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 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.
