A carrier's aviation spaces can support helicopters from accompanying escorts as well as its own air group. An escort can send its aircraft over for maintenance that is difficult to carry out in the smaller ship's facilities. That wider task consumes workshop and hangar space even when the carrier appears to have room for more embarked aircraft. Counting aircraft parked aboard therefore misses part of the carrier's aviation support role.

Escort helicopters give carrier maintenance spaces a fleet-wide purpose beyond the embarked air group.
