French Ironclad Redoutable
''Redoutable'' was a central battery and barbette ship of the French Navy. She was the first warship in the world to use steel as the principal building material.Conway Marine, 'Steam, Steel, and Shellfire" She was preceded by the ''Colbert''-class ironclads and was succeeded by ''Dévastation''-class. Compared to iron, steel allowed for greater structural strength for a lower weight. France was the first country to manufacture steel in large quantities, using the Siemens process. At that time, steel plates still had some defects, and the outer bottom plating of the ship was made of wrought iron. All-steel warships were later built by the Royal Navy, with the dispatch vessels '' Iris'' and ''Mercury'', laid down in 1875–1876.

Wrought Iron
Wrought iron is an iron alloy with a very low carbon content (less than 0.08%) in contrast to that of cast iron (2.1% to 4%). It is a semi-fused mass of iron with fibrous slag inclusions (up to 2% by weight), which give it a wood-like "grain" that is visible when it is etched, rusted, or bent to failure. Wrought iron is tough, malleable, ductile, corrosion resistant, and easily forge welded, but is more difficult to weld electrically. Before the development of effective methods of steelmaking and the availability of large quantities of steel, wrought iron was the most common form of malleable iron. It was given the name ''wrought'' because it was hammered, rolled, or otherwise worked while hot enough to expel molten slag. The modern functional equivalent of wrought iron is mild steel, also called low-carbon steel. Neither wrought iron nor mild steel contain enough carbon to be hardenable by heating and quenching. Wrought iron is highly refined, with a small amount of silic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built In France
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% w ...

Barbette
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. ...

Qing Dynasty
The Qing dynasty ( ), officially the Great Qing,, was a Manchu-led imperial dynasty of China and the last orthodox dynasty in Chinese history. It emerged from the Later Jin dynasty founded by the Jianzhou Jurchens, a Tungusic-speaking ethnic group who unified other Jurchen tribes to form a new "Manchu" ethnic identity. The dynasty was officially proclaimed in 1636 in Manchuria (modern-day Northeast China and Outer Manchuria). It seized control of Beijing in 1644, then later expanded its rule over the whole of China proper and Taiwan, and finally expanded into Inner Asia. The dynasty lasted until 1912 when it was overthrown in the Xinhai Revolution. In orthodox Chinese historiography, the Qing dynasty was preceded by the Ming dynasty and succeeded by the Republic of China. The multiethnic Qing dynasty lasted for almost three centuries and assembled the territorial base for modern China. It was the largest imperial dynasty in the history of China and in 1790 ...

Boxer Protocol
The Boxer Protocol was signed on September 7, 1901, between the Qing Empire of China and the Eight-Nation Alliance that had provided military forces (including Austria-Hungary, France, Germany, United Kingdom, Italy, Japan, Russia, and the United States as well as Belgium, Spain, and the Netherlands), after China's defeat in the intervention to put down the Boxer Rebellion. It is regarded as one of the unequal treaties. Negotiations during the Boxer Rebellion The Qing dynasty was by no means defeated when the Allies took control of Beijing. The Allies had to temper the demands they sent in a message to Xi'an to get the Empress Dowager Cixi to agree with them; for instance, China did not have to give up any land. Many of the Dowager Empress' advisers in the Imperial Court insisted that the war continue against the foreigners, arguing that China could defeat them since it was the disloyal and traitorous people within China who allowed Beijing and Tianjin to be captured by the A ...

Hotchkiss Gun
The Hotchkiss gun can refer to different products of the Hotchkiss arms company starting in the late 19th century. It usually refers to the 1.65-inch (42 mm) light mountain gun; there were also a navy (47 mm) and a 3-inch (76 mm) Hotchkiss guns. The 42 mm gun was intended to be mounted on a light carriage or packed on two mules to accompany a troop of cavalry or an army travelling in rough country. Descriptions 1.65-inch gun The gun and accessories could be packed on two mules. The gun was introduced as a modern replacement for the aging twelve-pounder mountain howitzer. The first gun purchased by the U.S. military from the French arms firm of Hotchkiss was employed against the Nez Percé in 1877. Over the next twenty years the U.S. purchased 56. They were used at the Wounded Knee Massacre in 1890, and again in Cuba at the Battle of Las Guasimas, the Battle of El Caney and the attack on San Juan Hill during the Spanish–American War of 1898. ...

Torpedo Nets
Torpedo nets were a passive ship defensive device against torpedoes. They were in common use from the 1890s until the Second World War. They were superseded by the anti-torpedo bulge and torpedo belts. Origins With the introduction of the Whitehead torpedo in 1873, and the subsequent development of the torpedo boat, new means were sought to protect capital ships against underwater attacks. In 1876 the British Admiralty Torpedo Committee came up with a number of recommendations for combating torpedoes, which included "... nets of galvanised iron hung around each battleship from projecting 40 ft spars". Experiments were conducted in 1877, with becoming the first operational ship to be fitted with the nets. Design and use Torpedo nets could be hung out from the defending ship, when moored or otherwise stationary in the water, on multiple horizontal booms. Each boom was fixed to the ship at one end at or below the edge of the main deck, by a steel pin that permitted the boom to ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the ...
