Cromwell Tank
The Cromwell tank, officially Tank, Cruiser, Mk VIII, Cromwell (A27M), was one of the series of cruiser tanks fielded by Britain in the Second World War. Named after the English Civil War–era military leader Oliver Cromwell, the Cromwell was the first tank put into service by the British to combine high speed from a powerful, reliable engine (the Rolls-Royce Meteor) and reasonable vehicle armour, armour. The intended dual-purpose high-velocity gun could not be fitted in the turret, so a medium-velocity dual-purpose gun was fitted instead. Further development of the Cromwell combined with a high-velocity gun led to the Comet tank. The name "Cromwell" was initially applied to three vehicles during development. Early Cromwell development led to the creation of the A24 Cavalier. Later Cromwell development led to the creation of the competing Centaur tank (officially the ''Tank, Cruiser, Mk VIII, Centaur (A27L)''). This was closely related to the Cromwell, both vehicles being exter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovington Tank Museum
The Tank Museum (previously the Bovington Tank Museum) is a collection of armoured fighting vehicles at Bovington Camp in Dorset, South West England. It is about north of the village of Wool, Dorset, Wool and west of the major port of Poole. The collection traces the history of the tank with almost 300 vehicles on display. It includes Tiger 131, the only working example of a German Tiger I tank, and a British First World War Mark I tank, Mark I, the world's oldest surviving combat tank. It is the museum of the Royal Tank Regiment and the Royal Armoured Corps and is a charitable organization, registered charity. History The writer Rudyard Kipling visited Bovington in 1923 and, after viewing the damaged tanks that had been salvaged at the end of the World War I, First World War, recommended that a museum be set up. A shed was established to house the collection but was not opened to the general public until 1947. George Forty, who was appointed director of the museum in 1982, e ...

Besa Machine Gun
The Besa machine gun was a British version of the Czechoslovak ZB-53 air-cooled, belt-fed machine gun (called the TK vz. 37 in the Czechoslovak army"TK" from ''těžký kulomet'' "heavy machine gun"; "vz" from ''vzor'' "Model"). The name came from the Birmingham Small Arms Company (BSA), who signed an agreement with '' Československá zbrojovka'' to manufacture the gun in the UK. The War Office ordered the weapon in 1938 and production began in 1939, after modifications. It was used extensively by the armed forces of United Kingdom during the Second World War as a mounted machine gun for tanks and other armoured vehicles as a replacement for the heavier, water-cooled Vickers machine gun. Although it required a rather large opening in the tank's armour, it was reliable. Development and use Although British forces used the .303 in rimmed round for rifles and machine guns, the ZB-53 had been designed for the German 7.92×57mm Mauser round; referred to by the British as th ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A24 Cavalier
The Tank, Cruiser, Mk VII Cavalier (A24) was an interim design of British cruiser tank during the Second World War. It was derived as a follow on from the Nuffield's A15 Crusader tank as it was expected to enter production in 1942. A parallel effort under Leyland Motors and Birmingham Railway Carriage and Wagon Company to the same specification resulted in the A27 Cromwell and Centaur tanks which was accepted for service in preference to the Cavalier. Development Early Development Development of the Cavalier initially started as development of the Cromwell tank. In mid-1940, the British were considering which tank should follow on from the new cruiser tanks then being developed. A specification was drawn up by the Directorate of Tanks and Transport which included the 57 mm QF 6 pounder gun. This led to General Staff specification A23 for a cruiser version of the A22 Churchill tank from Vauxhall, and A24 from Nuffield Mechanization & Aero Limited based upon their Cr ...

Comet Tank
The Comet tank or Tank, Cruiser, Comet I (A34) was a British cruiser tank that first saw use near the end of the World War II, Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank with a lower profile, partly-cast metal, cast turret which mounted the new Ordnance QF 17 pdr#77 mm HV, 77 mm HV gun. This was a smaller version of the 17 pdr anti-tank gun firing the same 76.2 mm (3") projectiles, albeit with a lighter charge, and was effective against late-war German tanks, including the Panther tank, Panther and Tiger I, Tiger. The Comet rendered the Cruiser Mk VIII Challenger obsolete and was an interim solution until the completely new design Centurion tank was available. When firing armour-piercing discarding sabot, APDS rounds, the 77 mm HV was superior in armour penetration capability to the 75 mm KwK 42 gun of the equivalent Axis tank, the Panther. The Comet entered active servic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vehicle Armour
Military vehicles are commonly armoured (or armored; American and British English spelling differences#-our, -or, see spelling differences) to withstand the impact of Fragmentation (weaponry), shrapnel, bullets, Shell (projectile), shells, Rocket (weapon), rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships. Civilian vehicles may also be armoured. These vehicles include cars used by officials (e.g., Official state car, presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian Armored car (valuables), armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the Carjacking, hijacking of the cargo. Armour may also be used in vehicles to protect from threats other than a deliberate attack. Some spacecraft are equipped with specialised armour to protect them against im ...

Oliver Cromwell
Oliver Cromwell (25 April 15993 September 1658) was an English statesman, politician and soldier, widely regarded as one of the most important figures in British history. He came to prominence during the Wars of the Three Kingdoms, initially as a senior commander in the Parliamentarian army and latterly as a politician. A leading advocate of the execution of Charles I in January 1649, which led to the establishment of the Commonwealth of England, Cromwell ruled as Lord Protector from December 1653 until his death. Although elected Member of Parliament (MP) for Huntingdon in 1628, much of Cromwell's life prior to 1640 was marked by financial and personal failure. He briefly contemplated emigration to New England, but became a religious Independent in the 1630s and thereafter believed his successes were the result of divine providence. In 1640 he was returned as MP for Cambridge in the Short and Long Parliaments. He joined the Parliamentarian army when the First Engl ...

English Civil War
The English Civil War or Great Rebellion was a series of civil wars and political machinations between Cavaliers, Royalists and Roundhead, Parliamentarians in the Kingdom of England from 1642 to 1651. Part of the wider 1639 to 1653 Wars of the Three Kingdoms, the struggle consisted of the First English Civil War and the Second English Civil War. The Anglo-Scottish war (1650–1652), Anglo-Scottish War of 1650 to 1652 is sometimes referred to as the ''Third English Civil War.'' While the conflicts in the three kingdoms of England, Kingdom of Scotland, Scotland and Kingdom of Ireland, Ireland had similarities, each had their own specific issues and objectives. The First English Civil War was fought primarily over the correct balance of power between Parliament of England, Parliament and Charles I of England, Charles I. It ended in June 1646 with Royalist defeat and the king in custody. However, victory exposed Parliamentarian divisions over the nature of the political settlemen ...

Cruiser Tank
The cruiser tank (sometimes called cavalry tank or fast tank) was a British tank concept of the interwar period for tanks designed as modernised armoured and mechanised cavalry, as distinguished from infantry tanks. Cruiser tanks were developed after medium tank designs of the 1930s failed to satisfy the Royal Armoured Corps. The cruiser tank concept was conceived by Giffard Le Quesne Martel, who preferred many small light tanks to swarm an opponent, instead of a few expensive and unsatisfactory medium tanks. "Light" cruiser tanks (for example the Cruiser Mk I) carried less armour and were correspondingly faster, whilst "heavy" cruiser tanks (such as the Cruiser Mk II) had more armour and were slightly slower. The British cruiser tank series started in 1938 with the A9 and A10 cruiser tanks, followed by the A13, A13 Mark II, the A13 Mark III Covenanter in 1940 and the A15 Crusader which entered service in 1941. The Crusader was superseded by the A27 Cromwell in 1944. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
