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.
