She was then placed in reserve, recommissioning in May 1910 after a modernization that gave her a new "cage" mainmast. Atlantic Coast in early 1903 was followed by an overhaul and, from late 1903 until mid-1907, active service with the North Atlantic Fleet. She served along the West Coast until February 1902, when she began a year with the South Atlantic Squadron. In October of that year, a few months after the conflict's end, the battleship was sent around South America to join the Pacific Squadron. During the Spanish-American War Iowa served off Cuba and on 3 July 1898 played an important role in the Battle of Santiago, an action that destroyed Spain's naval power in the Western Hemisphere. She operated along the Atlantic seaboard for the rest of that year and into 1898. USS Iowa, a 11,410-ton battleship built at Philadelphia, Pennsylvania, was commissioned in June 1897.
