46cm/45 type 94 naval gun (deleted)

The Imperial Japanese 46 cm/45 Type 94 naval gun (四十五口径九四式四〇糎砲, Yonjūgo-kōkei kyūyon-shiki yonjussenchi-hō) was a 46 cm (18.1 in) naval rifle, the largest ever mounted on a warship, carried them only two battleships during World War II, the Yamato and Musashi. They were designated as a much smaller 40 cm (15.7 in) gun in an effort to hide their true size.
