"USS Alabama (BB-60), a South Dakota-class battleship, was the sixth ship of the United States Navy named after the US state of Alabama. Alabama was commissioned in 1942 and served in World War II in the Atlantic and Pacific theaters. She was decommissioned in 1947 and assigned to the reserve duty. She was retired in 1962. In 1964, Alabama was taken to Mobile Bay and opened as a museum ship the following year. The ship was added to the National Historic Landmark registry in 1986."
