Thanks for the info, pbehn.
What I was looking for was the various types of fire directors used on vessels, the mechanical part as opposed to the human part.
From the limited info I know, dual purpose weapons on capital ships would have directors, generally with x amount of guns under the control of each director. Smaller caliber AA (40mm or so on down) often had a computing sight, a mini director of it's own in essence, or smaller weapons sometime had nothing.
For instance the 25mm triple mount generally had the type 95 director, while single mounts did not have any type of directors and was done manually with just a standard sight.
