Superfiring
Superfiring armament is a naval military building technique in which two (or more) turrets are located in a line, one behind the other, with the second turret located above ("super") the one in front so that the second turret can fire over the first. This configuration meant that both forward or aft turrets could fire at any target within their sector, even when the target was in the same vertical plane as the turrets. History The history of large surface warships follow generic labels as battleships, and a further distinction between pre-dreadnoughts and dreadnoughts. The era of technical evolution occurred roughly from 1900 to 1945. Part of the technical evolution was driven by the need to compress as much large-gun firepower into the smallest space possible. In early designs, the large-caliber turrets were all located on the same plane firing to one side or the other. In firing ahead or to the rear, usually only the forward-most or rearmost turret could fire, especially a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreadnought
The dreadnought (alternatively spelled dreadnaught) was the predominant type of battleship in the early 20th century. The first of the kind, the Royal Navy's , had such an impact when launched in 1906 that similar battleships built after her were referred to as "dreadnoughts", and earlier battleships became known as pre-dreadnoughts. Her design had two revolutionary features: an "all-big-gun" armament scheme, with an unprecedented number of heavy-calibre guns, and steam turbine propulsion. As dreadnoughts became a crucial symbol of national power, the arrival of these new warships renewed the naval arms race between the United Kingdom and Germany. Dreadnought races sprang up around the world, including in South America, lasting up to the beginning of World War I. Successive designs increased rapidly in size and made use of improvements in armament, armour and propulsion throughout the dreadnought era. Within five years, new battleships outclassed ''Dreadnought'' herself. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Battleship Henri IV
''Henri IV'' was a pre-dreadnought battleship of the French Navy built to test some of the ideas of the prominent naval architect Louis-Émile Bertin. She began World War I as guardship at Bizerte. She was sent to reinforce the Allied naval force in the Dardanelles campaign of 1915, although some of her secondary armament had been removed for transfer to Serbia in 1914. Afterwards, she was relegated to second-line roles before being sent to Taranto as a depot ship in 1918. She was struck from the navy list in 1920 and scrapped the following year. Design ''Henri IV'' was designed by the famous French naval architect Louis-Émile Bertin to evaluate some of his ideas. She was designed to make her a small target and lacked most of the normal rear superstructure common to ships of her period, other than that needed to keep her rear turret from being washed out. Her rear hull had only of freeboard, although she was built up to the normal upper deck height amidships and at the bow for ...

Gangut-class Battleship
The ''Gangut''-class, also known as the ''Sevastopol''-class, were the first dreadnoughts built for the Imperial Russian Navy before World War I. They had a convoluted design history involving several British companies, evolving requirements, an international design competition, and foreign protests. Four ships were ordered in 1909, , , , and . Construction was delayed by financing problems until the Duma formally authorized the ships in 1911. They were delivered from December 1914 through January 1915, although they still needed work on the gun turrets and fire-control systems until mid-1915. Their role was to defend the mouth of the Gulf of Finland against the Germans, who never tried to enter, so the ships spent their time training and providing cover for minelaying operations. Their crews participated in the general mutiny of the Baltic Fleet after the February Revolution in 1917, and joined the Bolsheviks the following year. All of the dreadnoughts except for ''Petropavlovsk' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperatritsa Mariya-class Battleship
The ''Imperatritsa Mariya''-class (russian: Императрица Мария) battleships were the first dreadnoughts built for the Black Sea Fleet of the Imperial Russian Navy. All three ships were built in Nikolayev during World War I; two of the ships were built by the Rossud Dockyard and the third was built by the Associated Factories and Shipyards of Nikolayev (russian: ONZiV). Two ships were delivered in 1915 and saw some combat against ex-German warships that had been 'gifted' to the Ottoman Empire, but the third was not completed until 1917 and saw no combat due to the disorder in the navy after the February Revolution earlier that year. was sunk by a magazine explosion in Sevastopol harbor in 1916. , having been renamed ''Svobodnaya Rossiya'' in 1917, was scuttled in Novorossiysk harbor in 1918 to prevent her from being turned over to the Germans as required by the Treaty of Brest-Litovsk. The crew of ''Volia'', as had been renamed in 1917, voted to turn her o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlanta-class Cruiser
The ''Atlanta''-class cruisers were eight United States Navy light cruisers which were designed as fast scout cruisers or flotilla leaders but which proved to be effective anti-aircraft cruisers during World War II. They were also known as the ''Atlanta''-''Oakland'' class. The ''Atlanta'' class had 12 x /38 caliber guns, mounted in three superfiring sets of two-gun turrets fore and three more aft. The first four ships of the class also had an additional two twin 5-inch/38 mounts, one port and one starboard, giving these first four ''Atlanta''-class cruisers the heaviest anti-aircraft armament of any cruiser of World War II. The last four ships of the class, starting with , had slightly different armament as they were further optimized for anti-aircraft fire. The ''Atlanta'' class saw heavy action during World War II, collectively earning 54 battle stars. Two ships of the class were sunk in action: and , both at the Naval Battle of Guadalcanal. The other six were decommission ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zumwalt-class Destroyer
The ''Zumwalt''-class destroyer is a class of three United States Navy guided-missile destroyers designed as multi-mission stealth ships with a focus on land attack. It is a multi-role class that was designed with a primary role of naval gunfire support and secondary roles of surface warfare and anti-aircraft warfare. The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)" and was intended to take the role of battleships in meeting a congressional mandate for naval fire support. The ship is designed around its two Advanced Gun Systems (AGS), turrets with 920 round magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was canceled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare. Starting in 2023, the Navy will remove the AGS from the ships and replace them with hypersonic missiles. These ships are classed as destroyers, but they are much larger than any other active destroyers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Russian Navy
The Imperial Russian Navy () operated as the navy of the Russian Tsardom and later the Russian Empire from 1696 to 1917. Formally established in 1696, it lasted until dissolved in the wake of the February Revolution of 1917. It developed from a smaller force that had existed prior to Tsar Peter the Great's founding of the modern Russian navy during the Second Azov campaign in 1696. It expanded in the second half of the 18th century and reached its peak strength by the early part of the 19th century, behind only the British and French fleets in terms of size. The Imperial Navy drew its officers from the aristocracy of the Empire, who belonged to the state Russian Orthodox Church. Young aristocrats began to be trained for leadership at a national naval school. From 1818 on, only officers of the Imperial Russian Navy were appointed to the position of Chief Manager of the Russian-American Company, based in Russian America (present-day Alaska) for colonization and fur-trade developme ...

Russian Battleship Imperator Nikolai I (1916)
''Imperator Nikolai I'' (russian: Император Николай I: ''Emperor Nicholas I'') was a Russian dreadnought built during World War I for service in the Black Sea. She was designed to counter multiple prospective Ottoman dreadnoughts which had been placed under order by the Ottoman government, since this raised the possibility that the Russian dreadnoughts being built for the Black Sea Fleet could be outclassed. The ship used the same main armament as the preceding , but was larger and more heavily armored. ''Imperator Nikolai I'' was launched in 1916, but construction was suspended on 24 October 1917. The Soviets considered completing her in 1923, but later rejected the idea. She was towed to Sevastopol in 1927 and scrapped. Design and development ''Imperator Nikolai I'' was designed in response to efforts by the Ottoman Empire to acquire modern dreadnoughts from abroad. By late 1913 it appeared that the Turks would be able to muster three dreadnoughts, two of whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metacentric Height
The metacentric height (GM) is a measurement of the initial static stability of a floating body. It is calculated as the distance between the centre of gravity of a ship and its metacentre. A larger metacentric height implies greater initial stability against overturning. The metacentric height also influences the natural period of rolling of a hull, with very large metacentric heights being associated with shorter periods of roll which are uncomfortable for passengers. Hence, a sufficiently, but not excessively, high metacentric height is considered ideal for passenger ships. Metacentre When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre. The metacentre remains directly above the centre of buoyancy by definition. In the diagra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
