Nakhon Phanom RTAFB is located in Northeast Thailand by the Thai city of Nakhon Phanom, also known as NKP.  Detachment 3 of the 6994^th SS conducted operations at NKP between 4 April 1969 and 1 December 1972, when it relocated to Ubon RTAFB, Thailand.  NKP also hosted the Headquarters, 6994^th SS from 1 December 1972 until 28 January 1974 when it moved to Ubon RTAFB.

The detachment was specifically located at NKP to exclusively conduct missions in the Barrel Roll and Northern Steel Tiger mission areas in Laos under the codename Comando Forge.  Initially, there were only 3 aircraft and 144 airmen assigned to the detachment at NKP in April 1969, but by April 1970, there were 5 aircraft assigned to NKP.  The assigned strength of the squadron at NKP increased in January, February, and March 1973 to 180 airmen and 4 officers.  The increase in strength of the Squadron was due to the deactivation of Det 2, 6994^th Security Squadron at Danang AB, RVN in February 1973 with the reassignment of a large number of the Det 2 personnel to Nakhon Phanom.
