|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.
|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.|
The hard soil makes it possible to move aircraft around without having to pave the storage areas.
