The 355th Aircraft Generation Squadron (AGS) was a key maintenance unit assigned to the 355th Wing at Davis-Monthan Air Force Base, Arizona. Activated in the late 20th century, the squadron was responsible for maintaining, servicing, and generating combat-ready A-10 Thunderbolt II aircraft. The 355th AGS played a crucial role in supporting operations and deployments, ensuring aircraft were mission-ready for training and combat missions. In 2002, as part of an Air Force-wide reorganization, the squadron was inactivated and its functions were incorporated into newly structured Aircraft Maintenance Squadrons (AMXS).
