Do modern warships use Chobham-like armor or any comparable protection?
Short answerNot in the old battleship sense, but critical sections may still have localized protection even when the ship lacks a traditional armor scheme.
NotesModern protection differs from the extensive armor belts and decks of earlier capital ships. Chobham tank armor is not identified as a known naval installation. Particular sections of a modern ship may still carry some form of protection even when the vessel is described generally as unarmored. The useful design distinction is between a ship-wide armor scheme and selective hardening of critical spaces.
