Battleship Pennsylvania (Battleship # 38) ... November 21, 1913
Design plan for Pennsylvania (Battleship # 38). This design continued the concept of "all-or-nothing" armor protection introduced in the previous Nevada (Battleship # 36) class (see Photo S-584-009), 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 Pennsylvania (Battleship # 38) and Arizona (Battleship # 39) were built to this design. Pennsylvania was placed on contract for construction on 28 February 1913.
This plan provides twelve 14-inch guns, turbine machinery, and a speed of 21 knots in a ship 600 feet long on the load water line (L.W.L.), 97 feet 0-1/2 inches in beam, with a normal displacement of 31,400 tons.
Note: The original document was ink on linen (black on white).
The original plan is in the 1911-1925 "Spring Styles Book".
