USS ''Missouri'', built by the New York Navy Yard, was commissioned on 11 June 1944. She spent the remainder of that year preparing for combat, transiting to the Pacific in November. Arriving in the war zone in January 1945, ''Missouri'' supported the Iwo Jima invasion, the Ryukyus campaign and raids on Japan's home islands during the following months. In May, she became Third Fleet flagship and was the site of the 2 September 1945 Japanese surrender ceremony that ended World War II.
