For the rest of the 1920s, "Arizona"s service consisted of routine training exercises. Naval historian Paul Stillwell remarked that "the Pacific years included a great deal of sameness and repetition", and his chronology of the ship's movements is filled with phrases like "torpedo-defense practice", "battle-practice rehearsal", "gunnery practice", "en route to…", and "anchored at…". A recurring theme in these years were the annual Fleet Problems, which began in 1923 and simulated large fleet actions by having most of the active fleet face off against each other. The first two simulated an attack on the Panama Canal from the west, while in 1925 they attempted to defend the Hawaiian Islands. Other 1920s Fleet Problems included the Caribbean, near Central America, the West Indies, and Hawaii. On 27 July 1923 the ship, under command of John Y.R. Blakely, joined President Warren G. Harding's naval review in Seattle. Harding died just one week later, and "Arizona" joined the Pacific Fleet to fire a salute in his honor on 3 August.
