What a surviving nuclear surface fleet changes

What changes if 1980s nuclear strike ships are built and retained into the 2000s?

They would probably be redesignated as cruisers, and retaining them might sustain nuclear surface-warship production and make carriers cheaper.

The hypothetical nuclear destroyers would probably be redesignated as cruisers. Keeping them in service into the 2000s might support continued construction of nuclear surface warships. Cheaper aircraft carriers are also suggested as a possible consequence, without a detailed cost explanation.
