ASCALON (tank Gun)
The ''Autoloaded and SCALable Outperforming guN'' or ASCALON is a French smoothbore 140 mm tank gun of 50 calibers designed by Nexter. This gun is currently mounted on the latest prototype of the EMBT, the Leclerc Evolution prototype and is proposed for the MGCS project. History ASCALON origins date back to the FTMA (Future Tank Main Armament) NATO programme, a joint venture formed in 1988 by then GIAT Industries, Royal Ordnance Factories and Rheinmetall. The Watervliet Arsenal joined them in 1997 and the joint venture was renamed the RGR Armament GmbH group. The outcome of this collaboration was the creation of the NATO-standard 140 mm two-piece ammunition designed to succeed the 120×570mm NATO. The French, for their part, funded the construction of a lengthened Leclerc turret armed with a 140 mm smoothbore gun. The T4 turret was unveiled in 1996. In September 2016, the T4 turret was mounted on a former Leclerc MARS recovery vehicle and christened with the nam ...

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, ...

Muzzle Brake
A muzzle brake or recoil compensator is a device connected to, or a feature integral (ported barrel) 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

Thermal Sleeve
A thermal sleeve, or blanket, is a device around the length of a gun barrel of a large caliber gun, typically found on modern tanks. Its primary purpose is to provide a more consistent temperature to the gun barrel, preventing distortions due to differential thermal expansion caused by the temperature differences around the barrel when firing. Thermal sleeves were originally simply insulators. They would prevent ambient conditions such as bright sunlight or winds from heating or cooling one side of a barrel more than the other, which would cause a thermal distortion (bending or drooping), reducing accuracy. More modern variants contain concentric inner and outer insulating sleeves with a gap in between. Versions have been created which are detachable from a given barrel so that they can be re-used with a replacement barrel. Proposals exist for types that have advanced external thermal and radar profiles, reducing their thermal and radar signatures in order to make the barrel and ...

Telescoped Ammunition
Telescoped ammunition is an ammunition design in which the projectile is partially or completely enveloped by the propellant. Examples include ammunition for both hand weapons and artillery. caseless ammunition, Caseless ammunition is often telescoped. Telescoped ammunition has advantages in comparison with traditional ammunition Cartridge (firearms), cartridges. They can have reduced overall length with similar ballistics to a traditional round of comparable mass. Also, they may avoid the risk of damage to the projectile during the loading process, and may simplify and increase the reliability of magazines and other feed mechanisms. The Rikhter R-23 autocannon was chambered in the 23x260 mm telescoped round. It took some time to develop as it remained a military secret for a long time, and was not used operationally until 1964. It was used only in the tail turret of the Tu-22, and experimentally on the Salyut 3 space station. A modified version of the weapon was the only ...

Standardization Agreement
In NATO, a standardization agreement (STANAG, redundant acronym, redundantly: STANAG agreement) defines processes, procedures, terms, and conditions for common military or technical procedures or equipment between the member countries of the alliance. Each NATO state ratifies a STANAG and implements it within its own military. The purpose is to provide common operational and administrative procedures and logistics, so one member nation's military may use the stores and support of another member's military. STANAGs also form the basis for technical interoperability between a wide variety of communication and information systems (CIS) essential for NATO and Allied operations. The Allied Data Publication 34 (ADatP-34) NATO Interoperability Standards and Profiles which is covered by STANAG 5524, maintains a catalogue of relevant Information and communications technology, information and communication technology standards. STANAGs are published in English language, English and French ...

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 d ...
