Introduction
旧式化したA型砲、その余剰装備を元に全面改修を実施、両用砲に換装した戦時改修if駆逐艦主砲です。
最大仰角、装填機構の換装、高射装置との連動も含め、従来のA型砲とは全く別の特型駆逐艦用主砲兵装となっています。
両用砲として、ある程度対空戦闘も可能です。
A what-if remodel of what would happen if the remaining obsolete Type-A guns underwent an extensive mid-war upgrade and conversion into dual-purpose main guns for destroyers.
With improved maximum elevation and loading mechanisms, as well as being combined with a fire director, this Type-A gun has become a completely new main gun for the Special-Type destroyers.
As a dual-purpose gun, it is capable of limited anti-air 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.
High-Angle Guns (sometimes "dual-purpose guns"), are anti-air focused guns, that can serve their main surface role, in addition to having extra 
AA stats.
- They are notably required in most AACI.
