This proved to be baseless because later operation proved that the reliability of the automated system was just as good as the simpler manual system.

Type 79A

Based on the successful performance of the automated system, the manual backup system was eliminated in this upgrade. As a result, the total weight and size of the gun mount was reduced. Beside the obvious different in size, the most obvious visual external difference between Type 79
