Would navies reconsider nuclear-powered surface combatants despite their Cold War cost?
Short answerYes, especially if China built one as an operational ship and a stepping stone toward nuclear-powered carriers.
NotesThe United States retired its nuclear cruisers when their cost no longer answered a clear peer requirement. Their disappearance resembles the withdrawal of battleships once nobody was building a counterpart that demanded one. A modern navy would probably label a large nuclear-powered surface combatant a cruiser, even though the US Navy previously used nuclear destroyer classifications, because the name would distinguish it from conventional escorts. If China used a cruiser-sized ship to mature surface-reactor technology, the United States would face pressure to respond. Renewed competition could make an expense rejected in the post-Cold War environment appear strategically necessary again.
