Missouri (BB-63) was the third and final completed Iowa-class battleship commissioned into the United States Navy during World War II. She is best known for hosting the Japanese Instrument of Surrender on her deck in Tokyo Bay and for later service in the Korean War, Vietnam War, and Gulf War before becoming a museum ship at Pearl Harbor adjacent to USS Arizona (BB-39). Missouri combined heavy firepower, high speed, and postwar upgrades that linked her to figures and events including Admiral William Halsey Jr., General Douglas MacArthur, Fleet Admiral Chester W. Nimitz, and operations involving Task Force 58, Task Force 77, and Operation Desert Storm.

Design and construction

Missouri was ordered as part of an expansion driven by the Naval Act of 1938 and designed alongside sister ships USS Iowa (BB-61), USS New Jersey (BB-62), and USS Wisconsin (BB-64) to counter Imperial Japanese Navy capital ships and to operate with Fast Carrier Task Force elements such as USS Enterprise (CV-6), USS Lexington (CV-16), and USS Franklin (CV-13). Her hull and machinery emphasized speed comparable to carrier formations commanded by officers like Admiral Raymond A. Spruance and protection derived from Washington Naval Treaty lessons examined by General Board (US Navy). Built at New York Naval Shipyard under Superintendent Rear Admiral Harold G. Bowen Sr., Missouri's armor scheme, main battery of 9 × 16 in/50 cal guns supplied by contractors tied to Bethlehem Steel and Westinghouse Electric Corporation, and secondary armament reflected industrial networks including New York Shipbuilding Corporation suppliers and wartime procurement overseen by Franklin D. Roosevelt administration agencies.

World War II service

Commissioned under Captain Charles B. Momsen, Missouri joined Pacific Fleet operations and screened Fast Carrier Task Force units including Task Force 58 during strikes on Guadalcanal, Saipan, and the Philippines campaign (1944–45), linking actions with admirals Marc Mitscher and William Halsey Jr.. Missouri provided naval gunfire support during the Battle of Iwo Jima and Okinawa campaign (1945), engaged in shore bombardment supporting commanders such as Admiral Richmond K. Turner and Lieutenant General Simon Bolivar Buckner Jr.. In Tokyo Bay on 2 September 1945, Missouri hosted the surrender ceremony attended by General Douglas MacArthur, Fleet Admiral Chester W. Nimitz, Foreign Minister Mamoru Shigemitsu, and delegations from United Kingdom, Soviet Union, Republic of China, and Commonwealth of Nations, marking the formal end of hostilities in the Pacific.

Korean War and Cold War modernizations

Reactivated for the Korean War under pressure from United States Congress and the Department of Defense, Missouri provided heavy naval gunfire escort for United Nations Command amphibious operations linked to commanders like General Douglas MacArthur and Admiral Arthur D. Struble. Postwar years saw periods in reserve and modernization studies influenced by thinkers such as Hyman Rickover and policy debates in National Security Council meetings; proposals included conversion concepts discussed with Secretary of the Navy offices and Congressional Budget Office staff. In the 1980s, defense initiatives under President Ronald Reagan and the 600-ship Navy program led to extensive overhaul at Long Beach Naval Shipyard and Brooklyn Navy Yard including addition of modern electronics tied to firms like Raytheon, integration with Aegis Combat System doctrines, and updates to communications linking Missouri to carrier groups such as USS Carl Vinson (CVN-70).

Vietnam, 1980s reactivation, and Operation Desert Storm

During the Vietnam War Missouri conducted shore bombardment and naval gunfire missions coordinated with III Marine Amphibious Force and commanders such as General Creighton Abrams. Reactivated and recommissioned in 1986 amidst Reagan administration naval expansion, Missouri participated in training and deployments including NATO and Operation Earnest Will escort planning with US Sixth Fleet ships like USS Coral Sea (CV-43). In 1991 Missouri supported Operation Desert Storm naval strikes in the Gulf War for Operation Desert Shield and Operation Desert Storm alongside USS Midway (CV-41), USS Wisconsin (BB-64), Royal Navy units, and coalition partners under General Norman Schwarzkopf Jr., employing 16-inch battery fire missions and cruise missile coordination involving Tomahawk planners.

Decommissioning and museum ship

Following final decommissioning in 1992 under Secretary of the Navy John H. Dalton and Chief of Naval Operations advisement, Missouri was transferred for preservation through efforts by organizations including the USS Missouri Memorial Association, City of Honolulu, and USS Arizona Memorial stakeholders. She was towed to Pearl Harbor and opened as a museum ship alongside USS Arizona (BB-39) and located at Ford Island, interpreted by curators referencing artifacts associated with figures like Admiral William F. Halsey Jr. and General MacArthur. Conservation work has involved partnerships with National Park Service, Hawaiʻi State Department of Land and Natural Resources, and contractors experienced with Historic American Engineering Record protocols.

Legacy and honors

Missouri's legacy is preserved through displays and commemorations by institutions such as the Naval History and Heritage Command, Smithsonian Institution collaborations, and veteran organizations including Veterans of Foreign Wars and American Legion. Honors associated with Missouri include campaign ribbons for World War II, Korean War, Vietnam War, and Gulf War campaigns, battle stars recognized by Department of the Navy citation procedures, and appearances in popular culture connected to filmmakers like Steven Spielberg and publications from Naval Institute Press. The ship remains a focal point for public history linking the surrender in Tokyo Bay to later 20th-century conflicts involving leaders such as Ronald Reagan, George H. W. Bush, and military planners from CENTCOM.
