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.

Their 3D radar under a large polyester radome gave the ships the nickname "Kojak" in the Netherlands Navy.

[5] 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.

[8][9] As a result all succeeding frigates of the Royal Netherlands Navy had deckhouses made of steel.
