 Preliminary Design Plan for a Battleship ... December 11, 1916
 
 A preliminary design plan (Scheme 1) for a battleship to be funded
    in Fiscal Year 1918, sent on 21 December 1916 to the General
    Board. This design followed the Colorado (Battleship #
    45) class in layout but incorporated triple 16-inch/50-caliber
    gun turrets in place of twin 16- inch/45-caliber turrets. A significant
    increase in length was necessary to incorporate desired characteristics.
    This design series was the origin of development of the South
    Dakota (Battleship # 49) class design. Scheme 1 differed
    from earlier battleship designs in housing the 5-inch secondary
    battery in turrets rather than in casemate mountings.
 This plan provided twelve 16-inch guns, electric drive machinery,
    and a speed of 23 knots in a ship 660 feet long on the waterline,
    105 feet in beam, and with a normal displacement of 41,500 tons.
 Note: The original document was a blueprint (white on
    dark blue).
 
 The original plan is in the 1911-1925 "Spring Styles Book".
