Why a 25,000-ton do-everything warship is risky

Would 25,000- to 30,000-ton warships be ideal do-everything ships?

Its size would create a large target and difficult questions about numbers, basing, and employment.

A 25,000- to 30,000-ton ship would have room for extensive capabilities. Its scale would approach that of a Second World War battleship or battlecruiser. Such a large target raises questions about how many ships could be built, where they could be accommodated, and where they would serve. Those practical constraints underpin the objection to the proposed do-everything ship.
