USS Wagner
USS Wagner (DER-539) was a ''John C. Butler''-class destroyer escort in service the United States Navy from 1955 to 1960. She had been launched in 1943 but her construction was suspended until 1954. She was completed as a radar picket ship. After only five years of service she was laid up and later sunk as a target in 1975. History ''Wagner'' (DE-539) was laid down on 8 November 1943 at Boston, Massachusetts, by the Boston Navy Yard; launched on 27 December 1943 in a double ceremony with ; and sponsored by Mrs. Alfred Thomas. The ship was named for Seaman second class William Daniel Wagner, a navy armed guard on SS ''Steel Navigator'' when the ship was sunk by German submarine U-610 on 19 October 1942. Due to adjustments of wartime priorities and postwar cutbacks, construction of ''Wagner'' was suspended on 17 February 1947, while the ship was 61.5 percent complete. Towed to the Naval Industrial Reserve Shipyard, Boston, Massachusetts, the ship lay " mothballed" for the next ...

Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil-fuels, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Naval Industrial Reserve Shipyard
A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications ( brown-water navy), open-ocean applications ...

Navy List
A Navy Directory, formerly the Navy List or Naval Register is an official list of naval officers, their ranks and seniority, the ships which they command or to which they are appointed, etc., that is published by the government or naval authorities of a country. Background The Navy List fulfills an important function in international law in that warships are required by article 29 of the United Nations Convention on the Law of the Sea to be commanded by a commissioned officer whose name appears in the appropriate service list. Past copies of the Navy List are also important sources of information for historians and genealogists. The Navy List for the Royal Navy is no longer published in hard-copy. The Royal Navy (United Kingdom) publishes annual lists of active and reserve officers, and biennial lists of retired officers. As of 2015, the Navy List of the Royal Navy has been renamed as the 'Navy Directory'. The equivalent in the United States Navy is the Naval Register, whic ...

Sabine Pass, Texas
Sabine Pass is a neighborhood in Port Arthur, Texas. It lies at Sabine Pass, on the west bank of the Sabine River, the border between Louisiana and Texas, and was incorporated in 1861. Formally annexed by Port Arthur in 1978, Sabine Pass has its own school district, post office, water district, and port authority. Police and fire protection is provided by the Port Arthur city government. The Port Arthur Convention and Visitors Bureau stated that Sabine Pass is "often regarded as" being a "self-contained" community. Sabine Pass was the site of two naval battles, the First Battle of Sabine Pass, and the Second Battle of Sabine Pass, as well as land skirmishes that occurred around the historic Sabine Pass Lighthouse during the Civil War. History In 1832, Thomas Corts (of England) and John McGaffey (of New Hampshire) were among the first settlers of the Sabine Pass area. Stephen Hendrickson Everitt (1806–1844) wrote a letter to Republic of Texas President Mirabeau B. Lamar on Ma ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Contiguous Radar Coverage System
Continental Air Defense Command (CONAD) was a Unified Combatant Command of the United States Department of Defense, tasked with air defense for the Continental United States. It comprised Army, Air Force, and Navy components. It included Army Project Nike missiles (Ajax and Hercules) anti-aircraft defenses and USAF interceptors (manned aircraft and BOMARC missiles). The primary purpose of continental air defense during the CONAD period was to provide sufficient attack warning of a Soviet bomber air raid to ensure Strategic Air Command could launch a counterattack without being destroyed. CONAD controlled nuclear air defense weapons such as the 10 kiloton W-40 nuclear warhead on the CIM-10B BOMARC. The command was disestablished in 1975, and Aerospace Defense Command became the major U.S. component of North American Air Defense Command (NORAD). Background As the new U.S. Air Force was being established in 1947, consideration of a joint command for air defense began. After t ...

Distant Early Warning Line
The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the northern Arctic region of Canada, with additional stations along the north coast and Aleutian Islands of Alaska (see Project Stretchout and Project Bluegrass), in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming bombers of the Soviet Union during the Cold War, and provide early warning of any sea-and-land invasion. The DEW Line was the northernmost and most capable of three radar lines in Canada and Alaska. The first of these was the joint Canadian-United States Pinetree Line, which ran from Newfoundland to Vancouver Island just north of the Canada–United States border, but even while it was being built there were concerns that it would not provide enough warning time to launch an effective counterattack. The Mid-Canada Line (MCL) was proposed as an inexpensive solution using bistatic radar. This provided a "trip w ...

Roosevelt Roads
Roosevelt Roads Naval Station is a former United States Navy base in the town of Ceiba, Puerto Rico. The site operates today as José Aponte de la Torre Airport, a public use airport. History In 1919, future US President Franklin D. Roosevelt, then Assistant Secretary of the Navy, toured Puerto Rico, visiting Ceiba. When he returned to the White House, he expressed a liking for the terrain where the base was to be located. This was during the World War I era, and the US could benefit from an air field in Ceiba. While Puerto Rico is a Commonwealth (U.S. insular area), Commonwealth, its territorial rights belong to the US, which made it feasible for the US government to build an air base in Ceiba. It took many years for the US to become convinced of the need for an air base in Ceiba. When Adolf Hitler and Nazi Germany began to invade other European countries, the US, led by then President Roosevelt, considered the idea of a naval air station in Ceiba. With war in the European ...

Shakedown Cruise
Shakedown cruise is a nautical term in which the performance of a ship is tested. Generally, shakedown cruises are performed before a ship enters service or after major changes such as a crew change, repair or overhaul. The shakedown cruise simulates working conditions for the vessel, for various reasons. For most new ships, the major reasons are to familiarise a crew with a new vessel and to ensure all of the ship's systems are functional. Overview If the ship is the first of its class, it will likely also be performing its sea trials, a test of its performance. In this context, 'shakedown cruise' and 'sea trials' may be used interchangeably, though each has a slightly different meaning. In such a case, it is likely that the ship's systems will be pushed to redline, or maximum capacity, to demonstrate the class's speed and other important traits. Until bested by another ship of the same class, this shakedown performance will be the standard of the class's capabilities, a ...
