Type 93 Passive Sonar

Introduction

対潜兵装です。
いわゆるパッシブソナーです。性能は残念ながら、あまり良くはありません。
でも、あるとないとでは大違い！対潜作戦のお供に、ぜひどうぞ！

An anti-submarine weapon, also known as the passive SONAR. It may not perform its job well, but it's better than nothing. Please use it for anti-submarine operations!

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)
