USS Wyoming (Monitor #10) was commissioned in December 1902 at Mare Island Naval Shipyard, Vallejo, California. After trials, the Arkansas-class monitor departed in 1903 for South America. Operating with the protected cruiser Boston in the spring of 1904 in Panamanian waters, she assisted and evacuated American lives during their civil war. Relocating to the West Coast, she served until decommissioned in August 1905. Converted to burn fuel oil, she was placed in and out of commission a few times until recommissioned in July 1910, then trained the Washington State Naval Militia. In the prior year, she was renamed Cheyenne to clear-up the name for USS Wyoming (Battleship #32).
Decommissioned again for a number of times, Cheyenne was converted to a submarine tender in February 1913 and assisted to embark refugees in April-May 1914 during the Intervention at Mexico. With United States entry into World War I, she relocated to assist submarines at various ports in Washington and California until joining the Atlantic Fleet, serving as flagship and tender for Division 3, Flotilla 1, Submarine Force, Atlantic Fleet. In this capacity, she was called to help American lives and property at Tampico, Mexico, in early 1919.
In January 1920, Cheyenne was decommissioned and became an inactive ship at Philadelphia, Pennsylvania. Recommissioned in September and redesignated as a miscellaneous auxiliary, IX-4, she relocated to Baltimore, Maryland, and trained Naval Reserve Force personnel until 1925. Decommissioned in June 1926, she was struck from the Naval Vessel Register in January 1937 and sold for scrapping two years later.
A model of the monitor when named Cheyenne is on display in the Great White Fleet exhibit at the National Museum of the U.S. Navy, Building 76.
