Marceau-class Ironclad
The ''Marceau'' class was group of three of ironclad warship, ironclad barbette ships of the French Navy built in the 1880s and early 1890s. The class comprised , the lead ship, , and ; a fourth member of the class, was substantially re-designed after defects in the original plans for the class could not be rectified. The ships were based on the earlier of barbette ships, but with smaller guns: four weapons compared to the three guns of the earlier vessels. They introduced the Lozenge (shape), lozenge arrangement for their main battery that became common for many French capital ships built in the 1890s. Continuous tinkering with the ''Marceau'' design during their long construction produced badly flawed vessels that were superseded by more powerful pre-dreadnought battleships almost immediately after the French ship commissioning, commissioned them in the early 1890s. The three ships served in the Mediterranean Squadron (France), Mediterranean Squadron in the 1890s and saw l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barbette Ship
Barbettes are several types of gun emplacement in terrestrial fortifications or on naval ships. In recent naval usage, a barbette is a protective circular armour support for a heavy gun turret. This evolved from earlier forms of gun protection that eventually led to the pre-dreadnought. The name ''barbette'' ultimately comes from fortification - it originally meant a raised platform or mound, as in the French phrase ''en barbette'', which refers to the practice of firing a cannon over a parapet rather than through an embrasure in a fortification's casemate. The former gives better angles of fire but less protection than the latter. The disappearing gun was a variation on the barbette gun; it consisted of a heavy gun on a carriage that would retract behind a parapet or into a gunpit for reloading. Barbettes were primarily used in coastal defences, but saw some use in a handful of warships, and some inland fortifications. The term is also used for certain aircraft gun mounts. ...

Lead Ship
The lead ship, name ship, or class leader is the first of a series or class of ships all constructed according to the same general design. The term is applicable to naval ships and large civilian vessels. Large ships are very complex and may take as many as five to ten years to build. Improvements based on experience with building and operating the lead ship are likely to be incorporated into the design or construction of later ships in the class, so it is rare to have vessels that are identical. The second and later ships are often started before the first one is completed, launched and tested. Nevertheless, building copies is still more efficient and cost-effective than building prototypes, and the lead ship will usually be followed by copies with some improvements rather than radically different versions. The improvements will sometimes be retrofitted to the lead ship. Occasionally, the lead ship will be launched and commissioned for shakedown testing before following ship ...

Bizerte
Bizerte or Bizerta ( ar, بنزرت, translit=Binzart , it, Biserta, french: link=no, Bizérte) the classical Hippo, is a city of Bizerte Governorate in Tunisia. It is the northernmost city in Africa, located 65 km (40mil) north of the capital Tunis.

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 ...

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] |
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.

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

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] |
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. History Mediterranean Squadron Vice-amiral François Fournier was Commander-in-Chief, Mediterranean Squadron (''Commandant e ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
