I would recommend at least 2 dedicated OASW ships in your secondary fleet, since from my experience running E7E, the boss rarely requires going into night battle to finish her off, and even if it did, it didn't require more than 2 ships outfitted for it if you did the debuff.

Ideally, if you have Asashi Kai2D, use her for OASW as one of your DDs. Otherwise, since I dunno what levels your ships are, you could put two type 3 sonars on Kitakami or Ooi if they're max leveled, or another dedicated OASW DD.
