Armor Penetration
Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks.

The flat armor penetration value is calculated as follows:

  • [math]\displaystyle{ \text{Pen} = \sum\limits_{\text{Equipment}} \Big( \sqrt{\text{ASW}_\text{Equipment} - 2} + \text{Mod}_\text{ship} \Big) }[/math]
  • With:
    • [math]\displaystyle{ \text{ASW}_\text{Equipment} }[/math] the base ASW Anti-Submarine Warfare stat of the applicable equipment,
    • [math]\displaystyle{ \text{Mod}_\text{ship} }[/math] being 1 for DE, 0 otherwise,
  • Armor penetration from equipment stacks,
  • The final armor of the targetted submarine cannot go below 1.
