Photo #: S-584-054 Preliminary Design No.116 for a Scout Cruiser ... April 1915 Preliminary design plan for a large scout cruiser, prepared to support General Board discussions concerning the characteristics sought in future cruisers. This plan provides ten 6-inch guns and a speed of 35 knots in a ship 740 feet long on the load water line, 65 feet in beam, with a normal displacement of 13,750 tons. Some 855 tons of armor was provided, including 4-inch side armor over 270 feet by 17 feet 6 inches amidships and 1.5-inch deck protection. This design was the first of a set of 11 designs undertaken as a group during 21 to 29 April 1915 to explore tradeoffs among armament, protection, and size in large scout cruisers capable of 35 knots speed. This design series took Preliminary Design No.112 (see Photo # S-584-050) as a baseline. Ultimately, however, no ships of this large type were built. Note: The original document was ink on linen (black on white). The original plan is in the 1911-1925 "Spring Styles Book". U.S. Naval Historical Center Photograph.
