Introduction

艦隊型駆逐艦の主砲です。
防盾で全周を遮蔽、弾片や荒天対策を施しており、また動力操法も採用した近代的な小型艦の主砲で、多くの主力駆逐艦に採用されました。
あまり仰角はとれず、対空射撃は少し苦手です。

"The main gun of fleet destroyers. Shielded for defense toward splinters as well as bad weathers and equipped with powered turrets, this modern main gun for small vessels was equipped on most fleet destroyers. Due to its low elevation angle, anti-air firing is not its forte."

The main gun for most of Japanese destroyers post-Mutsuki class save Akizuki class, Matsu class and Tachibana class. Has four major variants denoted A, B, C, D respectively (A be the oldest), the main differences be its weight and the gun's elevation angle. Type A only had 40deg. and was extremely helpless when the thing came to AA firing. Max. elevation angle was raised to 75deg. for B- and D-type while C-type had 55deg., but with its loading sequence required hand ramming the firing rate at high elevation angle was very low, making Japanese destroyers vulnerable to aerial attacks.
