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. Boosts ASW damage 15% when used together with a depth charge (both must be on the same ship).
