Tromp-class Light Cruiser

Ships in class: HNLMS Tromp

The Tromp class was a class of light cruisers of the Royal Netherlands Navy. The hull shape was also known as the Argonaut 600. Originally the ships could not be called "cruiser" for political reasons. They were designed as "flotilla leaders" and their intended role was to be the backbone of a squadron of modern destroyers that was planned at the same time (only one of those was completed before the war broke out).

At the outbreak of World War II, Tromp was sent to the Dutch East Indies. Jacob van Heemskerk was still being completed in the naval shipyard in Den Helder when the German attack started on 10 May 1940, but she succeeded in escaping to the United Kingdom, where she was completed with a completely different armament set, as an anti-aircraft cruiser.
