radar under a large polyester radome gave the ships the nickname "Kojak" in the Netherlands Navy. Originally the ships were to have the British Sea Dart missile system, but this was changed to the more compact American Standard surface-to-air missile.

The ships were replaced by the {{sclass|De Zeven Provinciën|frigate|2}}s. A total of four new frigates have been built, including two also named {{HNLMS|Tromp|F803|2}} and {{HNLMS|De Ruyter|F804|2}}.

Design

=Armament=

The Tromp class frigates were armed with twin (1x2) Bofors 120 mm automatic naval guns with each gun being able to fire 38 to 42 shots per minute at a maximum distance of 21.6 kilometers.{{cite magazine |last=van Beveren |first=Arthur |date=17 September 2024 |title= Materieel van toen: Bofors kanon van 12 cm, nummer 10|url=https://magazines.defensie.nl/materieelgezien/2024/07/materieel-van-toen-bofors-kanon-van-12-cm-nummer-10 |magazine=Materieelgezien |publisher=Defensie.nl |language=Dutch}} Initially the British 4.5-inch naval gun and French 100 mm naval gun were also considered, alongside the Bofors guns.Nooteboom (2001), p. 126. However, as a result of austerity measures it was decided that the Bofors guns were a better option financially.{{cite web |author=|date=18 September 2023 |title=Trompklasse/ Geleide-wapenfregatten (Nederland)|url=https://marineschepen.nl/schepen/tromp.html |website=Marineschepen.nl |language=Dutch}} The Bofors guns were refurbished naval guns that had been removed from the HNLMS Gelderland.Gardiner, Chumbley and Budzbon (1995), p. 276. Before installation they were extensively modified and modernized with the help of Wilton-Fijenoord. This resulted in the naval guns becoming considerable more accurate.

Service history

In 1977 and 1979 the aluminium deckhouses on both ships were repaired at the shipyard of Koninklijke Maatschappij De Schelde after cracks had been found.{{cite news |url=https://resolver.kb.nl/resolve?urn=ABCDDD:010823890:mpeg21:a0282 |title=Marine-fregatten vertonen scheuren |author= |date=2 November 1978 |work=Trouw}}Nooteboom (2001), p. 117. As a result all succeeding frigates of the Royal Netherlands Navy had deckhouses made of steel.

In July 1981 the Soviet aircraft carrier Kiev entered the North Sea and was escorted by both ships of the Tromp-class.{{cite news |url=https://resolver.kb.nl/resolve?urn=ddd:010570348:mpeg21:p003 |title=Koerswijziging |author= |date=30 July 1981 |work=Limburgsch dagblad}}{{cite news |url=https://resolver.kb.nl/resolve?urn=ABCDDD:010847220:mpeg21:p001 |title=Marine houdt Russisch konvooi in de gaten |author= |date=30 July 1981 |work=Het Parool}}

Between 1981 and 1982 Fokker delivered 3 new large radomes for the Tromp-class frigates (one for each ship and one for reserve).{{cite news |url=https://resolver.kb.nl/resolve?urn=KBNRC01:000027350:mpeg21:a0155 |title=Fokker-Ypenburg levert marine radarkoepels |author= |date=10 March 1981 |work=NRC Handelsblad}}
