Introduction

対潜兵装です。
もっとも標準的な爆雷投射機です。
駆逐艦・海防艦等の小型艦艇に対潜水艦用火力として装備されました。
若干旧式化しつつありますが、敵潜を発見さえできれば、その威力は十分です。

The standard depth charge of the fleet, it's mainly used by destroyers, coastal defense ships, or other smaller ships for anti-submarine duty.
While a bit obsolete, it does the job once the enemy submarine has been located.

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.
