Tre Kronor-class cruiser
The ''Tre Kronor'' class (English: ''Three Crowns'' class) was a class of two cruisers built for the Swedish Navy during World War II.
==Design and development==
The outbreak of World War II caused the Swedish Navy to change its naval strategy, with it being decided to base the fleet on two squadrons of destroyers, each of which would be led by a cruiser, instead of the existing organisation of slow coastal defence ships and small torpedo boats. In 1940, therefore, the Swedish government decided that two cruisers were to be built. The cruisers were designed by the Italian shipyard CRDA in 1940–1941.〔Whitley 1999, pp. 225–226.〕
The main armament was seven Bofors 152 mm guns, with one triple turret forward and two twin turrets aft. The guns were being built by Bofors for the s being built in the Netherlands for the Royal Netherlands Navy but were taken over by the Swedish government when the Netherlands surrendered to Germany in May 1940.〔Whitley 1999, pp. 197, 226.〕 They could fire a shell to a range of at a rate of 12–15 rounds per minute,〔Friedman 1997, p. 449.〕 and could elevate to 70 degrees, being capable of both anti-surface and anti-aircraft use.〔 Additional anti-aircraft armament was provided by 20 Bofors 40 mm guns in 10 twin turrets and seven 25 mm guns. Six torpedo tubes were fitted, and the ship could also carry 160 mines.〔Whitley 1999, p. 226.〕〔
A political debate broke out about the cruisers, with this, together with rework of the design, ensured that work did not start until 1943. The ships were built by the Götaverken and Eriksberg shipyards in Gothenburg. was launched on 16 December 1944, and on 17 November 1945.
