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.

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.
