D-56T
The 76.2 mm D-56T series rifled tank gun is the tank gun used on the PT-76, which is the only known armoured vehicle to carry it. Description The D-56T is an anti-tank gun of 76.2mm calibre. It can fire five types of rounds, using a manual loader system, it has an effective fire rate of six to eight rounds per minute. It has a max effective range of approximately 1500 meters. This gun is 42 calibers long. A typical combat ammunition load consists of 24 x OF-350 Frag-HE, 4 x sub-caliber AP-T, 4 x AP-T and 8 x BK-350M HEAT rounds. The gun is usually mounted in an oval dish-type circular truncated cone turret with flat sloping sides which is mounted over the second, third, and fourth pair of road wheels. All PT-76s have a fume extractor for the main gun at the rear of the turret. Some were fitted with a multi-slotted muzzle brake. Most PT-76s typically feature this gun with a double-baffle muzzle brake, except the PT-76B, which is typically fitted with the D-56T gun with a t ...

Pt-76 Afv
The PT-76 is a Soviet Union, Soviet amphibious vehicle, amphibious light tank that was introduced in the early 1950s and soon became the standard reconnaissance tank of the Soviet Army and the other Warsaw Pact armed forces. It was widely exported to other friendly states, like India, Iraq, Syria, North Korea and North Vietnam. The tank's full name is Floating Tank–76 (, ''plavayushchiy tank'', or ). ''76'' stands for the caliber of the main armament: the 76.2 mm D-56T series rifled tank gun. The PT-76 is used in the reconnaissance and fire-support roles. Its chassis served as the basis for a number of other vehicle designs, many of them amphibious, including the BTR-50 armored personnel carrier, the ZSU-23-4 self-propelled antiaircraft gun, the ASU-85 airborne self-propelled gun and the 2K12 Kub anti-aircraft missile launch vehicle. Development After World War II, the concept of light tanks was resurrected in the USSR. They were to be used in reconnaissance units and ther ...

Tank Gun
A tank gun is the main armament of a tank. Modern tank guns are high-velocity, large-caliber artilleries capable of firing kinetic energy penetrators, high-explosive anti-tank, and cannon-launched guided projectiles. Anti-aircraft guns can also be mounted to tanks. As the tank's primary armament, they are almost always employed in a direct fire mode to defeat a variety of ground targets at all ranges, including dug-in infantry, lightly armored vehicles, and especially other heavily armored tanks. They must provide accuracy, range, penetration, and rapid fire in a package that is as compact and lightweight as possible, to allow mounting in the cramped confines of an armored gun turret. Tank guns generally use self-contained ammunition, allowing rapid loading (or use of an autoloader). They often display a bulge in the barrel, which is a bore evacuator, or a device on the muzzle, which is a muzzle brake. History World War I The first tanks were used to break through trench def ...

Armoured Fighting Vehicle
An armoured fighting vehicle (AFV) is an armed combat vehicle protected by armour, generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked. Examples of AFVs are tanks, armoured cars, assault guns, self-propelled guns, infantry fighting vehicles, and armoured personnel carriers. Armoured fighting vehicles are classified according to their characteristics and intended role on the battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are often adapted to a wide variety of applications. For example, the MOWAG Piranha, originally designed as an APC, has been adapted to fill numerous roles such as a mortar carrier, infantry fighting vehicle, and ...

Caliber (artillery)
In artillery, caliber or calibredifference in British English and American English spelling is the internal diameter of a gun barrel, or - by extension - a relative measure of the barrel length. Rifled barrels Rifled barrels introduce ambiguity to measurement of caliber. A rifled bore consists of alternating grooves and lands. The distance across the bore from groove to groove is greater than the distance from land to land. Projectiles fired from rifled barrels must be of the full groove to groove diameter to be effectively rotated by the rifling, but the caliber has sometimes been specified as the land to land diameter before rifling grooves were cut. The depth of rifling grooves (and the consequent ambiguity) increases in larger calibers. Steel artillery projectiles may have a forward bourrelet section machined to a diameter slightly smaller than the original land to land dimension of the barrel and a copper driving band somewhat larger than the groove to groove diameter t ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fume Extractor
A bore evacuator or fume extractor is a device which removes lingering gases and airborne residues from the barrel of an armored fighting vehicle's gun after firing, particularly in tanks and self-propelled guns. By creating a pressure differential in the barrel after the shell leaves, the bore evacuator causes most of the propellant gases and combustion residues to exit via the muzzle. Thus, when the breech opens for reloading, those gases and residues do not escape into the crew compartment and pose a hazard to the gun crew. Description The evacuator is a passive device generally consisting of a ring of holes drilled into the barrel, surrounded by a cylindrical pressure reservoir that is sealed to the barrel's surface. When the gun is fired, high pressure gas generated by the burning propellant pushes the projectile forward. When the projectile passes the holes drilled into the barrel the propellant gasses are free to flow into the reservoir. When the projectile leaves the ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral to the construction of, the muzzle or barrel of a firearm or cannon that is intended to redirect a portion of propellant gases to counter recoil and unwanted muzzle rise. Barrels with an integral muzzle brake are often said to be ported. The concept of a muzzle brake was first introduced for artillery. It was a common feature on many anti-tank guns, especially those mounted on tanks, in order to reduce the area needed to take up the strokes of recoil and kickback. They have been used in various forms for rifles and pistols to help control recoil and the rising of the barrel that normally occurs after firing. They are used on pistols for practical pistol competitions, and are usually called compensators in this context.STI article on Limcat Under ...

Gun Stabilizer
A gun stabilizer is a device that facilitates aiming an artillery piece by compensating for the motion of the platform on which it is mounted. For naval applications see ship gun fire-control system. Moving land-based systems tend to require more specialized stabilization. Due to the need to fire while in motion, tanks in World War II made some use of stabilization, but it became commonplace in later decades such as the cold war period. History The gunner of the early Matilda II tank elevated and depressed the gun by hand, and had a shoulder pad by which he could support it steadily as the tank moved while he stood. The primary armament of most US tanks was stabilized in elevation starting with the M3A1 Light Tank and the M3 Medium tank in November 1941. Except for the 105mm-equipped M4 Sherman tanks, all U.S.-built tanks had a stabilization system for gun elevation usable at low speeds.Page 60, SHERMAN: A History of the American Medium Tank, 1978.

Tank Guns Of The Soviet Union
A tank is an armoured fighting vehicle intended as a primary offensive weapon in front-line ground combat. Tank designs are a balance of heavy firepower, strong vehicle armour, armour, and good battlefield mobility (military), mobility provided by continuous track, tracks and a powerful engine; usually their main armament is mounted in a Gun turret, turret. They are a mainstay of modern 20th and 21st century ground forces and a key part of combined arms combat. Modern tanks are versatile mobile land weapons platforms whose main armament is a large-caliber tank gun mounted in a rotating gun turret, supplemented by machine guns or other ranged weapons such as anti-tank guided missiles or rocket launchers. They have heavy vehicle armour which provides protection for the crew, the vehicle's munition storage, fuel tank and propulsion systems. The use of tracks rather than wheels provides improved operational mobility which allows the tank to overcome rugged terrain and adverse co ...
