The USS Missouri was built at the Brooklyn New York Navy shipyard and launched on January 29, 1944. Miss Margaret Truman; daughter of then Vice President Harry S. Truman, performed the honor of launching the ship. The Missouri is 887 feet long and had a top speed of 30 knots. The ship's three 16-inch gun batteries were capable of firing artillery shells up to 23 miles and were mainly used for shore bombardment. Following a refit in the 1980s the Missouri was also able to fire Tomahawk cruise missiles.
During World War II, the Missouri saw action in the Pacific Theater at the battles of Iwo Jima and Okinawa, among others. The formal Japanese surrender that officially ended World War II was signed on her decks by General Douglas MacArthur and Japanese Foreign Minister Mamoru Shigemitsu on 2 September 1945. The Missouri next saw combat during the Korean conflict of the 1950s. The first American battleship to reach Korean waters, she bombarded Samchok on 15 September 1950 in an attempt to divert troops and attention from the Incheon landings. This was the first time since World War II that Missouri had fired her guns in anger, and in company with the cruiser Helena and two destroyers, she helped prepare the way for the U.S. Eighth Army offensive on the Korean peninsula.
After the Korean war the Missouri was placed in the reserve fleet. The ship was reactivated as part of President Ronald Reagan's effort to expand the Navy. The USS Missouri was involved in supporting coalition forces led by the United States against Saddam Hussein's Iraqi forces. As part of Operation Desert Storm, crews aboard the Missouri launched Tomahawk missiles at Iraqi targets from January 17-21, 199. The Missouri moved northward in the Persian Gulf following these missile launches, using advanced mine-avoidance sonar. Crews aboard the USS Missouri shelled an Iraqi command and control bunker near the Saudi border. This action marked the first time the ship's 16-inch guns had been fired in combat since the Korean War. The battleship bombarded Iraqi beach defenses in occupied Kuwait on the night of 3 February, firing 112 16 inch rounds over the next three days until relieved by her sister ship the USS Wisconsin.
The USS Missouri was decommissioned in 1995. The USS Missouri received eight battle stars for her service in World War II, five for her service during the Korean War, and three for her service during the Gulf War. Since 1998, the Mighty Mo has been moored at Pearl Harbor, Hawaii as a floating museum ship. Her bow points toward the memorial to the USS Arizona; sunk during the surprise Japanese attack in 1941.
