Landing Craft Tank
The Landing Craft, Tank (LCT) (or Tank Landing Craft TLC) was an amphibious assault craft for landing tanks on beachheads. They were initially developed by the Royal Navy and later by the United States Navy during World War II in a series of versions. Initially known as the "tank landing craft" (TLC) by the British, they later adopted the U.S. nomenclature "landing craft, tank" (LCT). The United States continued to build LCTs post-war, and used them under different designations in the Korean and Vietnam Wars. Development In 1926, the first motor landing craft (MLC1) was built by the Royal Navy. It weighed 16 tons, with a draught of , and was capable of about . It was later developed into the landing craft mechanised. It was at the insistence of the British prime minister Winston Churchill in mid-1940 that the LCT was created. Its speed was on engines delivering about . Designated the LCT Mark 1, 20 were ordered in July 1940 and a further 10 in October 1940.) Mark 1 The f ...

Bofors 40 Mm Automatic Gun L/60
The Bofors 40 mm Automatic Gun L/60 (often referred to simply as the "Bofors 40 mm gun", the "Bofors gun" and the like, see name) is an anti-aircraft autocannon, designed in the 1930s by the Swedish arms manufacturer AB Bofors. The gun was designed as an intermediate anti-aircraft gun, filling the gap between fast firing close-range small calibre anti-aircraft guns and slower firing long-range high calibre anti-aircraft guns, a role which previously was filled by older outdated guns. The Bofors 40 mm L/60 was for its time perfectly suited for this role and outperformed competing designs in the years leading up to World War II in both effectiveness and reliability. It entered the export market around 1932 and was in service with 18 countries by 1939. Throughout World War II it became one of the most popular and widespread medium-weight anti-aircraft guns. It was used by the majority of the western Allies and some Axis powers such as Nazi Germany and Hungary. In th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bison Shipbuilding
Bison are large bovines in the genus ''Bison'' (Greek: "wild ox" (bison)) within the tribe Bovini. Two extant and numerous extinct species are recognised. Of the two surviving species, the American bison, ''B. bison'', found only in North America, is the more numerous. Although colloquially referred to as a buffalo in the United States and Canada, it is only distantly related to the true buffalo. The North American species is composed of two subspecies, the Plains bison, ''B. b. bison'', and the wood bison, ''B. b. athabascae'', which is the namesake of Wood Buffalo National Park in Canada. A third subspecies, the eastern bison (''B. b. pennsylvanicus'') is no longer considered a valid taxon, being a junior synonym of ''B. b. bison''. References to "woods bison" or "wood bison" from the eastern United States refer to this subspecies, not ''B. b. athabascae'', which was not found in the region. The European bison, ''B. bonasus'', or wisent, or zubr, or colloquially European buf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New York Shipbuilding
The New York Shipbuilding Corporation (or New York Ship for short) was an American shipbuilding company that operated from 1899 to 1968, ultimately completing more than 500 vessels for the U.S. Navy, the United States Merchant Marine, the United States Coast Guard, and other maritime concerns. At its peak during World War II, NYSB was the largest and most productive shipyard in the world. Its best-known vessels include the destroyer , the cruiser , the aircraft carrier , the nuclear-powered cargo ship , and a quartet of cargo-passenger liners nicknamed the ''Four Aces (passenger liners), Four Aces''. History It was founded in 1899 by Henry G. Morse (1850–2 June 1903),Not to be confused with architect Henry Grant Morse, Jr. (1884 – May 28, 1934). an engineer noted in connection with bridge design and construction and senior partner of Morse Bridge Company.

Marine Diesel Engine
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered watercraft, Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and naval warfare, warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th century. During the 20th century it was replaced by two-stroke diesel engine, two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster s ...

Gray Marine Engine
Gray Marine Motor Company was a U.S. manufacturer of marine engines between 1910 and 1967. These ranged from one to six cylinders in both gas and later diesel layouts, which were used in pleasure boats, work boats, and military craft. Gray was based in Detroit. Many fishing boats, lobsterboats, tugs and pleasure craft used Gray engines. These boats usually fell between 12 and 32 feet. Many of their engines were marinized automotive engines from Hercules, Studebaker, Pontiac, Continental, American Motors or General Motors Diesel Division. Gray also produced a line of outboard motors. Rather than a ninety-degree gearbox, a curved housing connected motor to propeller. The lower-unit housing contained a flexible inner rotating shaft. Origins Gray Marine started in 1892 and was re-branded Gray Motor Company about 1910 by O. Mulford and his partners Paul and David Gray. The engines were also used by Traffic Motor Truck Corporation of St Louis, Koehler Truck of New Jersey, Pan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeb ...

Churchill Tank
The Tank, Infantry, Mk IV (A22) Churchill was a British infantry tank used in the Second World War, best known for its heavy armour, large longitudinal chassis with all-around tracks with multiple bogies, its ability to climb steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allied tanks of the war. The origins of the Churchill's design lay in the expectation that war in Europe might be fought in conditions similar to those of the First World War, and thus emphasised the ability to cross difficult ground. The Churchill was hurried into production in order to build up British defences against a possible German invasion. The first vehicles had flaws that had to be overcome before the Churchill was accepted for wide use. After several Marks (versions) had been built, a better-armoured specification, the Mark VII, entered service with the British Army. The improved versions performed well in the later stages of the war. The Churchi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
