The largest aircraft boneyard in the WORLD!

Welcome to the largest aircraft boneyard in the WORLD!


The Boneyard is formally known as the 309th AMARG (Aerospace Maintenance And Regeneration Group).

An AMARG is a boneyard facility for all excess military and government aircraft.

Planes, jets, helicopters, and space shuttles belonging to the Air Force, Navy, Marine Corps, Coast Guard, and NASA are processed here.

The 309th AMARG is located at the Davis-Monthan Air Force Base in Tucson, Arizona.

This collection picked up steam after World War II.

550 people are currently employed to take care of the 4,400 aircraft that call this airfield their permanent residence.

When the aircraft first arrive at the 309th AMARG, they are welcomed by the receiving branch.

Next, the aircraft is stripped of firearms (all guns), ejection seat charges, clocks, and classified hardware.

The salt must be fully removed so it does not corrode the exterior while in storage.


The aircraft is finally sealed off from dust, high temperatures, and sunlight.

A variety of techniques are used, from spraylat (an opaque, white, high-tech vinyl plastic compound spray) to garbage bags.

The cabin will generally stay within 15 degrees of the outside temperature thanks to the spraylat.
