HSwMS Magne was a notable torpedo boat destroyer of the Royal Swedish Navy, constructed by the British shipbuilder Thornycroft and launched on August 2, 1905. The vessel measured approximately 65.78 meters (215 feet 10 inches) in length at the waterline, with a beam of 6.30 meters (20 feet 8 inches) and a draught of 2.49 meters (8 feet 2 inches). Displacing around 430 long tons (440 tonnes) at full load, Magne featured a distinctive turtleback forecastle that was longer than that of her predecessor, Mode, and was equipped with four funnels. Power was supplied by four coal-fed Thornycroft-Schutz water-tube boilers generating steam at 240 psi, which drove two triple-expansion steam engines rated at 7,200 indicated horsepower, enabling her to reach a contract speed of 30.5 knots (35.1 mph). During acceptance trials, she achieved a speed of 30.713 knots, though in Swedish service, her top speed was slightly lower, around 29 knots. Her armament comprised six 57 mm (2.2 inch) QF guns and two 450 mm torpedo tubes mounted aft. She had a crew complement of 67 officers and ratings. Magne’s construction was part of Sweden’s naval expansion in the early 20th century, and she served as the basis for subsequent Swedish destroyer designs, including the Wale and Ragnar classes. After being delivered to Sweden, she was fitted with armament and deployed along Sweden’s west coast during the political crisis preceding the dissolution of the Union between Sweden and Norway. Throughout World War I, Magne performed neutrality patrols and escort duties, notably forcing the Russian submarine Alligator out of Swedish waters in 1916 near Gotland. She was laid up at the end of 1918, stricken from the naval register in 1936, and ultimately used as a target before being sold for scrap in 1943. Magne’s service reflects her importance in Sweden’s early 20th-century naval defense and maritime sovereignty efforts.
