Don't know for sure, the VALs will dive bomb any US ship away from the docks but not ships in the docks. So I substituted zeros with bombs and those will happily bomb anything afloat, either underway or in the docks. Maybe if I change the US fighters with SBDs a dive bomber would attack a dive bomber.
Fighters are mostly for show anyway, as Jake Grafton said, "Fighter pukes make movies. Bomber pilots make HISTORY."
