@Baron:
In addition, Planes cannot hit submarines without Destroyers, makes the Carriers very vulnerable against Submarines.
While, historically, Escort carriers were specifically used in submarine warfare.
I don’t think the carriers went on sub hunting alone. I believe they were accompanied by some destroyers too.
But, to your case.
I think the sub should roll a preemptive first strike against the carrier.
Then the planes should roll against the sub, and the carrier if it survived should roll too.
With OOB rules only a surviving carrier is allowed to roll against the sub, the planes are not.
The problem with your house rule is that 2 fighters that defend on 4 or less are likely to kill that sub, and that will probably prevent the sub from attacking, and making destroyers obsolete. A combo with 1 battleship, 1 carrier and 2 fighters, which is all allowed to kill that sub, will turn it into a suicide mission for the sub. And of course, who wants to buy destroyers anymore ?
