The rapid rate of fire exhausts ammunition quickly: the Mikoyan MiG-31 aircraft, for example, with 260 rounds of ammunition (800 rounds maximum), would empty its ammunition tank in less than two seconds. GSh-6-23M has the highest rate of fire out of any autocannon so far. [6]
The Model 4 of this weapon adopted the same belt-feed mechanism as the Type 99 Mark 1 Model 4. The Type 99 Mark 2 Model 5 resulted from attempts to increase the rate of fire. By modifications that included the addition of strong buffer springs, the rate of fire was raised to between 670 and 750 rpm.
