A layered escort for a carrier battle group

How many ships should protect a carrier in wartime?

The preferred group adds a command cruiser, three air-defence destroyers, four anti-submarine frigates, an attack submarine, and suitable supply ships.

The proposed screen assigns distinct jobs: four frigates concentrate on anti-submarine warfare, three destroyers on air defence, and a larger command ship coordinates both. It also includes an SSN and the auxiliaries needed to sustain the force. The proposed numbers show that carrier survivability depends on specialized sensors, weapons, command capacity, and logistics working as a system.
