Introduction

艦隊型日本駆逐艦に搭載された主砲のif改修型です。
本来D型砲への繋ぎ的存在だったC型砲に、数々の戦訓を取り入れた実践的な改修を実施。
さらに、対空近接防御として25mm機銃専用機銃座を新設し、対空及び水上電探との連携運用も考慮した日本駆逐艦用兵装です。
春の雨の名を冠する駆逐艦にも最適な、限定的ながら対空戦闘にも有効な改修駆逐艦兵装です。

A what-if upgraded version of the main gun mounted on Japanese fleet destroyers.
The Model C that was meant as a stop-gap model preceding the Model D, has been given an upgrade incorporating several lessons learned in combat.
Additionally, a new 25 mm machine gun mount has been installed for close-range anti-aircraft defense, and this weapon is designed for use in conjunction with Japanese destroyer's anti-aircraft and surface detection systems.
It is a modified destroyer weapon that is ideal for the destroyer that bears the name of Spring Rain, being also reasonably effective in anti-aircraft combat.

Mechanics

Main Guns are the main armament used by surface ships. Their main stats are the "firepower" and "accuracy" . They are notably required to trigger all Artillery Spotting attacks as well as some Night Cut-Ins, notably the "Double Attack" (DA).

Most main guns come with "Hidden Fit Bonuses/Penalties", especially larger ones.
Small Caliber Main Guns bring some accuracy bonus against PT Imp.
Is required for AACI n° 47.
