Introduction: A Ship Forged in Steel and History
Few warships in history carry the weight of the USS Missouri (BB-63). Known affectionately as "Mighty Mo," this Iowa-class battleship served across three wars — World War II, the Korean War, and the Gulf War — and became the site of one of the most consequential moments in modern history: the formal surrender of Imperial Japan on September 2, 1945.

Construction and Commissioning
Laid down at the Brooklyn Navy Yard on January 6, 1941, USS Missouri was launched on January 29, 1944, and commissioned that June. She was the last battleship ever commissioned by the United States Navy — a distinction that adds to her legendary status. Her name honored the state of Missouri, home state of President Harry S. Truman, who would later witness history unfold on her decks.
Combat Service in the Pacific
Mighty Mo arrived in the Pacific in late 1944 and immediately joined some of the war's most intense operations. She participated in the following major engagements:
- Battle of Iwo Jima (1945): Provided naval gunfire support for Marine landings.
- Battle of Okinawa (1945): Sustained damage from a kamikaze strike — the dent is still visible on her hull today as a reminder of sacrifice.
- Carrier Task Force Escort: Protected fast carriers as part of the Third Fleet.
On April 11, 1945, a Japanese Zero kamikaze aircraft struck Missouri's starboard side. In a remarkable act of respect and naval tradition, the crew gave the young Japanese pilot a proper burial at sea.
The Surrender Ceremony: September 2, 1945
Missouri's most defining moment came in Tokyo Bay, where she hosted the formal surrender of Japan, ending World War II. Representatives of Japan signed the Instrument of Surrender on Missouri's teak deck, with General Douglas MacArthur presiding and representatives from the Allied nations bearing witness. The spot is still marked on the ship's deck today, preserved as a national monument.
Later Service: Korea and the Gulf War
Reactivated for the Korean War (1950–1953), Missouri provided critical naval gunfire support along the Korean coastline. After years in reserve, she was modernized in the 1980s under President Reagan's 600-ship Navy initiative, receiving Tomahawk cruise missiles, Harpoon anti-ship missiles, and Phalanx CIWS systems. She fired Tomahawks during Operation Desert Storm in 1991 — her final combat action.
Museum Ship and Legacy
Decommissioned in 1992, USS Missouri was donated to the USS Missouri Memorial Association and berthed at Pearl Harbor, Hawaii, in 1999 — adjacent to the USS Arizona Memorial, creating a powerful juxtaposition of where WWII in the Pacific began and ended. She is a National Historic Landmark and one of the most visited museum ships in the world.
Mighty Mo stands as a testament to American naval power, the courage of those who served aboard her, and the enduring importance of sea power in shaping history.
