Design and development

The Model 493-3-2 was similar to the baseline C-97 Stratofreighter but differed in having a gull-wing and increased wingspan, but also turboprop engines. The wingspan measured 165 feet from tip to tip, and the fuselage diameter was increased to 214 inches to accommodate a second deck as on the Douglas C-124 Globemaster II.[1][2][3]

Although a promising design, the Model 493 never left the drawboard because of the USAF's announcement of the XC-Heavy competition based on the concept of pod-equipped airlifter.[1]

The Model 493-3-2 is known in some sources as the C-127, but Air Force records show that the C-127 designator was allocated to the Douglas C-124B.[1][3]
