Depends on which you are running, STF or CTF, but Yamato and Musashi aren't in my experience required even for Medium difficulty in CTF. Fusou-class Kai ni, Italia/Roma and Nagato-class should be good enough. Even for STF I'd say this is the case, though Yamato-class will be of more use there.

In any case, it is the escort fleet that you rely on to kill the boss anyway. The main fleet is for clearing side mobs mainly, and hopefully lowering the boss health a bit while at it. Use the best ships you have on the escort fleet, and be sure to include some Torpedo Cut-in ships. One AACI ship girl should be deployed too, preferably Maya Kai ni or Akizuki, but two is unneccessary I think, though not necessarily a bad choice.
