The Arethusa-class cruisers were a class of eight oil-fired light cruisers of the Royal Navy all ordered in September 1912, primarily for service in the North Sea. They had three funnels with the middle one somewhat larger in diameter than the others. All served in the First World War. They were found to be very cramped internally.
HSwMS Äran was a Swedish first class coastal defence ship (Pansarskepp). A development of Dristigheten, the Äran class mounted the same 21 cm (8.3 in) main guns, but differed in the layout of the secondary armament. The vessel was launched in 1901 by Gustaf V breaking a bottle of champagne on her bow, the last time that ceremony took place following complaints that breaking wine on a ship was sacrilegious. The warship served on neutrality patrols in the First World War and was damaged after running aground in 1932. In the period immediately before the Second World War, the ship's armament was deemed out of date, and in 1939 and 1940 significant improvement to the vessel's anti-aircraft capability were made with the addition of 25 mm (1 in), 40 mm (1.6 in) and 57 mm (2.2 in) guns. After the war, the Swedish Navy decided to retire all its coastal defence ships. Äran was retired in 1947 and sold to be broken up in 1951, the last sections of the ship finally sinking in 1968.
HSwMS Clas Fleming was a cruiser-minelayer built before World War I for the Royal Swedish Navy. Completed in 1914, the ship performed limited neutrality patrols in the Sea of Åland and the northern reaches of the Stockholm Archipelago during the war. She was placed in reserve in 1917 to be modified to make laying mines safer and remained in that status until the beginning of World War II in 1939 to save money. Clas Fleming was activated for a short time that year to lay defensive minefields before she began a reconstruction that installed an early version of gas turbines, the first warship in the world to be so equipped. After her sea trials were completed in 1940, she was on active service for the rest of the war. Clas Fleming was again reduced to reserve at that time and did not leave the dockyard before she was stricken from the navy list in 1959. The ship briefly served as a target ship before being sold for scrap the following year.
HSwMS Wachtmeisterwas the second and last of the Wrangel-class destroyers built for the Royal Swedish Navy during World War I. Completed in 1918, the ship was rammed by another Swedish destroyer four years later. At the beginning of World War II in 1939 she was assigned to the Gothenburg Squadron. Wachtmeister was decommissioned in 1947 and was subsequently sold for scrap in 1950.
HSwMS Tre Kronor was a cruiser built for the Royal Swedish Navy during the Second World War.
The Tre Kronor class was a class of two cruisers built for the Swedish Navy during World War II, comprising Tre Kronor and Göta Lejon. Tre Kronor was discarded in 1968 and Göta Lejon was sold to Chile in 1971. Renamed Almirante Latorre, she remained in service until being discarded in 1986.
HMS Eden was a Hawthorn Leslie type River-class destroyer ordered by the Royal Navy under the 1901 – 1902 Naval Estimates. Named after the River Eden in northern England, she was the second ship to carry this name since it was introduced in 1814.
The 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.
The Klas class, also referred to as the Klas Horn class, was a pair of destroyers in service with the Swedish Navy from 1932 to 1958. They are sometimes considered part of the preceding Ehrensköld-class destroyers. Two ships in the class was constructed between 1930 and 1932, HSwMS Klas Uggla and HSwMS Klas Horn. The ships were involved in the Hårsfjärden disaster in 1941, in which both ships were damaged. Klas Uggla was raised but decommissioned, Klas Horn was repaired and continued to serve in the navy until 1958.
The Ehrensköld class was the first "modern" class of destroyer built by the Swedish Navy after the First World War. It introduced several new features, mainly heavy armament in three 12 cm guns and the new 53 cm torpedo. The class included two vessels, Ehrensköld and Nordenskjöld, which were both launched in 1926 and entered service in 1927. They patrolled the Baltic Sea until 1963, after which they became target vessels. Nordenskjöld was scrapped in 1964 and Ehrensköld in 1974.
The Giuseppe Sirtori class consisted of four destroyers built for the Italian Regia Marina during World War I. All four ships saw action during the war, survived the post-war reduction in Italian naval strength, and were lost during World War II.
The Nembo class was a class of destroyer of the Italian Regia Marina. Six destroyers were built by the Pattison shipyard of Naples between 1899 and 1905, to a design based on the contemporary destroyers of the British shipyard Thornycroft. They were active in the Italo-Turkish War and in the First World War, where three were lost.
The Wrangel class was a class of four destroyers built for the Royal Swedish Navy during World War I of which two were cancelled before they were laid down. Completed in 1918, they were in service until shortly after the end of World War II in 1945. Wrangel served as a target ship before she was sunk in 1960 and Wachtmeister was broken up for scrap in 1951.
HSwMS Wrangel was the lead ship of her class of two destroyers built for the Royal Swedish Navy during World War I. At the beginning of World War II in 1939 she was assigned to the Gothenburg Squadron. The ship was stricken in 1947 and was subsequently used as a pilot and target ship. Wrangel sunk as a target in 1960.
The Ragnar class was a class of three destroyers built for the Royal Swedish Navy before World War I. The class consisted of HSwMS Ragnar, HSwMS Sigurd, and HSwMS Vidar. The lead ship, Ragnar, was launched May 30, 1908. The design was based on the earlier destroyer Wale. The Ragnar class led a relatively quiet service life performing routine missions such as escorts and exercises between their commissioning before World War I and their decommissioning shortly after World War II.
HSwMS 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.
Several ships of the Swedish Navy have been named HSwMS Tordön or HSwMS Thordön, named after the Old Norse word for thunder:
HSwMS Tapperheten was a Äran-class coastal defence ship that served with the Swedish Navy. A development of Dristigheten, the Äran class mounted the same 21 cm (8.3 in) main guns, but differed in the layout of the secondary armament. The vessel was launched in 1901 and served with the coastal defence squadron at Karlskrona. In 1907, the warship attended a naval review by Edward VII. Tapperheten ran aground off the island of Sandön in 1914, earning the nickname, Fastigheten (Permanence) due to the lack of damage received until the vessel was refloated six months later. Subsequently, the vessel served in the First World War protecting Sweden's neutrality. The warship gained a second nickname, Tappaankarheten, for losing an anchor in 1927. After an upgrade to the anti-aircraft armament, the ship also served in the Second World War before retiring in 1947 and being sold to be broken up in 1952.
HSwMS Manligheten was a Äran-class coastal defence ship that served with the Swedish Navy. A development of Dristigheten, the Äran class mounted the same 21 cm (8 in) main guns, but differed in the layout of the secondary armament. The vessel was launched in 1903 and served on neutrality patrols in the First World War. During the two decades following the conflict, the ship undertook a number of international tours that called at ports in Britain, the Netherlands and Spain. Manligheten ran aground in 1930 and was freed by an ingenious manoeuvre by the destroyer Wachtmeister, which created waves by speeding past the stranded vessel. While serving in the Second World War, the vessel was damaged by a paravane in 1939 and modernised between 1940 and 1941. Decommissioned in 1950, Manligheten was broken up, although the ship's hull remaining in use as a pontoon until 1984.
HSwMS Wasa was a Äran-class coastal defence ship that served with the Swedish Navy. The vessel served in the front line for substantially less time than the rest of the class. A development of Dristigheten, the Äran class mounted the same 21 cm (8.3 in) main guns, but differed in the layout of the secondary armament. Wasa was launched in 1901 and served as part of the coastal defence fleet, including taking part in neutrality patrols during the First World War. The ship was retired from front-line service in 1924 and withdrawn from active service in 1940, thereafter acting as a decoy and, from 1951, a damage control training ship. Wasa was sold to be broken up in 1960.
