There are over 5,000 personnel on a US Nimitz class carrier alone. Then you have 2-3 DDGs with about 1,000 more, and a Tico with over 300 more and then at least one sub with 150 or so.Carriers do not sail on their own they sail part of the overall carrier task group
...for USN there's over 5,000 personal in the entire strike group and that costs around $2.5 billion per year if deployed 24/7, that is why Ford Class is cheaper less manpower and will save $4.8 billion over the lifetime of the carrier
But put it this way, there is no cheap way to run a carrier strike group, only top tier navy’s can afford it, it’s a good way for small country’s to go bankrupt
So, altogether a US CSG will have more like 6,500 personnel...and that does not include the AOR or its escort.
Now, a Ford carrier cuts down about 1,000 personnel on the carrier...so it will run cheaper in overall costs in terms of manpower, feeding them, clothing them, etc., etc.
