MKE 120 Mm Tank Gun
The MKE 120 mm gun is a Turkish 120 mm 55 caliber smoothbore gun based on the CN08 120 mm gun produced by the Turkish company Mechanical and Chemical Industry Corporation, used on the Turkish Altay tank. The gun has a length of . The gun can fire ammunition with high muzzle velocity, and is made of chrome-plated "special steel". Background The MKE 120 mm gun was produced by transferring CN08 120 mm gun production technology from Hyundai WIA in South Korea through the Altay tank development project from 2008 to 2015. MKE modified the design per Altay requirements and produce the gun under license. The design of the tank gun is the same as CN08, but there are two differences: unlike CN08, thermal sleeve is equipped with static muzzle reference system (SMRS), and Altay's turret does not have breech opening motor and automatic feeding magazine system for autoloader mechanism, so ammunition can only be loaded manually by tank crew and can fire up to 6 rounds a minute.

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. Some examples of smoothbore weapons are muskets, blunderbusses, and flintlock pistols. The opposite of smoothbore is rifling. 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, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Reference System
A muzzle reference system (MRS) is a device used on most modern tank guns and some artillery systems that measures the bending of the barrel due to heat, gravity and other issues. It normally consists of a laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word ''laser'' originated as an acronym for light amplification by stimulated emission of radi ... device and detector mounted at the breach end of the gun, often co-located with other optics like the gunner's sight, and a mirror at the muzzle. By measuring the deflection of the barrel, corrections can be applied by the ballistic computer to correct for changes as the gun is fired.

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 co ...

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. It is also fitted with a muzzle reference system (MRS) 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 projec ...

MBT-80
The FV4601 MBT-80 was a British experimental list of main battle tanks by generation#Third, third-generation main battle tank, designed in the late 1970s to replace the Chieftain (tank), 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 tank, 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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CN120-25
The CN120-25, also simply referred to as ''Modèle G1'' (G1 model) is a French smoothbore 120mm tank gun of 52 calibers designed by the EFAB of Bourges for the export market. Description Designed by the Établissement d'Études et de Fabrication d'Armements de Bourges (EFAB), the G1 120 mm smoothbore gun has been designed to be interchangeable with the rifled 105 mm CN 105 F1 tank gun. The G1 uses semi-combustible propellant cases and has been designed to fire both French-produced ammunition and German Rheinmetall-produced ammunition. A vertical sliding breech-block is used, the barrel is chrome-plated and autofrettaged. The 120 mm smooth-bore gun G1 has been fitted to the private venture Giat Industries AMX-32, AMX-40 and the Brazilian ENGESA EE-T2 Osório main battle tanks, neither of which entered production.

Rheinmetall Rh-120
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 ...

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, Russia, Perm. Other variations include 2A46M, 2A46M-1, 2A46M-2, 2A46M-4, 2A46M-5, and Ukrainian T-84, KBA-3 and Chinese ZPT-98. The 2A46 can fire APFSDS, 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 offer ...

Fort Halstead
Fort Halstead was a research site of the Defence Science and Technology Laboratory (Dstl), an executive agency of the UK Ministry of Defence. It is situated on the crest of the Kentish North Downs, overlooking the town of Sevenoaks, southeast of London. Originally constructed in 1892 as part of a ring of fortresses around London, Fort Halstead was to be staffed by volunteers in the event of a crisis. The base became home to the Projectile Development Establishment, the Ministry of Supply and later was the headquarters of the Royal Armament Research and Development Establishment (RARDE). Design and construction Fort Halstead formed a part of the London Defence Positions, a scheme devised by Lieutenant General Sir Edward Bruce Hamley and implemented by the Secretary of State for War, Edward Stanhope, who announced the plan to Parliament in 1889. The scheme envisaged a line of entrenchments which would be dug in the event of war to protect the southern and eastern approaches t ...
