The carrier my father was on 40 years or so ago (USS Bennington CV-20) was recently towed to the far east (at a fuel cost of something like $27,000/day for a six week trip, or so) to be dismantled as scrap metal. There must be pretty good money in it to justify that kind of towing cost.
They chop them up.
