The '''115 mm U-5TS''' is a Soviet tank cannon utilized for the [[T-62]] tank series. The weapon is characterized as having a smoothbore barrel and a two-plane stabilizer. Upon its introduction with the T-62 in [[Update 1.61 "Road to Glory"]], the U-5TS was the first smoothbore barrel tank cannon put into the game.

History

In 1952, there were considerations among the Soviet tank development bureaus to begin developing a new tank to replace the T-54 in Soviet service. This was finalized in 09 September 1952 in Resolution No.4169-1631 for the development of the "New Medium Tank".[1] The development focus lay in a new 100 mm D-54T gun developed by F.F. Petrov. Though attempts were made to fit the D-54T tank gun into the T-54 chassis, the gun's ammunition proved too large to be easily loaded within the turret.

The tank development project would be contested between Leonid N. Kartsev's project "Object 140" from Nizhny Tagil and Alexandr A Morozov's project "Object 430" from Kharkov. Kartsev's design would be cancelled in favor of Object 430, but continued development with a tank to use as many T-54/55 components and a larger turret culminated into the "Object 165". During this development, reports of a 100 mm T-12 smoothbore anti-tank gun showed the effectiveness of a smoothbore design. Kartsev consulted with F.F. Petrov on the feasibility of modifying the 100 mm D-54T into a smoothbore weapon. Upon finding the modification feasible without compromising the gun barrel's integrity, the 100 mm bored out into a 115 mm smoothbore gun. The weapon would be designated 115 mm U-5TS under the project name "Molot" for "Hammer".[2]

The 115 mm U-5TS would have the accolade of being the first smoothbore tank gun in production in the world, which was then followed up with the first development of an armour-piercing fin-stabilized discarding-sabot (APFSDS) round. The benefits of smoothbore over the rifled D-54T design was apparent with an increased muzzle velocity, and therefore armour penetration, using the same amount of propellant. Kartsev would install this in his Object 165 tank, which would become known as "Object 166" with the 115 mm gun installed. While the 115 mm continued to remained in testing as the Object 166 continued to be evaluated, the process was soon expedited upon the Soviet discovery of 105 mm tank guns in NATO inventory in 1961 (namely the L7 gun equipped in new American, German, and British tanks). The commander of the Soviet Grounds Forces, Vasily Ya. Chukov, was furious upon learning about this event and insisted the 115 mm must be put into service as soon as possible. As such, on 12 August 1961 with Resolution No. 729-305, the T-62 medium tank and attached 115 mm U-5TS (GAU designation 2A20) was accepted into Soviet service.[3]
