AF
3556th Maintenance
U.S. Air Force
The 3556th Maintenance Squadron was a United States Air Force unit activated at Perrin Air Force Base, Texas, during the mid-20th century. Its primary mission was to provide aircraft maintenance and logistical support for the flying training missions conducted at the base, particularly for jet interceptors such as the F-86 Sabre and T-33 Shooting Star. The squadron played a critical role in ensuring aircraft readiness and operational efficiency, supporting both pilot training and air defense missions during the Cold War era. The unit was eventually inactivated as part of the broader drawdown and closure of Perrin AFB in 1971.
