Type-A Ko-Hyoteki if she's under level 10, then you can swap for a 61cm Quintuple (Oxygen) Torpedo or 53cm Hull-mount (Oxygen) Torpedo if you have those, if not, just keep the Hyoteki.

A lot of people prefer using Turbines on their submarines though to increase their evasion instead of using weaponry. It depends on what you're doing and what your girls need.
