Introduction

現代の水上艦装備の対潜兵装としても運用されている新世代の対潜誘導魚雷、その先行初期型です。
爆雷に替わる新世代の対潜兵装として米国で開発された、音響ホーミング形式の対潜魚雷、そのごく初期型です。
その後、年月と様々な改良が加えられ、進化発展していきます。

An early predecessor of the next-generation anti-submarine guided torpedo that is used by modern surface combatants as an ASW weapon.
This is an extremely early model acoustic homing ASW torpedo developed by the US as a next-generation ASW weapon to replace the depth charge.
After this, it would undergo many improvements over the years and continue to evolve.

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.
