Introduction

増大する敵潜水艦による脅威に対抗するため、三式爆雷投射機を集中配備。
舷側方向に対して、片舷6~8基、両舷12~16基の爆雷投射能力を誇る、対潜艦艇用の対潜制圧兵装です。
日振型の次級である、鵜来型以降に装備され、海上護衛や対潜哨戒に威力を発揮しました。

A more concentrated deployment of Type 3 depth charge launchers, in order to counter the growing threat from enemy submarines.
An impressive shipborne weapon for submarine suppression, able to throw 6-8 charges per side for an impressive total of 12-16 charges.
Equipped on the Hiburi-class's successors, the Ukuru-class, where they came into extensive use in convoys and anti-submarine patrols.

Mechanics

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

ASW Damage Modifiers: [math]\displaystyle{ \text{Mod}_\text{synergy} = {Mod}_\text{1} \times {Mod}_\text{2} }[/math]
[math]\displaystyle{ {Mod}_\text{1} }[/math]   +  
(Any Sonar + Any Depth Charge)
1.15
[math]\displaystyle{ {Mod}_\text{2} }[/math]  DCP +  DCR and NO  Small 1.1
 Small +  DCP +  DCR 1.25
Examples
[math]\displaystyle{ \text{Mod}_\text{synergy} }[/math]  Small +  DCP +  DCR 1.4375[math]\displaystyle{ 1.15 \times 1.25 }[/math]
 Large +  DCP +  DCR 1.265[math]\displaystyle{ 1.15 \times 1.1 }[/math]
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   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.
