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.

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.
