Preliminary Design No.120 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 four 12-inch guns and seven 5-inch guns and a speed of 35 knots in a ship 800 feet long on the load water line, 80 feet in beam, with a normal displacement of 22,850 tons. This design included 2,175 tons of armor, 8-inch side armor over 348 feet by 17 feet 6 inches amidships plus 3-inch deck protection, adding 12,350 tons displacement over design No.112. This design was fifth in a set of 11 undertaken as a group 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".
