There are NO redundant US carriers. The non-nuclear carriers that have been retired (Forrestal, Saratoga, Ranger, Independence, Constellation) are all in Cat X maintenance status (essentially left to rot) and have been out of service for between 3 and 12 years. More to the point they are all well in excess of 40 yrs old anyway and require around 3000 bodies to run excluding the airwing. The remaining two (Kitty Hawk and JFK) will retire in the next couple of years but again are sh*gged out - JFK commissioned in 67 and the USN can't wait to bin her due to her material condition.
CVF or bust I'm afraid.......
