Preliminary Design No.122 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 provided two 14-inch guns and nine 5-inch guns and a speed of 35 knots in a ship 755 feet long on the load water line, 70 feet 6 inches in beam, with a normal displacement of 16,250 tons. This design included 935 tons of armor, 4-inch side armor over 296 feet by 17 feet 6 inches amidships plus 1.5-inch deck protection, adding 5,750 tons displacement over design No.112. This design was seventh in a set of 11 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 type were built.
Note: The original document was a blueprint (white on blue).
The original plan is in the 1911-1925 "Spring Styles Book".
