Photo #: S-584-005 "Proposed B. S. [Battleship] # 36"--Scheme "C" ... March 11, 1911 Preliminary design plan for Battleship # 36. This design incorporated the new concept of "all-or-nothing" armor protection, reducing the area protected by armor but increasing the thickness of armor significantly where it was provided, such as the main side belt and on the turrets. The General Board recommended on 30 March 1911 to the Secretary of the Navy that this particular plan be adopted for construction of the next battleships. The Secretary of the Navy approved that recommendation the following day and Nevada (Battleship # 36) and Oklahoma (Battleship # 37) were built to this design concept (see Photo # S-584-009). This plan provides ten 14-inch guns, reciprocating steam machinery, and a speed of 20.5 knots in a ship 565 feet long on the load water line (L.W.L.), 95 feet in beam, with a normal displacement of 27,000 tons. Note: The original document was a blueprint (white on dark blue). The original plan is in the 1911-1925 "Spring Styles Book". U.S. Naval History and Heritage Command Photograph.
