Military Aircraft Storage and Disposition Center, David-Monthan AFB, Tucson, Arizona

The Military Aircraft Storage and Disposition Center (MASDC) was established in 1946 at Davis-Monthan Air Force Base in Tucson, Arizona, to store and manage surplus military aircraft after World War II. Its mission quickly expanded to include the preservation, reclamation, and disposal of aircraft from all U.S. military branches. The facility’s vast desert location, with its low humidity, provided ideal conditions to minimize corrosion and protect stored aircraft. Over the decades, MASDC evolved into what is now known as the 309th Aerospace Maintenance and Regeneration Group (AMARG), becoming the world’s largest aircraft boneyard and playing a critical role in fleet management, parts reclamation, and historic preservation.
