Introduction
対潜兵装です。
いわゆるアクティブソナーです。
性能は残念ながら、ものすごく高くはありません。
それでも、他兵装と組み合わせて、練度の高い駆逐艦で敵潜水艦隊を文字通り駆逐してください！
An anti-submarine weapon.
Also called the active SONAR.
It does not have impressive performance.
However, when used in tandem with other equipment, a veteran destroyer will surely put enemy submarines down!
Mechanics
Sonars are the main equipment used for ASW, being required to trigger most OASW, and greatly enhancing ASW Damage Synergy. Their main stat is "ASW"

Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks.
The flat armor penetration value is calculated as follows:
