Carrier numbers, rotation, and crew endurance

The example treats a nominal eleven-carrier navy as roughly ten usable ships facing commitments suited to a larger fleet. Ten carriers might normally yield four available ships, with three operational and another ready. Sustained round-the-clock strikes would put all four forward, rotating one away from the line while the others continue operations. An approximate cycle of four weeks on and one week off illustrates the additional rotation needed within the available force. Long deployments without port visits remove the changes of scene and rest that help crews endure repetitive watches. Earlier carrier surges during the Gulf War and Afghanistan provide comparisons, but improved capability cannot let one hull occupy several places at once.
