Did Royal Navy ships really paint the Union Jack on turret roofs?
Short answerSome did, chiefly to help allied and British aircraft identify the ship from above and reduce friendly-fire mistakes.
NotesA viewer asks whether painting the Union Jack on a turret was a real practice. Some ships used the marking for recognition from aircraft overhead, especially when operating with allies. Similar silhouettes could make a British cruiser difficult to distinguish quickly from a Japanese ship. Royal Navy aviation was also vulnerable to misidentification, so the marking helped British forces as well as allies. The visible flag was an operational answer to the persistent risk of friendly fire rather than decoration alone.
