*Submarines are also the most resource-efficient class in the game, they cost almost nothing to deploy/repair and, in addition, make excellent, cheap additions towards multiple expeditions that utilize them.

*If you have Type A ''Ko-hyoteki'', you can put it on a submarine for extra attack before the shelling phase.  After you get a submarine to level 10, they'll have that initial attack without any equipment at all. You can replace the equipment with regular torpedoes or turbine to increase their low evasion.

*If you have [[Type A Ko-hyoteki]], you can put it on a submarine for a pre-emptive torpedo strike before the shelling phase. After you get a submarine to level 10, they'll have that initial pre-emptive attack without any equipment at all. You can replace the equipment with regular torpedoes or turbines to increase their low evasion.
