The USS Colorado (BB-45) was a Colorado-class battleship of the United States Navy, commissioned in 1923 and serving until 1947. As the lead ship of her class, she was a formidable capital vessel, measuring 624 feet in length overall with a beam of 97 feet 6 inches and a draft of 30 feet 6 inches. She displaced approximately 32,693 long tons at standard load, rising to about 33,590 long tons at full load. Her propulsion system consisted of four General Electric turbo-electric drives powered by eight oil-fired Babcock & Wilcox boilers, which allowed her to reach a top speed of just over 21 knots, with a cruising range of up to 8,000 nautical miles at 10 knots, extendable to over 21,000 nautical miles with additional fuel. Her armament comprised eight 16-inch (406 mm) /45 caliber Mark 1 guns mounted in four twin turrets, and fourteen 5-inch (127 mm) /51 caliber guns, with some modifications during her service to enhance anti-aircraft defenses by replacing her 3-inch guns with 5-inch/25 caliber guns. She also carried a secondary battery of sixteen 5-inch guns and an anti-aircraft battery of eight 3-inch guns. Her armor protection included an 8–13.5 inch thick belt, an armored deck up to 3.5 inches thick, and heavily armored gun turrets with 18 inches of face armor. Constructed by the New York Shipbuilding Corporation, her keel was laid in 1919, and she was launched in 1921. She initially operated in European waters and the Pacific, participating in fleet exercises, diplomatic visits, and naval reviews. During the interwar years, she underwent overhauls to modernize her anti-aircraft armament and participated in various training missions. During World War II, USS Colorado played a key role in Pacific theater operations. She conducted patrols near San Francisco early in the war and supported amphibious landings at Tarawa, the Marshalls, Saipan, Guam, and Tinian. Notably, she sustained 22 shell hits during the Tinian operation but continued shelling shore positions. She was also damaged by kamikaze attacks at Leyte Gulf, with 19 crewmen killed and 72 wounded. Later, she participated in bombardments at Lingayen Gulf and Okinawa, providing crucial fire support. After the war, she helped in occupation duties in Japan before being decommissioned in 1947. She earned seven battle stars for her wartime service. Her legacy includes numerous artifacts, such as her ship's bell, helm, and deck guns, some of which are displayed in museums and institutions across Colorado and the Pacific Northwest. Her service history underscores her significance as a key component of the U.S. Navy's battleship force during both the interwar period and World War II.
