The 2A46 (D-81T) is a 125mm/L48 smoothbore cannon of Soviet origin used in several main battle tanks. ==Description== It was developed by the Spetstekhnika Design Bureau in Ekaterinburg in the 1960s originally for the T-64A tank. They were then manufactured at Artillery Plant No.9 in Ekaterinburg and Motovilikha in Perm. Versions 2A46, 2A46M, 2A46M-1 2A46M-2 2A46M-4 2A46M-5 and the KBA-3(Ukrainian). 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 2-piece, in that the projectile is loaded first, followed by a separate propellant charge. The early version of the 2A46 suffered from a short barrel life, but this was subsequently rectified on the 2A46M version. The Ukrainian KBA guns are derived from the 2A46 gun. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2A46 125 mm gun」の詳細全文を読む スポンサード リンク
