Introduction

対潜水艦に使用する増加爆雷装備です。
装填爆薬の改良、爆発深度調整幅の拡大、誘爆対策など、爆雷は戦訓を踏まえ、実用的に大きく改良されています。
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ともに装備することで、対潜能力の向上が図れます。
一部改装駆逐艦で、さらに高い運用性を発揮します。

A supplementary depth charge for anti-submarine use.
Using lessons learned in combat, these depth charges have been upgraded with a larger explosive charge, wider operational depth, and resistance to secondary explosions.
You can improve the anti-submarine strength of destroyers and coastal defense ships by equipping this along with depth charge projectors and sonars.
It has even greater capabilities on certain remodeled destroyers.

Mechanics

Depth Charges Depth Charges are one of the main equipment used for ASW, greatly enhancing ASW Damage Synergy. Their main stat is "ASW" Anti-Submarine Warfare.

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,
Note
  • Armor penetration from equipment stacks,
  • The final armor of the targetted submarine cannot go below 1.
