The USS Wyoming (BM-10), originally laid down as Monitor No. 10, was an Arkansas-class coastal monitor commissioned by the United States Navy in December 1902. Displacing approximately 3,225 long tons, she measured 255 feet 1 inch in overall length, with a beam of 50 feet 1 inch and a draft of 12 feet 6 inches. Her hull was armored with up to 11 inches of belt armor amidships, tapering to 5 inches at the ends, and her gun turrets were protected by armor ranging from 9 to 10 inches. The vessel was powered by two vertical triple-expansion engines generating about 2,336 indicated horsepower, driving two screw propellers, and she was capable of reaching a top speed of approximately 12.4 knots. The USS Wyoming was notable for being the first U.S. Navy ship converted to oil power, making her a pioneering vessel in fuel technology. Her armament included two 12-inch/40 caliber main guns housed in a single turret, supported by four 4-inch/50 caliber secondary guns and three 6-pounder guns, offering significant firepower for her size. She also carried a deck armor of 1.5 inches. Her early service included trials and exercises along the California coast before deploying to Central America and Panama during regional unrest, notably participating in observing events surrounding Panama's independence from Colombia. Throughout her service, Wyoming operated along the West Coast, participated in local regattas, and supported American interests in Panama and Mexico. She was renamed Cheyenne in 1909 to free the name for a new battleship and underwent several modifications, including conversion into a submarine tender in 1913. During World War I, Cheyenne served as a flagship and tender for submarine divisions, operating along the U.S. West Coast and in the Atlantic, including Tampico, Mexico, and later in training roles. After the war, she was classified as a miscellaneous auxiliary (IX-4) and served with the Naval Reserve Force until her decommissioning in 1926. Ultimately sold for scrap in 1939, USS Wyoming/Cheyenne played a versatile role in early 20th-century naval operations, especially noted for her pioneering oil conversion and service in regional conflicts and training.
