“We have 11 carriers. 4 are currently deployed. The rest are in port for maintenance, repairs, etc. I understand that they are complicated, and need maintenance, but less than half of them out in the world at any given time just doesn’t seem reasonable.”
I guess you didn’t read your link! 7/11 = 64%.
FOUR are in for maintenance.
THREE are in pre-deployment training and exercise. One deploys this month and the other two in a a few months.
I spent 3 yrs in the Army, so I know nothing about carriers or the Navy. That said, “pre-deployment training is not the same as “deployed”.
