Crusader Tank
Crusader, in full "Tank, Cruiser Mk VI, Crusader", also known by its List of tanks of the United Kingdom#General Staff numbers, General Staff number A.15, was one of the primary British cruiser tanks during the early part of the World War II, Second World War. Over 5,000 tanks were manufactured and they made important contributions to the British victories during the North African campaign. The Crusader only saw active service in Africa but the chassis of the tank was modified to create anti-aircraft, fire support, observation, communication, bulldozer and recovery vehicle variants. The first Crusader Mark I tanks entered service in 1941 and though manoeuvrable, they were relatively lightly armoured and under-armed. The following Crusader Mark II had a maximum armour of . The main armament for the Crusader Mark I and IIs was a 40 mm Ordnance QF 2-pounder gun; the following Crusader Mark III was fitted with a 57 mm Ordnance QF 6-pounder gun at the expense of one member ...

The 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 display. 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. History The writer Rudyard Kipling visited Bovington in 1923 and, after viewing the damaged tanks that had been salvaged at the end of the 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, expanded and modernized the collection. He retired in 1993 afte ...

Siege Of Tobruk
The siege of Tobruk () took place between 10 April and 27 November 1941, during the Western Desert campaign (1940–1943) of the World War II, Second World War. An Allies of World War II, Allied force, consisting mostly of the 9th Division (Australia), 9th Australian Division, commanded by Lieutenant-General Leslie Morshead, was besieged in the North African port of Tobruk by German and Italian forces. The tenacious defenders quickly became known as the Rats of Tobruk. After 231 days, they were finally relieved by the British Eighth Army (United Kingdom), Eighth Army. In late 1940, the Allies had defeated the Italian 10th Army during Operation Compass and trapped the remnants at Beda Fomm. On 22 January 1941, Tobruk's Italian garrison surrendered. But in early 1941, much of the British Western Desert Force was sent to the German invasion of Greece, Greek and Syria–Lebanon campaign, Syria–Lebanon campaigns, leaving only a skeleton force short of equipment and supplies. ...

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 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 ...

Gun Mantlet
A gun mantlet is an armour plate or shield attached to an armoured fighting vehicle's gun, protecting the opening through which the weapon's barrel projects from the hull or turret armour and, in many cases, ensuring the vulnerable warhead of a loaded shell does not protrude past the vehicle's armour. On many tanks during World War II, the gun mantlet covered both the main gun and any coaxial armament, and had the thickest armour on the vehicle. However, in many late Cold War and post-Cold War tank designs, the gun mantlet became one of the weaker parts of a vehicle's turret armour and thus a weakness. This was because as many mantlet designs were attached directly to the gun, it drastically increased the weight of the whole gun system and the amount of effort needed to elevate and depress it. This was an issue for gun stabilizers as they proved to be less efficient and accurate in keeping the gun steady with the added weight of the mantlet. Therefore, as seen in tanks such a ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th century, these hoods were known as turrets. Modern warships have gun-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser Mk IV
The Cruiser Tank Mk IV ( A13 Mk II) was a British cruiser tank of the Second World War. It followed directly on from the Tank, Cruiser, Mk III (A13 Mk I). The first Mk IVs were Mk IIIs with extra armour fitted to the turret. Later Mk IVAs were built with the complete extra armour. The tank was used in France in 1940 and in the early part of the war in North Africa, before being withdrawn from service. A fast vehicle compared to other British tanks of the early part of the war, it was probably the best cruiser tank Britain had in 1940. In total, 955 of these tanks were built. Design and development Britain became interested in fast tanks after observing the Soviet BT tanks during the 1936 Red Army manoeuvres. The BT was based on the revolutionary designs of American J. Walter Christie and a team from Morris Motors was sent to the United States to purchase a Christie tank and the rights to build more. The tank was given the General Staff designation "A13E1" and was delivered i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cruiser Mk III
The Tank, Cruiser, Mk III, also known by its General Staff specification number A13 Mark I, was a British cruiser tank of the Second World War. It was the first British cruiser tank to use the Christie suspension system, which gave higher speeds and better cross-country performance; previous cruiser tank models had used triple wheeled bogie suspension. Design and development British cruiser tank design began with the Mk I and somewhat heavier Mk II in the mid-1930s. Just as prototypes were arriving in 1936, General Giffard LeQuesne Martel, a pioneer in tank design who had published works on armoured warfare and pioneered the lightly armoured "tankette" to enhance infantry mobility, became Assistant Director of Mechanization at the War Office.Milsom Later that year, Martel witnessed demonstrations of Soviet tank designs, including the BT tank, which had been influenced by American J. Walter Christie's work. Martel urged the adoption of the Christie suspension and Christie' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process. It is a term used in a variety of contexts, including semantics, design, electronics, and Software prototyping, software programming. A prototype is generally used to evaluate a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. Physical prototyping has a long history, and paper prototyping and virtual prototyping now extensively complement it. In some design workflow models, creating a prototype (a process sometimes called materialization) is the step between the Formal specification, formalization and the evaluation of an idea. A prototype can also mean a typical example of something such as in the use of the derivation prototypical. This is a useful term in identifying objects, behaviours and concepts which are considered the accepted norm and is analogous with terms ...

London, Midland And Scottish Railway
The London, Midland and Scottish Railway (LMSIt has been argued that the initials LMSR should be used to be consistent with London and North Eastern Railway, LNER, Great Western Railway, GWR and Southern Railway (UK), SR. The London, Midland and Scottish Railway's corporate image used LMS, and this is what is generally used in historical circles. The LMS occasionally also used the initials LM&SR. For consistency, this article uses the initials LMS.) was a British railway company. It was formed on 1 January 1923 under the Railways Act 1921, which required the grouping of over 120 separate railways into four. The companies merged into the LMS included the London and North Western Railway, the Midland Railway, the Lancashire and Yorkshire Railway (which had previously merged with the London and North Western Railway on 1 January 1922), several Scottish railway companies (including the Caledonian Railway), and numerous other, smaller ventures.

Covenanter Tank
The Cruiser tank Mk V or A13 Mk III Covenanter was a British cruiser tank of the Second World War. The Covenanter was the first cruiser tank design to be given a name. Designed by the London, Midland and Scottish Railway as a better-armoured replacement for the Cruiser Mark IV, it was ordered into production in 1939 before pilot models were built. Problems with the design became apparent only after production was under way. The tank equipped various British armoured divisions for home defence and training. It never left the UK as poor engine cooling caused the Mk I to Mk III to be declared unfit for overseas service, especially in hot climates. This was rectified in the Mk IV after many corrective actions were undertaken but, by February 1944, it was declared obsolete. More than 1,700 of the type were built. It was named after the Covenanters, a Scottish religious and political movement at the time of the Wars of the Three Kingdoms. Development In 1938, the War Office had issu ...

M4 Sherman
The M4 Sherman, officially medium tank, M4, was the medium tank most widely used by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth, Soviet Union, and other Allied Nations. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman tank evolved from the M3 Lee, a medium tank developed by the United States during the early years of World War II. The M3, also known by its service names "Grant" and "Lee," was characterized by a unique design that featured the main armament mounted in a side sponson. The Grant variant, used by British forces, employed a lower-profile turret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
