Dozens would technically mean more than 12. A plural means more than one, and one in the case of a dozen is 12.
NATO has 16 of the 21 aircraft carriers in the world. That would technically be dozens. I doubt there is any threat that we would send more than a few of those into, so we would not send dozens or even a dozen to anything.
When it comes to aircraft carriers, no other country even begins to compare to the USA. We get so much experience from operating a dozen or so carriers for nearly a hundred years, which no one else has. We can operate our a carriers many times better than any other country. It is truly amazing.
Other NATO countries are helped by the USA. The rest of the world's carriers are jokes.
Dozens is the plural of dozen.
One dozen is 12
Two dozen is 24.
16 is not dozens since it is only 1.4 dozen.
A baker's dozen is not dozens of donuts.
In order to get to dozens you must have reached the plural which would require 24.
