Naval Submarine Base New London
Naval Submarine Base New London is the primary United States Navy East Coast submarine base, also known as the "Home of the Submarine Force." It is located in Groton, Connecticut directly across the Thames River from its namesake city of New London. History In 1868, the State of Connecticut gave the Navy of land along the Thames River in Groton to build a Naval Station. Due to a lack of federal funding, it was not until 1872 that two brick buildings and a T-shaped pier were constructed and officially declared a Navy Yard. In 1898, Congress approved a coaling station to be built at the Yard for refueling small naval ships traveling through the waters of New England. The Navy Yard was first used for laying up inactive ships. The Congressional appropriations were small and the Navy had little need for the yard, which was closed from 1898 to 1900 and its personnel reassigned. By 1912, oil replaced coal in warships and again the Yard was scheduled for closure and the land relinqui ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

Ships Built In Sparrows Point, Maryland
A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. After the 15th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a ship-rigged sailing ship with three or more masts, each of which is square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion dead weight tons. Of these 28% were oil tankers, 43% were bulk carriers, and 13% were con ...

Naval Sea Systems Command
The Naval Sea Systems Command (NAVSEA) is the largest of the United States Navy's five "systems commands," or materiel (not to be confused with "material") organizations. From a physical perspective, NAVSEA has four shipyards for shipbuilding, conversion, and repair, ten "warfare centers" (two undersea and eight surface), the NAVSEA headquarters, located at the Washington Navy Yard, in Washington D.C., and other locations in 15 states and 3 overseas continents. NAVSEA's primary objective is to engineer, build, buy, and maintain the U.S. Navy's fleet of ships and its combat systems. NAVSEA's budget of almost $30 billion accounts for nearly one quarter of the Navy's entire budget, with more than 80,200 personnel and 150 acquisition programs under its oversight. History The origin of NAVSEA dates to 1794, when Commodore John Barry was charged to oversee the construction of a 44-gun frigate and ensure that all business "harmonized and conformed" to the public's interest.

SSN (hull Classification Symbol)
An SSN is a nuclear-powered general-purpose attack submarine. ''SSN'' is the US Navy hull classification symbol for such vessels; the ''SS'' denotes a submarine and the ''N'' denotes nuclear power. The designation SSN is used for interoperability throughout NATO under STANAG 1166, though navies use other terms. History The first nuclear-powered attack submarine was the US Navy's , operational from 1954. This was followed by the four submarines of the entering service in 1957. The Royal Navy's first nuclear fleet submarine was which by using an American reactor entered service in 1963. The first all-British nuclear submarines were the two s. The USN submarine fleet has been all-nuclear powered for over two decades. The bulk of the USN's SSN fleet has been the ''Los Angeles''-class attack submarine. Designed during the Cold War the ''Los Angeles''-class boats ''raison d'etre'' was to protect USN carrier battle groups and to hunt Soviet Navy SSBNs before they could launch a fir ...

Virginia-class Submarine
The ''Virginia'' class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy. Designed by General Dynamics Electric Boat (EB) and Huntington Ingalls Industries, the ''Virginia'' class is the United States Navy's latest submarine model, which incorporates the latest in stealth, intelligence gathering, and weapons systems technology. ''Virginia''-class submarines are designed for a broad spectrum of open-ocean and littoral missions, including anti-submarine warfare and intelligence gathering operations. They are scheduled to replace older s, many of which have already been decommissioned. ''Virginia''-class submarines will be acquired through 2043, and are expected to remain in service until at least 2060, with later submarines expected to remain into the 2070s. History The class was developed under the codename Centurion, later renamed New SSN (NSSN). The "Centurion Study" was initiated in ...

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 ...
