Title: "Preliminary Study # 3 ... Air Craft Carrier ... 34-3/4 knot", November 17, 1920 (lower half) Note:
Description: Photo #: S-584-168-B Preliminary Study # 3 ... Air Craft Carrier ... 34-3/4 knot, November 17, 1920 (lower half) Lower half of a preliminary design plan for an aircraft carrier for the Fiscal Year 1922 shipbuilding program (Preliminary Study # 3). This drawing was prepared by the Bureau of Construction and Repair in response to draft characteristics provided by the General Board on 6 November 1920 in order for the bureau to be able to discuss design tradeoffs at a planned General Board hearing. This version met all the draft characteristics save being one-quarter knot low on speed and having weak protection against torpedo attack. No ships were built to this concept, which was superseded by new designs in 1921 (see Photo # S-584-179.) This plan provided sixteen 6-inch guns, electric drive machinery, and a speed of 34.75 knots in a ship 840 feet long on the waterline, 80 feet in beam on the waterline, and with a normal displacement of 34,500 tons. The original document was ink on paper (black on white). The original plan is in the 1911-1925 Spring Styles Book. U.S. Naval History and Heritage Command Photograph.
