Preliminary Design No.117 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 800 feet long on the load water line, 70 feet in beam, with a normal displacement of 17,650 tons. Some 1830 tons of armor was provided, including 8-inch side armor over 296 feet by 17 feet 6 inches amidships and 3-inch deck protection. This design was second in 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".
