SINKEX
A target ship is a vessel — typically an obsolete or captured warship — used as a seaborne target for naval gunnery practice or for weapons testing. Targets may be used with the intention of testing effectiveness of specific types of ammunition; or the target ship may be used for an extended period of routine target practice with specialized non-explosive ammunition. The potential consequences of a drifting wreck require careful preparation of the target ship to prevent pollution, or a floating or submerged collision risk for maritime navigation. Rationale Sinking redundant warships is an effective way of testing new weapons and warships in as realistic a manner as possible. Preparation In order to meet environmental, health, and safety standards, ships now have to be thoroughly cleaned so that all dangerous material and potential contaminants (such as asbestos, refrigerants etc.) are removed. In the event of the vessel becoming an artificial reef, escape exits also have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurd Deep
Hurd's Deep (or Hurd Deep) is an underwater valley in the English Channel, northwest of the Channel Islands. Its maximum depth is about 180 m (590 ft; 98 fathoms), making it the deepest point in the English Channel. Toponym The feature was named after the British Royal Naval Captain Thomas Hurd (1747–1823), who was the second Hydrographer of the Navy. It was chosen by the RN marine cartographer Admiral Martin White. Geology Hurd's deep began to form in the Pleistocene of the late Quaternary period (in the last 750,000 - 500,000 years). Successive melting periods after ice ages caused water to gouge out a deep water trench through a river valley system that now forms the seabed in the eastern part end of the English Channel. At some point a catastrophic flood from the southern North Sea basin created Hurd's Deep. It's believed that the collapse of a chalk ridge that once dammed the Strait of Dover let flood waters from a huge proglacial lake flow through the former ...

Heavy Cruiser
A heavy cruiser was a type of cruiser, a naval warship designed for long range and high speed, armed generally with naval guns of roughly 203 mm (8 inches) in calibre, whose design parameters were dictated by the Washington Naval Treaty of 1922 and the London Naval Treaty of 1930. Heavy cruisers were generally larger, more heavily armed and more heavily armoured than light cruisers while being smaller, faster, and more lightly armed and armoured than battlecruisers and battleships. Heavy cruisers were not considered capital ships, unlike battlecruisers, battleships, and fleet carriers. Heavy cruisers were assigned a variety of roles ranging from commerce raiding to serving as 'cruiser-killers,' i.e. hunting and destroying similarly sized ships. The heavy cruiser is part of a lineage of ship design from 1915 through the early 1950s, although the term "heavy cruiser" only came into formal use in 1930. The heavy cruiser's immediate precursors were the light cruiser design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axis Powers
The Axis powers, originally called the Rome–Berlin Axis and also Rome–Berlin–Tokyo Axis, was the military coalition which initiated World War II and fought against the Allies of World War II, Allies. Its principal members were Nazi Germany, Fascist Italy, Kingdom of Italy and the Empire of Japan. The Axis were united in their far-right positions and general opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion. The Axis grew out of successive diplomatic efforts by Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the Italo-German protocol of 23 October 1936, protocol signed by Germany and Italy in October 1936, after which Italian leader Benito Mussolini declared that all other European countries would thereafter rotate on the Rome–Berlin axis, thus creating the term "Axis". The following November saw the ratification of the Anti-Comintern Pact, an anti-communis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bikini Atoll
Bikini Atoll ( or ; Marshallese language, Marshallese: , , ), known as Eschscholtz Atoll between the 19th century and 1946, is a coral reef in the Marshall Islands consisting of 23 islands surrounding a central lagoon. The atoll is at the northern end of the Ralik Chain, approximately northwest of the capital Majuro. After the Second World War, the atoll was chosen by the United States as a nuclear weapon testing site. It would be the site of the fourth nuclear bomb detonation and would go on to be the site of many more tests. The people that lived on Bikini—all 167 of the atoll's inhabitants—agreed to relocate after being informed of the plan to test then-new nuclear weapons, of great importance to humankind, though it is sometimes considered a forced relocation. In 1946 they moved to Rongerik, a small island east of Bikini Atoll, but it turned out to have inadequate resources to support the population. The islanders began experiencing starvation by early 1948, and they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Crossroads
Operation Crossroads was a pair of nuclear weapon tests conducted by the United States at Bikini Atoll in mid-1946. They were the first nuclear weapon tests since Trinity on July 16, 1945, and the first detonations of nuclear devices since the atomic bombing of Nagasaki on August 9, 1945. The purpose of the tests was to investigate the effect of nuclear weapons on warships. The Crossroads tests were the first of many nuclear tests held in the Marshall Islands and the first to be publicly announced beforehand and observed by an invited audience, including a large press corps. They were conducted by Joint Army/Navy Task Force One, headed by Vice Admiral William H. P. Blandy rather than by the Manhattan Project, which had developed nuclear weapons during World War II. A fleet of 95 target ships was assembled in Bikini Lagoon and hit with two detonations of Fat Man plutonium implosion-type nuclear weapons of the kind dropped on Nagasaki in 1945, each with a yield of . ...

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.

Liberty Ship
Liberty ships were a ship class, class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Although British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output. The class was developed to meet British orders for transports to replace ships that had been lost. Eighteen American shipyards built 2,710 Liberty ships between 1941 and 1945 (an average of three ships every two days), easily the largest number of ships ever produced to a single design. The Liberty ship was effectively superseded by the Victory ship, a somewhat larger, materially faster, more modern-powered vessel of generally similar design. Over 500 were built between 1943 and 1945. Liberty ship production mirrored (albeit on a much larger scale) the manufacture of "Hog Islander" and similar standardized ship types duri ...

USS Utah (BB-31)
USS ''Utah'' (BB-31/AG-16) was the second of two dreadnought battleships. The first ship of the United States Navy named after the state of Utah, she had one sister ship, . ''Utah'' was built by the New York Shipbuilding Corporation, laid down in March 1909 and launched in December of that year. She was completed in August 1911, and was armed with a main battery of ten guns in five twin gun turrets. ''Utah'' and ''Florida'' were the first ships to arrive during the United States occupation of Veracruz in 1914 during the Mexican Revolution. The two battleships sent ashore a landing party that began the occupation of the city. After the American entrance into World War I, ''Utah'' was stationed at Berehaven in Bantry Bay, Ireland, where she protected convoys from potential German surface raiders. Throughout the 1920s, the ship conducted numerous training cruises and fleet maneuvers, and carried dignitaries on tours of South America twice, in 1924 and 1928. In 1931, ''Utah'' ...

John Hays Hammond Jr
John Hays Hammond Jr. (April 13, 1888 – February 12, 1965) was an American inventor known as "The Father of Radio Control". Hammond's pioneering developments in electronic remote control are the foundation for all modern radio remote control devices, including modern missile guidance systems, unmanned aerial vehicles (UAVs), and the unmanned combat aerial vehicle (UCAVs). Of Hammond's many individual inventions, the inventions which have seen the most significant application are the variable pitch or controlled pitch propellers and single dial radio tuning. He was the son of mining engineer John Hays Hammond, Sr. Biography Born in San Francisco, California, he and his family moved to South Africa and the Transvaal in 1893. His father was active as a mining engineer for Cecil Rhodes' mines in South Africa. In 1898, the family moved to England, where young Hammond fell in love with castles and life in earlier times. The family returned to the United States at the turn of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
