White Ensign

The White Ensign is a flag used by the British Royal Navy, featuring a white field with a red cross (the Cross of Saint George) and the Union Jack in the canton (top-left corner). It serves as a nautical national symbol, identifying ships and personnel as part of the UK's maritime forces. Historically, it signifies British naval authority and heritage, and is flown on Royal Navy ships, submarines, and at naval establishments, representing pride, tradition, and maritime sovereignty.
