The International Code of Signals uses 26 alphabetical signal flags, 10 numerical pennants, and several special flags to communicate between ships at sea. Developed from earlier systems dating to the 17th century, the current International Code was adopted in 1857 and revised by the IMO.
Each International Code signal flag has a single-letter meaning when flown alone. 'B' (Bravo) means 'I am loading, unloading, or carrying dangerous cargo'. All 26 letter flags have distinct meanings used in naval and maritime communication.
