Skilled Sonar Personnel + Late Model Bow Torpedo Mount (6 tubes)

Introduction

潜水艦の艦首に装備する潜水艦専用兵装の改良後期型です。
水上艦搭載のものよりやや直径の小さい、必殺の潜水艦搭載酸素魚雷。その無気泡発射管の改良後期型艦首6門と熟練の高いソナー員達の組み合わせは、高い攻撃力と生存性を潜水艦に付与します。

The late-model, improved version of a sub-excl.ve weapon fitted to a submarine's bridge.
A highly accurate oxygen torpedo, slightly smaller in diameter than the ones carried by surface ships. This combination of a set of six improved, later model torpedo tubes that don't leak air bubbles and a highly trained sonar crew give submarines high attack power and survivability.
