USS Missouri (BB-63) ("Mighty Mo" or "Big Mo") is a U.S. Navy battleship, and was the third ship of the United States Navy to be named in honor of the U.S. state of Missouri. Missouri is the final battleship to be built by the United States, and among the Iowa-class battleships is notable for being the site of the surrender of the Empire of Japan at the end of World War II. Missouri
was ordered on 12 June 1940 and her keel was laid at the New York Navy Yard in the New York City borough of Brooklyn on 6 January 1941.
During her career Missouri saw action in World War II during the Battle of Iwo Jima and the Battle of Okinawa, and shelled the Japanese home islands of Hokkaidō and Honshū. After World War II she returned to the United States before being called up and dispatched to fight in the Korean War. Upon her return to the United States she was decommissioned into the United States Navy reserve fleets, better known as the "Mothball Fleet" in 1955. She was reactivated and modernized in 1984 as part of the 600-ship Navy plan, and participated in the 1991 Gulf War.
Missouri was decommissioned a final time on 31 March 1992, having received a total of eleven battle stars for service in World War II, Korea, and the Persian Gulf. She was maintained on the Naval Vessel Register until January 1995, when her name was struck. In 1998 she was donated to the Missouri Memorial Association, and is presently a museum ship at Pearl Harbor, Hawaii.
American and British sailors and officers watch General of the Army Douglas MacArthur sign documents during the surrender ceremony aboard Missouri on 2 September 1945. The unconditional surrender of the Japanese to the Allies officially ended the Second World War.
