Introduction

紅茶の国が開発した強力な対潜兵装です。対潜爆雷に代替する次世代の対潜兵装として開発された、前方投射式の多弾散布型の対潜迫撃砲です。ハリネズミと呼ばれたこの革新的な新型対潜兵装は、比較的シンプルな構造でありながら対潜戦闘に大きな進化をもたらし、改良を施されつつ戦後の艦艇にも装備運用されていきます。

A powerful anti-submarine weapon developed by the Country of Tea.
It's a next-generation anti-submarine weapon designed to replace depth charges. It's a forward-projecting multi-round anti-submarine mortar.
This innovative new anti-submarine weapon is known as the Hedgehog. It has a simple construction but it's a revolution in anti-submarine warfare. After some upgrades, it was deployed aboard post-war ships.

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.
