"Heavy Armor Type Battleship"--Scheme "F" ... March 9, 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. It is believed that this preliminary design plan was used by the design team to evaluate the impact of sacrificing speed to retain heavy armor (as provided in Schemes "G" and "F") while trying, unsuccessfully, to stay within a 27,000-ton size limit. It is believed that this drawing was never sent to the General Board.
This plan provides eight 14-inch guns, reciprocating steam machinery, and a speed of 19 knots in a ship 615 feet long on the load water line (L.W.L.), 97 feet in beam, with a normal displacement of 30,200 tons.
Note: The original document was a blueprint (white on dark blue).
The original plan is in the 1911-1925 "Spring Styles Book".
