HMS Agincourt (1913)
HMS ''Agincourt'' was a dreadnought battleship built in the United Kingdom in the early 1910s. Originally part of Brazil's role in a South American naval arms race, she holds the distinction of mounting more heavy guns (fourteen) and more turrets (seven) than any other dreadnought battleship, in keeping with the Brazilians' requirement for an especially impressive design. Brazil ordered the ship in 1911 as ''Rio de Janeiro'' from the British company Armstrong Whitworth. However, the collapse of Brazil's rubber boom and a warming in relations with Argentina, the country's chief rival, led to the ship's sale while under construction to the Ottoman Empire. The Ottomans renamed her ''Sultan Osman I'', after the empire's founder, and the ship was nearly complete when the First World War broke out. The British government seized her for use by the Royal Navy, together with another Ottoman dreadnought being constructed in Britain. This act caused resentment in the Ottoman Empire, a ...

Belt Armor
Belt armor is a layer of heavy metal armor plated onto or within the outer hulls of warships, typically on battleships, battlecruisers and cruisers, and aircraft carriers. The belt armor is designed to prevent projectiles from penetrating to the heart of a warship. When struck by an artillery shell or underwater torpedo, the belt armor either absorbs the impact and explosion with its sheer thickness and strength, or else uses sloping to redirect the projectile and its blast downwards. Typically, the main armor belt covers the warship from its main deck down to some distance below the waterline. If, instead of forming the outer hull, the armor belt is built inside the hull, it is installed at a sloped angle for improved protection, as described above. The torpedo bulkhead Frequently, the main belt's armor plates were supplemented with a torpedo bulkhead spaced several meters behind the main belt, designed to maintain the ship's watertight integrity even if the main belt ...

Central Powers
The Central Powers, also known as the Central Empires,german: Mittelmächte; hu, Központi hatalmak; tr, İttifak Devletleri / ; bg, Централни сили, translit=Tsentralni sili was one of the two main coalitions that fought in World War I (1914–1918). It consisted of the German Empire, Austria-Hungary, the Ottoman Empire, and the Kingdom of Bulgaria and was also known as the Quadruple Alliance.german: Vierbund, tr, Dörtlü İttifak, hu, Központi hatalmak, bg, Четворен съюз, translit=Chetvoren sūyuz Colonies of these countries also fought on the Central Powers' side such as German New Guinea and German East Africa, until almost all of their colonies were occupied by the Allies. The Central Powers faced and were defeated by the Allied Powers that had formed around the Triple Entente. The Central Powers' origin was the alliance of Germany and Austria-Hungary in 1879. Despite having nominally joined the Triple Alliance before, Italy d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Erin
HMS ''Erin'' was a dreadnought battleship of the Royal Navy, originally ordered by the Ottoman government from the British Vickers Company. The ship was to have been named ''Reşadiye'' when she entered service with the Ottoman Navy. The was designed to be at least the equal of any other ship afloat or under construction. When the First World War began in August 1914, ''Reşadiye'' was nearly complete and was seized at the orders of Winston Churchill, the First Lord of the Admiralty, to keep her in British hands and prevent her from being used by Germany or German allies. There is no evidence that the seizure played any part in the Ottoman government declaring war on Britain and the Triple Entente. Aside from a minor role in the Battle of Jutland in May 1916 and the inconclusive Action of 19 August the same year, ''Erin''s service during the war generally consisted of routine patrols and training in the North Sea. The ship was deemed obsolete after the war; she was reduce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rubber Boom
The Amazon rubber boom ( pt, Ciclo da borracha, ; es, Fiebre del caucho, , 1879 to 1912) was an important part of the economic and social history of Brazil and Amazonian regions of neighboring countries, being related to the extraction and commercialization of rubber. Centered in the Amazon Basin, the boom resulted in a large expansion of European colonization in the area, attracting immigrant workers, generating wealth, causing cultural and social transformations, and wreaking havoc upon indigenous societies. It encouraged the growth of cities such as Manaus and Belém, capitals within the respective Brazilian states of Amazonas and Pará, among many other cities throughout the region like Itacoatiara, Rio Branco, Eirunepé, Marabá, Cruzeiro do Sul and Altamira; as well as the expansion of Iquitos in Peru, Cobija in Bolivia and Leticia in Colombia. The rubber boom occurred largely between 1879 and 1912. There was heightened rubber production and associated activiti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South American Dreadnought Race
A naval arms race among Argentina, Brazil and Chile—the wealthiest and most powerful countries in South America—began in the early twentieth century when the Brazilian government ordered three dreadnoughts, formidable battleships whose capabilities far outstripped older vessels in the world's navies. In 1904, the Brazilian legislature allocated substantial funds to improve the country's naval forces. The plan's proponents believed that a strong navy was a requirement in becoming an international power, and was needed to combat recent naval expansions in Argentina and Chile. The revolutionary design of the 1906 British warship induced the Brazilians to alter these plans, redirecting their money into constructing three larger dreadnoughts; two were constructed immediately. These warships, the most powerful in the world, entered service at a time when dreadnoughts were a measure of international prestige. They therefore brought global attention to what was perceived to be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dreadnought Battleship
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 Causes of World War I#Arms race, naval arms race between the Anglo–German naval arms race, United Kingdom and Germany. Dreadnought races sprang up around the world, including South American dreadnought race, 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulkhead (partition)
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an airplane. Other kinds of partition elements within a ship are decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkhead partitions are considered to have been a feature of Chinese junks, a type of ship. Song Dynasty author Zhu Yu (fl. 12th century) wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book ''Garden of Strange Things'' by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking. Archaeolo ...

Conning Tower
A conning tower is a raised platform on a ship or submarine, often armored, from which an officer in charge can conn the vessel, controlling movements of the ship by giving orders to those responsible for the ship's engine, rudder, lines, and ground tackle. It is usually located as high on the ship as practical, to give the conning team good visibility of the entirety of the ship, ocean conditions, and other vessels. The naval term "conn" may derive from the Middle English ''conne'' (study, become acquainted with) or French ''conduire'' from Latin ''conducere'' (conduct). Surface ships On surface ships, the conning tower was a feature of all battleships and armored cruisers from about 1860 to the early years of World War II. Located at the front end of the superstructure, the conning tower was a heavily armored cylinder, with tiny slit windows on three sides providing a reasonable field of view. Designed to shield just enough personnel and devices for navigation during battle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
