Introduction

対潜水艦に使用する増加爆雷装備です。
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 used for anti-submarine warfare.
Equipping it together with other ASW equipment such as depth charge projectors or sonars on destroyers, coastal defense ships and the like can increase their anti-submarine capabilities.

DCP + DCR	1.1x

Large + DCP + DCR	1.265xLarge + = 1.15x DCP + DCR = 1.1x 1.15 * 1.1(1 + 0.1) = 1.265x
Small + DCP + DCR	1.4375xSmall + DCP / Other = 1.15x Small + DCR = 1.15x DCP + DCR = 1.1x 1.15 * 1.25(1 + 0.1 + 0.15) = 1.4375
Armor Penetration
Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks. The affected equipment are: DCR: Type 95 Depth Charge, Type 2 Depth Charge, Lightweight ASW Torpedo (Initial Test Model), Hedgehog (Initial Model), DCP: RUR-4A Weapon Alpha Kai, Mk.32 ASW Torpedo (Mk.2 Thrower). 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 stat of the applicable equipment, Visible bonuses and Improvements are not counted here. [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.
