Centaur Bulldozer
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 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 Tank, Cruiser, Mk VIII, Centaur (A27L) design. The Centaur tank was closely related to the Cromwell, both vehicles being externally similar. The Cromwell and ... [...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 and west of the major port of Poole. The collection traces the history of the tank. With almost 300 vehicles on exhibition from 26 countries it is the largest collection of tanks and the third largest collection of armoured vehicles in the world.The ''Musée des Blindés'' in France has a collection of 880 armoured vehicles, although it includes fewer tanks than Bovington. It includes Tiger 131, the only working example of a German Tiger I tank, and a British First World War 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 registered charity.

11th Armoured Division
The 11th Armoured Division was an armoured division of the British Army which was created in March 1941 during the Second World War. The division was formed in response to the unanticipated success of the German panzer divisions. The 11th Armoured was responsible for several major victories in the Battle of Normandy from in the summer of 1944, shortly after the Normandy landings, and it participated in the Allied advance from Paris to the Rhine, the Rhine crossing in March 1945. It was disbanded in January 1946 and reformed towards the end of 1950. In 1956, it was converted into the 4th Infantry Division. Background and formation The 11th Armoured Division was organized in March 1941, in Yorkshire under Northern Command, under Major-General Percy Hobart. A veteran of the Royal Tank Regiment, he had already strongly influenced the shape of the 7th Armoured Division, but his original and innovative ideas had led to his early retirement from the army. Reinstated after the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
7th Armoured Division (United Kingdom)
The 7th Armoured Division was an armoured division of the British Army that saw distinguished active service during the Second World War, where its exploits in the Western Desert Campaign gained it the ''Desert Rats'' nickname. After the Munich Agreement, the division was formed in Egypt during 1938 as the Mobile Division (Egypt) and its first divisional commander was the tank theorist Major-General Sir Percy Hobart. In February 1940, the name of the unit was changed to the 7th Armoured Division. The division fought in most major battles during the North African Campaign; later it would land and fight in the Italian Campaign during the early stages of the invasion of Italy before being withdrawn to the United Kingdom where it prepared to fight in North-west Europe. It began landing in Normandy during the afternoon of D-Day, 6 June 1944, and fought its way across Europe ending the war in Kiel and Hamburg, Germany. Although the division was disbanded during the 1950s, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Armoured Corps
The Royal Armoured Corps is the component of the British Army, that together with the Household Cavalry provides its armour capability, with vehicles such as the Challenger 2 Tank and the Scimitar Reconnaissance Vehicle. It includes most of the Army's armoured regiments, both the Royal Tank Regiment and those converted from old horse cavalry regiments.Forty p. 63. Today it comprises twelve regiments, eight regular and four reserve. Although the Household Cavalry Regiment (the Life Guards and the Blues and Royals) provide an armoured regiment, they are not part of the RAC. History The RAC was created on 4 April 1939, just before World War II started, by combining regiments from the cavalry of the line which had mechanised with the Royal Tank Corps (renamed Royal Tank Regiment). As the war went on and other regular cavalry and Territorial Army Yeomanry units became mechanised, the corps was enlarged. A significant number of infantry battalions also converted to the armoured r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Overlord
Operation Overlord was the codename for the Battle of Normandy, the Allies of World War II, Allied operation that launched the successful invasion of German-occupied Western Front (World War II), Western Europe during World War II. The operation was launched on 6 June 1944 (D-Day) with the Normandy landings. A 1,200-plane Airborne forces, airborne assault preceded an amphibious warfare, amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August. The decision to undertake a cross-channel invasion in 1944 was taken at the Washington Conference (1943), Trident Conference in Washington, D.C., Washington in May 1943. General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force, and General Bernard Montgomery was named commander of the 21st Army Group, which comprised all the land forces involved in the invasio ...

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 mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. 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 types of piston engines, as well as turbines, electric motors and other machinery. 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 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...

Cavalier Tank
The Tank, Cruiser, Mk VII Cavalier (A24) was an interim design of British cruiser tank during the Second World War. It was derived from the A15 Crusader tank and was superseded by the A27 Cromwell tank. 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 Crusader tank design. Birmingham Railway Carriage and Wagon Company (BRC&W) also submitted a design based on the Crusader. The Nuffield design used an uprated -- Liberty engine which was expected to give a top speed of .

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 Second World War, during the Western Allied invasion of Germany. The Comet was developed from the earlier Cromwell tank and mounted the new 17 pdr High Velocity (HV) (3 inch; 76.2 mm – sometimes referred to as "77 mm") gun, in a lower profile, partly-cast turret. This gun was effective against late-war German tanks, including the Panther at medium range, and the Tiger. The Comet rendered the Cruiser Mk VIII Challenger obsolete, and led to the development of the Centurion tank. When firing 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 service in January 1945 and remained in British service until 1958. In some cases, Comets sold to other countries continued to operate into the 1980s.

Vehicle Armour
Military vehicles are commonly armoured (or armored; see spelling differences) to withstand the impact of shrapnel, bullets, shells, 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., presidential limousines), reporters and others in conflict zones or where violent crime is common. Civilian armoured cars are also routinely used by security firms to carry money or valuables to reduce the risk of highway robbery or the 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 impacts from micrometeoroids or fragments of space debris. Modern aircraft powered by jet engines usually have them fitted with a sort of armour in the form of an aramid composite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oliver Cromwell
Oliver Cromwell (25 April 15993 September 1658) was an English politician and military officer who is widely regarded as one of the most important statesmen in English history. He came to prominence during the 1639 to 1651 Wars of the Three Kingdoms, first as a senior commander in the Parliamentarian army and then as a politician. A leading advocate of the execution of Charles I in January 1649, which led to the establishment of the Republican Commonwealth of England, Scotland and Ireland, he ruled as Lord Protector from December 1653 until his death in September 1658. Cromwell nevertheless remains a deeply controversial figure in both Britain and Ireland, due to his use of the military to first acquire, then retain political power, and the brutality of his 1649 Irish campaign. Educated at Sidney Sussex College, Cambridge, Cromwell was elected MP for Huntingdon in 1628, but the first 40 years of his life were undistinguished and at one point he contemplated emigration to ...
