Mitscher-class Destroyer
The ''Mitscher''-class destroyer was an experimental destroyer class of four ships that were built for the United States Navy shortly after World War II. Considerably larger than all previous destroyers, but smaller than their immediate predecessor, the experimental ''Norfolk'', they would have been the first post-war destroyer class had they not been reclassified during construction as destroyer leaders (DL). Commissioned in 1953–1954, two of the class served until 1969, and were scrapped in the 1970s. The other two were converted into guided missile destroyers (DDG), served until 1978, and were sold for scrap by 1980. Description All four ''Mitscher''-class ships were designed under project SCB 5 and ordered 3 August 1948. They were named for admirals of the Second World War. Each ship displaced 3,331 tons light, 3,642 tons standard and 4,855 tons under full load with a length of , a beam and a draft. Beyond that, each ship had a different loadout of prop ...

Bath Iron Works
Bath Iron Works (BIW) is a major United States shipyard located on the Kennebec River in Bath, Maine, founded in 1884 as Bath Iron Works, Limited. Since 1995, Bath Iron Works has been a subsidiary of General Dynamics. It is the fifth-largest defense contractor in the world as of 2008. BIW has built private, commercial, and military vessels, most of which have been ordered by the United States Navy. History Bath Iron Works was incorporated in 1884 by General Thomas W. Hyde, a native of Bath who served in the American Civil War. After the war, he bought a shop that made windlasses and other iron hardware for the wooden ships built in Bath's many shipyards. He expanded the business by improving its practices, entering new markets, and acquiring other local businesses. By 1882, Hyde Windlass was eyeing the new and growing business of iron shipbuilding, and it incorporated as Bath Iron Works in 1884. On February 28, 1890, BIW won its first contract for complete vessels: two iron gu ... [...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 ...

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 1786 An ... [...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 impli ...

List Of United States Navy Destroyer Leaders
In the 1930s, the United States Navy built two classes of flotilla leaders, the ''Porter'' class, and the ''Somers'' class. Due to the regulations of the London Naval Treaty, these 13 ships had a displacement of 1,850 tons, compared to the 1,500 tons of a "standard" destroyer. When the treaty ended with the outbreak of World War II in Europe in 1939, the much larger ''Fletcher'' class was constructed, making the differentiation irrelevant. Following the war, destroyer leader (DL) was a hull classification symbol used by the U.S. Navy from the 1950s until 1975. These ships were more commonly called frigates, although they were much larger than frigates of other navies. They were intended to be larger and more capable than destroyers and to lead a destroyer task force. During the 1975 USN ship reclassification these ships were reclassified as guided missile destroyers (DDG) or guided missile cruisers (CG). The last one of these ships was decommissioned in 1999. A total of 41 ship ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

USS Mitscher (DL-2)
USS ''Mitscher'' (DL-2/DDG-35), named for Admiral Marc "Pete" Mitscher USN (1887–1947), was the lead ship of her class of destroyer leaders of the United States Navy. Commissioned in 1953, she was later converted to a guided missile destroyer, and served until 1978. She was sold for scrap in 1980. Construction and commissioning Originally designated DD-927, she was laid down by the Bath Iron Works Corporation at Bath, Maine on 3 October 1949, reclassified as a destroyer leader and designated DL-2 on 2 February 1951, launched on 26 January 1952 by Mrs. Marc A. Mitscher, widow of Admiral Mitscher and commissioned on 15 May 1953. Service ''Mitscher'' was initially homeported in Newport, R.I., and became the operational flagship for Commander Destroyer Flotilla Two. After initial shakedown exercises off Cuba, ''Mitscher'' returned to Boston for further modification, followed by another shakedown cruise to Guantanamo Bay, ending 31 August 1954. Homeported thereafter at Newport ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cost-effectiveness Analysis
Cost-effectiveness analysis (CEA) is a form of economic analysis that compares the relative costs and outcomes (effects) of different courses of action. Cost-effectiveness analysis is distinct from cost–benefit analysis, which assigns a monetary value to the measure of effect. Cost-effectiveness analysis is often used in the field of health services, where it may be inappropriate to monetize health effect. Typically the CEA is expressed in terms of a ratio where the denominator is a gain in health from a measure (years of life, premature births averted, sight-years gained) and the numerator is the cost associated with the health gain. The most commonly used outcome measure is quality-adjusted life years (QALY). Cost–utility analysis is similar to cost-effectiveness analysis. Cost-effectiveness analyses are often visualized on a plane consisting of four quadrants, the cost represented on one axis and the effectiveness on the other axis. Cost-effectiveness analysis focuses on m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CL-154-class Cruiser
The CL-154 class of gun light cruisers was a United States Navy project from the last two years of World War II, with antecedents reaching back to 1938 and earlier. The CL-154 class was contemporary to the gun light cruisers and the gun s: like them the CL-154 design incorporated the lessons learned of World War II combat. The Navy allocated six hull numbers (CL-154 through CL-159) to the CL-154 class for the planned construction, but unlike the ''Worcester'' and ''Des Moines'' classes the CL-154 class would be cancelled with no units named or constructed. Had these ships been built, they would have been given the hull classification ''CLAA'' (anti-aircraft light cruiser) on 18 March 1949. Overview The CL-154 class was the final attempt to build a "super-" by replacing the ''Atlanta''s 5-inch/38-caliber gun with the new 5-inch/54-caliber Mark 16 gun. The new gun had a higher rate of fire and a longer range than the 38-caliber gun, and fired a heavier and more destructive pro ...

Draft (ship)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...
