HMS Tre Kronor was a cruiser of the Swedish Navy built during the Second World War. At the start of the war most of the ships of the Royal Swedish Navy were quite old and the navy was in need of new ships. In 1940 the government decided that two cruisers were to be built. A political debate broke out about the cruisers and work did not start until 1943. The ship was to be built in Götaverken in Gothenburg.
