M829 (munition)
The M829 is an American armor-piercing, fin-stabilized, discarding sabot (APFSDS) tank round. Modeling was designed at the Ballistic Research Laboratory (BRL) at Aberdeen Proving Ground (APG), which was incorporated into the Army Research Laboratory (ARL) in 1992. The round is specifically modeled for the 120 mm M256 main gun on the Abrams M1A1 and M1A2 main battle tanks. The penetrator is carried by a sabot during its acceleration in the gun barrel. Variants M829 The M829 has a ballistic nose and five tail fins made of aluminum. It is carried in the gun tube by a three-piece aluminum sabot, which separates into three "petals" soon after the round leaves the gun tube. The propulsion system uses an obturating case base with a semi-combustible cartridge wall. It has a total weight of and utilizes a DU penetrator with a rod diameter, which will reach a muzzle velocity of using of JA-2 propellant. Maximum effective range is .

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 Pma ...

Propellant
A propellant (or propellent) is a mass that is expelled or expanded in such a way as to create a thrust or other motive force in accordance with Newton's third law of motion, and "propel" a vehicle, projectile, or fluid payload. In vehicles, the engine that expels the propellant is called a reaction engine. Although technically a propellant is the reaction mass used to create thrust, the term "propellant" is often used to describe a substance which is contains both the reaction mass and the fuel that holds the energy used to accelerate the reaction mass. For example, the term "propellant" is often used in chemical rocket design to describe a combined fuel/propellant, although the propellants should not be confused with the fuel that is used by an engine to produce the energy that expels the propellant. Even though the byproducts of substances used as fuel are also often used as a reaction mass to create the thrust, such as with a chemical rocket engine, propellant and fuel are two ...

International Traffic In Arms Regulations
International Traffic in Arms Regulations (ITAR) is a United States regulatory regime to restrict and control the export of defense and military related Military technology, technologies to safeguard National security of the United States, U.S. national security and further Foreign policy of the United States, U.S. foreign policy objectives. Overview The Federal government of the United States, United States government has put two types of regulations in place to control exports of military-relevant items: ITAR, which cover weapons and defense articles specifically (such as Missile, missiles); and the Export Administration Regulations, which cover items that may have uses in defense articles (such as a radar component used in a certain missile). The U.S. government has to give specific permission for equipment (and information, referred to in ITAR as ''technical data'') before those items can be handed over to a non-US citizen, company, or government.

Reactive Armour
Reactive armour is a type of vehicle armour that reacts in some way to the impact of a weapon to reduce the damage done to the vehicle being protected. It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators. The most common type is ''explosive reactive armour'' (ERA), but variants include ''self-limiting explosive reactive armour'' (SLERA), ''non-energetic reactive armour'' (NERA), ''non-explosive reactive armour'' (NxRA), and electric armour. NERA and NxRA modules can withstand multiple hits, unlike ERA and SLERA. A second hit in exactly the same location may potentially penetrate any of those, as the armour in that spot is compromised. Reactive armour is intended to counteract anti-tank munitions that work by piercing the armour and then either kill the crew inside, disable vital mechanical systems, or create spalling that disables the crew — or all three. Reactive armour can be defeated with multiple hits in the same pla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kontakt-5
Kontakt-5 is a type of second-generation explosive reactive armour (ERA) originating in the Soviet Union. It is the first type of ERA that is able to significantly decrease the penetration of armour-piercing fin-stabilized discarding sabot (APFSDS) rounds. Description Introduced on the T-80U tank in 1985, Kontakt-5 is made up of "bricks" of explosive sandwiched between two metal plates. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. This will force an incoming kinetic energy penetrator or shaped charge jet to cut through more armour than the thickness of the plating itself, since "new" plating is constantly fed into the penetrating body. A kinetic energy penetrator will also be subjected to powerful sideways forces, which might be large enough to cut the rod into two or more pieces. This will significantly reduce the penetrating capabilities of the penetrator, since the penetrating force will be dissipated over a larger volume of a ...

Depleted Uranium
Depleted uranium (DU; also referred to in the past as Q-metal, depletalloy or D-38) is uranium with a lower content of the fissile isotope than natural uranium.: "Depleted uranium possesses only 60% of the radioactivity of natural uranium, having been 'depleted' of much of its most highly radioactive U234 and U235 isotopes." Natural uranium contains about , while the DU used by the U.S. Department of Defense contains or less. The less radioactive and non-fissile constitutes the main component of depleted uranium. Uses of DU take advantage of its very high density of ( denser than lead). Civilian uses include counterweights in aircraft, radiation shielding in medical radiation therapy and industrial radiography equipment, and containers for transporting radioactive materials. Military uses include armor plating and armor-piercing projectiles. Most depleted uranium arises as a by-product of the production of enriched uranium for use as fuel in nuclear reactors and in the ...

120mm M829A2 APFSDS-T
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-72
The T-72 is a family of Soviet/Russian main battle tanks that entered production in 1969. The T-72 was a development of the T-64, which was troubled by high costs and its reliance on immature developmental technology. 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 T-90 introduced in 1992 is a development of the T-72B; 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. Morozov KB was led by Alexander Morozov in Kharkiv. 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-62B) and Kharkiv's Object 434. Ob. 434 was a technically ambitious prototype. Under the direction of Morozov in Kharkiv, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
