John F Kennedy has some serious problems. The ship was so poorly maintained that the CO was pretty much drummed out of the navy and the ship was retired earlier than expected. I expect that the problems started quite a bit earlier than that.
Quality of life on board US Navy ships is much better than it used to be as far as ship's structure and facilities.
I was on her way back in the 70’s........CO was a tough bastard, who started out as an e-1...he ate what the men ate, and would not hesitate to throw a cook in the brig...this captain went on to become a vice admiral..now when I was on the forrestal, it was a whole different ballgame...that ship was disgusting, filthy, chow halls closed due to health issues...
I was on JFK in ‘74-’76 and the food wasn’t any better. She was fairly new then but even then maintenance was deferred. Just slap some paint on it and it will go away.
