High Quality Content by WIKIPEDIA articles! USS Utah (BB-31/AG-16) was a battleship that was attacked and sunk in Pearl Harbor on 7 December 1941. A Florida-class battleship, she was the only ship of the United States Navy to be named for the U.S. state of Utah. Prior to World War II, she had declined in usefulness and had been converted to a remotely controlled bombing target and gunnery target tow, redesignated AG-16. However, she was later refitted and rearmed and was in use for training purposes when sunk by a torpedo in the Japanese attack.
