Dunderberg, which is a Swedish word meaning "thunder(ing) mountain", was an ocean-going casemate ironclad of 14 guns built for the Union Navy. She resembled an enlarged, two-masted version of the Confederate casemate ironclad CSS Virginia. She was originally designed to have both gun turrets and a casemate but the turrets were deleted while the ship was still being built. Construction began in 1862, but progress was slow and she was not launched until after the end of the American Civil War in 1865.
A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. Vessels often have more than one level both within the hull and in the superstructure above the primary deck, similar to the floors of a multi-storey building, that are also referred to as decks, as are certain compartments and decks built over specific areas of the superstructure. Decks for some purposes have specific names.
The Sovetsky Soyuz-class battleships, also known as "Stalin's Republics", were a class of battleships begun by the Soviet Union in the late 1930s but never brought into service. They were designed in response to the Bismarck-class battleships being built by Germany. Only four hulls of the fifteen originally planned had been laid down by 1940, when the decision was made to cut the program to only three ships to divert resources to an expanded army rearmament program.
Duilio was the lead ship of the Duilio class of ironclad turret ships built for the Italian Regia Marina. Named for the Roman admiral Gaius Duilius, the ship was laid down in January 1873, was launched in May 1876, and was completed in January 1880. She was armed with a main battery of four 450 mm (17.7 in) guns, then the largest gun afloat, and she was capable of a top speed of around 15 knots.
The first South Dakota class was a group of six battleships that were laid down in 1920 for the U.S. Navy, but were never completed; designed to achieve 23 knots, they represented an attempt to catch up with the increasing fleet speeds of its main rivals, the British Royal Navy and Imperial Japanese Navy.
Pluton was a fast minelaying cruiser built for the French Navy in the late 1920s. She was also able to carry 1,000 troops on her mine deck as a fast troop transport. Shortly after completion she was modified and became a gunnery training ship, replacing the elderly armored cruiser Gueydon. Shortly before the beginning of World War II, she reverted to her original role and most of the gunnery training equipment was removed. She was sent to Casablanca, in French Morocco, when the war began to lay a minefield, but the order was cancelled a day later and she was ordered to disembark her naval mines. She exploded while landing her still-fuzed mines on 13 September 1939.
Montcalm was a Gueydon-class armoured cruiser built for the French Navy in the 1890s. The ship saw service during World War I in the Pacific. Following the war, Montcalm was used as an accommodation ship. In 1934, the vessel was renamed Trémintin and was sunk during World War II by British aircraft.
The Bouvines class consisted of a pair of ironclad coastal-defense ships built for the French Navy in the 1890s, Bouvines and Amiral Tréhouart. Thoroughly obsolete by World War I, the ships only played a minor role during the war. They were sold for scrap in 1920.
The French cruiser Gueydon was the name ship of her class of armoured cruisers built for the French Navy in the 1890s.
The Dévastation-class ironclads were a class of ironclad battleships that were laid down as part of the 1872 programme. They were a development of the 1876 ironclad Redoutable. The class consisted of Dévastation and Courbet.
The Duilio class was a pair of ironclad turret ships built for the Royal Italian Navy in the 1870s and 1880s. The two ships, Duilio and Enrico Dandolo, were fitted with the largest guns available, 450 mm (17.7 in) rifled muzzle-loading guns, and were the largest, fastest and most powerful ships of their day. To save weight on such large vessels, the ship's designer, Benedetto Brin adopted a radical solution for the time: he reserved armor only for the central portion of the ship where it protected the ships' engines and ammunition magazines, while the rest of the hull were extensively sub-divided with watertight compartments.
SS John Burke was an American Liberty Ship built during World War II, one of the 2,710 type 'EC2-S-C1' ships that carried all kinds and types of dry cargo during the war. The ship was named for John Burke, the 10th Governor of North Dakota. Burke was built at Kaiser Shipbuilding Company's Oregon Shipbuilding yard in Portland, Oregon. Burke's keel was laid November 20, 1942 and the hull was launched on December 13. After fitting-out, Burke was delivered to the US Maritime Commission on December 23, just 33 days after construction began. The War Shipping Administration then placed Burke under management of the Northland Transportation Company.
SS William S. Ladd was an American Liberty ship built during World War II, one of the 2,710 type 'EC2-S-C1' ships that carried all kinds and types of dry cargo during the war. She was named for William S. Ladd, an American politician and businessman in Oregon, who twice served as Portland's mayor in the 1850s. The ship's keel was laid on August 29, 1943, and 15 days later, on September 13, the hull was launched. William S. Ladd was fitted out in seven days, and was delivered to the U.S. Navy on September 20. The Navy placed Ladd under charter to Weyerhaeuser Steamship Co.
Dupetit-Thouars was a Gueydon-class armoured cruiser of the French Navy. She was torpedoed and sunk on 7 August 1918 by SM U-62 with the loss of 13 of her crew.
The Friant class comprised three protected cruisers of the French Navy built in the early 1890s; the three ships were Friant, Bugeaud, and Chasseloup-Laubat. They were ordered as part of a naval construction program directed at France's rivals, Italy and Germany, particularly after Italy made progress in modernizing its own fleet. The plan was also intended to remedy a deficiency in cruisers that had been revealed during training exercises in the 1880s. As such, the Friant-class cruisers were intended to operate as fleet scouts and in the French colonial empire. The ships were armed with a main battery of six 164 mm (6.5 in) guns supported by four 100 mm (3.9 in) guns and they had a top speed of 18.7 knots.
The Jean Bart class comprised two protected cruisers of the French Navy built in the late 1880s and early 1890s; the two ships were Jean Bart and Isly. They were ordered as part of a fleet program that accorded with the theories of the Jeune École, which proposed a fleet based on cruisers and torpedo boats to defend France. The Jean Bart-class cruisers were intended to serve a long-range commerce raiders to attack enemy merchant shipping. The ships were armed with a main battery of four 164 mm (6.5 in) guns supported by six 138 mm (5.4 in) guns and they had a top speed of 19 to 19.5 knots.
Sfax was a protected cruiser built for the French Navy in the 1880s. She was the first vessel of the type to be built for the French Navy, which was a development from earlier unprotected cruisers like Milan. Unlike the earlier vessels, Sfax carried an armor deck that covered her propulsion machinery and ammunition magazines. Intended to be used as a commerce raider in the event of war with Great Britain, Sfax was rigged as a barque to supplement her engines on long voyages abroad. She was armed with a main battery of six 164 mm (6.5 in) guns and a variety of lighter weapons.
Suchet was a protected cruiser of the French Navy built in the late 1880s and early 1890s. The ship was ordered during the tenure of Admiral Théophile Aube as the French Minister of Marine, who favored a fleet centered on large numbers of cruisers of various types. Suchet and the similar vessel Davout were ordered to fill the role of a medium cruiser in Aube's plans; the two cruisers were meant to be identical, but problems during Davout's construction forced design changes to Suchet, resulting in two unique vessels rather than a single class. Suchet was armed with a main battery of six 164 mm (6.5 in) guns in individual mounts and had a top speed of 20.4 knots.
Amiral Tréhouart was the second and last Bouvines-class ironclad coast-defence ships built for the French Navy in the early 1890s. Completed in 1896, little is known about her service. During World War I, the ship served as a submarine tender. She was sold for scrap in 1920.
The Aurora class was a group of screw corvettes built for the Austro-Hungarian Navy in the early 1870s. The class comprised three ships: SMS Aurora, Frundsberg, and Zrinyi.
