CN120-26
The CN120-26, also simply referred to as ''Modèle F1'' (F1 model) is a French smoothbore 120mm tank gun of 52 calibers designed by the EFAB of Bourges and produced by Giat Industries . Description The 120 mm smoothbore gun F1 has been designed for installation in the Leclerc main battle tank. The smooth-bore gun is chrome-plated, fitted with a thermal sleeve and has a vertical sliding breech mechanism. II is also fitted with a muzzle reference system and the tropicalized variant of the Leclerc is fitted with a compressed air system for removing propellant fumes. In the Leclerc application, the gun is fed by a 22-rounds bustle-mounted automatic loader designed by Creusot-Loire Industries. The 120 mm F1 gun fires the same 120×570mm ammunition as the German Rh-120 and American M256 smoothbore guns. The French 120 mm F1 gun is, however, 1 m longer than the L/44 version of the Rh-120, which increases muzzle velocity and armour penetration of APFSDS projectiles; ...

IMI 120 Mm Gun
The IMI 120 mm gun is an L44 smoothbore tank gun designed and produced by Israeli Military Industries (IMI). It is widely confused as a licensed production of the Rheinmetall L44 tank gun, however it was developed by IMI from 1983 to 1988, to meet the requirements of the Israel Defense Forces' Merkava Mark III main battle tank, i.e. a narrower mount like in the M60, both tanks designed around a 105 mm gun. It was first revealed in 1989 when it was shown to be the main armament of the Merkava Mark III. In 1990 the Israel Defense Prize was awarded to Israeli Military Industries for this development, which gave Israel the means to produce tank guns independently. Design This tank gun is very similar to the Rheinmetall L44 versions installed on the German Leopard 2, American M1 Abrams, South Korean K1A1, and Japanese Type 90 main battle tanks. However, it has a different recoil system, consisting of an optimized concentric retarder and pneumatic recuperator, and more comp ...

CN08 120 Mm Gun
The CN08 is a 120 mm 55-caliber smoothbore gun produced by Hyundai WIA. It is incorrectly known as the licensed production of the Rheinmetall Rh-120 L/55, but it was indigenously developed by the Agency for Defense Development and WIA (now Hyundai WIA) from 2003 to 2008 for the XK2 development project started in 1995. The development was completed after the operational test ended in September 2008. Description The CN08 is the main armament of the K2 Black Panther, and the gun barrel is applied with internal chrome plating technology for the large-caliber gun. The gun barrel can endure a high explosive force as a result of the increased stiffness and wear resistance provided by this internal chromium surface. The main components, including the breech ring, breech block and thermal sleeve, are simplified and designed lightly, the gun barrel weighs 1324 kg and the gun mount weighs 3103 kg. The gun mount consists of a hydro-pneumatic recoil system and is complemented by a bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2A46 125 Mm Gun
The 2A46 (also called D-81TM) is a 125 mm/L48 smoothbore cannon of Soviet origin used in several main battle tanks. It was designed by OKB-9 (Artillery Plant No. 9) in Yekaterinburg. Description It was developed by the Spetstekhnika Design Bureau in Ekaterinburg in the 1960s originally for the T-64 tank. They were subsequently manufactured at Artillery Plant No. 9 in Ekaterinburg and Motovilikha in Perm. Other variations include 2A46M, 2A46M-1, 2A46M-2, 2A46M-4, 2A46M-5, and Ukrainian KBA-3 and Chinese ZPT-98. The 2A46 can fire armour-piercing fin-stabilised discarding sabot (APFSDS), high-explosive anti-tank (HEAT) and high-explosive fragmentation (HEF) projectiles. The ammunition for the 2A46 gun is in two pieces: the projectile is loaded first, followed by a separate propellant charge. The early versions of the 2A46 suffered from a relatively short barrel life, but this was rectified on the 2A46M-1 version. Depending on the version it offers or from the 2A46M-1 ...

Rheinmetall Rh-120
The Rheinmetall Rh-120 is a 120 mm smoothbore tank gun designed and produced in former West Germany by the Rheinmetal-DeTec AG 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 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 and mount. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Ordnance L30
The L30A1, officially designated Gun 120 mm Tk L30, is a 120 mm rifled tank gun used by the British Army and Royal Army of Oman. It is an improved production model of the Royal Ordnance L11 series of rifled tank guns. It is fitted in the turret of the Challenger 2 main battle tank, and has been retrofitted to the Challenger 1 tank. Challenger Armament The Challenger Armament (CHARM) project was intended to provide a new main armament for the Challenger 2 tank and to be retro-fitted to the Challenger 1. It involved three components: the gun, developed by the Royal Ordnance Factory, Nottingham, the depleted uranium (DU) APFSDS round, and a propellant charge for it. After earlier projects were cancelled, the EXP 32M1 experimental gun was re-titled the XL30E4 and accepted for production as the L30 in 1989. The Challenger 2 tank was first produced in 1993. Design The barrel is 55 calibres long (L55) and is made of electro-slag refined steel. The bore and chamber are el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Ordnance L11
The Royal Ordnance L11A5, officially designated Gun 120 mm Tk L11, is a 120 mm L/55 rifled tank gun design. It was the first of NATO's 120 mm main battle tank guns which became the standard calibre for Western tanks in the later period of the Cold War. By 2005, a total of 3,012 L11 guns were produced. List price was US $227,000 (1990). The L11 was developed by Britain's Royal Ordnance Factories to equip the Chieftain tank as the successor to the 105 mm L7 gun used in the Centurion tank. It was also used on the Challenger 1, which replaced the Chieftain in British and Jordanian service. The weapon has been superseded by the L30 series 120 mm rifled tank gun. History The Royal Armament Research and Development Establishment at Fort Halstead designed a new 120 mm rifled tank gun in 1957. The new gun was deemed to be necessary because the British Army specified engagement ranges greater than those of other armies, for example , as specified by the U ...

Leclerc Tank
The Leclerc is a third generation French main battle tank developed and manufactured by Nexter Systems. It was named in honor of Marshal Philippe Leclerc de Hauteclocque, a commander of the Free French Forces, who led the 2nd Armoured Division in World War II. The Leclerc is in service with the French Army, Jordanian Army and the United Arab Emirates Army. In production since 1991, the Leclerc entered French service in 1992, replacing the AMX 30 as the country's main armoured platform. With production now complete, the French Army operates 222 Leclercs (with 184 more in storage for a total of 406), while the United Arab Emirates Army possesses 388. Of the units in French service, 200 will be upgraded to the XLR standard with deliveries expected to begin in 2022. History In 1964, studies were initiated about a possible replacement vehicle for the AMX-30 main battle tank: the ''Engin Principal Prospectif''. In 1971, in view of the inferiority of the AMX 30 in comparison to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
120×570mm NATO
120×570mm NATO tank ammunition (4.7 inch) also known as 120×570R is a common, NATO-standard (STANAG 4385), tank gun semi-combustible cartridge used by 120mm smoothbore guns, superseding the earlier 105×617mmR cartridge used in NATO-standard rifled tank guns. History The 120×570R cartridge was originally intended for the German Rh-120 smoothbore gun but an interoperability agreement signed between West Germany and France in April1979, followed in September1981 by a project to install the M256 120 mm smoothbore gun on future M1A1 Abrams tanks made it a NATO standard. Characteristics The 120×570mm are one-piece ammunition with semi-combustible cartridge cases. These incorporate a short, metallic stub case with an elastomeric sealing ring which allows the use of a normal sliding wedge type of breech and at the same time significantly reduces the weight of the rounds. Thus, a round of 120 mm Rheinmetall APFSDS ammunition has a mass of 19.8 kg, which is littl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rheinmetall

MBT-80
The FV4601 MBT-80 was a British experimental third-generation main battle tank, designed in the late 1970s to replace the Chieftain tank. It was eventually (and later controversially) cancelled in favour of the Challenger 1, itself an evolution of the Chieftain design. History By the early 1970s, there was a great disparity in the number of tanks being fielded by NATO and the Warsaw Pact in Europe. The US Army fielded the M60 which had been designed to deal with the 100 mm gun of the T-55, but could not withstand the 115 mm gun being fielded on the T-62, let alone the newer 125 mm model of the T-64 and T-72. The same-era West German design, the Leopard 1, was very lightly armoured based on the conclusion that heavy armour had little purpose in an era of high-explosive anti-tank (HEAT) weapons of rapidly improving performance. The concept was to give the tank high manoeuvrability to allow it to outmanoeuvre the slower-moving Soviet tanks and early generation mis ...

Smoothbore
A smoothbore weapon is one that has a barrel without rifling. Smoothbores range from handheld firearms to powerful tank guns and large artillery mortars. History Early firearms had smoothly bored barrels that fired projectiles without significant spin. To minimize inaccuracy-inducing tumbling during flight, their projectiles required an aerodynamically uniform shape, such as a sphere. However, surface imperfections on the projectile and/or the barrel will cause even a sphere to rotate randomly during flight, and the Magnus effect will curve it off the intended trajectory when spinning on any axis not parallel to the direction of travel. Rifling the bore surface with spiral grooves or polygonal valleys imparts a stabilizing gyroscopic spin to a projectile that prevents tumbling in flight. Not only does this more than counter Magnus-induced drift, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, improvi ...
