Colossus-class Aircraft Carrier
The 1942 Design Light Fleet Carrier, commonly referred to as the British Light Fleet Carrier, was a light aircraft carrier design created by the Royal Navy during the Second World War, and used by eight naval forces between 1944 and 2001. They were designed and constructed by civilian shipyards to serve as an intermediate step between the expensive, full-size fleet aircraft carriers and the less expensive but limited-capability escort carriers. Sixteen Light Fleet carriers were ordered, and all were laid down to the ''Colossus'' class design during 1942 and 1943. However, only eight were completed to this design; of these, four entered service before the end of the war, and none saw front line operations. Two more were fitted with maintenance and repair facilities instead of aircraft catapults and arresting gear, and entered service as aircraft maintenance carriers. The final six were modified during construction to handle larger and faster aircraft, and were re-designated as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vietnam War
The Vietnam War (1 November 1955 – 30 April 1975) was an armed conflict in Vietnam, Laos, and Cambodia fought between North Vietnam (Democratic Republic of Vietnam) and South Vietnam (Republic of Vietnam) and their allies. North Vietnam was supported by the Soviet Union and China, while South Vietnam was supported by the United States and other anti-communist nations. The conflict was the second of the Indochina wars and a proxy war of the Cold War between the Soviet Union and US. The Vietnam War was one of the postcolonial wars of national liberation, a theater in the Cold War, and a civil war, with civil warfare a defining feature from the outset. Direct United States in the Vietnam War, US military involvement escalated from 1965 until its withdrawal in 1973. The fighting spilled into the Laotian Civil War, Laotian and Cambodian Civil Wars, which ended with all three countries becoming Communism, communist in 1975. After the defeat of the French Union in the First Indoc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flight Deck
The flight deck of an aircraft carrier is the surface on which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese ''Akagi'' and battleship ''Kaga'', were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner which entered service in 1918. The armoured flight deck was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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". A merchant vessel has t ...

Illustrious-class Aircraft Carrier
The ''Illustrious'' class was a class of aircraft carrier of the Royal Navy that included some of the most important British warships in the Second World War. They were laid down in the late 1930s as part of the rearmament of British forces in response to the emerging threats of Nazi Germany, Fascist Italy and Imperial Japan. The ''Illustrious'' class comprised four vessels: HM Ships ''Illustrious'', ''Formidable'', ''Victorious'' and ''Indomitable''. The last of these was built to a modified design with a second, half-length, hangar deck below the main hangar deck. Each of these ships played a prominent part in the battles of the Second World War. ''Victorious'' took part in the pursuit of the German battleship ''Bismarck'', ''Illustrious'' and ''Formidable'' played prominent parts in the battles in the Mediterranean during 1940 and 1941 and all three took part in the large actions of the British Pacific Fleet in 1945. The later two ships of the ''Implacable'' class w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vickers-Armstrong
Vickers-Armstrongs Limited was a British engineering conglomerate formed by the merger of the assets of Vickers Limited and Sir W G Armstrong Whitworth & Company in 1927. The majority of the company was nationalised in the 1960s and 1970s, with the remainder being divested as Vickers plc in 1977. It featured among Britain's most prominent armaments firms. History Vickers merged with the Tyneside-based engineering company Armstrong Whitworth, founded by William Armstrong, to become Vickers-Armstrongs. Armstrong Whitworth and Vickers had developed along similar lines, expanding into various military sectors and produced a whole suite of military products. Armstrong Whitworth were notable for their artillery manufacture at Elswick and shipbuilding at a yard at High Walker on the River Tyne. 1929 saw the merger of the acquired railway business with those of Cammell Laird to form Metropolitan Cammell Carriage and Wagon (MCCW); Metro Cammell. In 1935, before rearmament bega ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merchant Aircraft Carrier
A merchant aircraft carrier (also known as a MAC ship, the Admiralty (United Kingdom), Admiralty's official 'short name') was a limited-purpose aircraft carrier operated under British and Dutch civilian registry during World War II. MAC ships were adapted by adding a flight deck to a bulk grain ship or oil tanker enabling it to operate anti-submarine aircraft in support of Allies of World War II, Allied convoys during the Battle of the Atlantic. Despite their quasi-military function, MAC ships retained their mercantile status, continued to carry cargo and operated under civilian command. MAC ships entered service from May 1943 when they began to supplement and supplant escort carriers, and remained operational until the end of the war in Europe. Development In 1940, Captain M. S. Slattery RN, Director of Air Matériel at the Admiralty (United Kingdom), Admiralty, proposed a scheme for converting merchant ships into aircraft carriers as a follow-up to the CAM ship project.

Hawkins-class Cruiser
The ''Hawkins'' class consisted of five heavy cruisers built for the Royal Navy during the First World War, although none of them saw service during the war. The first ship to be completed, , was renamed from HMS ''Cavendish'' and converted into an aircraft carrier while under construction. All ships were named after Elizabethan sea captains. The three ships remaining as cruisers in 1939 served in the World War II, Second World War, with ''Effingham'' being an early war loss through wreck; ''Raleigh'' had been lost in a similar shipwreck on uncharted rocks in 1922 (and ''Vindictive'' was nearly lost to grounding in 1919). ''Vindictive'', though no longer a cruiser, also served throughout the War. This class formed the basis for the definition of the maximum cruiser type under the Washington Naval Treaty of 1922. Design Although the ''Hawkins'' class are sometimes named as the "Improved ''Birminghams''", referring to the ''Birmingham'' sub-class of the Town-class cruiser (1910), ...

Director Of Naval Construction
The Director of Naval Construction (DNC) also known as the Department of the Director of Naval Construction and Directorate of Naval Construction and originally known as the Chief Constructor of the Navy was a senior principal civil officer responsible to the Board of Admiralty for the design and construction of the warships of the Royal Navy. From 1883 onwards he was also head of the Royal Corps of Naval Constructors, the naval architects who staffed his department from 1860 to 1966. The (D.N.C.'s) modern equivalent is Director Ships in the Defence Equipment and Support organisation of the Ministry of Defence. History The post evolved from the office of the ''Assistant Surveyor of the Navy'' (1832–1859) In 1860 the ''Assistant Surveyor'' was renamed ''Chief Constructor'' the post lasted until 1875 when it was renamed to the ''Director of Naval Construction''. The chief constructor was originally head of the Royal Corps of Naval Constructors and members of the corps were res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Museum Ships
A museum ship, also called a memorial ship, is a ship that has been preserved and converted into a museum open to the public for educational or memorial purposes. Some are also used for training and recruitment purposes, mostly for the small number of museum ships that are still operational and thus capable of regular movement. Several hundred museum ships are kept around the world, with around 175 of them organised in the Historic Naval Ships AssociationAbout The Historic Naval Ships Association (the international website.

Brazilian Aircraft Carrier Minas Gerais
NAeL ''Minas Gerais'' (pennant number A 11) was a light aircraft carrier operated by the ''Marinha do Brasil'' (MB, Brazilian Navy) from 1960 until 2001. The ship was laid down for the United Kingdom's Royal Navy during World War II as , was completed shortly before the war's end, and did not see combat. After stints as a training vessel and Arctic research ship, the carrier was loaned to the Royal Australian Navy from 1952 to 1955. She was returned to the British, who sold her to Brazil in 1956. The ship underwent a four-year conversion in the Netherlands to make her capable of operating heavier naval aircraft. She was commissioned into the MB as ''Minas Gerais'' (named after the state of Minas Gerais) in 1960; the first purchased by a Latin American nation, and the second to enter service, behind the Argentinian ARA ''Independencia'' (also ''Colossus''-class). Between 1987 and 1996, the carrier was unable to operate fixed-wing aircraft because of a defective catapult, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaking
Ship breaking (also known as ship recycling, ship demolition, ship scrapping, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships either as a source of Interchangeable parts, parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about its use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
