Tromp-class Frigate

The frigate HNLMS Tromp (F801) at sea in 1995.

The Tromp-class were two frigates built for the Royal Netherlands Navy during the 1970s to replace the De Zeven Provinciën-class cruisers as squadron flagships.

The Tromp-class frigates entered service in 1975 and 1976 and served until 2007 and 2008. 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 SAM.

The ships were replaced by the De Zeven Provinciën-class frigates. A total of four new frigates have been built, including two also named HNLMS Tromp (F803) and HNLMS De Ruyter (F804).
