Template:Short description Template:Use dmy dates
Template:Infobox ship imageTemplate:Infobox ship class overviewTemplate:Infobox ship characteristicsThe Tromp class were two frigates built for the Royal Netherlands Navy during the 1970s to replace the Template:Sclasss 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 Template:Sclasss. A total of four new frigates have been built, including two also named Template:HNLMS and Template:HNLMS.

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.<ref name="Beveren17092024">Template:Cite magazine</ref> Initially the British 4.5-inch naval gun and French 100 mm naval gun were also considered, alongside the Bofors guns.<ref name="Nooteboom126">Nooteboom (2001), p. 126.</ref> However, as a result of austerity measures it was decided that the Bofors guns were a better option financially.<ref name="MS18092023">Template:Cite web</ref> The Bofors guns were refurbished naval guns that had been removed from the HNLMS Gelderland.<ref name="GCB276">Gardiner, Chumbley and Budzbon (1995), p. 276.</ref> Before installation they were extensively modified and modernized with the help of Wilton-Fijenoord.<ref name="Nooteboom126" /> This resulted in the naval guns becoming considerable more accurate.<ref name="Beveren17092024" />
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.<ref>Template:Cite news</ref><ref name="Nooteboom117">Nooteboom (2001), p. 117.</ref> As a result all succeeding frigates of the Royal Netherlands Navy had deckhouses made of steel.<ref name="Nooteboom117" />
In July 1981 the Soviet aircraft carrier Kiev entered the North Sea and was escorted by both ships of the Tromp-class.<ref>Template:Cite news</ref><ref>Template:Cite news</ref>
Between 1981 and 1982 Fokker delivered 3 new large radomes for the Tromp-class frigates (one for each ship and one for reserve).<ref>Template:Cite news</ref>
