Naval History and Heritage Command

Washington, a 32,600-ton Colorado class battleship, was under construction at Camden, New Jersey, when the Washington naval limitations treaty was signed in February 1922. Launched in September 1921, the battleship was nearly 76 percent completed when construction ceased on 8 February 1922. Since the treaty prohibited her completion, Washington was subsequently used for tests of weapons effects and warship protection. Her hulk was sunk as a gunnery target in November 1924.
