Photo #: S-511-41 CV-D - Aircraft Carrier Preliminary design plan prepared for the General Board during the process that led to the armored flight deck Midway (CVB-41) class. This plan, dated 12 July 1941, depicts a 28,000-ton (standard displacement) 788-foot (between perpendiculars) ship with 1.5-inch flight deck armor and all aircraft elevators on the port side. Gun battery contains twelve 5/38 dual-purpose guns (four twin mounts and four singles). This ship, whose displacement approximated that of the Essex (CV-9) class, was too small to operate a full-sized air group. Scale of the original drawings is 1/32 = 1'. The original plan is in the 1939-1944 Spring Styles Book held by the Naval History and Heritage Command. U.S. Naval History and Heritage Command Photograph.
