Title: "Cruiser Submarine Type # 2 -- Armored" ... October 23, 1920 Note:
Description: Photo #: S-584-166 Cruiser Submarine Type # 2 Armored ... October 23, 1920 Preliminary design plan for a Cruiser Submarine (Type # 2 Armored). 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 for transoceanic operations. Type # 2 incorporated 474 tons of armor protection but a bureau design report considered it very vulnerable to torpedo attack because it lacked the side protection system in Type # 3 (see Photo # S-584-165). The concept was not pursued. This plan provided eight 8-inch guns, diesel machinery, and a surface speed of 15.5 knots in a ship 490 feet long on the waterline, 60 feet in beam, and with a normal surface displacement of 13,500 tons. The original document was ink on linen (black on white). The original plan is in the 1911-1925 Spring Styles Book. U.S. Naval History and Heritage Command Photograph.
