Nuclear-powered Submarines
A nuclear submarine is a submarine powered by a nuclear reactor, but not necessarily nuclear-armed. Nuclear submarines have considerable performance advantages over "conventional" (typically diesel-electric) submarines. Nuclear propulsion, being completely independent of air, frees the submarine from the need to surface frequently, as is necessary for conventional submarines. The large amount of power generated by a nuclear reactor allows nuclear submarines to operate at high speed for long periods, and the long interval between refuelings grants a range virtually unlimited, making the only limits on voyage times being imposed by such factors as the need to restock food or other consumables. The limited energy stored in electric batteries means that even the most advanced conventional submarine can only remain submerged for a few days at slow speed, and only a few hours at top speed, though recent advances in air-independent propulsion have somewhat ameliorated this disad ...

Bureau Of Ships
The United States Navy's Bureau of Ships (BuShips) was established by Congress on 20 June 1940, by a law which consolidated the functions of the Bureau of Construction and Repair (BuC&R) and the Bureau of Engineering (BuEng). The new bureau was to be headed by a chief and deputy-chief, one selected from the Engineering Corps (Marine Engineer) and the other from the Construction Corps (Naval Architect). The chief of the former Bureau of Engineering, Rear Admiral Samuel M. "Mike" Robinson, was named BuShips' first chief, while the former chief of the Bureau of Construction & Repair, Rear Admiral Alexander H. Van Keuren, was named as BuShips' first Deputy-Chief. The bureau's responsibilities included supervising the design, construction, conversion, procurement, maintenance, and repair of ships and other craft for the Navy; managing shipyards, repair facilities, laboratories, and shore stations; developing specifications for fuels and lubricants; and conducting salvage operations.

Groton, Connecticut
Groton is a town in New London County, Connecticut located on the Thames River. It is the home of General Dynamics Electric Boat, which is the major contractor for submarine work for the United States Navy. The Naval Submarine Base New London is located in Groton, and the pharmaceutical company Pfizer is also a major employer. Avery Point in Groton is home to a regional campus of the University of Connecticut. The population was 38,411 at the 2020 census. History Groton was established in 1705 when it separated from New London, Connecticut. The town was named after Groton, Suffolk in England. A hundred years before it was established, the Niantic people settled in the area between the Thames River and Pawcatuck River, but they eventually settled in Westerly, Rhode Island. The newcomers to the land were the Pequots, a branch of the Mohawk people who moved eastward into the Connecticut River Valley. The summer of 1614 was the first time that the Pequots encountered white settl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing corre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Mamie Eisenhower
Mary Geneva "Mamie" Eisenhower (; November 14, 1896 – November 1, 1979) was the first lady of the United States from 1953 to 1961 as the wife of President Dwight D. Eisenhower. Born in Boone, Iowa, she was raised in a wealthy household in Colorado. She married Dwight D. Eisenhower, then a lieutenant in the Army, in 1916. She kept house and served as hostess for military officers as they moved between various postings in the United States, Panama, the Philippines, and France. Their relationship was complicated by his regular absences on duty and by the death of their firstborn son at the age of three. She became a prominent figure during World War II as the wife of General Eisenhower. As first lady, Eisenhower was given near total control over the expenses and scheduling of the White House. She closely managed the staff, and her frugality was apparent in White House budgeting throughout her tenure. She entertained many foreign heads of state in her role as hostess. She s ...

General Dynamics Electric Boat
General Dynamics Electric Boat (GDEB) is a subsidiary of General Dynamics Corporation. It has been the primary builder of submarines for the United States Navy for more than 100 years. The company's main facilities are a shipyard in Groton, Connecticut, a hull-fabrication and outfitting facility in Quonset Point, Rhode Island, and a design and engineering facility in New London, Connecticut. History The company was founded in 1899 by Isaac Rice as the Electric Boat Company to build John Philip Holland's submersible ship designs, which were developed at Lewis Nixon's Crescent Shipyard in Elizabeth, New Jersey. ''Holland VI'' was the first submarine that this shipyard built, which became when it was commissioned into the United States Navy on April 11, 1900—the first submarine to be officially commissioned. The success of ''Holland VI'' created a demand for follow-up models (A class or ) that began with the prototype submersible ''Fulton'' built at Electric Boat. Some foreig ...

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] |
Twenty Thousand Leagues Under The Sea
''Twenty Thousand Leagues Under the Seas'' (french: Vingt mille lieues sous les mers) is a classic science fiction adventure novel by French writer Jules Verne. The novel was originally serialized from March 1869 through June 1870 in Pierre-Jules Hetzel's fortnightly periodical, the . A deluxe octavo edition, published by Hetzel in November 1871, included 111 illustrations by Alphonse de Neuville and Édouard Riou. The book was widely acclaimed on its release and remains so; it is regarded as one of the premier adventure novels and one of Verne's greatest works, along with '' Around the World in Eighty Days'' and ''Journey to the Center of the Earth''. Its depiction of Captain Nemo's underwater ship, the ''Nautilus'', is regarded as ahead of its time, since it accurately describes many features of today's submarines, which in the 1860s were comparatively primitive vessels. A model of the French submarine ''Plongeur'' (launched in 1863) figured at the 1867 Exposition Universe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jules Verne
Jules Gabriel Verne (;''Longman Pronunciation Dictionary''. ; 8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright.

Captain Nemo
Captain Nemo (; later identified as an Indian, Prince Dakkar) is a fictional character created by the French novelist Jules Verne (1828–1905). Nemo appears in two of Verne's science-fiction classics, ''Twenty Thousand Leagues Under the Seas'' (1870) and ''The Mysterious Island'' (1875). He also makes a brief appearance in a play written by Verne with the collaboration of Adolphe d'Ennery, '' Journey Through the Impossible'' (1882). Nemo is a mysterious figure. Though originally of unknown nationality, he is later described as the son of an Indian raja. A scientific visionary, he roams the depths of the seas in his submarine, the ''Nautilus'', which was assembled from parts manufactured in several different countries, then shipped to a cover address. The captain is consumed by a hunger for vengeance and hatred of imperialism; the British Empire is ultimately revealed as his main antagonist. Nemo has appeared in various film adaptations of Verne's novels, where he has been portra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
