U-5TS
The U-5TS (production designation 2A20) tank gun is a 115 mm-calibre weapon that was fitted exclusively to the Soviet Union's T-62 main battle tank. It was the first smoothbore weapon designed for tanks and heralded the change in main armament from rifled cannons. History As the T-54/55 series began to replace the T-34 tanks in the Soviet Army in the 1950s it was recognised that the standard NATO tanks of the time—the Centurion and M48 Patton—had armour that could not easily be defeated by the existing ammunition for the 100 mm D10 gun that the new tanks carried. The Soviets set about designing a new "heavy" vehicle which was required to complement the tanks in an overwatch capacity and to provide greater anti-armour capability. The new vehicle, the T-62, was to be equipped with a new smoothbore design—which allows higher velocity and greater armour penetration with kinetic rounds—based on an enlargement of the 100 mm 2A19 anti-tank gun that had entered ...

T-62
The T-62 is a Soviet main battle tank that was first introduced in 1961. As a further development of the T-55 series, the T-62 retained many similar design elements of its predecessor including low profile and thick turret armour. In contrast with previous tanks, which were armed with rifled tank guns, the T-62 was the first production tank armed with a smoothbore tank gun that could fire APFSDS rounds at higher velocities. While the T-62 became the standard tank in the Soviet arsenal, it did not fully replace the T-55 in export markets due to its higher manufacturing costs and maintenance requirements compared to its predecessor. Although it was followed by later models in successor states of the Soviet Union, the T-62 remained in reserve in the former USSR and in frontline use by other countries. Design features of the T-62 became standardized in subsequent Soviet and Russian mass-produced tanks. Development history The initial requirements By the late 1950s, Soviet c ...

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 tren ...

9K118 Sheksna
The 9M117 Bastion is a Russian laser beam-riding anti-tank missile. It is used in a number of separate weapon systems, including the 9K116-1 Bastion missile system (AT-10 Stabber), 9K118 Sheksna (AT-12 Swinger), T-12 antitank gun and the 3UBK12 fired from the BMP-3. The 100 mm projectile entered service in 1981.Angelskiy, R. (2002), p. 111-115 Development The 9K112 Kobra (AT-8 Songster) was the first Soviet tube fired anti-tank missile to enter service; however, it was only deployed in limited numbers to front line units. Development work began in the late 1970s on a third generation of guided projectiles that would use laser guidance rather than radio command links. The guidance system was developed by Igor Aristarkhov, and the missile was developed by Petr Komonov. The Bastion was developed firstly as a relatively cheap missile fired from towed MT-12 100 mm smoothbore anti-tank guns. The 9M117 missile was part of the 3UBK10 round and the whole weapon system was desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a List of former transcontinental countries#Since 1700, transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a Federation, federal union of Republics of the Soviet Union, fifteen national republics; in practice, both Government of the Soviet Union, its government and Economy of the Soviet Union, its economy were highly Soviet-type economic planning, centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian Soviet Federative Socialist Republic, Russian SFSR. Other major cities included Saint Petersburg, Leningrad (Russian SFSR), Kyiv, Kiev (Ukrainian Soviet Socialist Republic, Ukrainian SSR), Minsk (Byelorussian Soviet Socialist Republic, Byelorussian SSR), Tas ...

South Ossetia War (2008)
The 2008 Russo-Georgian WarThe war is known by a variety of other names, including Five-Day War, August War and Russian invasion of Georgia. was a war between Georgia, on one side, and Russia and the Russian-backed self-proclaimed republics of South Ossetia and Abkhazia, on the other. The war took place in August following a period of worsening relations between Russia and Georgia, both formerly constituent republics of the Soviet Union. The fighting took place in the strategically important South Caucasus region. It is regarded as the first European war of the 21st century. The Republic of Georgia declared its independence in early 1991 as the Soviet Union began to fall apart. Amid this backdrop, fighting between Georgia and separatists left parts of the former South Ossetian Autonomous Oblast under the ''de facto'' control of Russian-backed but internationally unrecognised separatists. Following the war, a joint peacekeeping force of Georgian, Russian, and Ossetian troop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. 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, but it allows a longer, more streamlined round with greater sectional density to be fired from the same caliber barrel, ...

Main Battle Tank
A main battle tank (MBT), also known as a battle tank or universal tank, is a tank that fills the role of armor-protected direct fire and maneuver in many modern armies. Cold War-era development of more powerful engines, better suspension systems and lighter-weight composite armor allowed the design of a tank that had the firepower of a super-heavy tank, the armor protection of a heavy tank, and the mobility of a light tank, in a package with the weight of a medium tank. Through the 1960s and 1970s, the MBT replaced almost all other types of tanks, leaving only some specialist roles to be filled by lighter designs or other types of armored fighting vehicles. Main battle tanks are a key component of modern armies. House (1984), ''Toward Combined Arms Warfare: A Survey of 20th-Century Tactics, Doctrine, and Organization'' Modern MBTs seldom operate alone, as they are organized into armoured units that include the support of infantry, who may accompany the tanks in infant ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove mea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Russo-Ukrainian War
The Russo-Ukrainian War; uk, російсько-українська війна, rosiisko-ukrainska viina. has been ongoing between Russia (alongside Russian separatists in Ukraine) and Ukraine since February 2014. Following Ukraine's Revolution of Dignity, Russia annexed Crimea from Ukraine and supported pro-Russian separatists in the war in Donbas against Ukrainian government forces; fighting for the first eight years of the conflict also included naval incidents, cyberwarfare, and heightened political tensions. In February 2022, the conflict saw a major escalation as Russia launched a full-scale invasion of Ukraine. In early 2014, pro-Russian Ukrainian president Viktor Yanukovych was ousted from office as a result of the pro-European Euromaidan and the Revolution of Dignity. Shortly after Yanukovych's overthrow and exile to Russia, pro-Russian unrest erupted in Ukraine's eastern and southern regions. Simultaneously, unmarked Russian troops moved into Ukraine's ...
