The Arkansas was the oldest battleship in the U.S. Navy at the start of the war, with a design going back to 1908. She would doubtless have already been scrapped but for the increase in international tensions in the late 1930s. She had been modernized with deck armor but was otherwise completely obsolete. She served most of the war in the Atlantic and was not committed to the Pacific until November 1944.

Arkansas' older sister, class namesake Wyoming, had been converted to a target ship before hostilities broke out, and she was not deemed worth converting back to a battleship.
