Introduction

近代化改修された53cm連装魚雷の改良型です。
61cm酸素魚雷と比較すると炸薬量は抑え目ですが、あらゆる点で改良された運用性の高い小型軽量の魚雷兵装です。
魚雷自体も酸素魚雷に換装され、装備適正の高い一部の艦艇では特に高い運用性を発揮、魚雷戦及び夜戦火力向上が図れます。

This is an improved version of the modernized 53 cm twin torpedo mount.
Although the explosive charge is lower than that of the 61 cm oxygen torpedo, it is a small, lightweight torpedo armament that has been improved in every way and is highly operational.
The torpedoes themselves have also been replaced with oxygen torpedoes, making them particularly useful on some ships with high equipment suitability, and improving torpedo battle and night battle firepower.

Mechanics

Torpedoes are almost exlusively used to trigger Night Cut-Ins, especially the Torpedo Cut-In (TCI). Their main stat is the "torpedo" stat.

This stat is also used to calculate damages during the Opening Torpedo Salvo and Closing Torpedo Salvo.

Can be equipped in the RE of certain ships.
