"Semper Paratus" is a 1928 song and the official march of the United States Coast Guard, having been composed in 1927 by U.S. Coast Guard Captain Francis Saltus Van Boskerck.

USRC Surveyor was a ship of the United States Revenue Marine captured by the United Kingdom during the War of 1812. Despite the vessel's loss, the "gallant and desperate" defense of her crew against a superior force of the Royal Navy and the Corps of Royal Marines is commemorated by the United States Coast Guard. Along with the Royal Navy frigate which bested her in battle, HMS Narcissus, Surveyor is among six legendary ships memorialized in the lyrics of the Coast Guard march "Semper Paratus".
