NATO's navy signal flags, more than just colourful banners.

Signal flags have played a crucial role in maritime communication for centuries. These colorful and visually striking flags are more than just decoration; they serve as a vital method for transmitting messages across vast oceans and between ships. Each flag represents specific letters or numbers, allowing them to be combined to form words, codes, or convey standalone meanings. This timeless form of communication has been an integral part of naval and merchant vessels since the 18th century and continues to be employed by NATO navies in situations where radio communication is not feasible or secure.
The use of signal flags not only embodies practical utility but also embodies a deep maritime culture and tradition. To gain a deeper understanding of the enduring significance of signal flags, watch the Chief Yeoman aboard the German Navy frigate FGS Bayern explain how these flags continue to be utilized by Allied ships to communicate essential information.
