nice work
but i wonder if you can you tie them to carriers instead so whenever you are around a carrier, either by itself or in port, you always have air cover around it?
that would be a great realism boost since carriers dont have air cover like they should and task forces without carriers probably shouldnt always have air cover because when you are out of range of land bases and there are no carriers then you shouldnt have any air cover.
if there is some unreal parts to air cover its better to always have it then never to have it i guess.
