World of Warships Supertest: Dutch Tier X Freemium Destroyer Tromp
4 min readHistorical background
The Tromp-class was a pair of flotilla leaders (Tromp and Jacob van Heemskerck), intended to lead a squadron of destroyers. Tromp was laid down in January 1936, launched in May 1937, and commissioned in August 1938.
At the start of World War II, the ship was primarily deployed in patrols and escort duties as part of the Netherlands East Indies Squadron. Due to the rising concerns about war with Japan, tensions increased in the region, and in November 1941, Tromp was charged to look for Vichy France merchant ships. Later that year, she was used to help research the missing HMAS Sydney (which turned out to have been sunk by the German raider Kormoran).
The opening of the war in the Pacific started badly for Tromp, being hit eleven times by the Japanese destroyers Asashio while only being able to score two hits on her and Oshio. Tromp was quickly patched up and brought back into service in May 1942. For the rest of the war, she mostly took part in convoy escort with some more exciting moments such as Operation Crimson in April and May 1944. Her final action in the war was her assistance in the recapture of Borneo from the Japanese by bombarding their positions before allied landings.
After the war, the ship was used to ship back home former prisoners-of-war before undergoing a massive refit from May 1946 until mid-1948. She would spend the rest of her career as a training or accommodation ship before being decommissioned in 1955 and later scrapped in 1969.
In World of Warships, Tromp appears as she was at the end of the Second World War. She is the first destroyer in the game able to use Dutch airstrikes.

For the classic reminder, this is a ship in testing, anything can change so don’t look at her like she would already be released.

The Armor
For some reason, Tromp has internal armor and not just one or two hidden plates. Here, we are talking about a fully shaped citadel. My personal theory is that the ship was initially intended as a low-tier cruiser but it is impossible to get any real evidence of that.

Personal Opinion
Tromp really is a weird ship when it comes to her design. The ship itself looks horrible. While she has a lot of HP, she is sluggish, has poor firepower, doesn’t have a Smoke Generator or Repair Party, and her concealment is nothing to write home about.
Where it gets interesting is when we talk about her airstrikes. While they have only 8 km of range and the bombs only have 20 mm of penetration, you shouldn’t stop there. They have a very short reload and also, the game files indicate that the bombs have a much shorter falling time than the other Dutch airstrikes. This could lead to them being much easier to land than others.
