This plaque documents the Commanders-in Chief who served aboard the flagship USS Pennsylvania. Shortly after her commissioning in June 1916, the Pennsylvania was made the flagship of the Atlantic Fleet under the command of Admiral Henry T. Mayo. General Order 94, issued in December 1922, combined the US Atlantic Fleet and the US Pacific Fleet into the United States Fleet. Under the United State Fleet, Pennsylvania became the flagship for the United States Battle Fleet. The Battle Fleet operated in the Pacific and was comprised of the newer battleships and the aircraft carriers. In 1930, the United States Battle Fleet was changed to United States Battle Force. General Order 143 from February 1941 eliminated the United States Fleet name, separating the fleet into its previous division of US Atlantic Fleet and US Pacific Fleet, each with its own commander in chief. Pennsylvania retained her status as the flagship of the US Pacific Fleet.
USS Pennsylvania was in drydock at Pearl Harbor during the Japanese attack on December 7, 1941. On December 31, Admiral Nimitz took command of the US Pacific Fleet. His is the last name to appear on the plaque.
Documents show that this plaque was removed from the Admiral’s cabin, presumably in 1946 following her return to Puget Sound Naval Shipyard for repairs and preparation for the atomic bomb tests. The plaque came to NHHC from Puget Sound in 1950, a few years after the ship was scuttled following her participation in Operation Crossroads.
