12.7cm Twin Gun Mount

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 against splinters as well as bad weather 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 post-Mutsuki class Japanese destroyers save for the Akizuki, Matsu and Tachibana classes. Had four major variants denoted A, B, C, D respectively (A being the oldest), the main differences between the variants being the weight and the gun's elevation angle. Type A was limited to 40deg. elevation and was quite useless when it came to the AA role. Maximum elevation angle was raised to 75deg. for the B- and D-types while the C-type was capable of 55deg. Unfortunately, the firing rate at high elevation angles was very low since the loading sequence required hand ramming, which made Japanese destroyers vulnerable to aerial attacks.
