What does the command pennant signify?

The command pennant signifies the authority of a ship's captain. When a vessel hoists a command pennant, it indicates that the captain is in command of the ship and has the authority to make decisions regarding its operation, crew management, and overall tactical direction. This flag is a clear visual cue to both personnel aboard and other vessels nearby about who is in charge.

The command pennant plays a crucial role in naval customs and traditions, reinforcing the chain of command and ensuring that roles and responsibilities are clearly established. This is particularly important in joint or multi-ship operations where clarity in leadership can affect coordination and mission success. It represents not just the responsibility of the captain but serves as a reminder of their authority and accountability while at sea.
