14.5×114mm
The 14.5×114mm (.57 calibre) is a heavy machine gun and anti-materiel rifle cartridge used by the Soviet Union, the former Warsaw Pact, modern Russia, and other countries. It was originally developed for the PTRS and PTRD anti-tank rifles, and was later used as the basis for the KPV heavy machine gun that formed the basis of the ZPU series anti-aircraft guns that is also the main armament of the BTR series of armoured personnel carriers from the BTR-60 to the BTR-80 and for heavy anti-materiel sniper rifles. Cartridge dimensions The 14.5×114mm has 42.53 ml (655 grains H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions. 14.5×114mm maximum cartridge dimensions. All dimensions in millimetres (mm). Americans define the shoulder angle at alpha/2 = 22.5 degrees. The common rifling twist rate for this cartridge is 455 mm (1 i ...

PTRS
The PTRS-41 or Simonov anti-tank rifle (russian: ПротивоТанковое Ружьё Симонова) is a World War II-era semi-automatic anti-tank rifle firing the 14.5×114mm cartridge. Design The PTRS-41 was produced and used by the Soviet Union during World War II. In the years between the World Wars, the Soviet Union began experimenting with different types of armour-piercing anti-tank cartridges. Finding the 12.7×108mm insufficient, they began development of what became the 14.5×114mm armour-piercing round. Rukavishnikov developed to use this cartridge, but it was not successful because of some manufacturing issues, a sufficient number of more effective anti-tank guns in the Red Army, and high expectations about new German tank armour. In 1941, the loss of huge amounts of anti-tank artillery created a need for a stop-gap anti-tank weapon, so famous USSR weapons designers such as Vasily Degtyaryov and Sergei Gavrilovich Simonov were tasked to design anti-tank ...

Sniper Rifle
A sniper rifle is a high-precision, long-range rifle. Requirements include accuracy, reliability, mobility, concealment and optics for anti-personnel, anti-materiel and surveillance uses of the military sniper. The modern sniper rifle is a portable shoulder-fired weapon system with a choice between bolt-action or semi-automatic action, fitted with a telescopic sight for extreme accuracy and chambered for a high-ballistic performance centerfire cartridge. History The Whitworth rifle was arguably the first long-range sniper rifle in the world. Designed by Sir Joseph Whitworth, a prominent British engineer, it used barrels with hexagonal polygonal rifling, which meant that the projectile did not have to bite into the rifling grooves as was done with conventional rifling. His rifle was far more accurate than the Pattern 1853 Enfield, which had shown some weaknesses during the recent Crimean War. At trials in 1857, which tested the accuracy and range of both weapons, Whitworth's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KPV Heavy Machine Gun
The KPV-14.5 heavy machine gun (KPV is an initialism for Krupnokaliberniy Pulemyot Vladimirova (Large-caliber Machine gun Vladimirov), in Russian as Крупнокалиберный Пулемёт Владимирова, or КПВ) is a Soviet designed 14.5×114mm-caliber heavy machine gun, which first entered service as an infantry weapon (designated ''PKP'') in 1949. In the 1960s, the infantry version was taken out of production because it was too large and heavy. It was later redesigned for anti-aircraft use, because it showed excellent results as an AA gun, with a range of 3,000 meters horizontally and 2,000 meters vertically against low flying planes. It was used in the ZPU series of anti-aircraft guns. Its size and power also made it a useful light anti-armour weapon on the BTR series of vehicles and the BRDM-2 scout car. Mechanics The KPV was a heavy machine gun developed by S. V. Vladimirov. It was developed in 1944 and adopted in 1949. It combines the rate of fire of a ...

ZPU-4
The ZPU (, meaning "anti-aircraft machine gun mount") is a family of towed anti-aircraft gun based on the Soviet 14.5×114mm KPV heavy machine gun. It entered service with the Soviet Union in 1949 and is used by over 50 countries worldwide. Quadruple (ZPU-4), double- (ZPU-2 and ZU-2) and single-barreled (ZPU-1) versions of the weapon exist. Precursor The first dedicated Soviet mount for anti-aircraft machine guns was developed around 1928 by Fedor Tokarev and was adopted for service in 1931. It was a base for mounting up to four 7.62 mm PM M1910 (Russian Maxim) guns. This was also called a ZPU, although the name М-4 was also assigned to it. It served the Soviet armed forces in all major conflicts until 1945. 12.7 mm DShK 1938 was used an anti-aircraft weapon it was mounted on pintle and tripod mounts, and on a triple mount on the GAZ-AA truck. Late in the war, it was mounted on the cupolas of IS-2 tanks and ISU-152 self-propelled guns. As an infantry heavy supp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PTRD
The PTRD-41 (Shortened from Russian, ''ProtivoTankovoye Ruzhyo Degtyaryova''; ''Противотанковое однозарядное ружьё системы Дегтярёва образца 1941 года''; "Degtyaryov Single Shot Anti-Tank Weapon System Model of 1941") was an anti-tank rifle produced and used from early 1941 by the Soviet Red Army during World War II. It was a single-shot weapon which fired a 14.5×114 mm round, which was able to penetrate German tanks such as the Panzer III and early models of the Panzer IV. Although unable to penetrate the frontal armor of late-war German tanks, it could penetrate their thinner side armor at close ranges as well as thinly armored self-propelled guns and half-tracks. History In 1939, in its invasion of Poland the USSR captured several hundred Polish Model 35 anti-tank rifles, which had proved effective against the German invasion of Poland from the West. Vasily Degtyaryov copied its lock and several features of the G ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
BTR-80
The BTR-80 (russian: бронетранспортёр, bronyetransportyor, literally "armoured transporter") is an 8×8 wheeled amphibious armoured personnel carrier (APC) designed in the USSR. It was adopted in 1985 and replaced the previous vehicles, the BTR-60 and BTR-70, in the Soviet Army. It was first deployed during the Soviet–Afghan War. The BTR-80 was developed into the larger BTR-90. Description The Soviets based the BTR-80 on the BTR-70 APC, which itself was based on the BTR-60. It has a single 260-hp V-8 turbocharged water-cooled diesel engine, an improvement over the twin gasoline engines installed in the BTR-60 and BTR-70 vehicles. The reconfigured rear portion of the hull accommodates the new, single engine. The Soviets removed the roof chamfers of the modified BTR-70, raised the rear, and squared off the rearward-sloping engine compartment. Standard equipment includes TNPO vision blocks, TNP-B and TKN-3 optical devices for the driver and commander, an OU-3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heavy Machine Gun
A heavy machine gun (HMG) is significantly larger than light, medium or general-purpose machine guns. HMGs are typically too heavy to be man-portable (carried by one person) and require mounting onto a weapons platform to be operably stable or tactically mobile, have more formidable firepower, and generally require a team of personnel for operation and maintenance. There are two generally recognized classes of weapons identified as HMGs. The first are weapons from World War I identified as "heavy" due to the weight and cumbersomeness of the weapons themselves, which prevents infantrymen from transporting on foot, such as the M1917 Browning machine gun. The second are large-caliber ( 12.7×99mm, 12.7×108mm, 14.5×114mm, or larger) machine guns, pioneered by John Browning with the M2 machine gun, designed to provide increased effective range, penetration and destructive power against covers, vehicles, aircraft and light buildings/fortifications beyond the standard-caliber ...

Anti-materiel Rifle
An anti-materiel rifle (AMR) is a rifle designed for use against military equipment, structures, and other hardware (materiel). Anti-materiel rifles are chambered in significantly larger calibers than conventional rifles and are employed to eliminate equipment such as engines and unarmored or lightly armored targets. While modern armored vehicles are resistant to anti-materiel rifles, the extended range and penetration still has many modern applications. While not intended for use against human targets, the bullet weight and velocity of anti-materiel rifles gives them exceptional long-range capability even when compared with designated sniper rifles. Anti-materiel rifles are made in both bolt-action as well as semi-automatic designs. History The origins of the anti-materiel rifle go back to the First World War, during which the first anti-tank rifles appeared. While modern tanks and most other armored vehicles are too well protected to be affected by anti-materiel rifles, the gun ...

Cartridge (firearms)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile ( bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete ...

Rifling
In firearms, rifling is machining helical grooves into the internal (bore) surface of a gun's barrel for the purpose of exerting torque and thus imparting a spin to a projectile around its longitudinal axis during shooting to stabilize the projectile longitudinally by conservation of angular momentum, improving its aerodynamic stability and accuracy over smoothbore designs. Rifling is characterized by its twist rate, which indicates the distance the rifling takes to complete one full revolution, such as "1 turn in 10 inches" (1:10 inches), "1 turn in 254 mm" ("1:254 mm" or "1:25.4 cm)", or the like. Normally, an experienced shooter can infer the units of measurement from the numbers alone. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will rotate at a higher spin rate. The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it – ...
