Framed International Code of Signals Uniform (U) Linen Flag

Framed International Code of Signals Uniform (U) maritime signal flag, professionally mounted within a shadow box display. Constructed of alternating red and white quartered linen panels, the flag retains its original canvas hoist, rope lanyard, and wooden toggle. When flown alone, the Uniform (U) flag means "You are running into danger." It is used to warn another vessel that it is standing into a hazardous situation, such as shoal water, submerged obstacles, or other navigational dangers. The canvas hoist bears the Annin Flag Company "Defiance" label. Annin is America's oldest flag maker. International Code of Signals flags were widely used aboard naval and merchant vessels to communicate standardized navigational, operational, and safety messages before the widespread adoption of radio communications, and they remain an internationally recognized maritime signaling system today.
