When the Hr. Ms. Tromp, a Tromp-class cruiser, was built between 1936 and 1938, it was the most modern ship in its class.
The cruiser’s involvement in the search for HMAS Sydney, following its battle with the German raider Kormoran, stands out as a crucial moment. Subsequently, Tromp undergoes repairs and modifications in Australia, becoming part of the Allied forces in the Pacific theatre.
The ship participated in various operations, including the Balikpapan campaign, where it played a significant role in bombarding Japanese positions. The post-war period sees Tromp’s service in the Dutch East Indies, its classification as immobile, and its role as an accommodation ship.
The following list is abstracted from the information on this ship from the Netherlands Navy. It shows the main activities in relation to Australia. After the Fall of the Netherlands East Indies in March 1942 Hr.Ms. Tromp mainly operated from Australia.
