USS Requisite (AM-109)
USS ''Requisite'' (AM-109) was an acquired by the United States Navy for the dangerous task of removing mines from minefields laid in the water to prevent ships from passing. ''Requisite'' was laid down 12 November 1941 by the Winslow Marine Railway and Shipbuilding Company, Seattle, Washington; launched 25 July 1942; and commissioned 7 June 1943. World War II Pacific operations Following shakedown off southern California, ''Requisite'' proceeded to San Francisco. Thence on 1 August, she escorted a convoy to Honolulu. Attached to Service Squadron 6, she trained in Hawaiian waters into October. On the 25th, she cleared Pearl Harbor and headed for the New Hebrides to prepare for her first amphibious operation, the invasion of Tarawa Atoll, in the Gilberts. Departing Efate on 13 November, she took up her position as listening vessel at the lagoon entrance off Betio early on the morning of the 20th. While pre-invasion bombardment was in progress, she and swept a channel from t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winslow Marine Railway And Shipbuilding Company
Winslow Marine Railway and Shipbuilding Company was a shipyard in Puget Sound that operated from 1903 until 1959 on Bainbridge Island, Washington, United States. The shipyard was built as an expansion of Hall Bros. Marine Railway & Shipbuilding Company of Port Blakely, Washington, on near the village of Madrone, later renamed Winslow after the dead brother of shipyard owner Henry Hall. It built five-masted schooners whose design allowed cargo to be loaded both fore and aft. Different facilities were included in this yard. It were marine railway, a powerhouse, sawmill, joiner loft, warehouse, shipways. In 1916, Hall sold the Winslow yard to Captain James Griffiths, who renamed it Winslow Marine Railway & Shipbuilding Co. The following year, Griffiths leased the yard to D. W. Hartzel, Inc., which used the facility to install machinery in hulls built at other yards. After World War I, Griffiths retook control of the yard, using it to do repair work for Puget Sound's ferry operators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eniwetok
Enewetak Atoll (; also spelled Eniwetok Atoll or sometimes Eniewetok; mh, Ānewetak, , or , ; known to the Japanese as Brown Atoll or Brown Island; ja, ブラウン環礁) is a large coral atoll of 40 islands in the Pacific Ocean and with its 664 people (as of 2011) forms a legislative district of the Ralik Chain of the Marshall Islands. With a land area total less than , it is no higher than and surrounds a deep central lagoon, in circumference. It is the second-westernmost atoll of the Ralik Chain and is west from Bikini Atoll. It was held by the Japanese from 1914 until its capture by the United States in February 1944, during World War II, then became Naval Base Eniwetok. Nuclear testing by the US totaling the equivalent of over 30 megatons of TNT took place during the Cold War; in 1977–1980, a concrete dome (the Runit Dome) was built on Runit Island to deposit radioactive soil and debris. The Runit Dome is deteriorating and could be breached by a typhoon, though ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atoll
An atoll () is a ring-shaped island, including a coral rim that encircles a lagoon partially or completely. There may be coral islands or cays on the rim. Atolls are located in warm tropical or subtropical oceans and seas where corals can grow. Most of the approximately 440 atolls in the world are in the Pacific Ocean. Two different, well-cited models, the subsidence and antecedent karst models, have been used to explain the development of atolls.Droxler, A.W. and Jorry, S.J., 2021. ''The Origin of Modern Atolls: Challenging Darwin's Deeply Ingrained Theory.'' ''Annual Review of Marine Science'', 13, pp.537-573. According to Charles Darwin's ''subsidence model'', the formation of an atoll is explained by the subsidence of a volcanic island around which a coral fringing reef has formed. Over geologic time, the volcanic island becomes extinct and eroded as it subsides completely beneath the surface of the ocean. As the volcanic island subsides, the coral fringing reef becomes a ...

Kwajalein
Kwajalein Atoll (; Marshallese: ) is part of the Republic of the Marshall Islands (RMI). The southernmost and largest island in the atoll is named Kwajalein Island, which its majority English-speaking residents (about 1,000 mostly U.S. civilian personnel) often use the shortened name, Kwaj . The total land area of the atoll amounts to just over . It lies in the Ralik Chain, southwest of Honolulu, Hawaii. The US Navy has hosted a naval base on Kwajalein Island since World War II. It was the final resting place of the German cruiser '' Prinz Eugen'' after it survived the Operation Crossroads nuclear test in 1946. In the late 1950s, the US Army took over the base as part of their Nike Zeus anti-ballistic missile efforts, and since then the atoll has been widely used for missile tests of all sorts. Today it is part of the Ronald Reagan Ballistic Missile Defense Test Site, with various radars, tracking cameras, missile launchers, and many support systems spread across many islands ...

Antisubmarine
An anti-submarine weapon (ASW) is any one of a number of devices that are intended to act against a submarine and its crew, to destroy (sink) the vessel or reduce its capability as a weapon of war. In its simplest sense, an anti-submarine weapon is usually a projectile, missile or bomb that is optimized to destroy submarines. History Before World War I Prior to about 1890, naval weapons were only used against surface shipping. With the rise of the military submarine after this time, countermeasures were considered for use against them. The first submarine installation of torpedo tubes was in 1885 and the first ship was sunk by a submarine-launched torpedo in 1887. There were only two ways of countering the military submarine initially: ramming them or sinking them with gunfire. However, once they were submerged, they were largely immune until they had to surface again. By the start of the First World War there were nearly 300 submarines in service with another 80 in production ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marshall Islands
The Marshall Islands ( mh, Ṃajeḷ), officially the Republic of the Marshall Islands ( mh, Aolepān Aorōkin Ṃajeḷ),'' () is an independent island country and microstate near the Equator in the Pacific Ocean, slightly west of the International Date Line. Geographically, the country is part of the larger island group of Micronesia. The country's population of 58,413 people (at the 2018 World Bank Census) is spread out over five islands and 29 coral atolls, comprising 1,156 individual islands and islets. The capital and largest city is Majuro. It has the largest portion of its territory composed of water of any sovereign state, at 97.87%. The islands share maritime boundaries with Wake Island to the north, Kiribati to the southeast, Nauru to the south, and Federated States of Micronesia to the west. About 52.3% of Marshall Islanders (27,797 at the 2011 Census) live on Majuro. In 2016, 73.3% of the population were defined as being "urban". The UN also indicates a population d ...

Lagoon
A lagoon is a shallow body of water separated from a larger body of water by a narrow landform, such as reefs, barrier islands, barrier peninsulas, or isthmuses. Lagoons are commonly divided into ''coastal lagoons'' (or ''barrier lagoons'') and ''atoll lagoons''. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around many parts of the world. Definition and terminology Lagoons are shallow, often elongated bodies of water separated from a larger body of water by a shallow or exposed shoal, coral reef, or similar feature. Some authorities include fresh water bodies in the definition of "lagoon", while others explicitly restrict "lagoon" to bodies of water with some degree of salinity. The distinction between "lagoon" and "estuary" also varies between authorities. Richard A. Davis Jr. restrict ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Betio
Betio is the largest township of Kiribati's capital city, South Tarawa, and the country's main port. The settlement is located on a separate islet at the extreme southwest of the atoll. Betio Post Office opened on 5 April 1957 and closed in 1964. In 1967, the Marine Training Centre was created by Hamburg Süd. John Hilary Smith, governor of the Gilbert and Ellice Islands created the Betio Town Council in 1972. Since the 1970s, the islet has become a major centre of economic activity in Kiribati, and a causeway to Bairiki was constructed in the early 1980s, leading to an increase in human contact with the island. Due to changing currents resulting from the construction of the causeway, Bikeman Island, northeast of Betio, has been submerged since the early 1990s. Pacific War The island was the scene of the Battle of Tarawa during World War II. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
