Mechanics

Secondary GunsSecSp_Sec serve a similar role to Main Guns. Their main stats are the "firepower" and "accuracy" . They are notably required to trigger some weaker Artillery Spotting attacks as well as some Night Cut-Ins, notably the "Double Attack" (DA).

• They do not have any "Hidden Penalties" on any ships.
• They bring an 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.

Can be equipped in the RE of certain ships.
