Photo #: S-584-009 "Battleships Nos. 36 & 37" ... November 13, 1911 Preliminary design plan for Battleships # 36 and # 37. 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. This drawing represents the final characteristics selected. The battleships Nevada (Battleship # 36) and Oklahoma (Battleship # 37) were built to this general design, and these ships were placed on contract for construction on 22 January 1912. This plan provides ten 14-inch guns, reciprocating steam machinery, and a speed of 20.5 knots in a ship 575 feet long on the load water line (L.W.L.), 95 feet in beam, with a normal displacement of 27,500 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.
