Trivia

This gun is the modified version of the twin-gun Model B which was used by Ayanami-class and Akatsuki-class destroyers. The main difference between Type A and Type B is that instead of the former's elevation range of −5 ° to +40 °, type B's range is upgraded to 75 °, which is required for the more complicated and effective AA systems installed on newer destroyers. Type B armor, however, was too thin to withstand heavy seas and splinter damage, thus the Type B Kai was introduced, adding more protection.

First mounted on Hatsuharu-class destroyers, but its effectiveness is unknown.
