Preliminary Design Plan for a Battleship ... December 11, 1916
A preliminary design plan (Scheme 2) 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 2 differed from Scheme 1 (see Photo # S-584- 104) in housing the 5-inch secondary battery in casemates rather than in turrets.
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".
