Introduction
世界に衝撃を与えた特型駆逐艦、その初期型である吹雪型に採用された駆逐艦主砲A型です。
防盾で全集を遮蔽して弾片及び荒天対策に対応、比較的軽量で当時としては優れた駆逐艦装備でした。
平射砲であるため、対空射撃には不向きです。
This is the Model A main gun used by the early-model Fubuki-class, the special-type destroyers that shocked the world.
With a covered turret that protected against shrapnel and stormy seas, this was a lightweight and outstanding destroyer gun for its time.
Being a low-angle gun, it is not suited for anti-aircraft use.
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 boats.
