Do paint schemes still matter in modern naval warfare?
Short answerProbably less than before, but not necessarily zero: haze grey may still make visual detection harder, especially through a submarine periscope.
NotesMore colorful national paint schemes would give modern warships a stronger peacetime identity, especially when combat is expected beyond visual range. Even a small visual advantage can still matter. A submarine may use a periscope for identification or attack, and a grey hull can merge with sea and haze more effectively than a bright one. Paint therefore remains a tradeoff between peacetime identity and a modest wartime visual advantage.
