There are no branching requirements aside from 2 DD and no enemy BB or CV aside from the dead ends, so there's plenty of freedom.

I don't perfectly remember what I used to clear it, but it resembled this:

- 2 DD (2 main guns + radar/sonar, since the subs are weak enough that DD base ASW will crush them)

- BBV (Helps in sub nodes, and thankfully there aren't subs in the boss node, so it can contribute fully as a BB there; also grants second shelling phase)

- CV (fighters in largest three slots, bombers in smallest to counter boss node)

- 2 CA/CAV (Again, only a Ri flagship in the ideal route, so no need for multiple BB)

CAV will be more helpful for subs (Though you shouldn't need it) while CA probably have better stats. If you're somehow really struggling with the subs, switching out the CV or a CVL is managable.

Really, just put your best ships in that fulfill the criteria of 1 BB(v), 2 DD, and some sort of airpower (Seaplane bombers in Ise-class's larger slots can help).
