Building of a battleship to be named USS Montana (BB-67) in honor of the 41st state and to be the lead ship of her class was authorized July 19, 1940, and assigned to the Philadelphia Navy Yard; but, before her keel was laid, construction was canceled July 21, 1943. Montana was the second battleship and third ship overall to be given that name; however, both battleships (the other being BB-51) were cancelled. Only one Montana has ever been commissioned: ACR-13.
