What it says on the tin. What would be the needed developments or conditions for big gunned warships to become relevant again? My money is on railguns, likely brought on to counter improving CIWS via hurtling a very big shell at insane speeds at the target. As I understand it, given that modern warships aren't nearly as heavily armoured as their predecessors (because missiles make it vaguely useless), a single salvo from a Queen Elizabeth class super dreadnought would sink any vessel afloat.
