My brother spent 4 years on the Vinson in the 80s. It's a big fucking target, and it's vulnerable. The Australian diesel-electric submarine Onslow closed to within 300 meters of the Vinson without being detected and "sank" her during RIMPAC 98. The Democratic People's Republic of Korea has several modern diesel-electric submarines. They are very quite and pose a significant threat to a carrier.
