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!
Mechanics
Sonars are the main equipment used for ASW, being required to trigger most OASW, and greatly enhancing ASW Damage Synergy. Their main stat is "ASW"

Indepentant of synergies, some equipment provides additional armor penetration to ASW attacks.
The flat armor penetration value is calculated as follows:
