"Cruiser Submarine Type # 1--Unprotected" ... October 20, 1920

Preliminary design plan for a "Cruiser Submarine" (Type # 1 -- Unprotected). The Chief of the Bureau of Construction and Repair requested in early October 1920 that his staff develop a set of comparative studies for ships of this type, apparently reflecting his desire to anticipate a possible need for large submarine scouts. The vessel was intended to carry heavy guns and scout aircraft, and be able to submerge "to great depths". Type # 1 emphasized gun armament and speed and had no protection and large aircraft storage tubes topside that the Bureau considered a risk to survival if flooded. The concept was not pursued.
This plan provided eight 8-inch guns, diesel machinery, and a surface speed of 14 knots in a ship 400 feet long on the waterline, 46 feet in beam, and with a normal surface displacement of 10,000 tons.
Note: The original document was ink on linen (black on white).

The original plan is in the 1911-1925 "Spring Styles Book".
