Skate-class Submarine
The ''Skate''-class submarines were the United States Navy's first production run of nuclear-powered submarines. They were an evolution of the in everything except their propulsion plants, which were based on the operational prototype . The four ''Skate'' class boats re-introduced stern torpedo tubes. Although among the smallest nuclear-powered attack submarines ever built, the ''Skate'' class served for many years, with the last being decommissioned in 1989. USS ''Skate'' was the first submarine to surface at the North Pole, on 17 March 1959. ''Skate'' and ''Sargo'' were built with the S3W reactor, ''Swordfish'' and ''Seadragon'' also had the S3W reactor in the S4W reactor plant (same machinery in an alternate arrangement). Design The ''Skate'' class were designed under project SCB 121 as economical production nuclear-powered submarines (SSNs), and thus were smaller and more austere than their ground-breaking predecessor , whose high cost had raised concerns. They were design ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ship Characteristics Board
The Ship Characteristics Board was a unit of the United States Navy. The purpose of the Ship Characteristics Board was to coordinate the creation of 'ship characteristics' that are essential to the design of naval combatants and auxiliaries. Coordination was required because the operators and the designers of ships had different interests, perceptions, and concepts: as summarized by the naval historian Norman Friedman, "How to achieve the best possible compromise among competing bureaus has been one of the great dilemmas of 20th-century U.S. naval administration." This list of SCB projects is a useful exposition of the U.S. Navy's shipbuilding priorities in the first half of the Cold War. History The Ship Characteristics Board was founded in 1945 under the Office of the Chief of Naval Operations / OpNav. It was created after the body previously responsible for coordinating ships characteristics, the General Board, had been seen as ineffective in a series of earlier Navy bureau ...

Submarine Classes
A submarine (or sub) is a watercraft capable of independent operation underwater. It differs from a submersible, which has more limited underwater capability. The term is also sometimes used historically or colloquially to refer to remotely operated vehicles and robots, as well as medium-sized or smaller vessels, such as the midget submarine and the wet sub. Submarines are referred to as ''boats'' rather than ''ships'' irrespective of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and they were adopted by several navies. They were first widely used during World War I (1914–1918), and are now used in many navies, large and small. Military uses include attacking enemy surface ships (merchant and military) or other submarines, and for aircraft carrier protection, blockade running, nuclear deterrence, reconnaissance, conventional land attack (for example, using a cruise missile), and covert insertion ...

Electric Boat
An electric boat is a powered watercraft driven by electric motors, which are powered by either on-board battery packs, solar panels or generators. While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine became dominant. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily, especially as more efficient solar cells have become available, for the first time making possible motorboats with a theoretically infinite cruise range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat to complete a round-the-world tour (including a transit of the Panama Canal) using only green technologies is EcoSaili ...

Ship-Submarine Recycling Program
The Ship-Submarine Recycling Program (SRP) is the process that the United States Navy uses to dispose of decommissioned nuclear vessels. SRP takes place only at the Puget Sound Naval Shipyard (PSNS) in Bremerton, Washington, but the preparations can begin elsewhere. Program overview Defueling and decommissioning Before SRP can begin, the vessel's nuclear fuel must be removed, and defueling usually coincides with decommissioning. Until the fuel is removed, the vessel is referred to as "USS ''Name''," but afterward, the "USS" prefix is dropped and it is referred to as "ex-''Name''." Reusable equipment is removed at the same time as the fuel. Spent fuel storage Spent nuclear fuel is shipped by rail to the Naval Reactor Facility in the Idaho National Laboratory (INL), located northwest of Idaho Falls, Idaho, where it is stored in special canisters. Hull salvage At PSNS, the SRP proper begins. The salvage workers cut the submarine into three or four pieces: the aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pearl Harbor
Pearl Harbor is an American lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It was often visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands are now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The surprise attack by the Imperial Japanese Navy on December 7, 1941, led the United States to declare war on the Empire of Japan, making the attack on Pearl Harbor the immediate cause of the United States' entry into World War II. History Pearl Harbor was originally an extensive shallow embayment called ''Wai Momi'' (meaning, “Waters of Pearl”) or ''Puuloa'' (meaning, “long hill”) by the Hawaiians. Puuloa wa ...

Fairwater Plane
Diving planes, also known as hydroplanes, are control surfaces found on a submarine which allow the vessel to pitch its bow and stern up or down to assist in the process of submerging or surfacing the boat, as well as controlling depth when submerged. Bow and stern planes Diving planes are usually fitted in two pairs, the '' bow planes'' at the front of the submarine and the ''stern planes'' at the rear. The stern planes function in much the same way as an aircraft's elevator. As the planes are a long distance fore-and-aft from the hull's centre of buoyancy, they introduce a pitching moment. Ballast tanks within the submarine adjust buoyancy to be neutral, making the boat controllable. The position of the planes controls the pitch of the boat and, with the forward motion of the boat, this controls depth. If not carefully controlled, this could lead to a 'porpoising' motion whereby the planesman continually hunts for a stable combination of depth and pitch. For easier berthi ...

Mark 37 Torpedo
The Mark 37 torpedo is a torpedo with electrical propulsion, developed for the US Navy after World War II. It entered service with the US Navy in the early 1950s, with over 3,300 produced. It was phased out of service key with the US Navy during the 1970s, and the stockpiles were sold to foreign navies. Development Its engineering development began in 1946 by Westinghouse. It was largely based on the concept of the passive homing Mark 27, with added active homing system tested on modified Mark 18s, and a new torpedo body. Between 1955–56, thirty torpedoes were produced for development testing, with large-scale production commenced shortly afterwards. Due to its electric propulsion, the torpedo swam smoothly out of the launch tube, instead of having to be ejected by pressurized air, therefore significantly reducing its acoustic launch signature. To allow for water flow around the torpedo while swimming out, several 1" thick guide studs were attached to the torpedo, which al ...

Annapolis, Maryland
Annapolis ( ) is the capital city of the U.S. state of Maryland and the county seat of, and only incorporated city in, Anne Arundel County. Situated on the Chesapeake Bay at the mouth of the Severn River, south of Baltimore and about east of Washington, D.C., Annapolis forms part of the Baltimore–Washington metropolitan area. The 2020 census recorded its population as 40,812, an increase of 6.3% since 2010. This city served as the seat of the Confederation Congress, formerly the Second Continental Congress, and temporary national capital of the United States in 1783–1784. At that time, General George Washington came before the body convened in the new Maryland State House and resigned his commission as commander of the Continental Army. A month later, the Congress ratified the Treaty of Paris of 1783, ending the American Revolutionary War, with Great Britain recognizing the independence of the United States. The city and state capitol was also the site of the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Naval Institute
The United States Naval Institute (USNI) is a private non-profit military association that offers independent, nonpartisan forums for debate of national security issues. In addition to publishing magazines and books, the Naval Institute holds several annual conferences. The Naval Institute is based in Annapolis, Maryland. Established in 1873, the Naval Institute claimed "almost 50,000 members" in 2020, mostly active and retired personnel of the United States Navy, Marine Corps, and Coast Guard. The organization also has members in over 90 countries. The organization has no official or funding ties to the United States Naval Academy or the U.S. Navy, though it is based on the grounds of the Naval Academy through permission granted by a 1936 Act of Congress. History The U.S. Naval Institute was formed on October 9, 1873 by fifteen naval officers gathered at the U.S. Naval Academy's Department of Physics and Chemistry building in Annapolis to discuss, among other topics, the imp ...

Nuclear-powered Aircraft
A nuclear-powered aircraft is a concept for an aircraft intended to be powered by nuclear energy. The intention was to produce a jet engine that would heat compressed air with heat from fission, instead of heat from burning fuel. During the Cold War, the United States and Soviet Union researched nuclear-powered bomber aircraft, the greater endurance of which could enhance nuclear deterrence, but neither country created any such operational aircraft. One inadequately solved design problem was the need for heavy shielding to protect the crew and those on the ground from radiation; other potential problems included dealing with crashes. Some missile designs included nuclear-powered hypersonic cruise missiles. However, the advent of ICBMs and nuclear submarines in the 1960s greatly diminished the strategic advantage of such aircraft, and respective projects were canceled. U.S. programs NEPA and ANP In May 1946, the United States Army Air Forces started the Nuclear Energy for t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
