The 2A46 (D-81T) is a 125mm/L48 smoothbore cannon of Soviet origin used in several main battle tanks.


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. Commercially produced 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.

Tanks using the 2A46[edit]

The 2A46 has been used in numerous tanks, though these are almost exclusively Soviet/Russian designs or foreign derivatives thereof.
