WThe Göteborg class was a Swedish World War II destroyer class. Built from 1936–1941 the class was designed as escort and neutral guard destroyers. In total six ships were constructed, HSwMS Göteborg, HSwMS Stockholm, HSwMS Malmö, HSwMS Karlskrona, HSwMS Gävle and HSwMS Norrköping. After World War II the destroyers, later rebuilt as frigates, continued to serve in the Swedish navy. The last ship was decommissioned in 1968.
WThe Halland-class destroyers were two ships built for the Swedish Navy in the 1950s. Four ships were planned, but the second pair were canceled. Two modified ships were exported to the Colombian Navy. These vessels were general purpose surface combatants.
WThe Mode class or Mjölner class was a class of four coastal destroyers commissioned by the Royal Swedish Navy during World War II. The design was based on the preceding Psilander class purchased from Italy but with Swedish equipment and armament. The destroyers served as coastal escorts. The class was moderately upgraded and reclassified as frigates during the early part of the Cold War. After nearly thirty years of service, the last vessel was retired in 1970.
WThe Öland class was a Swedish destroyer class. From 1943 to 1947 two destroyers were constructed, HSwMS Öland and HSwMS Uppland. Originally four ships were planned for the class but after the end of World War II two were canceled. When commissioned the ships were the largest destroyers that had ever served in the Swedish navy. The ships served in the navy until 1979 when the last ship was decommissioned.
WThe Romulus class was a class of two destroyers operated by the Royal Swedish Navy during the Second World War. The class consisted of HSwMS Romulus and HSwMS Remus. They were built in Italy as the Spica-class torpedo boats Spica and Astore in the mid-1930s and sold to Sweden in 1940. The two ships were adapted for northern conditions and remained in service during World War II and into the first decades of the Cold War. They were modernized and re-designated as anti-submarine frigates in 1953. Both ships were discarded in 1958.
WHSwMS Wale (3) was a destroyer of the Swedish Navy. Wale was built by Kockums Shipyard and launched on September 21, 1907 and delivered to the fleet on 11 April 1908. The vessel was based on the two former British-built destroyers HSwMS Mode and HSwMS Magne. Wale was the first destroyer to be built in Sweden and was influential in the development of the destroyers in that nation. After Wale, in the years 1907–1911, another five destroyers followed with essentially the same design. These were two ships of the Hugin class and three ships of the Ragnar class. Wale was decommissioned on 18 November 1940. She was sunk as a target outside Fårösund by the Swedish Coastal Artillery and the HSwMS Sundsvall on 26 September 1946.
WThe Wrangel class was a class of two destroyers built for the Royal Swedish Navy during World War I. The class consisted of HSwMS Wrangel and HSwMS Wachtmeister.
