The scenario transfers anti-submarine work that historically consumed fleet carriers to the lighter ships. That division may prevent ships like Courageous from being committed to exposed anti-submarine patrols. It does not remove the need for surface escorts, because every additional carrier becomes another valuable unit requiring destroyers and cruisers for screening. Britain historically lacked enough of both types to cover all its commitments. A stronger aviation arm therefore intensifies the escort shortage.

More carriers also mean more escorts
A wider carrier fleet improves scouting and anti-submarine options, but it deepens the Royal Navy's recurring shortage of destroyers and cruisers for escort duty.
