If anything we need more ships. Just because we 11 carriers doesn’t mean they’re all deployed at the same time, some are in port being retrofitted and refit while their crews are at rest. While I agree that technology has made it easier to operate a warship with less crew you still can’t have a ship in two places at once. The Unites States has a lot of naval obligations and we have too few ships to properly do the job. Then you have China that’s building its fleet at an alarming rate so they can project their power and protect their interests throughout the world. To fulfill its obligations the navy needs close to 350 ships in operation but right now we’re closer to 265, if the current budget stays true then our numbers are in the low 200’s and that’s less than China.
