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戦的な改修を実施、対空戦には不向きですが、白露型・朝潮型・陽炎型、特に陽炎型駆逐艦の改装艦に最適化され、白露型の最後の一隻となった艦の改装艦の装備としても有効な、水上電探との運用も考慮された日本駆逐艦用改修if兵装です。
A what-if upgraded version of the main gun mounted on Japanese fleet destroyers.
The Model C was meant as a stop-gap model preceding the Model D. This gun has been given an upgrade incorporating several lessons learned in combat. It is unsuitable for anti-air use. It is optimized for use on the Shiratsuyu-class, Asashio-class, and Kagerou-class. It is extra effective on remodeled versions of Kagerou-class ships and the last or the Shiratsuyu-class. This what-if Japanese destroyer equipment can also be used alongside surface RADAR.
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.
