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.
• Is required for AACI n° 37.
