The Boneyard 75th Anniversary

The first predecessor of the 309th AMARG was established in 1946 as the 4105th Army Air Forces Base Unit (Aircraft Storage) to house Boeing B-29 Superfortress and Douglas C-47 Skytrain aircraft.Davis–Monthan Field was chosen because of Tucson's low humidity, infrequent rainfall, alkaline soil and high altitude of 2,550 feet (780 m), reducing rust and corrosion.The hard soil makes it possible to move aircraft around without having to pave the storage areas.
