 Along with a high rate of fire, the fairly heavy round () used by the Kortik is comparable to the DPU rounds of the GAU-8 Avenger (), although the muzzle velocity (and therefore both the kinetic energy and effective range) is slightly lower, partially offsetting the high caliber and rate of fire.The missiles used in the Kortik are the 9M311 missiles, which is also used on the 9K22 Tunguska.The 9M311 is a SACLOS guided missile, however, it is steered automatically by the command module.
