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 ...

HMLCT 7074
HM LCT 7074 is the last surviving Landing craft tank, Landing Craft, Tank (LCT) in the UK. LCT 7074 is an amphibious assault ship for landing tanks, other vehicles and troops on beachheads. Built in 1944 by Hawthorn Leslie and Company, Hebburn, the Mark 3 LCT 7074 was part of the 17th LCT Flotilla during Operation Neptune in June 1944. LCT 7074 was decommissioned in 1947, and used by the Master Mariners' Club of Liverpool as their club ship ''Landfall''. She served as a floating nightclub in the 60s and 70s and was acquired by the Warship Preservation Trust in the late 1990s. She was moored at Birkenhead for restoration but the Trust went into liquidation and she later sank in the dock. The vessel was raised by the National Museum of the Royal Navy in October 2014 and transported by sea to Portsmouth for restoration.

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, name) is an Anti-aircraft warfare, 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. For its time, the Bofors 40 mm L/60 was 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 of World War II, Allies and some Axis powers such as Nazi Germany and Hungary. In the po ...

Bison Shipbuilding
A bison (: bison) is a large bovine in the genus ''Bison'' (from Greek, meaning 'wild ox') 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 generally more northern wood bison, ''B. b. athabascae''. A third subspecies, the eastern bison (''B. b. pennsylvanicus'') is no longer considered a valid taxon, being a junior synonym of ''B. b. bison''. Historical references to "woods bison" or "wood bison" from the Eastern United States refer to this synonym animal (and to their eastern woodland habitat), not to ''B. b. athabascae'', which was not found in the r ...

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 '' 4 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.

Polish Navy
The Polish Navy (; often abbreviated to ) is the Navy, naval military branch , branch of the Polish Armed Forces. The Polish Navy consists of 46 ships and about 12,000 commissioned and enlisted personnel. The traditional ship prefix in the Polish Navy is ORP (). Origins The Polish Navy has its roots in naval vessels that were largely employed on Poland's main rivers in defense of trade and commerce. During the Thirteen Years' War (1454–66), Thirteen Years' War (1454–66), a small force of ships that primarily operated on rivers and lakes saw real open sea battles for the first time. At the Battle of Vistula Lagoon, a combined fleet of the Crown of the Kingdom of Poland, Kingdom of Poland and the pro-Polish Prussian Confederation decisively defeated the navy of the Teutonic Knights, and secured permanent access to the Baltic Sea. In 1454, the maritime city of Gdańsk was re-incorporated to Poland after being previously Teutonic takeover of Danzig (Gdańsk), occupied by the Teut ...

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 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 warfare. 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 or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Marine nuclear reactors, which appeared in the 1950s ...

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, Panha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
English Channel
The English Channel, also known as the Channel, is an arm of the Atlantic Ocean that separates Southern England from northern France. It links to the southern part of the North Sea by the Strait of Dover at its northeastern end. It is the busiest Sea lane, shipping area in the world. It is about long and varies in width from at its widest to at its narrowest in the Strait of Dover."English Channel". ''The Columbia Encyclopedia'', 2004. It is the smallest of the shallow seas around the continental shelf of Europe, covering an area of some . The Channel aided the United Kingdom in becoming a naval superpower, serving as a natural defence against invasions, such as in the Napoleonic Wars and in the World War II, Second World War.

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. 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 (''Seebach M ...

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 Bogie#Tracked vehicles, bogies, its ability to climb Grade (slope), steep slopes, and its use as the basis of many specialist vehicles. It was one of the heaviest Allies of World War II, 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 Mark (designation), marks (versions) had been built, a better-armoured specification, the Mark VII, entered service with the British Army. The ...
