HSwMS Romulus (27) was the lead vessel of her class of destroyers, originally built as the Italian Spica-class torpedo boat, and later acquired by the Royal Swedish Navy in 1940. Constructed during the 1930s, she was launched on 11 March 1934 and commissioned on 30 May 1935. The ship displaced approximately 630 long tons (640 tonnes) at standard load and up to 900 long tons (910 tonnes) at deep load. She measured 81.4 meters (267 feet 1 inch) in overall length, with a beam of 8.2 meters (26 feet 11 inches) and a draft of 2.3 meters (7 feet 7 inches). Propelled by two Tosi geared steam turbines, each driving a propeller shaft with steam supplied by paired Yarrow boilers, Romulus was designed to produce around 19,000 shaft horsepower, enabling a maximum speed of 34 knots (63 km/h; 39 mph). Her fuel capacity granted her a range of about 1,700 nautical miles (3,100 km; 2,000 miles) at 16 knots. The crew complement consisted of 99 personnel. The ship's main armament comprised three 100-millimeter (3.9-inch) dual-purpose guns—one on the forecastle and two superfiring at the stern. Modifications by the Swedish Navy enhanced her anti-aircraft defenses, adding three 20-millimeter Breda AA guns and two 13.2-millimeter M/31 heavy machine guns. She was also equipped with four 533-millimeter (21-inch) torpedo tubes in two twin mounts, located between the rear funnel and the stern gun. Additional armament included two depth charge throwers and the capacity to carry 28 mines. Originally launched as Spica, the vessel was impounded by the British during her delivery voyage in June 1940, but was released shortly thereafter and renamed Romulus. She was modified to operate under Arctic conditions and was fitted with Swedish equipment. Romulus served during World War II and into the Cold War, playing a role in Sweden's naval defense until she was stricken from the navy list on 15 August 1958.
