Strategic sealift, specialist support, and the combat-logistics ships that replenish an operating carrier group serve different functions. Fleet oilers, dry-cargo ships, and fast combat support ships such as Supply and Arctic move aviation fuel, weapons, and stores from port back to the force. An ideal rhythm assigns at least two supply ships per carrier group so one can replenish the fleet while the other reloads ashore. Those auxiliaries are vulnerable enough to require escorts, tying their usefulness to frigate and destroyer numbers. Carrier persistence therefore depends on a protected shuttle system rather than simply on the carrier's own magazines.

The combat-logistics force keeps carriers on station
Military Sealift Command oilers and supply ships alternate between ports and carrier groups, but their own escort needs turn logistics into a force-structure problem.
