In the 1960s, as the [[U-5TS (115 mm)|115 mm U-5TS]] was beginning to see service in the [[T-62]] tank to counter the newest NATO tanks such as the American [[M60]] and British [[Chieftain Mk 3|Chieftain]] tanks, Alexandr Morozov's design bureau at the Kharkov Malyshev tank plant was ordered to integrate the 115 mm cannon into their new tank program, known at the time as Object 430. The integration of the 115 cannon, modified to utilize two-piece ammunition to fit within the Object 430 design, was designated the ''115 mm D-68'' gun, or GAU designation ''2A21'' (the tank itself was designated Object 432 with this 115 mm cannon).<ref name="Zaloga_T-64(1)">Zaloga 2015, Refining the Design: Obiekt 432</ref> Despite this upgrade, Morozov's team decided the 115 mm was not lethal enough to engage the NATO tanks outside of their threat envelope, with also the fear that the 115 mm D-68 was not sufficient against the Chieftain particularly.<ref name="Fofanov">Fofanov n.d.</ref> Morozov looked into options for a stronger armament for their tank, which would be adopted as the T-64 with the 115 mm D-68 as an interim on 30 December 1966.<ref name="Zaloga_T-64(2)">Zaloga 2015, T-64 Initial Production</ref>

History

In the 1960s, as the 115 mm U-5TS was beginning to see service in the T-62 tank to counter the newest NATO tanks such as the American M60 and British Chieftain tanks, Alexandr Morozov's design bureau at the Kharkov Malyshev tank plant was ordered to integrate the 115 mm cannon into their new tank program, known at the time as Object 430. The integration of the 115 cannon, modified to utilize two-piece ammunition to fit within the Object 430 design, was designated the 115 mm D-68 gun, or GAU designation 2A21 (the tank itself was designated Object 432 with this 115 mm cannon).[1] Despite this upgrade, Morozov's team decided the 115 mm was not lethal enough to engage the NATO tanks outside of their threat envelope, with also the fear that the 115 mm D-68 was not sufficient against the Chieftain particularly.[2] Morozov looked into options for a stronger armament for their tank, which would be adopted as the T-64 with the 115 mm D-68 as an interim on 30 December 1966.[3]

Three guns would be developed as possible options for the T-64, two smoothbore 125 mm guns named D-81 and D-85, and a rifled 122 mm D-83 gun. The D-83 was quickly abandoned, and the D-85 was deemed too complicated and expensive.[4] This left the smoothbore 125 mm D-81 gun as the sole contender. The 125 mm D-81 began development as far back as 1961 as a more lethal gun over the T-62's 115 mm gun, aiming to have a muzzle velocity of up to 1,800 m/s. OKB-9 began drafting and designing the gun that would become the 125 mm D-81, GAU designation 2A26. The gun itself was derived from the 115 mm U-5TS, which OKB-9 also developed, with similarities in breech construction and recoil mechanism.[5]

The 126 mm 2A26 guns were tested in Object 434 prototype tanks in 1966. The Object 434 would be approved for Soviet service in May 1968 as the T-64A, first delivered in January 1969.[4] Following troop trials, the 2A26 was improved based on complaints such as low barrel life with the 2A26M in 1969. A further improvement in the 2A26M2 adapted the gun to fire with the T-72's autoloader.[5]

The 2A26 gun was further modernized in 1970 into the 125 mm 2A46 model, which implemented newer production methods to the barrel for increased barrel life and implemented a hydraulic recoil buffer fluid expansion compensator mechanism.[5]

Media

Excellent additions to the article would be video guides, screenshots from the game, and photos.
