The ideal submarine for E-5 is Goya Kai (lvl. 50 minimum), since she gets 2 equipment slots (minimum equipment count requirement for cut-in) and a whopping 50 base luck (very high cut-in chance).

However, as long as you have a submarine in the 2nd Fleet (and if the rest of your fleet can handle taking down the enemy fleet), then a non-kai submarine is fine.
