Bismarck was the first of two Bismarck-class battleships built for Nazi Germany's Kriegsmarine. Named after Chancellor Otto von Bismarck, the ship was laid down at the Blohm & Voss shipyard in Hamburg in July 1936 and launched in February 1939. Work was completed in August 1940, when she was commissioned into the German fleet. Bismarck and her sister ship Tirpitz were the largest battleships ever built by Germany, and two of the largest built by any European power.
The North Carolina class were a pair of fast battleships, North Carolina and Washington, built for the United States Navy in the late 1930s and early 1940s.
The King George V-class battleships were the most modern British battleships in commission during the Second World War. Five ships of this class were built: HMS King George V, HMS Prince of Wales (1941), HMS Duke of York (1941), HMS Anson (1942) and HMS Howe (1942). The names honoured King George V, and his sons, Edward VIII, who had been Prince of Wales, and George VI who was Duke of York before ascending to the throne; the final two ships of the class were named after prominent 18th century admirals of the Royal Navy.
HMS King George V was the lead ship of the five British King George V-class battleships of the Royal Navy. Laid down in 1937 and commissioned in 1940, King George V operated during the Second World War in all three major naval theatres of war, the Atlantic, Mediterranean and Pacific, as well as part of the British Home Fleet and Pacific Fleets. In May 1941, along with HMS Rodney, King George V was involved in the hunt for and pursuit of the German battleship Bismarck, eventually inflicting severe damage which led to the German vessel's sinking. On 1 May 1942 the destroyer HMS Punjabi sank after a collision with King George V in foggy conditions. King George V took part in Operation Husky and bombarded the island of Levanzo and the port of Trapani. She also escorted part of the surrendered Italian Fleet, which included the battleships Andrea Doria and Duilio, to Malta. In 1945 King George V took part in operations against the Japanese in the Pacific.
HMS Duke of York was a King George V-class battleship of the Royal Navy. Laid down in May 1937, the ship was constructed by John Brown and Company at Clydebank, and commissioned into the Royal Navy on 4 November 1941, subsequently seeing combat service during the Second World War. In mid-December 1941, Duke of York transported Prime Minister Winston Churchill to the United States to meet President Franklin D. Roosevelt. Between March and September 1942 Duke of York was involved with convoy escort duties, including as flagship of the Heavy Covering Force of Convoy PQ-17, but in October she was dispatched to Gibraltar where she became the flagship of Force H.
HMS Anson was a King George V-class battleship of the Royal Navy, named after Admiral George Anson. She was built by Swan Hunter and Wigham Richardson Shipyard on the River Tyne and launched on 24 February 1940, being completed on 22 June 1942. Her completion was delayed to allow the fitting of fire-control radar and additional anti-aircraft weapons. She was originally to have been named Jellicoe, but was renamed Anson in February 1940.
HMS Howe was the last of the five British King George V-class battleships of the Royal Navy. Built by Fairfield Shipbuilding and Engineering Company, she was laid down on 1 June 1937 and launched 9 April 1940. She was originally to have been named Beatty but this was changed to Howe, after Admiral Richard Howe.
HMS Vanguard was a British fast battleship built during the Second World War and commissioned after the war ended. She was the largest and fastest of the Royal Navy's battleships, and the only ship of her class. Vanguard was the last battleship to be built in history.
The Scharnhorst class was a class of German battleships built immediately prior to World War II. The first capital ships of Nazi Germany's Kriegsmarine, it comprised two vessels: Scharnhorst and Gneisenau. Scharnhorst was launched first, and is considered to be the lead ship by some sources; they are also referred to as the Gneisenau class in some other sources, as Gneisenau was the first to be laid down and commissioned. They marked the beginning of German naval rearmament after the Treaty of Versailles. The ships were armed with nine 28 cm (11 in) SK C/34 guns in three triple turrets; plans to replace these with six 38 cm (15 in) SK C/34 guns in twin turrets were never realized.
The Lion class was a class of six fast battleships designed for the Royal Navy (RN) in the late 1930s. They were a larger, improved version of the preceding King George V class, with 16-inch (406 mm) guns. Only two ships were laid down before the Second World War began in September 1939 and a third was ordered during the war, but their construction was suspended shortly afterwards. The design was modified in light of war experience in 1942, but the two ships already begun were scrapped later in the year.
The BL 15-inch Mark I succeeded the BL 13.5-inch Mk V naval gun. It was the first British 15-inch (380 mm) gun design and the most widely used and longest lasting of any British designs, and arguably the most successful heavy gun ever developed by the Royal Navy. It was deployed on capital ships from 1915 until 1959 and was a key Royal Navy gun in both World Wars.
The P class was a planned group of twelve heavy cruisers of Nazi Germany's Kriegsmarine; they were the successor to the Deutschland-class cruisers. Design work began in 1937 and continued until 1939; at least twenty designs were submitted with nine of them being considered. There were three designs that were selected as the final contenders. One design was armed with six 283mm main guns in one triple turret forward and one more turret aft. It had two 150mm double secondary gun turrets as secondary armament with one being positioned above and just fore of the aft of the main 283mm main turret, and the other being in front and lower of the front main gun turret. This design had more beam than the other 2 designs. It also mounted 2 seaplanes on its fantail instead of the mid ship area. The final design was armed with six 28 cm (11 in) quick-firing guns in two triple turrets, as in the preceding Deutschland class. The ships were designated as Panzerschiff, and given the preliminary names P1–P12. They were an improved design over the preceding planned D-class cruisers, which had been canceled in 1934. Although the ships were already assigned to shipyards, construction never began on the P-class ships after the O-class battlecruiser design superseded them.
The 38 cm SK C/34 naval gun was developed by Germany in the late 1930s. It armed the Bismarck-class battleships and was planned as the armament of the O-class battlecruisers and the re-armed Scharnhorst-class battleships. Six twin-gun mountings were also sold to the Soviet Union and it was planned to use them on the Kronshtadt-class battlecruisers, however, they were never delivered. Spare guns were used as coastal artillery in Denmark, Norway and France. One gun and one barrel is currently on display at respectively Møvig Fortress outside Kristiansand and Bunkermuseum Hanstholm, Denmark.
The BL 6-inch gun Mark VII was a British naval gun dating from 1899, which was mounted on a heavy travelling carriage in 1915 for British Army service to become one of the main heavy field guns in the First World War, and also served as one of the main coast defence guns throughout the British Empire until the 1950s.
The Armstrong Whitworth 12-inch naval gun of 40 calibres length was designed by and manufactured mainly by Armstrong's ordnance branch, Elswick Ordnance Company. It was intended for the Royal Navy's Royal Sovereign-class battleships, but budgetary constraints delayed their introduction. The first units were instead supplied to Japan. As the Type 41 12-inch (305 mm) 40-calibre naval gun it was the standard main battery on several early United Kingdom-built pre-dreadnought battleships of the Imperial Japanese Navy.
The QF 5.25-inch Mark I gun was the heaviest dual-purpose gun used by the Royal Navy during the Second World War. Although considered less than completely successful, it saw extensive service. 267 guns were built.
The D-class cruisers were a pair of German heavy cruisers, classified as panzerschiffe by the Reichsmarine. The ships were improved versions of the preceding Deutschland-class cruisers, authorized by Adolf Hitler in 1933. They were intended to counter a new French naval construction program. Displacement increased to 20,000 long tons (20,000 t), but Hitler allowed only increases to armor, prohibiting additions to the ships' main battery armament. Both ships were laid down in February 1934, but not much work done before work was cancelled pending a significant revision of the design. It was determined that the ships should be enlarged to counter the new French Dunkerque-class battleship. The construction contracts for both ships were superseded by the Scharnhorst-class battleships.
The Bismarck class was a pair of fast battleships built for Nazi Germany's Kriegsmarine shortly before the outbreak of World War II. The ships were the largest and most powerful warships built for the Kriegsmarine; displacing more than 41,000 metric tons normally, they were armed with a battery of eight 38 cm (15 in) guns and were capable of a top speed of 30 knots. Bismarck was laid down in July 1936 and completed in September 1940, while the keel of her sister ship, Tirpitz, was laid in October 1936 and work finished in February 1941. The ships were ordered in response to the French Richelieu-class battleships, themselves laid down in response to the Italian Littorio-class battleships. The Bismarck-class was designed with the traditional role of engaging enemy battleships in home waters in mind, though the Oberkommando der Marine envisioned employing the ships as long-range commerce raiders against British shipping in the Atlantic Ocean. As such, their design represented the strategic confusion that dominated German naval construction in the 1930s.
Scharnhorst was a German capital ship, alternatively described as a battleship or battlecruiser, of Nazi Germany's Kriegsmarine. She was the lead ship of her class, which included her sister ship Gneisenau. The ship was built at the Kriegsmarinewerft dockyard in Wilhelmshaven; she was laid down on 15 June 1935 and launched a year and four months later on 3 October 1936. Completed in January 1939, the ship was armed with a main battery of nine 28 cm (11 in) C/34 guns in three triple turrets. Plans to replace these weapons with six 38 cm (15 in) SK C/34 guns in twin turrets were never carried out.
The H class was a series of battleship designs for Nazi Germany's Kriegsmarine, which were intended to fulfill the requirements of Plan Z in the late 1930s and early 1940s. The first variation, "H-39", called for six ships to be built, essentially as enlarged Bismarck-class battleships with 40.6 cm (16 in) guns and diesel propulsion. The "H-41" design improved the "H-39" ship with still larger main guns, eight 42 cm (16.5 in) weapons, and reinforced deck armor. The Construction Office of the Oberkommando der Marine (OKM) concluded their work with the "H-41" design, and were not involved in subsequent plans. Two of them, "H-42" and "H-43", increased the main battery yet again, with 48 cm (18.9 in) pieces, and the enormous "H-44" design ultimately resulted with 50.8 cm (20 in) guns. The ships ranged in size from the "H-39", which was 277.8 m long on a displacement of 56,444 t, to the "H-44", at 345 m on a displacement of 131,000 t. Most of the designs had a proposed top speed in excess of 30 knots (56 km/h).
