The Black Duke At the Naval Base Gibraltar.
The ship owes her nickname to the infamous first Duke of Monmouth – executed for treason in the 17th Century when he unsuccessfully rose up against James II. His sedition led to the title being dissolved and the coat of arms blacked out; the ship’s badge was suggested by the local Royal Naval Association in 1991.

HMS Monmouth is instantly recognisable from the plain black flag flying from her mainmast and the name on her stern is painted black, not red, unlike any other ship in the Navy
