Its primary mission was training for Fairchild A-10 Thunderbolt II and BGM-109G Gryphon crews. The 602d Tactical Control Wing moved to Davis-Monthan, and the division's training mission expanded to include Forward Air Controllers flying several aircraft. The BGM-109 mission ended with the signing of the Intermediate-Range Nuclear Forces Treaty. In 1989, division elements participated in Operation Just Cause. The division was inactivated with the implementation of the Objective Wing reorganization, which established a single wing on each Air Force Base.
