HEAT: 905-950 m/s HE: 4,000 m The 2A46 (also called D-81TM) is a 125 mm/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-64 tank.

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 in two pieces: the projectile is loaded first, followed by a separate propellant charge.

In addition, the Chinese ZPT-98 is based on 2A46M imported from Russia's T-72 or T-80.
