Tortoise (tank)
The Tortoise heavy assault tank (A39) was a British heavy assault gun design developed during the Second World War, but never put into mass production. It was developed for the task of clearing heavily fortified areas such as the Siegfried Line and as a result favoured armour protection over mobility. Although heavy, at 78 tons, and not readily transported, it was considered reliable and a good gun platform. Only a few prototypes of the Tortoise had been produced by the end of the war. After testing was complete, one was retained for preservation and the others disposed of. Development In the early part of 1943, the Allied forces anticipated considerable resistance in the projected future invasion of Europe, with the enemy fighting from heavily fortified positions such as the Siegfried Line. As a result, a new class of vehicles emerged, in the shape of assault tanks, which placed maximum armour protection at a higher priority than mobility. Initially, work was concentrate ...

Ordnance QF 32 Pounder
The Ordnance QF 32 pounder or (32-pdr) was a British 94 mm gun, initially developed as a replacement for the Ordnance QF 17-pounder, Ordnance QF 17-pdr anti-tank gun. The only use of the 32-pounder was as the armament for the pilot vehicles of the Tortoise heavy assault tank. Development Development started in October 1942, due to a Chief of the General Staff (United Kingdom), General Staff order for a successor to the Ordnance QF 17-pounder, 17-pdr gun. Basic requirements involved the new gun to be "at least 25% more effective" than the 17-pdr. Initial focus was on development of a 55-pdr gun, although advancements in 17-pdr ammunition meant the advantages that would be secured by the 55-pdr were no longer as desirable, while the 55-pdr would suffer from considerable disadvantages such as the difficulties in the handling and stowage of ammunition. Other options considered included a 76 mm (3-inch) 17-pdr firing a Armour-piercing_ammunition#APCR_and_HVAP, Armour Piercing ...

79th Armoured Division (United Kingdom)
The 79th Armoured Division was a specialist armoured division of the British Army created during the Second World War. The division was created as part of the preparations for the Normandy invasion on 6 June 1944, D-Day. Major-General Percy Hobart commanded the division and was in charge of the development of armoured vehicles that were solutions to problems of the amphibious landing on the defended French coastline; these unusual-looking tanks it developed and operated were known as "Hobart's Funnies". They included tanks that floated, could clear mines, destroy defences, carry and lay bridges, and roadways. The practical use of these specialist tanks was confirmed during the landings on the beaches. Its vehicles were distributed as small units across the divisions taking part in the landings and subsequent operations. The division remained in action during the North-west European Campaign, providing specialised support during assaults to the 21st Army Group and, occasionall ...

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 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. 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 ...

Bovington 146 Tortoise 1
Bovington Camp () is a British Army military base in Dorset, England. Together with Lulworth Camp it forms part of Bovington Garrison. The garrison is home to The Armour Centre and contains two barracks complexes and two forest and heathland training areas that support Phase Two training for soldiers of the Royal Armoured Corps and trade training for the Household Cavalry Regiment as well as other armoured units. It also houses The Tank Museum on its property. It is run by the resident RSM W01 Joshua Wisdom History The camps at Bovington and Lulworth were originally established in 1899 as an infantry training area and ranges. In 1916, they became training camps for the Heavy Branch of the Machine Gun Corps which relocated from Norfolk. The Heavy Branch was responsible for the operation of the tank in the British Army. In 1917 the Heavy Branch split from the Machine Gun Corps to become the Tank Corps, with the Depot and Central Schools being based at Bovington. In 1937 the Cent ...

Trunnion
A trunnion (from Old French "''trognon''", trunk) is a cylindrical protrusion used as a mounting or pivoting point. First associated with cannons, they are an important military development. Alternatively, a trunnion is a shaft that positions and supports a tilting plate. This is a misnomer, as in reality it is a cradle for the true trunnion. In mechanical engineering (see the trunnion bearing section below), it is one part of a rotating joint where a shaft (the trunnion) is inserted into (and turns inside) a full or partial cylinder. Medieval history In a cannon, the trunnions are two projections cast just forward of the center of mass of the cannon and fixed to a two-wheeled movable gun carriage. As they allowed the muzzle to be raised and lowered easily, the integral casting of trunnions is seen by military historians as one of the most important advances in early field artillery. With the creation of larger and more powerful siege guns in the early 15th century, a n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panther Tank
The Panther tank, officially ''Panzerkampfwagen V Panther'' (abbreviated PzKpfw V) with ordnance inventory designation: ''Sd.Kfz.'' 171, is a German medium tank of World War II. It was used on the Eastern and Western Fronts from mid-1943 to the end of the war in May 1945. On 27 February 1944 it was redesignated to just ''PzKpfw Panther'', as Hitler ordered that the Roman numeral "V" be deleted. In contemporary English-language reports it is sometimes referred to as the "Mark V". The Panther was intended to counter the Soviet T-34 medium tank and to replace the Panzer III and Panzer IV. Nevertheless, it served alongside the Panzer IV and the heavier Tiger I until the end of the war. It had excellent firepower, protection and mobility, although its reliability was less impressive. The Panther was a compromise. While having essentially the same Maybach V12 petrol (690 hp) engine as the Tiger I, it had better gun penetration, was lighter and faster, and could traverse roug ...

Self-propelled Gun
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns (tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

Casemate
A casemate is a fortified gun emplacement or armored structure from which artillery, guns are fired, in a fortification, warship, or armoured fighting vehicle.Webster's New Collegiate Dictionary When referring to Ancient history, antiquity, the term "casemate wall" means a double city wall with the space between the walls separated into chambers, which could be filled up to better withstand battering rams in case of siege (see #Antiquity: casemate wall, Antiquity: casemate wall). In its original early modern meaning, the term referred to a vaulted chamber in a fort, which may have been used for storage, accommodation, or artillery which could fire through an opening or embrasure. Although the outward faces of brick or masonry casemates proved vulnerable to advances in artillery performance, the invention of reinforced concrete allowed newer designs to be produced well into the 20th century. With the introduction of ironclad warships, the definition was widened to include a prot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T14 Heavy Tank
The Assault Tank T14 was a joint project between the United States and the United Kingdom with the goal being to produce a universal infantry tank. The T14 project never came to fruition, as a pilot model was not delivered to the UK until 1944 by which time the British Churchill tank had been in service for two years and greatly improved over its initial model. US efforts working on a similarly well-armoured tank but with a higher speed for use other than in infantry support led to the T20 Medium Tank. Design and development In 1941, the head of the United States Ordnance Department travelled to Britain to learn of their experience, ideas and requirements for the future. Among the discussion was the possibility of designing a well-armed and armoured combat vehicle, one that was stronger than the British Churchill infantry tank then in production. The tank design would have a British QF 6-pounder (57 mm) or a US 75 mm gun and share many parts with the M4 Sherman; they ...
