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 decommissioned. A reserve fleet is informally said to be "in mothballs" or "mothballed"; an equivalent expression in unofficial modern US naval usage is "ghost fleet". In earlier times, especially in British usage, the ships were said to be "laid up in ordinary". 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 the case of sailing warships, the masts removed. While being held in the reserve fleet, ships typically have a minimal crew (known informally as a skeleton crew) to ensure that they stay in somewhat usable co ...

Oil Tankers
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight (DWT) to the mammoth ultra large crude carriers (ULCCs) of . Tankers move approximately of oil every year.UNCTAD 2006, p. 4. Second only to pipelines in terms of efficiency,Huber, 2001: 211. the average cost of transport of crude oil by tanker amounts to only US. Some specialized types of oil tankers have evolved. One of these is the naval replenishment oiler, a tanker which can fuel a m ...

United States Navy Reserve Fleets
The United States Navy maintains a number of its ships as part of a reserve fleet, often called the "Mothball Fleet". While the details of the maintenance activity have changed several times, the basics are constant: keep the ships afloat and sufficiently working as to be reactivated quickly in an emergency. In some cases (for instance, at the outset of the Korean War), many ships were successfully reactivated at a considerable savings in time and money. The usual fate of ships in the reserve fleet, though, is to become too old and obsolete to be of any use, at which point they are sold for scrapping or are scuttled in weapons tests. In rare cases, the general public may intercede for ships from the reserve fleet that are about to be scrapped – usually asking for the Navy to donate them for use as museum ships, memorials, or artificial reefs. Administration In November 1976, the controlling organization was the Inactive Ship Division of the Naval Ship Systems Command. As ...

Suisun Bay Reserve Fleet
The Suisun Bay Reserve Fleet is located on the northwest side of Suisun Bay (the northern portion of the greater San Francisco Bay estuary) in Benicia, California. The fleet is within a regulated navigation area that is about long and wide. It begins just north of the Union Pacific Railroad Bridge and runs northeast, parallel to the shoreline. Water depths range from about at Mean Lower Low Water (MLLW) at the foot of the anchorage, to about MLLW at the shallowest berths towards the northern end of the anchorage. As of 2022, about eight ships remain in the fleet. Purpose The U.S. Maritime Administration (MARAD) maintains the National Defense Reserve Fleet, a fleet of vessels that serves as a reserve of ships for national defense and national emergency purposes. The reserve fleet program began in 1946 at the end of World War II. At its peak in 1950, the program had more than 2,000 ships in lay-up. One of the reserve fleet storage sites is in Suisun Bay, the northern portion ...

Aircraft Boneyard
An aircraft boneyard or aircraft graveyard is a storage area for aircraft that are retired from service. Most aircraft at boneyards are either kept for storage with some maintenance or have their parts removed for reuse or resale and are then 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 that 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 anticipated. Military aircraft The 309th Aerospace Maintenance and Regeneration Group in Tucson, Arizona, the largest facility of its kind, is colloquially known as "The Boneyard". Commercial aircraft Due to the impact of the Covid-19 pandemic on aviation, demand for commercial aircraft sto ...

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 ...

Fallout
Nuclear fallout is the residual radioactive material propelled into the upper atmosphere following a nuclear blast, so called because it "falls out" of the sky after the explosion and the shock wave has passed. It commonly refers to the radioactive dust and ash created when a nuclear weapon explodes. The amount and spread of fallout is a product of the size of the weapon and the altitude at which it is detonated. Fallout may get entrained with the products of a pyrocumulus cloud and fall as black rain (rain darkened by soot and other particulates, which fell within 30–40 minutes of the atomic bombings of Hiroshima and Nagasaki). This radioactive dust, usually consisting of fission products mixed with bystanding atoms that are neutron-activated by exposure, is a form of radioactive contamination. Types of fallout Fallout comes in two varieties. The first is a small amount of carcinogenic material with a long half-life. The second, depending on the height of detonation, is a ...

Low-background Steel
Low-background steel, also known as pre-war steel, is any steel produced prior to the detonation of the first nuclear bombs in the 1940s and 1950s. Typically sourced from 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. Since the cessation of atmospheric nuclear testing, background radiation has decreased to very near natural levels, making special low-background steel no longer necessary for most radiation-sensitive applications, as brand-new steel now has a low enough radioactive signature that it can generally be used in such applications. However, some demand remains for the most radiation-sensitive applications, such as Geiger counters and sensing equipment aboard spacecraft, and World War II-era shipwrecks near in the Java Sea and western South China Sea are often illegally scavenged for low-background steel. Radionuclide contamination From 1856 until t ...

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 ...

Shipbreaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either 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 the 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 average age was 26 ...

Artificial Reef
An artificial reef is a human-created underwater structure, typically built to promote marine life in areas with a generally featureless bottom, to control erosion, block ship passage, block the use of trawling nets, or improve surfing. Many reefs are built using objects that were built for other purposes, such as by sinking oil rigs (through the Rigs-to-Reefs program), scuttling ships, or by deploying rubble or construction debris. Other artificial reefs are purpose-built (e.g. the reef balls) from PVC or concrete. Shipwrecks may become artificial reefs when preserved on the seafloor. Regardless of construction method, artificial reefs generally provide hard surfaces where algae and invertebrates such as barnacles, corals, and oysters attach; the accumulation of attached marine life in turn provides intricate structures and food for assemblages of fish. History The construction of artificial reefs began in ancient times. Persians blocked the mouth of the Tigris River to ...

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
