|The 309th Aerospace Maintenance and Regeneration Group (AMARG), often called The Boneyard, is a United States Air Force aircraft and missile storage and maintenance facility in Tucson, Arizona. |
AMARG takes care of more than 4,400 aircraft, which makes it the largest aircraft storage and preservation facility in the world.
The hard soil makes it possible to move aircraft around without having to pave the storage areas.
|AMARG was established in 1946 as the 4105th Army Air Force Unit to house B-29 and C-47 aircraft. Davis-Monthan Air Force Base was chosen because of Tucson's low humidity, infrequent rainfall, alkaline soil and high altitude of 2,550 feet, reducing rust and corrosion.|
