The 309th Aerospace Maintenance and Regeneration Group (309 AMARG) is a one-of-a-kind specialized
facility within the Air Force Materiel Command structure. 309 AMARG provides critical aerospace
maintenance and regeneration capabilities for Joint and Allied/Coalition war fighters in support of
global operations and agile combat support for a wide range of military operations.

Immediately after World War II, the Army's San Antonio Air Technical Service Command established a
storage facility for B-29 and C-47 aircraft at Davis-Monthan AFB. Today, this facility is the 309th
Aerospace Maintenance and Regeneration Group (309 AMARG), which has grown to include more than 4,400
aircraft and 13 aerospace vehicles from the Air Force, Navy-Marine Corps, Army, Coast Guard, and
several federal agencies including NASA. More Information. (US Air Force)
