"10,000 Ton Treaty Displacement Airplane Carrier" ... January 15, 1925
Preliminary design plan for an aircraft carrier. This drawing represents one of a series of alternative designs undertaken during 1925-1926 to explore the capabilities possible in aircraft carriers ranging from 10,000 to 23,000 tons in an attempt to select the best balance between ship size and the number that could be built under the Washington Treaty's aggregate displacement limit. The calculations supporting this 10,000 ton design were recorded in Preliminary Design Book V-9, which document probably was discarded in the 1970s. No ship was built to this design.
This plan provides four 6-inch guns, turbine machinery, and a speed of 30 knots in a ship 600 feet long on the waterline, 72 feet in beam on the waterline, and with a displacement as defined by Washington Treaty provisions of 10,000 tons.
Note: The original document was ink on paper (black on white).
The original plan is in the 1911-1925 "Spring Styles Book".
