An upgraded late-model version of the submarine torpedoes mounted on the bows of 1st class submarines.
Though it has a smaller diameter compared to torpedoes mounted on surface combatants, these four late-model bow-mounted torpedoes in bubble-suppressing launch tubes are still deadly with their long range and high firepower.
This equipment is mounted on the high-speed 1st class attack submarines. Though it has a smaller number of launch tubes, an upgraded bubble-suppressing launcher, and skilled sonar personnel give the 1st class submarine increased survivability and offensive capability.


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.

When used by themselves or together with Submarine Equipment Submarine Equipment, late-model submarine torpedoes can trigger Night Cut-Ins that have higher damage modifiers than the usual Torpedo Cut-In.
