|Montana on the building ways at Mare Island Navy Yard, 3 January 1921 (Naval History and Heritage Command Photograph NH 74062)|
Authorized by Act of Congress of 29 August 1916 and appropriated-for on 4 March 1917, Montana (BB‑51) -- the third ship of the projected South Dakota (BB 49)‑class -- was laid down on 1 September 1920 at Vallejo, Calif., by the Mare Island Navy Yard.
In accordance with the stipulations of the Washington Treaty limiting naval armaments, however, Montana’s construction was suspended on 8 February 1922 when the ship was 27.6% complete. Stricken from the Navy list on 24 August 1923, she was sold on 25 October 1923 to the firm of Learner and Rosenthal, Oakland, Calif., and was broken up on the building ways.
