May 2nd, 2007 to Now

On May 2, 2007, AMARC was officially redesignated as the 309th Aerospace Maintenance and Regeneration Group (309th AMARG). This renaming was driven by an organizational restructuring within the Air Force Materiel Command (AFMC). The primary factors included aligning the facility under a numbered maintenance wing to streamline operations, enhance integration with enterprise-wide logistics, and improve efficiency in supporting global warfighter needs.

5/3/2007 - DAVIS-MONTHAN AIR FORCE BASE, Ariz. -- In an activation ceremony here May 2, the Aerospace Maintenance and Regeneration Center was officially redesignated as the 309th Aerospace Maintenance and Regeneration Group, under the 309th Maintenance Wing located at Hill Air Force Base, Utah.

As missions grew more diverse—handling intercontinental ballistic missiles, satellite components, and rapid aircraft regeneration—the change reflected a shift toward a more agile, high-tech industrial group. It also addressed evolving post-Cold War demands, such as treaty compliance for arms reduction, by centralizing expertise under unified command.The change of command was administrative, involving the deactivation of AMARC as a standalone center and its realignment as a group subordinate to the 309th Maintenance Wing at Hill Air Force Base, Utah.

This transfer placed AMARG under the Ogden Air Logistics Complex (attached in 2012), ensuring oversight from a specialized maintenance hub without relocating the physical site.
