Operational history

Both ships were laid down in 1929, with Klas Horn being constructed by Kockums and Klas Uggla built by the Karlskrona Navy Yard. Klas Horn was launched on 13 June 1931 and Klas Uggla on 18 June 1931. They were both completed in 1932. The Klas-class destroyers were sometimes used to escort Swedish ore carriers and German troop transports. On 17 September 1941, an unsolved explosion at Hårsfjärden Naval Base known as the Hårsfjärden disaster took place. Both Klas-class destroyers were sunk in the explosion along with the destroyer. In the explosion, thirty-three were killed and seventeen wounded from the three ships. Klas Horn was raised and returned to service, using parts from the non-repairable Klas Uggla. The vessel's anti-aircraft weaponry was increased to six 25 mm cannon. Klas Horn remained in active service until 1958. From 1958 until 1967, the ship was used as a training hulk. On 14 November 1967, Klas Horn was sold for scrap.
