Perhaps "resupply" would have been a better word.

you are correct I did make a mistake there.

However, like the other comment suggested, nuclear carriers rarely travel alone without the protection of large naval assets deployed around it.

If only AI was running all of the naval air assets on a carrier, no food, self sustaining & maintaining.

I'd imagine an increase of frequency in US naval carrier groups patrolling oceans closer as a result of the cost savings of reducing manned staff with AI and robots but that's another topic.

Escort ships need to be refuelled; the plurality of a carrier group is oil-burning.
