I was just wondering if it is allowed to send more than two planes to a battle in a seazone when only one carrier could be there at the end of turn. The motivation would be that some of the aircraft would die in the battle and each individual aircraft can land on the carrier. Did not find an answer in the rulebook but probably didn’t look thoroughly enough.
You cannot deliberately send air units into combat situations that place them out of range of a place to land afterward. In the
Combat Move phase, prior to rolling any battles, you must be able to demonstrate some possible way (however remote the
possibility is) for all your attacking air units to land safely that turn. This could include a combination of combat moves. It
could also include noncombat moves by a carrier or the mobilization of a new carrier.
In order to demonstrate that an air unit might have a safe landing zone, you may assume that all of your attacking rolls will
be hits, and all defending rolls will be misses. You may NOT, however, use a planned retreat of any carrier to demonstrate
a possible safe landing zone for any fighter or tactical bomber. Once possible landing spaces for all attacking air units have
been demonstrated, you have no obligation to guarantee those landing zones for air units in the course of battle. For example,
aircraft carriers may freely retreat or be taken as casualties, even if doing so leaves air units with no place to land after
combat (such air units will be destroyed at the end of the Noncombat Move phase). However, during noncombat movement
and new unit mobilization, you must provide for safe landing of as many air units as possible after all combats are resolved.
