Battleship USS Idaho fitting out at New York Ship Building Corporation, June 23rd 1919.

Note the lack of hull-mounted secondary armament. According to navsource.org, she was the first battleship to be completed without such guns as their ports were plated over before her commissioning; however, the emplacements remained as her hull was otherwise like that of her sister ships.
