The secret weapon "Type 93 Oxygen Torpedo" known for its power and long range.
This is the prototype sextuple [Oxygen Torpedoes] firing tubes created by loading the oxygen torpedoes as much as possible, and one of these has more torpedo firepower than an older-class destroyer would have.
There were plans to equip the new later-model destroyers with these.


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


Not to be confused with other torpedos of this family (see here).
