Introduction

米国で開発・実戦配備された優れた両用砲。
同駆逐艦クラスの搭載主砲として、広く運用された単装砲兵装です。
対艦戦闘及び対空戦闘両面で優れた実用性を発揮した本砲は、あのフレッチャー級駆逐艦や、レイテ沖で栗田艦隊主力からタフィー3護衛空母群を護って奮戦した護衛駆逐艦などにも、主砲として装備されました。

An excellent dual-purpose gun developed and deployed by the US.
It was extensively used as the main armament of US destroyers in single gun mounts.
It displayed both excellent anti-ship and anti-air capabilities. It was the main gun of the Fletcher-class destroyers, as well as the destroyer escort that fought hard protecting the Taffy 3 escort carriers from the main force of the Kurita Fleet at Leyte.

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.

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.
• Is essential for AACI n° 35, 36.
