United States Navy Bureau System
The "bureau system" of the United States Navy was the United States Department of the Navy, Department of the Navy's material-support organization from 1842 through 1966. The bureau chiefs were largely autonomous, reporting directly to the Secretary of the Navy and managing their respective organizations without the influence of other bureaus. In 1966, the bureaus were gradually replaced by unified commands (generally known as "United States Navy systems commands, systems commands" or SYSCOMs) reporting to the Chief of Naval Operations. Before the bureaus For the first several decades of the United States Navy Department, Navy Department's existence, all procurement and material matters were handled directly by the Office of the Secretary of the Navy. As the navy expanded during the War of 1812, it became clear that this system was not sufficient for the service's needs. On February 7, 1815, Congress established a three-member Board of Navy Commissioners, Board of Naval Commission ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Department Of The Navy
The United States Department of the Navy (DoN) is one of the three military departments within the Department of Defense of the United States of America. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN);Bernard C. Steiner and James McHenry, The life and correspondence of James McHenry' (Cleveland: Burrows Brothers Co., 1907). since 1834, it has exercised jurisdiction over the U.S. Marine Corps (USMC) and, during wartime, the U.S. Coast Guard (USCG), though each remains an independent service branch. It is led by the Secretary of the Navy (SECNAV), a statutory civilian officer. The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military service ...

Bureau Of Supplies And Accounts
The Bureau of Supplies and Accounts (BuSandA) was the United States Navy's supply organization between 1892 and 1966. Established in 1842 as the Bureau of Provisions and Clothing, the bureau was responsible for the procurement, receipt, storage, shipment, and issuance of food, fuel, clothing, general stores, and other materials. BuSandA also maintained and operated naval supply depots and similar units, and supervised activities of the Navy's Supply Corps officers. Duties also included the procurement, allocation, and disbursement of funds, and the holding of money and property accounts. BuSandA was disestablished in 1966, as part of the Navy's general restructuring of its procurement system, and replaced with the Naval Supply Systems Command (NAVSUP). History The bureau was established by Act of Congress on August 31, 1842 (5 Stat. 579) as the Bureau of Provisions and Clothing, one of the Navy Department's five original procurement bureaus replacing the Board of Navy Commissio ...

16"/50 Caliber Mark 7 Gun
The 16"/50 caliber Mark 7 – United States Naval Gun is the main armament of the ''Iowa''-class battleships and was the planned main armament of the cancelled . Description Due to a lack of communication during design, the Bureau of Ordnance assumed the ''Iowa'' class would use the /50 Mark 2 guns constructed for the 1920 ''South Dakota''-class battleships. However, the Bureau of Construction and Repair assumed that the ships would carry a compact 16-in/50 turret and designed the ships with barbettes too small to accommodate the 16-in/50 Mark 2 three-gun turret that the Bureau of Ordnance was actually working on. The new lightweight 16-in/50 Mark 7 was designed to resolve this conflict. These guns were 50 calibers long—or 50 times their bore diameter, which makes the barrels long, from chamber to muzzle. Each gun weighed about without the breech, and with the breech. They fired projectiles weighing from at different muzzle velocities, depending on the shell. Whe ...

Lexington-class Battlecruiser
The ''Lexington''-class battlecruisers were officially the only ship class, class of battlecruiser to ever be ordered by the United States Navy. While these six vessels were requested in 1911 as a reaction to the building by Japan of the , the potential use for them in the U.S. Navy came from a series of studies by the Naval War College which stretched over several years and predated the existence of the first battlecruiser, (a series of proposed battlecruiser designs was in fact submitted to the General Board of the United States Navy, General Board in 1909 but was not approved for construction). The fact they were not approved by Congress at the time of their initial request was due to political, not military considerations. The ''Lexington''s were included as part of the Naval Act of 1916. Like the battleships also included in the 1916 Act, their construction was repeatedly postponed in favor of escort ships and anti-submarine vessels. During these delays, the class was rede ...

South Dakota-class Battleship (1920)
The first ''South Dakota'' class was a group of six battleships that were laid down in 1920 for the U.S. Navy, but were never completed; designed to achieve , they represented an attempt to catch up with the increasing fleet speeds of its main rivals, the British Royal Navy and Imperial Japanese Navy. The ''South Dakota''s were authorized in 1917, but work was postponed so that the U.S. Navy could incorporate information gained from the Battle of Jutland, fought in mid-1916, in their design. Work was further postponed to give destroyers and other small fighting vessels priority as they were needed urgently to fight German U-boats in the North Atlantic. Construction started only in 1920. As the Washington Naval Treaty of 1922 both restricted the total battleship tonnage allowed the U.S. Navy, and limited individual ship size to , construction was halted in early 1922. The unfinished hulls were scrapped the following year, the guns were transferred to the U.S. Army and their boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
16-inch/50-caliber Mark 2 Gun
The 16"/50 caliber Mark 2 gun and the near-identical Mark 3 were guns originally designed and built for the United States Navy as the main armament for the ''South Dakota''-class battleships and s. The successors to the 16"/45 caliber gun Mark I gun, they were at the time among the heaviest guns built for use as naval artillery. As part of the Washington Naval Treaty of 1922, both of these ship classes were cancelled part way through construction, rendering surplus about 70 examples of the 16-inch/50 which had already been built. Twenty were released to the US Army, between 1922–1924, for use by the Coast Artillery Corps, the rest were kept in storage for future naval use. Only ten of the twenty available guns were deployed (in five two-gun batteries) prior to 1940.Berhow, p. 61 When the design of the began in 1938, it was initially assumed these ships would use the surplus guns. However, due to a miscommunication between the two Navy departments involved in the design, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iowa-class Battleship
The ''Iowa'' class was a class of six fast battleships ordered by the United States Navy in 1939 and 1940. They were initially intended to intercept fast capital ships such as the Japanese while also being capable of serving in a traditional battle line alongside slower battleships and act as its "fast wing". The ''Iowa'' class was designed to meet the Second London Naval Treaty's "escalator clause" limit of standard displacement. Four vessels, , , , and , were completed; two more, and , were laid down but canceled in 1945 and 1958, respectively, before completion, and both hulls were scrapped in 1958–1959. The four ''Iowa''-class ships were the last battleships commissioned in the US Navy. All older US battleships were decommissioned by 1947 and stricken from the ''Naval Vessel Register'' (NVR) by 1963. Between the mid-1940s and the early 1990s, the ''Iowa''-class battleships fought in four major US wars. In the Pacific Theater of World War II, they served primarily as fas ...

General Board Of The United States Navy
The General Board of the United States Navy was an advisory body of the United States Navy, somewhat akin to a naval general staff and somewhat not. The General Board was established by general order 544, issued on March 13, 1900 by Secretary of the Navy John Davis Long. The order was officially recognized by Congress in 1916. The General Board was disbanded in 1951. Origins "The war with Spain had underlined the need for adequate staff work and the success of the War Board had pointed the way for the future. Among the most persistent advocates of a general staff for the Navy was Captain Henry C. Taylor. He had first laid plans for such a staff before Roosevelt in May 1897; now in 1900 he brought the idea once more to the attention of Secretary Long. Long, however, was reluctant to risk a fight with his entrenched bureau chiefs, hesitant about allowing the professional officers wide powers outside civilian control, and rightly dubious whether Congress could be brought to ap ...

Materiel
Materiel (; ) refers to supplies, equipment, and weapons in military supply-chain management, and typically supplies and equipment in a commercial supply chain context. In a military context, the term ''materiel'' refers either to the specific needs (excluding manpower) of a force to complete a specific mission, or the general sense of the needs (excluding manpower) of a functioning army. An important category of materiel is commonly referred to as ordnance, especially concerning mounted guns (artillery) and the shells it consumes. Along with fuel, and munitions in general, the steady supply of ordnance is an ongoing logistic challenge in active combat zones. Materiel management consists of continuing actions relating to planning, organizing, directing, coordinating, controlling, and evaluating the application of resources to ensure the effective and economical support of military forces. It includes provisioning, cataloging, requirements determination, acquisition, distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SYSCOM
The systems commands, abbreviated as SysCom or SYSCOM, are the materiel agencies of the United States Department of the Navy, responsible for the design, construction, and maintenance of military systems such as ships, aircraft, facilities, and weapons. The systems commands replaced the Navy bureau system in 1966 and report to the Assistant Secretary of the Navy for Research, Development and AcquisitionASN RD&A. The current Navy systems commands are: *Naval Sea Systems Command (NAVSEA) *Naval Air Systems Command (NAVAIR) *Naval Information Warfare Systems Command (NAVWAR) (formerly SPAWAR), *Naval Facilities Engineering Systems Command (NAVFAC) *Naval Supply Systems Command (NAVSUP) *Marine Corps Systems Command (MCSC) The Office of Naval Research is sometimes grouped with the systems commands, although it has a different mission geared towards scientific research rather than weapon systems development and acquisition. Function and organization Each of the systems commands pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Systems Engineering
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their enterprise life cycle, life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful Function (engineering), function. Issues such as requirements engineering, reliability, logistics, coordination of different teams, testing and evaluation, maintainability and many other Discipline (academia), disciplines necessary for successful system design, development, implementation, and ultimate decommission become more difficult when dealing with large or complex projects. Systems engineering deals with work-processes, optimization methods, and risk management tools in such projects. It overlaps technical ...
