USS Stein
USS ''Stein'' (DE-1065) was a destroyer escort, later redesignated as a frigate (FF-1065) of the United States Navy. She was named after Tony Stein, the first Marine (of 22) to receive the Medal of Honor for action in the Battle of Iwo Jima. ''Stein'' was laid down on 1 June 1970 at Seattle, Washington, by Lockheed Shipbuilding & Construction Co.; launched on 19 December 1970; sponsored by Mrs. Rose S. Parks; and commissioned on 8 January 1972. ''Stein'' was decommissioned on 19 March 1992 and struck from the Naval Vessel Register on 11 January 1995. She was subsequently transferred to the Mexican Navy and renamed the Armada República Mexicana ''Ignacio Allende'', abbreviated ARM ''Allende''. Design and description The ''Knox''-class was an enlarged derivative of the , omitting the ''Brooke''s expensive Tartar medium range surface to air missiles and the high pressure boilers used by the ''Brooke'' and frigates. The ship was long overall and between perpendiculars, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed Shipbuilding And Construction Company
Lockheed Shipbuilding and Construction Company (a.k.a. Lockheed Shipbuilding), was a shipyard in Seattle, Washington with Yard 1 on Harbor Island and Yard 2 at what is now Jack Block Park at Seattle Terminal 5, both at the mouth of the West Waterway of Duwamish River. Yard 1 was founded in 1898 as the Puget Sound Bridge and Dredging Company, the company that built Harbor Island, and it was purchased by Lockheed in 1959. Yard 2 began operation in 1943 to build ships for the US Navy. The shipyard was permanently closed in 1988; Yard 2 was sold in 1989, and Yard 1 was sold in 1997, both to Port of Seattle. History The Lockheed Shipyard Operable Unit consisted of an shipyard facility located on the west side of Harbor Island at 2929 16th Avenue Southwest (Yard 1) and a shipyard on the North end of Terminal 5 at 2801 SW Florida St (Yard 2). The Lockheed Shipyard was a shipbuilding facility from the 1930s until 1988. Yard 1 was bounded on the north by Southwest Lander Street, on ...

Medal Of Honor
The Medal of Honor (MOH) is the United States Armed Forces' highest military decoration and is awarded to recognize American soldiers, sailors, marines, airmen, guardians and coast guardsmen who have distinguished themselves by acts of valor. The medal is normally awarded by the president of the United States, but as it is presented "in the name of the United States Congress", it is sometimes erroneously referred to as the "Congressional Medal of Honor". There are three distinct variants of the medal: one for the Department of the Army, awarded to soldiers, one for the Department of the Navy, awarded to sailors, marines, and coast guardsmen, and one for the Department of the Air Force, awarded to airmen and guardians. The Medal of Honor was introduced for the Department of the Navy in 1861, soon followed by the Department of the Army's version in 1862. The Department of the Air Force used the Department of the Army's version until they received their own distinctive version i ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...

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 ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Boiler
A boiler is a closed vessel in which fluid (generally water) is heated. The fluid does not necessarily boil. The heated or vaporized fluid exits the boiler for use in various processes or heating applications, including water heating, central heating, boiler-based power generation, cooking, and sanitation. Heat sources In a fossil fuel power plant using a steam cycle for power generation, the primary heat source will be combustion of coal, oil, or natural gas. In some cases byproduct fuel such as the carbon monoxide rich offgasses of a coke battery can be burned to heat a boiler; biofuels such as bagasse, where economically available, can also be used. In a nuclear power plant, boilers called steam generators are heated by the heat produced by nuclear fission. Where a large volume of hot gas is available from some process, a heat recovery steam generator or recovery boiler can use the heat to produce steam, with little or no extra fuel consumed; such a configuration is common ...

Surface To Air Missile
A surface-to-air missile (SAM), also known as a ground-to-air missile (GTAM) or surface-to-air guided weapon (SAGW), is a missile designed to be launched from the ground to destroy aircraft or other missiles. It is one type of anti-aircraft system; in modern armed forces, missiles have replaced most other forms of dedicated anti-aircraft weapons, with anti-aircraft guns pushed into specialized roles. The first attempt at SAM development took place during World War II, but no operational systems were introduced. Further development in the 1940s and 1950s led to operational systems being introduced by most major forces during the second half of the 1950s. Smaller systems, suitable for close-range work, evolved through the 1960s and 1970s, to modern systems that are man-portable. Shipborne systems followed the evolution of land-based models, starting with long-range weapons and steadily evolving toward smaller designs to provide a layered defence. This evolution of design increasing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RIM-24 Tartar
The General Dynamics RIM-24 Tartar was a medium-range naval surface-to-air missile (SAM), and was among the earliest surface-to-air missiles to equip United States Navy ships. The Tartar was the third of the so-called "3 T's", the three primary SAMs the Navy fielded in the 1960s and 1970s, the others being the RIM-2 Terrier and RIM-8 Talos. History The Tartar was born of a need for a more lightweight system for smaller ships, and something that could engage targets at very close range. Essentially, the Tartar was simply a RIM-2C Terrier without the secondary booster. The Tartar was never given a SAM-N-x designation, and was simply referred to as Missile Mk 15 until the unified Army-Navy designation system was introduced in 1963. The Tartar was used on a number of ships, of a variety of sizes. Initially the Mk 11 twin-arm launcher was used, later ships used the Mk 13 and Mk 22 single-arm launchers. Early versions proved to be unreliable. The Improved Tartar retrofit program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SEMAR
Semar is a character in Javanese mythology who frequently appears in wayang shadow plays. He is one of the punokawan (clowns), but is in fact divine and very wise. He is the dhanyang (guardian spirit) of Java,Geertz, 23. and is regarded by some as the most sacred figure of the wayang set. Holt, 144. He is said to be the god Sang Hyang Ismaya in human form.Budihardja, "Grepen uit de Wajang," ''Djawa'' II (1922), 22-23; cited in Holt, 145. The name Semar is said to derive from the Javanese word ''samar'' ("dim, obscure, mysterious"). He is often referred to with the honorific, "Kyai Lurah Semar" ("the venerable chief"). Description In depictions, Semar appears with a flat nose, a protruding lower jaw, a tired eye, and bulging rear, belly, and chest. He wears a checkered hipcloth, symbolizing sacredness. Like the other panakawan, the wayang kulit puppet does not have the elaborate openwork and ornamentation characteristic of the heroes In wayang wong, Semar always leans forwa ...

Mexican Navy
The Mexican Navy is one of the two independent armed forces of Mexico. The actual naval forces are called the ''Armada de México''. The ''Secretaría de Marina'' (''SEMAR'') (English: Naval Secretariat) includes both the ''Armada'' itself and the attached ministerial and civil service. The commander of the Navy is the Secretary of the Navy, who is both a cabinet minister and a career naval officer. The Mexican Navy's stated mission is "to use the naval force of the federation for external defense, and to help with internal order". As of 2020, the Navy consists of about 68,200 men and women plus reserves, over 189 ships, and about 130 aircraft.
