Fore River Shipyard
Fore River Shipyard was a shipyard owned by General Dynamics Corporation located on Weymouth Fore River in Braintree and Quincy, Massachusetts. It began operations in 1883 in Braintree, and moved to its final location on Quincy Point in 1901. In 1913, it was purchased by Bethlehem Steel, and later transferred to Bethlehem Shipbuilding Corporation. It was sold to General Dynamics in 1963, and closed in 1986. During its operation, yardworkers constructed hundreds of ships, for both military and civilian clients. Most of the ships at the yard were built for the United States Navy, with its first government contract for the destroyer . The yard also built early submarines for Electric Boat, including and . Fore River also constructed the battleship , and the cruisers and as well as the Navy's first carrier and its successor . Fore River produced multiple foreign ships for various navies around the world including five Type 1 submarines for the Imperial Japanese Navy, ten su ...

Standard Displacement
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" (or "load lines"). A merc ...

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Gibbs & Cox
Gibbs & Cox is an American naval architecture firm that specializes in designing surface warships. Founded in 1922 in New York City, Gibbs & Cox is now headquartered in Arlington, Virginia. The firm has offices in New York City; Washington, D.C.; Newport News, Virginia; Philadelphia, Pennsylvania; and New Orleans, LA. In 2003, more than 150 warships built to the firm's designs, including 60 percent of the U.S. Navy's surface combatant fleet, were on active duty in nearly 20 navies. History The firm was founded as "Gibbs Brothers" by self-taught naval architect William Francis Gibbs and his brother Frederic H. Gibbs. The name was changed when architect Daniel H. Cox of Cox & Stevens joined the firm in 1929. In 1931, Gibbs & Cox designed the MV ''Savarona'', a large luxury yacht. According to company officials, more than 70 percent of U.S. tonnage launched during World War II was built to Gibbs & Cox designs. Ship types included destroyers, LST landing craft, minesweepers, tan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Farragut-class Destroyer (1934)
The ''Farragut''-class destroyers were a class of eight 1,365-ton destroyers in the United States Navy and the first US destroyers of post-World War I design. Their construction, along with the , was authorized by Congress on 29 April 1916, but funding was delayed considerably. Limited to 1,500 tons standard displacement by the provisions of the London Naval Treaty of 1930, the ships were laid down beginning in 1932 and were completed by 1935. After 12 years since the last of the previous class of American destroyers (the ) was commissioned, the ''Farragut''s were commissioned in 1934 and 1935. These ships were slightly larger than their predecessors, faster, and they had only two stacks, versus the four stacks common to all the earlier classes. The class was the first of six classes of 1,500-ton destroyers built in the 1930s to modernize the United States Navy, and all eight ''Farragut''s saw extensive front-line service during World War II. None were lost in battle, although on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bethlehem Shipbuilding Company
Bethlehem Steel Corporation Shipbuilding Division was created in 1905 when the Bethlehem Steel Corporation of Bethlehem, Pennsylvania, acquired the San Francisco shipyard Union Iron Works. In 1917 it was incorporated as Bethlehem Shipbuilding Corporation, Limited. The division's headquarters were moved to Quincy, Massachusetts, after acquiring the Fore River Shipyard in 1913. In 1940, Bethlehem Shipbuilding was the largest of the "Big Three" U.S. shipbuilders that could build any ship, followed by Newport News Shipbuilding & Drydock and New York Shipbuilding Corporation (New York Ship). It had four yards: Fore River, Sparrows Point, San Francisco, and Staten Island. Bethlehem expanded during World War II as a result of the Emergency Shipbuilding program administered under the United States Maritime Commission. In 1964, the now-corporate headquarters moved to Sparrows Point, Maryland, southeast of Baltimore, Maryland, whose shipyard had been acquired in 1916. The Quincy / F ...

Presidential Unit Citation (United States)
The Presidential Unit Citation (PUC), originally called the Distinguished Unit Citation, is awarded to units of the uniformed services of the United States, and those of allied countries, for extraordinary heroism in action against an armed enemy on or after 7 December 1941 (the date of the Attack on Pearl Harbor and the start of American involvement in World War II). The unit must display such gallantry, determination, and '' esprit de corps'' in accomplishing its mission under extremely difficult and hazardous conditions so as to set it apart from and above other units participating in the same campaign. Since its inception by President Franklin D. Roosevelt with the signing of Executive Order 9075 on 26 February 1942, retroactive to 7 December 1941, to 2008, the Presidential Unit Citation has been awarded in conflicts such as World War II, the Korean War, the Vietnam War, Iraq War, and the War in Afghanistan. The collective degree of valor (combat heroism) against an armed e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of The Philippine Sea
The Battle of the Philippine Sea (June 19–20, 1944) was a major naval battle of World War II that eliminated the Imperial Japanese Navy's ability to conduct large-scale carrier actions. It took place during the United States' amphibious invasion of the Mariana Islands during the Pacific War. The battle was the last of five major "carrier-versus-carrier" engagements between American and Japanese naval forces, and pitted elements of the United States Navy's Fifth Fleet against ships and aircraft of the Imperial Japanese Navy's Mobile Fleet and nearby island garrisons. This was the largest carrier-to-carrier battle in history, involving 24 aircraft carriers, deploying roughly 1,350 carrier-based aircraft. The aerial part of the battle was nicknamed the Great Marianas Turkey Shoot by American aviators for the severely disproportional loss ratio inflicted upon Japanese aircraft by American pilots and anti-aircraft gunners. During a debriefing after the first two air battles, a pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
