Introduction

増大する潜水艦の脅威に対抗するため開発された、革新的な次世代の対潜前投ロケット弾兵装です。
実機は不具合の多発により運用上の問題を抱えていましたが、本兵装は改良によって不発率の低下に成功したif改修兵装です。
本兵装のコンセプトは、あの名対潜兵装アスロックへと受け継がれていきます。

This is a revolutionary next-generation forward-firing anti-submarine rocket weapon developed to counter the increasing threat of submarines.
The base version was plagued with problems during actual use, but this is a what-if version where improvements succeeded in reducing the rate of misfires.
The main concept behind this weapon was succeeded by the famed ASROC ASW weapons system.

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.
