The 2-pounder gun, officially the QF 2-pounder and universally known as the pom-pom, was a 40 mm (1.6 in) British autocannon, used as an anti-aircraft gun by the Royal Navy. The name came from the sound that the original models make when firing. This QF 2-pounder was not the same gun as the Ordnance QF 2-pounder, used by the British Army as an anti-tank gun and a tank gun, although they both fired 2 lb (0.91 kg), 40 mm (1.6 in) projectiles.
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 In the period immediately before the Second World War, the ship's armament was deemed out of date, and in 1939 and 1940 significant improvement to the vessel's anti-aircraft capability were made with the addition of 25 mm (1 in), 40 mm (1.6 in) and 57 mm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.
The Sverige-class coastal defence ships were a class of coastal defence ships that, at the time of introduction, were the largest ships to serve in the Swedish Navy. Their design was completely new and was influenced by the ships of the time. Their armament consisted of four 283 mm (11 in)/45 cal. Bofors guns in two turrets and eight 152 mm (6 in) Bofors guns in one double and six single turrets. During the Second World War they were the backbone of the Swedish Navy.
HSwMS Drottning Victoria was a Sverige-class coastal defence ship (Pansarskepp) for the Royal Swedish Navy in the 1910s.
HSwMS Sverige was a Sverige-class coastal defence ship (Pansarskepp) commissioned by Sweden during the last year of the First World War. The ship cost approximately 12 million kronor, a sum raised entirely by public donations. The fundraising was done because of the Karl Staaff government's reluctance to spend money on a new battleship. In addition to its impressive cost, the ship also had a significant impact on the Swedish Navy and its capabilities.
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.
The 15 cm SK L/45 was a German naval gun used in World War I and World War II.
The Bofors 152 mm kanon m/42 is a naval gun for use on ships. It was initially used aboard light cruisers and cruisers including the Swedish Tre Kronor class and the Dutch De Zeven Provinciën class, after World War II. The last active ship to use the gun was the Peruvian Navy cruiser BAP Almirante Grau and was the largest naval gun still in active service prior to the commissioning of USS Zumwalt in October 2016, which is armed with the 155 mm Advanced Gun System.
The Bofors 283 mm M/12 naval gun was a naval rifle of 283 millimetres (11.1 in) and 45 calibers used as the main battery of the Swedish Sverige-class coastal defence ships. It was designed and built by Bofors a few years before the First World War.
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 Canon de 37 mm Modèle 1925 was a widely used family of French anti-aircraft guns used by the French Navy during World War II.
HSwMS Oscar II was a coastal defence ship or Pansarskepp of the Swedish Navy. The vessel had a long career lasting over sixty years. A development of the preceding Äran-class coastal defence ship, the ship mounted a powerful armament on a small hull, which necessitated sacrificing speed and endurance. This design decision allowed Oscar II to match the firepower of contemporary armoured cruisers while still carrying the armour of a battleship. Protected by an armoured belt that had a maximum thickness of 150 mm (5.9 in), the ship was armed with a main battery of two 210 mm (8.3 in) Bofors guns mounted separately fore and aft. Maximum speed was 18 knots.
HSwMS Karlskrona was a destroyer of the Royal Swedish Navy that served during the Second World War and in the Cold War. The fourth member of the Göteborg or city class, which was designed as an improvement on the previous Ehrensköld class, Karlskrona was launched on 16 June 1939. The destroyer served in the Coastal Fleet during the war, protecting Swedish neutrality and escorting convoys. After the war, the ship was upgraded between 1950 and 1951 with enhanced fire control and an armament improved with the introduction of the Bofors 40 mm anti-aircraft gun. Ten years later, in 1961, Karlskrona was designated a fast anti-submarine frigate and the torpedo tubes were replaced by Squid mortars. The vessel was decommissioned on 1 July 1974 and broken up in 1979.
HSwMS Malmö was a destroyer of the Royal Swedish Navy that served during the Second World War and in the Cold War. The third member of the Göteborg or City class, an improvement on the previous Ehrensköld class, Malmö was launched on 22 September 1938. The destroyer served during the war on neutrality patrols and escorts, as well as the evacuation of Gotland in 1941. After the war, the ship was upgraded multiple times. Armament was improved with the introduction of the Bofors 40 mm anti-aircraft gun in 1951 and the Squid mortar ten years later. The latter followed the redefinition of Malmö as an anti-submarine frigate. The ship served in that role for a short time, being decommissioned on 1 February 1965 and broken up as the part of a wider Swedish naval programme of retiring destroyers and frigates.
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.
HSwMS Oden was the lead ship of the Oden class of first-class coastal defence ships (Pansarskeppen) constructed for the Swedish Navy. The ship was armed with two 25 cm (9.8 in) guns provided by the French manufacturer Société Nouvelle des Forges et Chantiers de la Méditerranée. The vessel was launched in 1896 and was first upgraded with additional 12 cm (4.7 in) guns after running aground in 1901. In 1913, the warship accidentally sank the gunboat Urd and was taken out of service the following year to be updated with new boilers and an upgraded armament. Most noticeably, during this rebuild, one funnel was fitted to replace the two that had been a feature of the ship from the start. Oden was retired from front-line service in 1937 and broken up in 1943.
HSwMS Niord was a Swedish first-class coastal defence ship (Pansarskepp) of the Oden class. A follow-on to the name-ship of the class Oden, Niord differed in having improved Harvey steel armour and two additional casemate-mounted 12 cm (4.7 in) guns. The vessel was launched in 1899 in Gothenburg. After an update completed in 1917 that radically altered the ship's appearance by replacing the two funnels with one, Niord was retired from front-line service in 1922. After serving as a barracks ship and tender supporting, in 1925, the seaplanes of what would become the Roslagen Air Corps, unemployed sailors in Stockholm in 1931 and the Cabin Boy Corps (Skeppsgossekåren) of Marstrand in 1935, the vessel was rearmed as an anti-aircraft battery during the Second World War. Decommissioned in 1944, Niord was broken up in Karlskrona in 1945.
