Super-heavy Tank
A super-heavy tank or super heavy tank is any tank that is notably beyond the standard of the class heavy tank in either size or weight relative to contemporary vehicles. Programs have been initiated on several occasions with the aim of creating an extremely resilient vehicle for penetrating enemy formations without fear of being destroyed in combat; however, only a few examples were built, and there is little evidence of any super heavy tank having seen combat. Examples were designed in the First and Second World Wars, along with a few during the Cold War. History First World War left, Model of the Flying Elephant design The first super-heavy tank was designed by the Russian naval engineer Vasily Mendeleyev who worked on the project from 1911 to 1915. The tank was envisioned to be invulnerable to almost all contemporary threats but remained on paper due to its high construction cost. Following the production of their first tanks, the British "Flying Elephant" was desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TOG II
The Tank, Heavy, TOG II was a British super-heavy tank design produced in the early part of World War II in case the battlefields of northern France devolved into a morass of mud, trenches and craters as had happened during World War I. When this did not happen the tank was deemed unnecessary and the project terminated. A development of the TOG I design, only a single prototype was built before the project was dropped. History The second design to come out of the Special Vehicle Development Committee (nicknamed "The Old Gang" as it was made up of people who had worked on the original British tanks of the First World War) the TOG 2 was similar to the TOG 1 and kept many of its features. Instead of the track path arrangement of the TOG 1 which - like that of the First World War British tanks - ran up over the top of the hull and back down, the track path was lower on the return run and the doors were above the tracks. Ordered in 1940, built by Foster's of Lincoln, the prototyp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T28 Super Heavy Tank
The T28 Super Heavy Tank was an American heavily armored tank/self-propelled gun designed for the United States Army during World War II. It was originally designed to break through German defenses of the Siegfried Line, and was later considered as a possible participant in the planned invasion of the Japanese mainland. The near 100-ton vehicle was initially designated a heavy tank. It was re-designated as the 105 mm Gun Motor Carriage T95 in 1945, and then renamed in 1946 as the Super Heavy Tank T28. Only two prototypes were built before the project was terminated. Name Initially named Heavy Tank T28 when construction was authorized in 1944, the design did not fit in the usual categories of vehicles leading to reclassification.Hunnicutt p. 61 As it did not have its armament in a revolving turret, Ordnance requested a name change to 105 mm Gun Motor Carriage T95, the change becoming official in March 1945.Hunnicutt p. 62 However, due to its heavy armor and armament†...

Fall Of France
The Battle of France (french: bataille de France) (10 May – 25 June 1940), also known as the Western Campaign ('), the French Campaign (german: Frankreichfeldzug, ) and the Fall of France, was the German invasion of France during the Second World War. On 3 September 1939, France declared war on Germany following the German invasion of Poland. In early September 1939, France began the limited Saar Offensive and by mid-October had withdrawn to their start lines. German armies invaded Belgium, Luxembourg and the Netherlands on 10 May 1940. Italy entered the war on 10 June 1940 and attempted an invasion of France. France and the Low Countries were conquered, ending land operations on the Western Front until the Normandy landings on 6 June 1944. In ''Fall Gelb'' ("Case Yellow"), German armoured units made a surprise push through the Ardennes and then along the Somme valley, cutting off and surrounding the Allied units that had advanced into Belgium to meet the German armies there ...

FCM F1
The FCM F1 was a French super-heavy tank developed during the late Interbellum by the ''Forges et Chantiers de la Méditerranée'' (FCM) company. Twelve were ordered in 1940 to replace the Char 2C, but France was defeated before construction could begin, a wooden mock-up being all that was finished. The FCM F1 was large and elongated, and had two turrets: one in front and one in the back, with a single high-velocity gun in each turret. The rear turret was higher so it could Superfiring, shoot over the first one. The vehicle was intended to be heavily armoured. Its size and protection level made it by 1940, at about 140 tons the heaviest tank ever to have actually been ordered for production. Despite two engines its speed would have been low. The primary purpose of the tank was to breach German fortification lines, not to fight enemy tanks. The development path of the FCM F1 was extremely complex, due to the existence of a number of parallel super-heavy tank projects with overlappi ...

Tortoise Heavy Assault 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 ...

TOG1
The Tank, Heavy, TOG 1 was a prototype British heavy tank produced in the early part of the Second World War in the expectation that battlefields might end up like those of the First World War. It was designed so it could cross churned-up countryside and trenches. A single prototype was built, and followed by an improved model (the TOG 2), but interest faded with the successful performance of another cross-country design, the Churchill tank, and the mobile war that was being fought. History In July 1939, the Special Vehicle Development Committee was drawn up for future tank designs suitable for Great War conditions under Sir Albert Gerald Stern; who had been on the original Landship Committee and head of the Tank Supply Depot during World War I. The committee included others who had been instrumental in the development of the tank during the Great War: former Director of Naval Construction, Sir Eustace Tennyson d'Eyncourt, Major-general (retired) Sir Ernest Swinton, engine design ...

Composite Armour
Composite armour is a type of vehicle armour consisting of layers of different material such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles. HEAT had posed a serious threat to armoured vehicles since its introduction in World War II. Lightweight and small, HEAT projectiles could nevertheless penetrate hundreds of millimetres of the most resistant steel armours. The capability of most materials for defeating HEAT follows the "density law", which states that the penetration of shaped charge jets is proportional to the square root of the shaped charge liner dens ...

Rolled Homogeneous Armour
Rolled homogeneous armour (RHA) is a type of vehicle armour made of a single steel composition hot-rolled to improve its material characteristics, as opposed to layered or cemented armour. Its first common application was in tanks. After World War II, it began to fall out of use on main battle tanks and other armoured fighting vehicles intended to see front-line combat as new anti-tank weapon technologies were developed which were capable of relatively easily penetrating rolled homogeneous armour plating even of significant thickness. Today, the term is primarily used as a unit of measurement of the protection offered by armour on a vehicle (often composed of materials that may not actually contain steel, or even contain any metals) in equivalent ''millimetres of RHA'', referring to the thickness of RHA that would provide the same protection. Typically, modern composite armour can provide the same amount of protection with much thinner and lighter construction than its protectiv ...

T30 Heavy Tank
The Heavy Tank T30 was a World War II American tank project developed to counter new German tanks, such as Tiger I, Tiger II, and tank destroyers, such as the ''Jagdtiger'', or Soviet heavy tanks, such as IS-1 or IS-2. The T30 was designed at the same time as the T29 Heavy Tank. Early tanks Plans for four pilot heavy tanks were put forward in 1944; two T29 with a 105 mm gun and two T30 with a 155 mm gun. The T30 pilot models were started in April 1945 and were delivered in 1947. Apart from modifications to fit the different engine, the chassis was the same as the T29. The gun fired separate loading (shell and charge) ammunition. The loader was assisted by a spring rammer. The T30 was fitted with one of the largest guns ever used on an American tank. The high, rounded edge, turret was needed to accommodate the standing loader and large gun mount. Even then the gun could only be loaded at limited elevations. It could carry a mixed assortment of 34 T35E1 HVAP (high-vel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Object 279
The Obiekt 279, or Object 279, (Объект 279) was a Soviet experimental heavy tank developed at the end of 1959. This special purpose tank was intended to fight on cross country terrain, inaccessible to conventional tanks, acting as a heavy breakthrough tank. It was planned as a tank of the Supreme Command Reserve. Design The tank was developed at the Kirov Plant in Leningrad by a group headed by the engineer L. Troyanov. The work on the tank started in 1957, which was based on a heavy tank operational requirements developed in 1956, and a pre-production tank was completed at the end of 1959. This unique tank boasted increased cross-country capability. It featured four-track running gear mounted on two longitudinal, rectangular hollow beams, which were also used as fuel tanks. The tank suspension was hydro-pneumatic with complex hydrotransformer and three-speed planetary gearbox. The track adjuster was worm-type. The specific ground pressure of this heavy vehicle did not ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
