Introduction

対潜水艦に使用する増加爆雷装備です。爆雷は戦訓を踏まえ、改良されています。
駆逐艦や海防艦などに爆雷投射機やソナー類などの対潜装備ともに装備することで、対潜能力の向上が図れます。

This is additional depth charge equipment for use in anti-submarine actions. The depth charges have been improved from wartime testing.
When equipped in combination with depth charge projectors, sonar, and such anti-submarine equipment on Destroyers, Coastal Defense Ships, and the like, anti-submarine ability will increase.

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.
