The AD-4N was a three-seat night attack version of the AD-4. 307 examples were built. A searchlight was carried on the port underwing pylon, and a radar installation was installed on the starboard underwing pylon. However, most of these aircraft were either delivered as AD-4S anti-submarine search aircraft or were converted in the field as AD-4S.
In addition, 100 became AD-4NAs (BuNos 125742/125764, 136876/126883, 126903/126925/ 126947/126969, and 126988/127010) which were stripped of all night attack gear which made them capable of carrying heavier bombloads for Korean operations. Wing mounted armament was increased to four 20- mm cannon. The AD-4NA was redesignated A-1D in September 1962.
Following modification by Douglas on AD-4N Bu No 124153 which was fitted with anti-icing and deicing equipment, 36
AD-4Ns (BuNos 124725/124760) were so modified in service. The wing-mounted armament was increased to four 20-mm cannon. When so
modified, these planes were redesignated AD-4NL.
