It was developed by the Spetstekhnika Design Bureau in Ekaterinburg in the 1960s originally for the T-64 tank. They were subsequently manufactured at Artillery Plant No. 9 in Ekaterinburg and Motovilikha in Perm. Other variations include 2A46M, 2A46M-1, 2A46M-2, 2A46M-4, 2A46M-5, and Ukrainian KBA-3 and Chinese ZPT-98.
The early versions of the 2A46 suffered from a relatively short barrel life, but this was rectified on the 2A46M-1 version. Depending on the version it offers 510.00 MPa (73,969 psi) or from the 2A46M-1 650.00 MPa (94,275 psi) Pmax chamber pressure.[1]
The Ukrainian KBA-3 guns are based on the 2A46 gun. In addition, the Chinese ZPT-98 is based on 2A46M imported from Russia's T-72 or T-80.[2]
Projectiles
Projectile specifications for 2A46 and 2A46M[3][4][5][6][7][8] Note: There are different ways to measure penetration value. NATO uses the 50% (This means that 50% of the projectile had to go through the plate).
