The AD-7 was the final production version of the Skyraider. It differed from the AD-6 in having an R-3350-26WB engine instead of a R-3350-26WA. It also had a strengthened undercarriage, more robust engine mountings, and stronger wing outer panels. Otherwise, it was much the same as the AD-6 which preceded it.
72 AD-7s were built, the last one leaving the production line on February 18, 1957. This brought Skyraider production to an end. A total of 3180 Skyraiders of all versions had been built. Two further batches of 84 AD-7 aircraft each were cancelled.
In September of 1962, surviving AD-7s were redesignated A-1J.
