A modern Belfast and the appeal of pod propulsion

Would a ship like HMS Belfast be useful in modern warfare, and what would pod propulsion change?

A modern equivalent would be much larger, and pod propulsion could improve redundancy and maintenance, though its combat hardening and shock resistance would need proving.

Translating Belfast's capability into a modern hull would point toward a cruiser of roughly 25,000 tons because modern destroyers have grown greatly in size. Electric pod propulsion is attractive because engines can act as generators, individual units can be maintained or replaced, and shaft-line vulnerabilities are reduced. Its resistance to damage and shock remains the critical military concern. Civilian operation of pod-propelled ships such as Queen Mary provides practical experience, but it does not prove that the machinery is already hardened for combat.
