The squadron again replaced a unit controlled by a major command in 1969 when Tactical Air Command (TAC) activated it to replace the 4433d Air Transport Squadron at Dobbins AFB, Georgia.  The 4433d had been providing VIP transport, primarily for Army officers, under various designations since 1948.  The 4433d was originally organized as the 5th Special Air Missions Squadron under Bolling Field Command in the spring of 1948. on 19 July 1948 it became the 1115th Special Air Missions Squadron when Headquarters, USAF required units controlled by its major air commands to be numbered with four digits in assigned blocks of numbers.  In November 1952, the squadron was transferred to Continental Air Command, which required renumbering to the 2315th Air Transport Squadron, Light.  Transfer to TAC in July 1960 resulted in another designation, the 4433d Air Transport Squadron, Light, but the squadron mission remained the same.  TAC finally inactivated its VIP airlift squadrons, including the 13th, in 1970.
