I mean its a surface warfare ship using s350s for AD. If it has nukes we saw that from orbit or when they flew those 3 navy flights over it yesterday. Unless they have some sort of sort of new ballistic shielding, which is unlikely. F35s walked all over s400s in syria and this has sub that system. This one ship can't really transport ICBM, though it does house some cruise missiles. Not really the cuban missile crisis 2.0 OP.
