The nuclear industry likes to lowball the cost of SMRs (heart of nuclear ships), but the overall cost difference of power types is the truth. Aircraft carriers are also 4x the cost of diesel, but with only 2x the operational costs (inclusive of similar functions of managing planes). An aircraft carrier requires 1000 extra crew to supervise the reactor.
