While the traditional naval practice of separate wardrooms/messing for enlisted, chiefs, and officers is standard knowledge, something I did not know about until this week was the practice of “Admiral’s China,” especially reserved for visits to capital ships by flag officers.
From the Battleship USS Alabama Museum:
The Officers dined on the Officers china, printed with the iconic anchor on it. Their meal was served in the Wardroom, the Officers’ dining room. When the Captain was dining, the Captain’s china was used, the flying pennant with navy blue band and the meal served in the Captian’s dining room. Each ship carried a set of china used when an Admiral was aboard the ship. The Admiral’s china features a gold band and insignia.
