Wouldn’t that be even more catastrophically expensive than the break up procedure?

That would be funding that would have be taken from somewhere. And considering how stretched thin the Navy is with new construction (Columbia class ballistic subs, new flights of Arleigh Burke destroyers, the Ford class, and the Virginia class) is there even enough money to run a refurbished Enterprise?

Plus like Safiel said the first of the Nimitz class boats will start retiring in the late 2020s. Better we learn the lesson on how to scrap these types of ships now because those are going to be even more difficult and expensive.
