War with Iran? The first thing they'll do is block Hormuz. Any carrier trapped in the Gulf won't be floating for long. The rest will hightail it to Norfolk and wait it out while either President Hillary airlifts C-5s full of cash or President Trump nukes them.
Like I said, too expensive to risk losing.
LOL...nailed it!
A carrier group would not enter the straits of Hormuz. They operate outside the missile range of the Iranians. And there are defenses against missiles including electronic and anti-missile missiles.
