French Ironclad Magenta (1890)
''Magenta'' was an ironclad barbette ship of the French Navy built in the 1880s and early 1890s. She was the third and final member of the . The ''Marceau'' class was based on the earlier of barbette ships, but with smaller guns: four weapons compared to the three guns of the earlier vessels. The ships introduced the lozenge arrangement for their main battery that became common for many French capital ships built in the 1890s. ''Magenta'' and her sister ships suffered from a number of problems, including poor stability, insufficient armor protection, and excessive displacement. ''Magenta'', completed in 1893, had a relatively short and uneventful career, which she spent in the Mediterranean Squadron conducting training exercises. New pre-dreadnought battleships began to enter service in the mid-1890s, which displaced the ''Marceau''s to the Reserve Division, where they were used as training ships. ''Magenta'' and her sisters were scheduled to be modernized with new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lozenge (shape)
A lozenge ( ; symbol: ), often referred to as a diamond, is a form of rhombus. The definition of ''lozenge'' is not strictly fixed, and the word is sometimes used simply as a synonym () for ''rhombus''. Most often, though, lozenge refers to a thin rhombus—a rhombus with two acute and two obtuse angles, especially one with acute angles of 45°. The lozenge shape is often used in parquetry (with acute angles that are 360°/''n'' with ''n'' being an integer higher than 4, because they can be used to form a set of tiles of the same shape and size, reusable to cover the plane in various geometric patterns as the result of a tiling process called tessellation in mathematics) and as decoration on ceramics, silverware and textiles. It also features in heraldry and playing cards. Symbolism The lozenge motif dates from the Neolithic and Paleolithic period in Eastern Europe and represents a sown field and female fertility. The ancient lozenge pattern often shows up in Diamond vault ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Ironclad Warship
An ironclad is a steam-propelled warship protected by iron or steel armor plates, constructed from 1859 to the early 1890s. The ironclad was developed as a result of the vulnerability of wooden warships to explosive or incendiary shells. The first ironclad battleship, , was launched by the French Navy in November 1859 - narrowly pre-empting the British Royal Navy. They were first used in warfare in 1862 during the American Civil War, when ironclads operated against wooden ships and, in a historic confrontation, against each other at the Battle of Hampton Roads in Virginia. Their performance demonstrated that the ironclad had replaced the unarmored ship of the line as the most powerful warship afloat. Ironclad gunboats became very successful in the American Civil War. Ironclads were designed for several uses, including as high seas battleships, long-range cruisers, and coastal defense ships. Rapid development of warship design in the late 19th century transformed the ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaker
''Ship Breaker'' is a 2010 young adult novel by Paolo Bacigalupi set in a post-apocalyptic future. Human civilization is in decline for ecological reasons. The polar ice caps have melted and New Orleans is underwater. On the Gulf Coast nearby, humanity has reverted to survival mode and a small economy has grown from the scavenging of washed up oil tankers for bits of copper and other valuables. Nailer is a fifteen-year-old boy who works on the light crew. His mother died when he was a young boy and he now lives with his alcoholic and drug addicted father, Richard Lopez. After a storm, Nailer rescues Nita, the stranded daughter of a wealthy merchant, and helps her to get back home. This infuriates several parties, including Nailer's father, the local power brokers, and Nita's father's enemies, including Nita's uncle Pyce. Plot Nailer, a small-framed teenage boy, is scavenging through an old rusty ship for copper wire. As he crawls through the darkness looking for scavenge ...

Naval Register
A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval authorities of a country. Background The Navy List fulfills an important function in international law in that warships are required by article 29 of the United Nations Convention on the Law of the Sea to be commanded by a commissioned officer whose name appears in the appropriate service list. Past copies of the Navy List are also important sources of information for historians and genealogists. The Navy List for the Royal Navy is no longer published in hard-copy. The Royal Navy (United Kingdom) publishes annual lists of active and reserve officers, and biennial lists of retired officers. As of 2015, the Navy List of the Royal Navy has been renamed as the 'Navy Directory'. The equivalent in the United States Navy is the Naval Register, whic ...

Water-tube Boiler
A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. The heated water/steam mixture then rises into the steam drum. Here, saturated steam is drawn off the top of the drum. In some services, the steam passes through tubes in the hot gas path, (a superheater) to become superheated. Superheated steam is defined as steam that is heated above the boiling point at a given pressure. Superheated steam is a dry gas and therefore is typically used to drive turbines, since water droplets can severely damage turbine blades. Saturated water at the bottom of the steam drum returns to the lower drum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Training Ship
A training ship is a ship used to train students as sailors. The term is mostly used to describe ships employed by navies to train future officers. Essentially there are two types: those used for training at sea and old hulks used to house classrooms. The hands-on aspect provided by sail training has also been used as a platform for everything from semesters at sea for undergraduate oceanography and biology students, marine science and physical science for high school students, to character building for at-risk youths.

Pre-dreadnought Battleship
Pre-dreadnought battleships were sea-going battleships built between the mid- to late- 1880s and 1905, before the launch of in 1906. The pre-dreadnought ships replaced the ironclad battleships of the 1870s and 1880s. Built from steel, protected by case-hardened steel armour, and powered by coal-fired triple-expansion steam engines, pre-dreadnought battleships carried a main battery of very heavy guns in fully enclosed rotating turrets supported by one or more secondary batteries of lighter weapons. In contrast to the multifarious development of ironclad warships in preceding decades, the 1890s saw navies worldwide start to build battleships to a common design as dozens of ships essentially followed the design of the Royal Navy's . The similarity in appearance of battleships in the 1890s was underlined by the increasing number of ships being built. New naval powers such as Germany, Japan, the United States, and to a lesser extent Italy and Austria-Hungary, began to establish ...

Mediterranean Squadron (France)
The French Commander-in-Chief, Mediterranean, also known as CECMED (French for ''Commandant en chef pour la Méditerranée'') is a French Armed Forces regional commander. He commands the zone, the region and the Mediterranean maritime ''arrondissements''. He is usually an admiral of the French Navy, and is under the direct authority of the French Chief of the Defence Staff. the position was held by Admiral Yann Tainguy. CECMED today is simultaneously: * Commander of the région and the Mediterranean maritime ''arrondissement'', * Maritime Zone commander, * Maritime Prefect for the Méditerranean. Today the main French naval combat force in the Mediterranean is the Force d'action navale (FAN) headquartered at Toulon. The Admiral commanding the Naval Action Force (ALFAN) is responsible to the Chief of Staff of the French Navy at the rue Royale in Paris.

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...
