Photo #: S-584-034 Proposed Battleship # 40 ... Design # 6--October 10, 1913 Preliminary design drawing for Battleship # 40, which was planned for construction in Fiscal Year 1915. This plan was one of five alternative designs presented to the Executive Committee of the Navy’s General Board on 10 October 1913. This design resembles that adopted for Battleship # 38 (see Photo # S-584-041) but differs in having three twin 16-inch turrets rather than four triple 14-inch turrets and in providing 17-inch side armor instead of the 13.5-inch armor in Battleship # 38. This plan provides six 16-inch guns, turbine machinery, and a speed of 21 knots in a ship 600 feet long on the load water line (L.W.L.), 94.0 feet in beam, with a normal displacement of 31,000 tons. Battleship # 40 ultimately was built to a design very similar to Battleship # 38, mounting twelve 14-inch guns. Note: The original document was ink on paper (black on white). The original plan is in the 1911-1925 "Spring Styles Book". U.S. Naval History and Heritage Command Photograph. Online Image: 281KB; 1550 x 1195 pixels
