HSwMS Wachtmeister (10), later (26), was a destroyer of the Swedish Navy during World War I, built at Lindholm Shipyard in Gothenburg, and was launched on December 19, 1917, as the second of two destroyers of the Wrangel class. The ship class was among the most modern destroyers in the world just after the end of World War I. At the outbreak of World War II in 1939 she was stationed as part of the Gothenburg Squadron. Wachtmeister was decommissioned in 1947 and was subsequently sold for scrap in 1950. The ship was named after the Swedish noble family Wachtmeister. Design Wachtmeisters hull was made of nitrated steel. Like former Swedish destroyers, the ship had no proper superstructure on the bow, but had only a protective skirt wall for the command bridge, though there was a small superstructure on the stern. The propulsion machinery consisted of four steam boilers which delivered steam to two steam turbines. The machine generated an output of 11,500 horsepower, giving a maximum speed of 34 knots. Each boiler had a separate funnel, which led to the common four stack arrangement of the time. The two steam turbines were of a new type with reduction gears, which meant that the turbine speed could be shifted down to lower the propeller speed, giving the machinery a better efficiency. On delivery, the ship's main artillery consisted of two 7.5 cm guns m/12 that were placed on the front and rear deck. The close-range protection consisted of two 6.5 mm machine guns m/14 that were placed on either side of the command bridge. The torpedo armament consisted of six 45.7 cm torpedo tubes m/14. Four of these stood as in the previous class in two double stands on the main deck. What was new was that two more were placed behind gaps in the front of the hull. History Wachtmeister was built at Lindholm's Gothenburg shipyard and was launched on December 19, 1917. After fitting out and trials she was delivered to the Swedish Navy on October 19, 1918. During an exercise on the evening of June 8, 1922, Wachtmeister was rammed just ahead of the bridge by the destroyer . Three people who were in Vidars forebody were seriously injured, one later died during transport to the hospital. Wachtmeister got a 20-meter long imprint of the hull and three people were thrown into the water, there could soon
