Did aircraft carriers ever use their guns?
Short answerYes. HMS Formidable at Cape Matapan and HMS Unicorn in Korea are given as clear examples.
NotesHMS Formidable at the Battle of Cape Matapan and HMS Unicorn during the Korean War are clear examples of carriers that used their guns. Possible gunfire involving Ark Royal or Illustrious is recalled less firmly. The short exchange corrects the assumption that a carrier's aircraft made every surface weapon irrelevant. Carrier armament could still matter when a ship encountered a target within gun range.
