The lost Zumwalt railgun fleet concept

Could a fully funded Zumwalt class with working railguns have transformed U.S. surface warfare?

Yes in principle, especially in a long war after missile stocks decline, but the class lost that promise when procurement and weapon development collapsed.

The prompt presents Zumwalt as an attempt to carry late-Cold-War ambitions for railguns, lasers, and advanced close-in weapons into a new surface combatant. Congressional retrenchment and weapon-development failures left only a few expensive ships without the systems that justified the concept. The operational premise behind the railgun still has merit. In a prolonged conflict where both sides rapidly deplete missile inventories, a mature railgun battery could make such a ship exceptionally powerful.
