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 doesn't have impressive performance; however, when used in tandem with other equipment, a veteran destroyer will surely put enemy submarines down!
