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

Buildable. Ships receive a boost of 15% more ASW firepower when this is used together with a depth charge launcher or depth charge, and 143% more power when all three types are used (must be on the same ship) Stock equipment of Makigumo Kai,  Naganami Kai, Amatsukaze Kai, Kiyoshimo Kai.
