This gun is the modified version of the twin gun Model B which was used by Ayanami-class and Akatsuki-class destroyer. The main difference between the 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, so the Type B Kai was introduced, adding more protection.
First mounted on Hatsuharu-class destroyers, but the effectiveness is unknown.
