Query: What was the largest tank in history?
Panzerkampfwagen VIII Maus ("Mouse") was a German World War II super-heavy tank completed in late 1944. It is the heaviest fully enclosed armoured fighting vehicle ever built. Five were ordered, but only two hulls and one turret were completed before the testing grounds were captured by advancing Soviet military forces.
Even with its innovative technology and better armor protection, the T-44A still used an 85 mm ZiS-S-53 tank gun, the same as the one fitted on the T-34-85 medium tank. The army needed a new tank armed with a more powerful 100 mm gun. At the end of 1944 the designers had three types of 100 mm guns at their disposal which could considerably increase the firepower of the tank. These included the D-10 (which already proved itself in combat as it was used in SU-100 tank destroyer) as well as prototype ZiS-100 and LB-1 (LB stands for Lavrenty Beria). The T-44 tank armed with the 100 mm tank gun originally received the designation T-44B. Two projects were started, both based on the T-44A. The development of the first one started in October 1944 at the design bureau of the Stalin Ural Tank Factory No. 183, located in Nizhny Tagil. The designing stage was completed in December. The prototype was ready in February 1945. The trials conducted between March and April gave positive results and the vehicle entered service with the Red Army as T-54. The tank had almost the same hull and drive train as the T-44A. Differences included thickened front armour (120 mm on the upper section and 90 mm on the lower section) and a different hatch and vision slot for the driver. The turret had increased diameter to 1800 mm. There was thicker armour (180 mm on the front, between 90 mm and 150 mm on the sides and 30 mm on the roof). The armament included the 100 mm D-10TK tank gun as well as two 7.62 mm GWT machine guns. The tank was powered by a new V-54 12-cylinder 38.88 liter water-cooled diesel engine developing 520 hp (388 kW) at 2,000 rpm. The fuel capacity was increased (530 liters in the internal fuel tank and 165 liters in the external fuel tank). The external fuel tanks were connected to the fuel system. The rubber rollers on the roadwheels were widened. The weight was increased to 35.5 tonnes, which reduced the maximal road speed to 43.5 km/h. The maximal road operational range increased to 360 km. Because of positive results seen in trials, it was decided to modernize the tank before starting production (for more details about it see the T-54/55 article) as well as to put the new tank's turret onto two modified serial T-44A tanks. This was done in 1945 and the two prototype tanks received the designation T-44-100. One of the prototypes was armed with a D-10TK tank gun while the other one was armed with a LB-1 tank gun. Like the second generation T-44-85 prototypes, the two T-44-100 prototypes had differences between each other. One prototype had a splashboard on the glacis plate while the other did not. They both had the 12.7 mm DShK anti-aircraft heavy machine gun fitted to the loader's hatch, 6 mm thick anti-HEAT sideskirts protecting the sides and two cylindrical fuel tanks in the back which increased the fuel capacity to 1035 liters. These cylindrical fuel tanks were later used on Soviet main battle tanks as additional fuel tanks. Further development of the T-44 was canceled and all the attention was directed towards the development of a new T-54 main battle tank.
Tank designers recommended research on a new tank design, a medium tank capable of going 35 km/h and weighing 15 tons with offensive and defensive abilities greater than the Type 89 I-Go. The Chief-of-Staff Operations was not enthusiastic for the project as it was peace-time and the military had a limited budget. The army thus issued peace time requirements for a new tank design. Rather than focusing on performance improvements, the Chief-of-Staff Operations made a lighter weight the main requirement in order to lower production costs. The finalised requirements were for a lighter weight tank that was capable of going 35 km/h, and armed with a 57 mm main gun. The Engineering Department believed that it was highly regrettable that their efforts would be devoted solely to weight reduction, so instead, two concurrent projects were built. The first plan was for a lower-weight, low-cost medium tank that was to be made by the Osaka Army Arsenal, which would become the Chi-Ni. The second plan was contracted to Mitsubishi Heavy Industries for a higher performance medium tank, which would become the Chi-Ha.
Machine guns diverged into heavier and lighter designs. The later model water-cooled Maxim guns and its derivatives the MG 08 and the Vickers, as well as the American M1917 Browning machine gun, were all substantial weapons. The .303 Vickers, for example, weighed 33 lb (15 kg) and was mounted on a tripod that brought the total weight to 50 lb (23 kg). The heavier designs could, and in some cases did, fire for days on end, mainly in fixed defensive positions to repel infantry attacks. These machine guns were typically mounted on tripods and were water-cooled, and a well-trained crew could fire nonstop for hours, given sufficient ammunition, replacement barrels and cooling water. Carefully positioned heavy machine guns could stop an attacking force before they reached their objectives.
The Leclerc tank (French: ) is a main battle tank (MBT) built by GIAT, now Nexter of France. It was named in honour of General Philippe Leclerc de Hauteclocque, who led the French element of the drive towards Paris while in command of the Free French 2nd Armoured Division ("2e DB") in World War II. The designation AMX-56 – while very popular – is not used officially.
One of the largest individual pieces ever found was an unexploded 'Tallboy' bomb uncovered in the Sorpe Dam in 1958.
In 2011, a 1.8-tonne RAF bomb from the Second World War was uncovered in Koblenz on the bottom of the Rhine River after a prolonged drought. It caused the evacuation of 45,000 people from the city and was then called "the biggest bomb-related evacuation in Germany's post-war history". In May 2015, Some 20,000 people had to leave their homes in Cologne in order to defuse a one-tonne bomb.
There are four main parts to make tanks in the game. The "track" determines what areas of terrain the tank can cross. These included "wheels", tracks which can only cross basic terrain, such as stone, "half-tracks", tracks which can cross desert, "snow-mobiles", tracks which can cross over snow, "boats", which can cross over water, and "hover-crafts", tracks which can cross over anything without suffering the effects of the ground. Making tanks without tracks renders them immobile, similar to turrets. The "engine" determined not only how fast the tank can go, but how many weapons an individual tank can possess. Weapons weighed down a tank and made it slower, in effect a tank with a total of five engine power and three weapons would travel the same speed as a tank with a total engine power of two and no weapons. The "weapons" automatically shoots at enemies within its range. The player can place as many weapons in a tank as it has engine power, and can not exceed a fixed height limit. The player can also order tanks to attack a specific tank or area of terrain. There are over sixty weapons in-game throughout the five time periods. Finally, the radar only comes in one variety, and is needed to make the tank function.
By the mid-1930s the French Army was replacing the aging FT fleet with a mixed force of light tanks both in the Infantry and Cavalry branches, as well as medium and heavy tanks. The Infantry light tanks included the Renault R 35, which followed the FT concept quite closely with its very small size, two-man crew, and short 37 mm gun armament. It was, however, heavily armored. The R 35 was mostly used to equip the independent tank battalions, an armoured reserve allocated at army level and intended to reinforce infantry divisions in breakthrough operations. French infantry divisions normally had no organic tank component. The R 35 was exported to Poland and Romania. The cavalry had the similar Hotchkiss H 35, armed with the same 37 mm, as well as light recon tanks such as the AMR 35.
The T-44A officially entered service with the Red Army on 23 November 1944 but the production started in October. Production took place at the new Factory No. 75 (Zavod 75) in Kharkiv which used the buildings of the old KhPZ Factory No. 183 which were recaptured from Germans on 23 August 1943. To restore the factories to working order, engineers, workers, machines and tools were sent from Stalin Ural Tank Factory No. 183, located in Nizhny Tagil. The original plans were that the factory would produce 300 T-44As a month. However, only 25 were built by the end of 1944. In 1945, 940 were built, making a total of 965 (190 tanks built in 1944 and 1945 were completed by the end of the war). An additional 858 T-44As were made in 1946-1947. The T-34 continued to account for 85% of medium tank production through 1950, and development of a more advanced medium tank with a more powerful 100 mm gun proceeded. The relatively brief production run ended in 1947 with a total of 1,823 T-44A tanks built. The reasons for such a brief production run included mechanical teething problems, the end of the war which reduced the Red Army's need for a new tank, and the design's inability to successfully fit a 100 mm tank gun. It was replaced on the production lines by the T-54-1 main battle tank, which was more mechanically reliable and could mount a 100 mm gun. The superior T-54-2 would replace T-34 production at the Omsk Factory No. 183 in 1950, and the T-54/55 main battle tank series would remain in production until 1981.
In armour and firepower, French tanks were generally not inferior to their German counterparts. In one incident, a single Char B1 "Eure" was able to destroy thirteen German tanks within a few minutes in Stonne on 16 May 1940, all of them Panzer III and Panzer IV tanks. The 37mm and 20mm guns the Germans used were ineffective at penetrating the thick armour of the B1, which was able to return safely despite being hit a large number of times. Even German General Rommel was surprised at how the French tanks withstood the German tank shells and had to resort to using the German 88 artillery as antitank guns against the French tanks to knock them out. Setbacks the French military suffered were more related to strategy, tactics and organisation than technology and design. Almost 80 percent of French tanks did not have radios, since the battle doctrine employed by the French military was more a slow-paced, deliberate conformance to planned maneuvers. French tank warfare was often restricted with tanks being assigned for infantry support. Unlike Germany, which had special "Panzerwaffe" divisions, France did not separate tanks from the Infantry arm, and were unable to respond quickly to the Blitzkrieg tactics employed by the Germans, which involved rapid movement, mission-type orders and combined-arms tactics.
The S35 medium tank entered service in January 1936 with the "4e Cuirassiers". At the end of 1937 the SA 35 gun became available and deliveries of the main production series could begin. By mid 1938 a hundred had been produced, 270 on 1 September 1939 and 246 delivered. On this date 191 served with the troops, 51 were in depot and four had been sent back to the factory for overhaul. After the outbreak of war a fourth order of 200 was made, bringing the ordered total to 700. Later it was decided that from the 451st vehicle onward the tanks would be of the improved S 40 type. Production in fact totalled 430 by June 1940, including the prototype and the preseries.
SS "Great Eastern" was an iron sailing steamship designed by Isambard Kingdom Brunel, and built by J. Scott Russell & Co. at Millwall Iron Works on the River Thames, London. She was by far the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of was only surpassed in 1899 by the 17,274-gross-ton RMS "Oceanic", her gross tonnage of 18,915 was only surpassed in 1901 by the 21,035-gross-ton RMS "Celtic", and her 4,000-passenger capacity was surpassed in 1913 by the 4,935-passenger SS "Imperator". The ship's five funnels were rare. These were later reduced to four.
MBTs, like previous models of tanks, move on continuous tracks, which allow a decent level of mobility over most terrain including sand and mud. They also allow tanks to climb over most obstacles. MBTs can be made water-tight, so they can even dive into shallow water ( with snorkel). However, tracks are not as fast as wheels; the maximum speed of a tank is about ( for the Leopard 2). The extreme weight of vehicles of this type (45-70 tons) also limits their speed. They are usually equipped with a engine (more than ), with an operational range near .
British long-range bomber planes such as the Short Stirling had been designed before 1939 for strategic flights and given a large armament, but their technology still suffered from numerous flaws. The smaller and shorter ranged Bristol Blenheim, the RAF's most-used bomber, was defended by only one hydraulically operated machine-gun turret, and whilst this appeared sufficient, it was soon revealed that the turret was a pathetic defence against squadrons of German fighter planes. American bomber planes such as the B-17 Flying Fortress had been built before the war as the only adequate long-range bombers in the world, designed to patrol the long American coastlines. Defended by as many as six machine-gun turrets providing 360° cover, the B-17s were still vulnerable without fighter protection even when used in large formations.
Imperial Japanese Navy (IJN) submarines formed by far the most varied fleet of submarines of World War II, including manned torpedoes ("Kaiten"), midget submarines ("Kō-hyōteki", ), medium-range submarines, purpose-built supply submarines (many used by the Imperial Japanese Army, see Type 3), fleet submarines (many of which carried an aircraft), submarines with the highest submerged speeds of the conflict ("Sentaka" ), and submarines able to carry multiple bombers (World War II's largest submarine, the Sentoku ). They were also equipped with the most advanced torpedo of the conflict, the oxygen-fuelled Type 95 (which are sometimes confused with the famed Type 93 Long Lance torpedo).
The United States Army had always regarded the French Army as the best army in Europe, and consequently the US Army frequently copied French uniforms (the US Civil War) and aeroplanes. Only when France was rapidly overrun in 1940 did the US Army become "shocked" into re-thinking the influences by the perceived actions of German tanks in the 1939 Polish Campaign. Its Armored Combat Arm was not created until 1940 when The Armored Force was born on 10 July 1940, with the Headquarters, Armor Force and the Headquarters, I Armored Corps established at Fort Knox. On July 15, 1940, the 7th Cavalry Brigade (Mechanised) became the 1st Armored Division; the 7th Provisional Tank Brigade, an infantry tank unit at Fort Benning, became the 2nd Armored Division". The Tank Battalion was established at Fort Meade, Md., and a small Armored Force School was also established.
Jacob Stolt-Nielsen helped establish United Tank Containers in 1978, starting small with only a few units. The outfit was eventually renamed Stolt Tank Containers (STC). It currently operates the world's largest fleet of stainless steel ISO tank containers, with more than 31,000 units in service. The fleet is supported by a global network of 24 offices and 15 tank maintenance, repair and cleaning depots in locations worldwide.
In general, French tanks of the 1930s were well-armored, innovative vehicles that owed little to foreign designs. However, the light tanks lacked firepower and almost all French tanks were handicapped by their one-man turrets, even the larger tanks such as the Char B1, which overworked the commander who, besides directing the vehicle, or even a troop, had to load and aim the turret gun. The lack of radios with the light tanks was not seen as a major drawback, since French doctrine called for slow-paced, deliberate maneuvers in close conformance to plans. The role of small unit leaders was to execute plans, not to take the initiative in combat. In 1939, a belated effort was made to improve flexibility and increase the number of radios.
The Republic P-47 Thunderbolt was a World War II era fighter aircraft produced by the United States from 1941 through 1945. Its primary armament was eight .50-caliber machine guns and in the fighter-bomber ground-attack role it could carry five-inch rockets or a bomb load of 2,500 pounds (1,103 kg). When fully loaded the P-47 weighed up to eight tons (tonnes) making it one of the heaviest fighters of the war. The P-47 was designed around the powerful Pratt & Whitney R-2800 Double Wasp engine which was also used by two U.S. Navy fighters, the Grumman F6F Hellcat and the Vought F4U Corsair. The Thunderbolt was effective as a short-to-medium range escort fighter in high-altitude air-to-air combat and ground attack in both the World War II European and Pacific theaters.
The largest land mammal extant today is the African bush elephant. The largest extinct land mammal known was long considered to be "Paraceratherium orgosensis", a rhinoceros relative thought to have stood up to tall, measured over long and may have weighed about 17 tonnes. In 2015, a study suggested that one example of the proboscidean "Palaeoloxodon namadicus" may have been the largest land mammal ever, based on extensive research of fragmentary leg bone fossils from one individual, with a maximum estimated size of 22 tonnes.
Fighter-bombers became increasingly important in the 1950s and 1960s, as new jet engines dramatically improved the power of even the smallest fighter designs. Many aircraft initially designed as fighters or interceptors found themselves in the fighter-bomber role at some point in their career. Notable among these is the Lockheed F-104 Starfighter, first designed as a high-performance day fighter and then adapted to the nuclear strike role for European use. Another such aircraft was the Indian HAL HF-24 Marut. It was used during the Indo-Pak war of 1971, and only three aircraft were lost to ground fire. One aerial kill recorded by Marut flown by Squadron Leader K.K. Bakshi of 220 Squadron shot down a PAF F-86 Sabre on 7 Dec 71 (Flag Officer Hamid Khwaja of 15 Squadron PAF). Other U.S. examples include the North American F-100 Super Sabre and (perhaps most famously) the McDonnell Douglas F-4 Phantom II, each of which were widely used during the Vietnam War.
The Neoplan Jumbocruiser was an articulated double-deck multi-axle city coach built by Neoplan Bus GmbH between 1975 and 1992. At in length, wide and in height, it is in the Guinness World Records as the world's largest bus with a capacity for 170 passengers.
Two specially constructed tanks were used. The first one, based on the abandoned plant's primary reactor containment vessel, held of water, was 55 feet (18 m) deep and 209 feet (70 m) across. At the time, it was the largest fresh-water filtered tank in the world. Additional scenes were shot in the second tank, an unused turbine pit, which held of water. As the production crew rushed to finish painting the main tank, millions of gallons of water poured in and took five days to fill. The Deepcore rig was anchored to a 90-ton concrete column at the bottom of the large tank. It consisted of six partial and complete modules that took over half a year to plan and build from scratch.
The French used a very wide range of tanks, including many unique types. France was the second largest tank producer in the world, behind the Soviet Union (see French armoured fighting vehicle production during World War II). Their cavalry tank class filled the role of what are now called MBTs. They also fielded a heavy tank design, and several lighter types for scouting and infantry support. In addition to these types, they were also working on super-heavy breakthrough tanks (FCM F1). The French didn't have an independent Tank Corps. All tanks belonged to either the Infantry or the Cavalry.The Renault FT-17 had a long life and saw use in World War II and even later in Indochina. It was utilised as far away as in China, during the Chinese Civil wars, and versions of the tank were used both against and by the Japanese during the invasion of China. A large number found their way into both Republican and Nationalist hands during the Spanish Civil War. They were used in the Russian Revolution by both the Bolsheviks and the White Russians, and later by the Finns against the Soviets. France exported the FT-17 right up to World War II. The design was also developed by the Italians as the Fiat 3000 and the USSR as the T-18.
The largest single non-combat helicopter operation in history was the disaster management operation following the 1986 Chernobyl nuclear disaster. Hundreds of pilots were involved in airdrop and observation missions, making dozens of sorties a day for several months.
"Helitack" is the use of helicopters to combat wildland fires. The helicopters are used for aerial firefighting (water bombing) and may be fitted with tanks or carry helibuckets. Helibuckets, such as the Bambi bucket, are usually filled by submerging the bucket into lakes, rivers, reservoirs, or portable tanks. Tanks fitted onto helicopters are filled from a hose while the helicopter is on the ground or water is siphoned from lakes or reservoirs through a hanging snorkel as the helicopter hovers over the water source. Helitack helicopters are also used to deliver firefighters, who rappel down to inaccessible areas, and to resupply firefighters. Common firefighting helicopters include variants of the Bell 205 and the Erickson S-64 Aircrane helitanker.
The tallest and largest megalith, which lies isolated from others and has a unique Sultanate style, is believed to have been erected by the founder king of Dimapur, who after vanquishing the tribes all around made his triumpant tower to commemorate his victory and this became a tradition setter. In and around this old city, large number of tanks over fifty in number existed, although most of them have since either dried up or have been destroyed by reckless human encroachment without an iota of respect for the history. These tanks were believed to be either dug by the kings for providing water supply to their people or might have resulted due to brick making, as pieces of old bricks could still be found in and around these tanks and, as has been mentioned earlier, Dimapur was known for use of bricks. Most of large tanks are rectangular and have a hardwood seasoned poles planted deep at the centre of the tanks, which have lasted for hundreds of years. Others are of irregular shapes without any such wooden poles. Inference in that, the former ones might have been dug by the Dimasa kings for water supply and the later were habitation as Di-gojo> Dijuwa meaning cut off from main river or stream’ and this tradition is still in vogue, and this area covers Dimapur and Dimasa Kachari inhabited areas of Karbi Anglong District of Assam in the Dhansiri valley. The present Dimapur is the commercial capital of Nagaland and is one of the fastest growing townships in the entire North-east region. But irony is, in the name of the modernity and development, this ancient city of Dimapur, whose historical relics finds a place in the World. Heritage is being gradually destroyed of its rich history by reckless human greed, and total destruction of its rich heritage is only a question of time.
