Arizona (BB-39) steaming in line ahead with at least four other battleships astern, in the 1920s.
Arizona alternately served as flagship for Battleship Divisions 2, 9 or 4. Based at San Pedro, during this period, Arizona operated with the fleet in the operating areas off the coast of southern California or in the Caribbean during fleet concentrations there. She participated in a succession of fleet problems (the annual maneuvers of the fleet that served as the culmination of the training year), ranging from the Caribbean to the waters off the west coast of central America and the Canal Zone; from the West Indies to the waters between Hawaii and the west coast.
