Rheinmetall 120 Mm Gun
The Rheinmetall Rh-120 is a 120 mm smoothbore tank gun designed and produced in former West Germany by the Rheinmetall Waffe Munition GmbH company. It was developed in response to Soviet advances in armour technology and development of new armoured threats. Production began in 1974, with the first version of the gun, known as the ''L/44'' as it was 44 calibres long, used on the German Leopard 2 tank and soon produced under license for the American M1A1 Abrams and other tanks. The L/44 gun has a length of , and the gun system weighs approximately . By 1990, the L/44 was not considered powerful enough to defeat future Soviet armour, which stimulated an effort by Rheinmetall to develop a better main armament. This first involved a tank gun named ''Neue Panzerkanone 140'' ('new tank gun 140'), but later turned into a compromise which led to the development of an advanced 120 mm gun, the L/55, based on the same internal geometry as the L/44 and installed in the same breech ...

M256 (tank Gun)
The M256 is an American 120 mm smoothbore tank gun. It is a licensed-built German-designed Rheinmetall Rh-120 L44 gun tube and combustible cartridges with an American-designed mount, cradle and recoil mechanism. It is primarily used by the M1 Abrams main battle tank. Origins A number of considerations had led the U.S. Army and its contractors to favor the Army's standard M68 105 mm gun over Germany's 120 mm Rheinmetall Rh-120 smoothbore gun for the XM1 Abrams. To begin with, the 105 mm gun was "the smallest, lightest, and least costly gun adequate for the job."This is the testimony of Brigadier General Philip L. Bolte, Deputy Commanding General of the U.S. Army's Testing and Evaluation Command, before the Investigations Subcommittee of the House Committee on Armed Services in April 1978; ''Army Reprogramming Request No. 78-14 P/A, FRG Smooth Bore 120-MM Gun and XM-1 Tank'', 95th Cong., 2d Sess., p. 30.

Challenger 2
The FV4034 Challenger 2 (MoD designation "CR2") is a third generation British main battle tank (MBT) in service with the armies of the United Kingdom, Oman, and Ukraine. It was designed by Vickers Defence Systems (now Rheinmetall BAE Systems Land (RBSL)) as a private venture in 1986, and was an extensive redesign of the company's earlier Challenger 1 tank. The Ministry of Defence ordered a prototype in December 1988. The Challenger 2 has four crew members consisting of a commander, gunner, loader, and driver. The main armament is a L30A1 rifled tank gun, an improved derivative of the L11 gun used on the Chieftain and Challenger 1. Fifty rounds of ammunition are carried for the main armament, alongside 4,200 rounds of 7.62 mm ammunition for the tank's secondary weapons: a L94A1 EX-34 chain gun mounted coaxially, and a L37A2 (GPMG) machine gun. The turret and hull are protected with second generation Chobham armour, also known as Dorchester. Powered by a Perkins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1982 Lebanon War
The 1982 Lebanon War, also called the Second Israeli invasion of Lebanon, began on 6 June 1982, when Israel invaded southern Lebanon. The invasion followed a series of attacks and counter-attacks between the Palestine Liberation Organization (PLO) operating in southern Lebanon and the Israel Defense Forces, Israeli military, which had caused civilian casualties on both sides of the border. The Israeli military operation, codenamed Operation Peace for Galilee, was launched after gunmen from the Abu Nidal Organization attempted to assassinate Shlomo Argov, Israel's ambassador to the United Kingdom. Israeli Prime Minister Menachem Begin blamed the PLO, using the incident as a ''casus belli''. It was the second invasion of Lebanon by Israel, following the 1978 South Lebanon conflict. The Israelis sought to end Palestinian insurgency in South Lebanon, Palestinian attacks from Lebanon, destroy the Palestine Liberation Organization (PLO) in the country, and install a pro-Israel Leban ...

T-72
The T-72 is a family of Soviet Union, Soviet main battle tanks that entered production in 1973. The T-72 was a development based on the T-64 using thought and design of the previous Object 167M. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The Russian T-90 introduced in 1992 and the Chinese Type 99 tank, Type 99 are further developments of the T-72. Production and development of various modernized T-72 models continues today. Development Development from the T-64 The T-72 was a product of a rivalry between design teams. Kharkiv Morozov Machine Building Design Bureau, Morozov KB was led by Alexander Alexandrovich Morozov, Alexander Morozov in Kharkiv. Uralvagonzavod, Uralvagon KB was led by Leonid Kartsev in Nizhny Tagil. To improve on the T-62, two designs based on the tank were tested in 1964: Nizhny Tagil's Object 167 (T- ...

Uralvagonzavod
UralVagonZavod () is a Russian machine-building company located in Nizhny Tagil, Russia. It is one of the largest scientific and industrial complexes in Russia and the largest main battle tank manufacturer in the world. Etymology The name ''Уралвагонзавод'' means ''Ural Railroad Car (wagon) Factory''. History The plant was built during 1931–1936, mostly during the second Five-year plans of the Soviet Union, Soviet five-year plan. It opened on October 11, 1936, and was named after Felix Dzerzhinsky. Initially it manufactured freight cars. After the Operation Barbarossa, German invasion of 1941, Joseph Stalin ordered hundreds of factories in Ukraine and western Russia to be evacuated east. The KhPZ Factory No. 183 in Kharkiv was moved to Nizhny Tagil by rail, and merged with the Dzerzhinsky Works, to form the Stalin Ural Tank Factory No. 183. During the Second World War it became the largest producer of tanks in the world, including the T-34. For its services, U ...

T-64
The T-64 is a Soviet tank manufactured in Kharkiv, and designed by Alexander Morozov. The tank was introduced in the early 1960s. It was a more advanced counterpart to the T-62: the T-64 served in tank divisions, while the T-62 supported infantry in motor rifle divisions. It introduced advanced features including composite armour, a compact engine and transmission, and a smoothbore 125-mm gun equipped with an autoloader to allow the crew to be reduced to three so the tank could be smaller and lighter. In spite of being armed and armoured like a heavy tank, the T-64 weighed only . These features made the T-64 expensive to build, significantly more so than previous generations of Soviet tanks. This was especially true of the power plant, which was time-consuming to build and cost twice as much as more conventional designs. Several proposals were made to improve the T-64 with new engines, but chief designer Alexander Alexandrovich Morozov's political power in Moscow kept t ...

M60 Patton
The M60 is an American List of main battle tanks by generation#Second, second-generation main battle tank (MBT). It was officially standardized as the Tank, Combat, Full Tracked: 105-mm Gun, M60 in March 1959. Although developed from the M48 Patton, the M60 tank series was never officially christened as a Patton tank. It has been called a "product-improved descendant" of the Patton tank's design. The design similarities are evident comparing the original version of the M60 and the M48A2. The United States fully committed to the MBT doctrine in 1963, when the United States Marine Corps, Marine Corps retired the last (M103 (heavy tank), M103) heavy tank battalion. The M60 tank series became the American primary main battle tank during the Cold War, reaching a production total of 15,000 M60s. Hull production ended in 1983, but 5,400 older models were converted to the M60A3 variant ending in 1990. The M60 reached operational capability upon fielding to US Army European units beginni ...

T-62
The T-62 is a Soviet main battle tank that was first introduced in 1961. As a further development of the T-55 series, the T-62 retained many similar design elements of its predecessor including low profile and thick turret armour. In contrast with previous tanks, which were armed with rifled tank guns, the T-62 was the first production tank armed with a smoothbore tank gun which could fire APFSDS rounds at higher velocities (the U.S. prototype T95 medium tank was the first tank ever built with a smoothbore gun). While the T-62 became the standard tank in the Soviet arsenal, it did not fully replace the T-55 in export markets due to its higher manufacturing costs and maintenance requirements compared to its predecessor. Although it was followed by later models in successor states of the Soviet Union, the T-62 remains in reserve in some countries formerly part of the USSR and in frontline use by other countries. Design features of the T-62 became standardized in subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

T-54/T-55
The T-54 and T-55 tanks are a series of Soviet Union, Soviet medium tanks introduced in the years following the World War II, Second World War. The first T-54 prototype was completed at Nizhny Tagil by the end of 1945.Steven Zaloga, T-54 and T-55 Main Battle Tanks 1944–2004, p. 6 From the late 1950s, the T-54 eventually became the main tank for armoured units of the Soviet Army, armies of the Warsaw Pact countries, and many others. T-54s and T-55s have been involved in many of the world's armed conflicts since their introduction in the second half of the 20th century. The T-54/55 series is the most-produced tank in history. Estimated production numbers for the series range from 96,500 to 100,000. They were replaced by the T-62, T-64, T-72, T-80 and T-90 tanks in Soviet and Russian Ground Forces, Russian armies, but are still used by up to 50 other armies worldwide, some having received sophisticated retrofitting.

High-explosive Anti-tank
High-explosive anti-tank (HEAT) is the effect of a shaped charge explosive that uses the Munroe effect to penetrate heavy armor. The warhead functions by having an explosive charge collapse a metal liner inside the warhead into a high-velocity shaped charge jet; this is capable of penetrating armor steel to a depth of seven or more times the diameter of the charge (charge diameters, CD). The shaped charge jet armor penetration effect is purely kinetic in nature; the round has no explosive or incendiary effect on the armor. Unlike standard armor piercing shell, armor-piercing rounds, a HEAT warhead's penetration performance is unaffected by the projectile's velocity, allowing them to be fired by lower-powered weapons that generate less recoil. The performance of HEAT weapons has nothing to do with heat, thermal effects, with HEAT being simply an acronym. History HEAT warheads were developed during World War II, from extensive research and development into shaped charge warh ...
