USS Maine (BB-10), the lead ship of her class of pre-dreadnought battleships, was the second ship of the United States Navy to be named in honor of the 23rd state. Maine was laid down in February 1899 at the William Cramp & Sons shipyard in Philadelphia. She was launched in July 1901 and commissioned into the fleet in December 1902. She was armed with a main battery of four 12-inch (305 mm) guns and could steam at a top speed of 18 knots (33 km/h; 21 mph).
Maine served in the Atlantic for the entirety of her career with the North Atlantic Fleet, which later became the Atlantic Fleet; during the early years of her service, she was the fleet flagship, until she was replaced in 1907. Later that year, she joined the cruise of the Great White Fleet, though her heavy coal consumption prevented her from continuing with the fleet past San Francisco. After returning to the U.S., she served as the 3rd Squadron flagship. During America's participation in World War I from April 1917 to November 1918, Maine was used as a training ship. She remained in active service until May 1920, when she was decommissioned. The ship was ultimately sold for scrap in January 1922 and broken up for scrap under the terms of the Washington Naval Treaty signed that year.  wiki
