A torpedo weapon developed and deployed by the US Navy.
When the 6 bow tubes are combined with the stern tubes, the submarine is capable of launching a 10 torpedo spread.
The more reliable late-model torpedoes were an overwhelming menace against Japanese convoys and escort vessels.
It severely limited the ability of the Imperial Japanese Navy and Japan to prosecute the war.


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.
