I only saw one guide of this on Youtube so I decided to make my own as an alternative method.

Here's another if you want to try it without rockets: http://strategywiki.org/wiki/Battlestations:_Pacific/Battle_of_Santa_Cruz

General Tips recap:
-Leave Enterprise and South Dakota's repair on water when not personally commanding
-Head/rear divebomb Junyo's destroyers with fighter distraction to avoid unnecessary losses and save TBMs for everything else.
-Make a preemptive interception of the massive enemy air wave when spotted then replace with your own wave of TBMs.
-After the vanguard is sunk, have patience or get something to do while you wait for South Dakota to mop up (I suppose you could try sending out your remaining attackers, I didn't simply to minimize friendly casualties for the heck of it).
