A mix fleet of course. The BAF and Sairs usually pew each other once a week with a mixed fleet that usually consists of a few battleships and cruisers, a few gunboats and many more snubs.
You'd need something like 2 battleships, 2/3 cruisers to support the battleships. A few gunboats to support the cruisers then the rest being a mix of bombers and fighters. Usually they both require a lot of people on each side so that might be your biggest problem.
