USS Michigan (BB-27) was a South Carolina-class battleship and the second dreadnought built for the United States Navy. Laid down on December 17, 1906, at the New York Shipbuilding Corporation, she was launched on May 26, 1908, and commissioned on January 4, 1910. Measuring approximately 452 feet 9 inches (138 meters) in length with a beam of 80 feet 3 inches (24.4 meters) and a draft of 24 feet 6 inches (7.5 meters), Michigan displaced about 16,000 long tons (16,257 metric tons) at designed load, with a full load displacement reaching 17,617 long tons (17,900 metric tons). Powered by two-shaft vertical triple-expansion engines and twelve coal-fired Babcock & Wilcox boilers, she achieved a top speed of 18.5 knots (34 km/h; 21.2 mph) and had a cruising range of 5,000 nautical miles at 10 knots. Her armament comprised eight 12-inch (305 mm)/45 caliber Mark 5 guns in four twin superfiring turrets, and twenty-two 3-inch (76 mm)/50 guns in casemates along her sides. She was also equipped with two 21-inch (533 mm) submerged broadside torpedo tubes. The armor layout included a 12-inch (305 mm) belt over magazines, 10 inches (254 mm) over machinery spaces, and 8 inches (203 mm) elsewhere. Her gun turrets had 12-inch thick faces, supported by 10-inch thick barbettes and armor-protected casemates. Michigan served primarily in the Atlantic Fleet, conducting routine cruises along the U.S. east coast and the Caribbean. Notable service included participation in the U.S. occupation of Veracruz in 1914 during the Mexican Civil War. During World War I, she functioned as a convoy escort and training ship; however, her career was marred by a mast collapse in January 1918 that resulted in six fatalities. She also ferried soldiers back from Europe in 1919. Her operational life ended following the Washington Naval Treaty of 1922, which mandated her decommissioning and scrapping. She was decommissioned in February 1923 and dismantled in 1924, marking the end of her brief but significant contribution to early 20th-century naval history.
