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.
