Reserve Fleet
A reserve fleet is a collection of naval vessels of all types that are fully equipped for service but are not currently needed; they are partially or fully Ship decommissioning, decommissioned. A reserve fleet is informally said to be "in mothballs" or "mothballed". In earlier times, especially in British usage, the ships were said to be "laid up in ordinary". A reserve fleet may be colloquially referred to as a "ghost fleet". In the 21st century, ghost fleet may also refer to an active shadow fleet of aged reserve fleet Oil tanker, oil tankers returned to an active service in order to circumvent commodities sanctions. Overview Such ships are held in reserve against a time when it may be necessary to call them back into service. They are usually tied up in backwater areas near naval bases or shipyards in order to speed the reactivation process. They may be modified for storage during such a period, for instance by having rust-prone areas sealed off or wrapped in plastic or, in ...

Reserve Fleet (United Kingdom)
The Reserve Fleet was a Royal Navy formation of decommissioned vessels which could be brought to a state of readiness at time of war. In the early years of the 18th century ships were "laid up in ordinary" at various British naval bases forming a repository for serviceable but decommissioned ships. Sir John Fisher's reforms made these reserve ships more ready for combat, in the lead up to the First World War World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to .... Whilst warships had been laid up in ordinary routinely, the establishment of a Reserve Fleet as a separate, formally established naval formation dated to the change in title and appointment of Vice Admiral Henry Oliver in November 1919. With the breakup of the Grand Fleet in April 1919, Royal Navy forces in home waters ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cargo Ship
A cargo ship or freighter is a merchant ship that carries cargo, goods, and materials from one port to another. Thousands of cargo carriers ply the world's List of seas, seas and Ocean, oceans each year, handling the bulk of international trade. Cargo ships are usually specially designed for the task, often being equipped with crane (machine), cranes and other mechanisms to load and unload, and come in all sizes. Today, they are almost always built of Welding, welded steel, and with some exceptions generally have a life expectancy of 25 to 30 years before being scrapped. Definitions The words ''cargo'' and ''freight'' have become interchangeable in casual usage. Technically, "cargo" refers to the goods carried aboard the ship for hire, while "freight" refers to the act of carrying of such cargo, but the terms have been used interchangeably for centuries. Generally, the modern ocean shipping business is divided into two classes: # Liner business: typically (but not exclusive ...

Aircraft Boneyard
An aircraft boneyard or aircraft graveyard is a storage area for aircraft which are retired from service. Most aircraft at boneyards are either kept for storage continuing to receive some maintenance or parts of the aircraft are removed for reuse or resale and the aircraft are scrapped. Boneyard facilities are generally located in deserts such as those in the southwestern United States, since the dry conditions reduce corrosion and the hard ground does not need to be paved. In some cases, aircraft which were planned to be scrapped or were stored indefinitely without plans of ever returning to service were brought back into service, as the aviation market or the demands of military aviation changed or failed to develop as was anticipated. Some yards are privately owned and operated, others belong to the military including the 309th Aerospace Maintenance and Regeneration Group at Davis-Monthan Air Force Base in Tucson, Arizona. After aircraft are put into boneyards, many are st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Unicorn
Eleven ships of the Royal Navy have borne the name HMS ''Unicorn'', after the mythological creature, the unicorn: * was a 36-gun ship captured from Scotland in 1544 and sold in 1555. * was a 56-gun ship launched in 1634 and sold in 1687. * (or ''Little Unicorn'') was an 18-gun fire ship originally in Dutch service as the ''Eenhoorn''. She was captured in 1665 and expended on 4 June 1666, on the fourth day of the Four Days' Battle. * was a 6-gun purchased in 1666 and sunk as a blockship at Chatham on 11 June 1667, together with five other vessels, in a futile attempt to block the Dutch from advancing up the River Medway. * was a 28-gun sixth rate launched in 1748 and broken up in 1771. * was a 20-gun post ship launched in 1776. The French frigate captured her on 4 October 1780Roche, p. 41. took her into service as ''La Licorne''. recaptured her in April 1781. The Royal Navy took her back into service as ''Unicorn Prize''; she was broken up at Deptford in 1787. * was a 36-g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fallout
Nuclear fallout is residual radioactive material that is created by the reactions producing a nuclear explosion. It is initially present in the radioactive cloud created by the explosion, and "falls out" of the cloud as it is moved by the atmosphere in the minutes, hours, and days after the explosion. The bulk of the radioactivity from nuclear fallout comes from fission products, which are created by the nuclear fission reactions of the nuclear device. Un-fissioned bomb fuel (such as plutonium and uranium), and radioactive isotopes created by neutron activation, make up a smaller amount of the radioactive content of fallout. The amount of fallout and its distribution is dependent on several factors, including the overall yield of the weapon, the fission yield of the weapon, the height of burst of the weapon, and meteorological conditions. Fallout can have serious human health consequences on both short- and long-term time scales, and can cause radioactive contamination far ...

Low-background Steel
Low-background steel, also known as pre-war steel and pre-atomic steel, is any steel produced prior to the Trinity (nuclear test), detonation of the first nuclear bombs in the 1940s and 1950s. Typically obtained from ships (either as part of regular Ship breaking, scrapping or shipwrecks) and other steel artifacts of this era, it is often used for modern particle detectors because more modern steel is contaminated with traces of nuclear fallout. Rationale History of the modern steel industry, From 1856 until the mid 20th century, steel was produced in the Bessemer process, where air was forced into Bessemer converters converting the pig iron into steel. By the mid-20th century, many steelworks had switched to the Basic oxygen steelmaking, BOS process, which uses pure oxygen instead of air. However, as both processes use atmospheric gas, they are susceptible to contamination from airborne particulates. Present-day air carries radionuclides, such as cobalt-60, which are deposite ...

USS Oriskany (CV-34)
USS ''Oriskany'' (CV/CVA-34) ( or ) was one of the few s completed after World War II for the United States Navy. The ship was named for the Battle of Oriskany during the Revolutionary War. The history of ''Oriskany'' differs considerably from that of her sister ships. Originally designed as a "long-hulled" ''Essex''-class ship (considered by some authorities to be a separate class, the ), she was not completed and construction was suspended in 1946 after the end of World War II. She eventually was converted to an updated design called SCB-27 ("27-Charlie") and commissioned in 1950. This updated version became the template for modernization of 14 other ''Essex''-class ships. ''Oriskany'' was the final ''Essex''-class ship completed. She operated primarily in the Pacific into the 1970s, earning two battle stars for service in the Korean War, and ten for service in the Vietnam War. In 1966, one of the worst shipboard fires since World War II broke out on ''Oriskany'' when a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shipbreaking
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 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, 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 ocean ships were broken down, and their aver ...

Artificial Reef
An artificial reef (AR) is a human-created freshwater or marine benthic structure. Typically built in areas with a generally featureless bottom to promote Marine biology#Reefs, marine life, it may be intended to control #Erosion prevention, erosion, protect coastal areas, block ship passage, block the use of trawling nets, support reef restoration, improve aquaculture, or enhance scuba diving and surfing. Early artificial reefs were built by the Persians and the Romans. An opportunity artificial reef is built from objects that were intended for other purposes, such as sinking oil rigs (through the Rigs-to-Reefs program), Sinking ships for wreck diving sites, scuttling ships, or by deploying rubble or construction debris. Shipwrecks may become artificial reefs when preserved on the seafloor. A conventional artificial reef uses materials such as concrete, which can be molded into specialized forms (e.g. The Reef Ball Foundation, reef balls). Green artificial reefs incorporate renewab ...

Museum Ship
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 Historic Naval Ships Association website. Accessed 2008-06-06.) though many are not naval museum ships, from general merchant ships to tugboat, tugs and Lightvessel, lightships. Many, if not most, museum ships are also associated with a maritime museum. Significance Relatively few ships are ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live Fire Exercise
A live fire exercise (LFX) is a military exercise in which live ammunition and ordnance is used, as opposed to blanks or dummies. The term can also be found in non-military usage. Military Militaries usually use live-fire exercises as an opportunity to use real ammunition in a realistically created combat situation. The area in which these tests are conducted will be devoid of people to avoid casualties, and will likely be owned by the government that authorized the test. Most live-fire tests are conducted either against derelict equipment (such as tanks and ships) or against remotely controlled drones. The purpose of this type of exercise is twofold: First, it offers recruits the chance to get accustomed to their weapons so that they will know how to properly operate them. Secondly, this provides soldiers with an opportunity to fire live ammunition without having to worry about an actual enemy returning fire. This allows soldiers to get reacquainted with the feel and time o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
