I would think that would be up to the mission commander to decide, as opposed to the mission designer. Wouldn't it?
Except for the seaplanes, (at least on blue) I think all carriers could spawn all planes. Though I could be wrong. So, maybe in a similar scenario in the future, the mission commander could simply say, "fighters spawn at carrier X and Bombers at carriers Y & Z".
If the misssion was designed with one carrier, one plane and say, the carrier that spawned fighters got sunk, it could mean a bad situation for that team.
Cheers,
