Why a nuclear Zumwalt cruiser would be a new design

Could the US Navy revive and enlarge the Zumwalt hull into a 25,000-ton nuclear cruiser?

The panel considers it possible but prefers a new design and stresses the cost of changing shipyard tooling again.

A proposed 25,000-ton nuclear cruiser with six-inch guns is treated as theoretically possible. The answer favors developing a better design for current needs, while allowing that it might make a similar choice of hull form. Reopening production also raises a shipyard problem. Bath Iron Works is described as having retooled for Zumwalt and then retooled back to Arleigh Burke construction. Reusing a hull idea therefore needs to be considered separately from paying to restart the earlier building program.
