Broad pennant

A broad pennant is a triangular swallow-tailed naval pennant flown from the masthead of a warship afloat or a naval headquarters ashore to indicate the presence of either: (a) a Royal Navy officer in the rank of Commodore, or (b) a U.S. Navy Captain serving in a designated Commodore command billet.

In 1958, the rank of First Class Commodore was terminated, after which only the red and white broad pennant with a ball was used by the Royal Navy.

In the U.S. Navy, the blue and white pennant will contain either numbers or letters indicating the command designation or name.

Likewise, the Commodore commanding Strike Fighter Wing Atlantic will have the letters "SFWL" or "CSFWL" on their pennant.

It is also carried at the bow of a boat in which they are embarked, emblazoned on their social letterhead, displayed on a staff in his or her office ashore, and, if they should die in command, half-masted aboard their flagship and carried before their casket in the funeral ceremony.
