Maybe in war establishment but the standard V1 and V2 divisions of a USN carrier only have enough people to run full air wing cyclic operations in a single shift. Of course a carrier can operate less aircraft therefore requiring less manning in a split shift operation but you are going to need to offload the aircraft. ASW carriers with smaller numbers of aircraft with much longer cycles can operate 24-7 because far fewer personnel are needed on deck at any one time.The bit about the air department only having one shift is incorrect. A USN carrier can operate 24/7 with each watch doing 12 hours.
200 sorties a day is what you get running a full air wing though cyclic operations for 12 hours. That’s only eight events of 25 launches and recoveries each. Also the carrier can flex deck with cycles reduced to 40-60 minutes for higher threat readiness of throughput of bombs on target (if within range). Flex decking means many more but smaller events and less time spent in the air as aircraft can recover as soon as they are back to the carrier’s pattern and not have to wait longer for the next available cycle.
