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!

Notes

Ships receive a 15% ASW synergy bonus when this is used together with a depth charge projector or depth charge; and a 43% bonus when all three types are used (must be on the same ship). The 43% bonus does not apply when used together with a special DCP.
