Sovetsky Soyuz-class Battleship
The ''Sovetsky Soyuz''-class battleships (Project 23, , ), also known as "Stalin's Republics", were a class of battleships begun by the Soviet Union in the late 1930s but never brought into service. They were designed in response to the s being built by Germany. Only four hulls of the fifteen originally planned had been laid down by 1940, when the decision was made to cut the program to only three ships to divert resources to an expanded army rearmament program. These ships would have rivaled the Imperial Japanese and America's planned in size if any had been completed, although with significantly weaker firepower: nine guns compared to the nine guns of the Japanese ships and a dozen on the ''Montana''s. The failure of the Soviet armor plate industry to build Krupp cemented armour, cemented armor plates thicker than would have negated any advantages from the ''Sovetsky Soyuz'' class's thicker armor in combat. Construction of the first four ships was plagued with difficulti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Project 24
A project is a type of assignment, typically involving research or design, that is carefully plan, planned to achieve a specific objective. An alternative view sees a project managerialism, managerially as a sequence of events: a "set of interrelated tasks to be executed over a fixed period and within certain cost and other limitations". A project may be a temporary (rather than a permanent) social system (work systems, work system), possibly staffed by teams (within or across organizations) to accomplish particular Task (project management), tasks under Time limit, time constraints. A project may form a part of wider programme management or function as an ''ad hoc'' system. Open-source software "projects" or artists' musical "projects" (for example) may lack defined team-membership, precise planning and/or time-limited durations. Overview The word ''project'' comes from the Latin word ''projectum'' from the Latin verb ''proicere'', "before an action", which in turn comes ...

Flying Boat
A flying boat is a type of seaplane with a hull, allowing it to land on water. It differs from a floatplane in having a fuselage that is purpose-designed for flotation, while floatplanes rely on fuselage-mounted floats for buoyancy. Though a flying boat’s fuselage provides buoyancy, it may also utilize under-wing floats or wing-like hull projections (called sponsons) for additional stability. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 20th century, exceeded in size only by bombers developed during the Second World War. Their advantage lay in using water instead of expensive land-based runways, making them the basis for international airlines in the interwar period. They were also commonly used as maritime patrol aircraft and air-s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second London Naval Treaty
The Second London Naval Treaty was an international treaty signed as a result of the Second London Naval Disarmament Conference held in London. The conference started on 9 December 1935 and the treaty was signed by the participating nations on 25 March 1936. Treaty The signatories were France, the United States, and the major constituents of the British Empire: Australia, Canada, India, New Zealand, and the United Kingdom (on behalf of itself and "all parts of the British Empire which are not separate Members of the League of Nations"). Two Commonwealth Dominions declined to sign: South Africa and the Irish Free State, the latter because it had no navy. Japan, a signatory of the First London Naval Treaty and already at war on the Asian mainland, withdrew from the conference on 15 January. Italy also declined to sign the treaty, largely as a result of the controversy over its invasion of Abyssinia (Ethiopia); Italy was under sanctions from the League of Nations. The confere ...

Anti-aircraft Warfare
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface (Submarine#Armament, submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense, Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Navy
The Soviet Navy was the naval warfare Military, uniform service branch of the Soviet Armed Forces. Often referred to as the Red Fleet, the Soviet Navy made up a large part of the Soviet Union's strategic planning in the event of a conflict with the opposing superpower, the United States, during the Cold War (1945–1991). The Soviet Navy played a large role during the Cold War, either confronting the North Atlantic Treaty Organization in western Europe or power projection to maintain its Warsaw Pact, sphere of influence in eastern Europe. The Soviet Navy was divided into four major fleets: the Soviet Northern Fleet, Northern, Pacific Fleet (Russia), Pacific, Black Sea Fleet, Black Sea, and Baltic Fleet, Baltic Fleets, in addition to the Leningrad Naval Base, which was commanded separately. It also had a smaller force, the Caspian Flotilla, which operated in the Caspian Sea and was followed by a larger fleet, the 5th Operational Squadron, 5th Squadron, in the Mediterranean Sea. The ...

Gibbs & Cox
Gibbs & Cox is an American naval architecture firm that specializes in designing surface warships. Founded in 1922 in New York City, Gibbs & Cox is now headquartered in Arlington, Virginia. The firm has offices in New York City; Washington, D.C.; Newport News, Virginia; Philadelphia, Pennsylvania; and New Orleans, LA. In 2003, more than 150 warships built to the firm's designs, including 60 percent of the U.S. Navy's surface combatant fleet, were on active duty in nearly 20 navies. History The firm was founded as "Gibbs Brothers" by self-taught naval architect William Francis Gibbs and his brother Frederic H. Gibbs. The name was changed when architect Daniel H. Cox of Cox & Stevens joined the firm in 1929. In 1931, Gibbs & Cox designed the MV ''Savarona'', a large luxury yacht.

Ship types included destroyers, LST landing craft, minesweepers, ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Breaking
Ship breaking (also known as ship recycling, ship demolition, ship scrapping, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships either as a source of Interchangeable parts, parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about its use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Barbarossa
Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A-A line. The attack became the largest and costliest military offensive in history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers. The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it w ...

Krupp Cemented Armour
Krupp armour was a type of steel naval armour used in the construction of capital ships starting shortly before the end of the nineteenth century. It was developed by Germany's Krupp Arms Works in 1893 and quickly replaced Harvey armour as the primary method of protecting naval ships, before itself being supplanted by the improved Krupp cemented armour. Original Krupp armour The initial manufacturing of Krupp armour was very similar to Harveyized armour; however, while the Harvey process generally used nickel-steel, the Krupp process added as much as 1% chromium to the alloy for additional hardness. Even though use of chromium in steels predated the use of nickel, the necessary amount of chromium complicated steel case-hardening due to its ability to crack (hence water tempering had to be replaced with slower oil-tempering). Also, while Harveyized armour was carburized by heating the steel and placing charcoal on its surface for long periods (often several weeks), Krupp armou ...

Imperial Japanese
The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation state that existed from the Meiji Restoration on January 3, 1868, until the Constitution of Japan took effect on May 3, 1947. From 1910 to 1945, it included the Japanese archipelago, the Kurils, Karafuto, Korea, and Taiwan. The South Seas Mandate and concessions such as the Kwantung Leased Territory were ''de jure'' not internal parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the formalized surrender was issued on September 2, 1945, in compliance with the Potsdam Declaration of the Allies, and the empire's territory subsequently shrunk to cover only the Japanese archipelago resembling modern Japan. Under the slogans of "Enrich the Country, Strengthen the Armed Forces" and "Promote Industry" which followed the Boshin War and the restoration of power to the emperor from the shogu ...

Laid Down
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in a ship's life; the others are launching, commissioning, and decommissioning. Earlier, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication" and is the ceremonial beginning of the ship's life, although s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
