Kilo Signal Flag (K) – International Nautical Signal Flag
The Kilo signal flag, also known as the K nautical flag, is a bold yellow and blue flag that represents the letter K in the International Code of Signals.

Traditionally used as a request for communication between vessels, the Kilo flag sends a clear maritime message:
“I wish to communicate with you.”
