when I use huge gun such as 18", paper penetration are always nice, even use semi-ballistic ap(penetration better than semi-ap less than standard ap) at 25-30km it has 60-80'' penetration over deck, way much beyond enemy possible armor. But when in a fight, ap hit enemy battleship deck at 25-30km, it always shows partial-pen, why? Under which condition can ap penetrate battleship and make devastating damage?

>Ballistics of the Shell (influenced by shell weight, shell type, propellant, gun size and barrel length)
>Armor of the Enemy Target (strength, thickness, any sloping/rounding)
>Angle of Impact
