Introduction

伊号潜水艦の艦首に装備する、潜水艦専用魚雷兵装の改良後期型です。
水上艦艇に搭載するものよりやや直径の小さい長射程高威力を誇る必殺の酸素魚雷、その無気泡発射管の改良後期型艦首4門です。
高速迎撃型伊号の潜高型に装備され、門数は少ないものの、優位な射点から必殺の魚雷を放ちます。

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.
It was mounted on high-speed 1st class attack submarines that make up for its smaller number of tubes by firing from more advantageous positions.

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.

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

Torpedo Cut-In modifiers
Attack Type	Prerequisites	Notes	Pre-cap Damage Modifier	Accuracy Modifier	Hits
Submarine Cut-ins	Sub_LM	With Late-Model Sub Torps ONLY	1.75	?	2
Submarine Cut-ins	Sub_LM Sub_LM	With Late-Model Sub Torps ONLY	1.6	?	2
