USS Missouri (BB-63)

USS Missouri (BB-63) is an Iowa-class battleship built for the United States Navy (USN) in the 1940s and is now a museum ship. Completed in 1944, she is the last battleship commissioned by the United States. The ship was assigned to the Pacific Theater during World War II, where she participated in the Battles of Iwo Jima and Okinawa and shelled the Japanese home islands. Her quarterdeck was the site where the Japanese Instrument of Surrender was signed, officially ending World War II.

After World War II, Missouri served in various diplomatic, show of force and training missions. In 1950, the ship ran aground during high tide in Chesapeake Bay and after great effort was re-floated several weeks later. She later fought in the Korean War during two tours between 1950 and 1953. Missouri was the first American battleship to arrive in Korean waters and served as the flagship for several admirals. The battleship took part in numerous shore bombardment operations and also served in a screening role for aircraft carriers. Missouri was decommissioned in 1955 and transferred to the reserve fleet (also known as the "Mothball Fleet").

Missouri was reactivated and modernized in 1984 as part of the 600-ship Navy plan. Cruise missile and anti-ship missile launchers were added along with updated electronics. The ship served in the Persian Gulf escorting oil tankers during threats from Iran, often while keeping her fire-control systems trained on land-based Iranian missile launchers. She served in Operation Desert Storm in 1991 including providing fire support.

Missouri was again decommissioned in 1992, but remained on the Naval Vessel Register until her name was struck in 1995. In 1998, she was donated to the USS Missouri Memorial Association and became a museum ship at Pearl Harbor, Hawaii.
