Introduction

?

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.
