Provisions were made for a new and more sturdy centerline pylon.

The leading edges of the underwing racks were moved further forward, their leading edges extending well forward of the wing leading edge. Improved and larger underwing bomb racks were installed. The dive brakes on the fuselage sides were deleted, but the ventral dive brake was retained. In order to accommodate the side-by side seating, the aircraft was lengthened by 1 feet 11 inches and the upper fuselage was broadened. The designation AD-5 was used instead for a December 1949 proposal for an aircraft which would combine the antisubmarine hunter-killer role in a single airframe and with side-by-side seating for two crew members. However, the turbocompound engine was so heavy and large that it would have required a major airframe redesign, and since the production run of the Skyraider was thought to be nearing its end, the project was not proceeded with. Several other aircraft of the era were also being considered for such an engine, including the B-36 and the B-50. The designation AD-5 was initially reserved for a proposed late-1948 version of the Skyraider to be powered by a turbo-compound version of the R-3350 engine.
