In the early 1980s, the South Carolina congressional delegation in Congress, led by Senators Strom Thurmond and Ernest Hollings, pressured the Department of Defense to upgrade Army and Air National Guard units with front line equipment to better supplement the Active Duty forces as part of the "Total Force" concept. Specifically, Thurmond and Hollings wanted the Air Force to equip the South Carolina ANG with the new F-16 Fighting Falcon, which was, as the time, just being introduced into the active duty force of Tactical Air Command. Beginning in July 1983, some of the initial Block 1 and Block 5 F-16As were transferred to the 169th Tactical Fighter Group, being the first Air National Guard unit to receive the aircraft. Its A-7Ds were subsequently reassigned to other Air National Guard units. Later, Block 10 F-16A/B were delivered by the Air Force to the 157th TFS. By the mid-eighties, all the F-16s received by the 169th had undergone Pacer Loft modification bringing them up to the same block 10 standards.
