Preliminary Design No.113 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 32.5 knots in a ship 700 feet long on the load water line, 60 feet in beam, with a normal displacement of 10,500 tons. This design was adapted during early April 1915 from Preliminary Design No.112 (see Photo # S-584-050) by adding 732 tons of armor (including 4-inch side armor 192 feet x 20 feet 6 inches amidships and 1.5 inch deck protection) at the expense of 2.5 knots less speed but within the same displacement. Preliminary Designs # 113 to 115 were commissioned at the same time as an initial exploration of armament, speed, and protection options from the P.D. # 112 baseline. Ultimately, however, no ships of this 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".
