'''Submarines''' ([[SS]], also including '''"Aircraft Carrying Submarines"''' [[SSV]]) are characterized by relatively low armor and HP. By contrast, they are difficult to handle using normal "anti-ship" setups, requiring instead specific '''Anti-Submarine Warfare (ASW)''' equipment and setups in order to be sunk.

During sorties, submarines are typically found at pre-boss nodes, but some can be boss themselves, see ''[[Enemy#Bosses (SS)|here]]''.

==Damage calculation==
==Damage calculation==
The stats use to calculate damage against submarine is {{ASW}} ASW.
* When contributing to ASW power, Base {{ASW}} ASW is '''square rooted''', while equipment ASW is '''multiplied by 1.5'''
** ASW equipment is therefore the primary source of ASW damage, with base ASW playing a very minor role.
** However, base ASW is the primary determinant of whether a ship can reach 100 total ASW to perform opening ASW attacks.
* Unlike sheeling ASW damage is capped at 170.
*ASW attacks are the only one to have [[Formation]]s damage modifier above 1, with {{ToolTip|[[Combat#Formation_Selection|Line Abreast]]|[[File:LineAbreast.png]]}} being the highest at x1.3 ({{ToolTip|[[Combined_Fleet#Formation_Selection|Cruising Formation 1]]|[[File:Formation_1.png]]}} for [[Combined Fleet]]s).
