Preliminary Design No.121 for a Scout Cruiser ... May 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 720 feet long on the load water line, 65 feet in beam, with a normal displacement of 12,650 tons. This design included no armor, adding two heavy guns at the expense of 2,150 tons additional displacement over design No.112. This design was sixth in a set of 11 undertaken as a group during 21 to 29 April 1915 to explore tradeoffs among armament, protection, and size in such 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".
