Furthermore, the surface is hard so that the aircraft do not sink into the ground.

In 1949, after the Air Force's creation as a separate service, the unit was redesignated as the 3040th Aircraft Storage Depot, and later 3040 Aircraft Storage Squadron. On 1 Jun 1956, the 3040 Aircraft Storage Squadron was discontinued. In 1965, the Military Aircraft Storage and Disposition Center was organized and tasked with processing aircraft for all the

Storage procedures
There are four categories of storage for aircraft at AMARG:
* Long Term (Type 1000) – Aircraft are kept intact in “inviolate” storage for future use. No parts are removed without the express permission of appropriate program office.
* Parts Reclamation (Type 2000) – Aircraft are kept, picked apart and used for spare part
A spare part, spare, service part, repair part, or replacement part, is an interchangeable part that is kept in an inventory and used for the repair or Refurbishment (electronics), refurbishment of defective equipment/units. Spare parts are an i ...
s.
* Flying Hold (Type 3000) – Aircraft are kept intact with regular running of their engines, towing to lubricate their bearings and servicing of fluids.
* Excess of DoD needs (Type 4000) – Aircraft are sold off whole or in parts.
AMARG employs approximately 500 DoD civil servants and 200 contractors.[309 AMARG Public Affairs] The facility is adjacent to the base. On average, AMARG annually returns approximately $500 million worth of spare parts to military, government, and allied customers. Congressional oversight determines what equipment may be sold to which customer.
An aircraft going into storage undergoes the following treatments:
* Ejection seat charges and classified hardware are removed.
* All aircraft are carefully washed with fresh water to remove environment residue and then allowed to dry.
* The fuel system is protected by draining it, refilling it with lightweight oil, running engines to coat fuel system plumbing and engines, and then draining it again. This leaves a protective oil film.
* The aircraft is sealed from dust, sunlight, and high temperatures. This is done using a variety of materials, including a high tech vinyl plastic compound that is sprayed on the aircraft. This compound is called ''Spraylat'' after its producer the Spraylat Corporation, and is applied in two coats, a black coat that seals the aircraft and a white coat that reflects the sun and helps to keep internal temperatures low. The plane is then towed by a tug to its designated "storage" position.
On average the Group annually receives 300 aircraft for storage and processes out about the same number (with 50 to 100 of those returning to flying service). Aircraft that fly again either return to the U.S. military, U.S. government agencies such as the U.S. Coast Guard, U.S. Forest Service

Accessibility
AMARG is a controlled-access site, and is off-limits to anyone not employed there without the proper clearance. From April 2013 onwards the base had hosted an annual 10K/5K run/walk which was open to the general public.
Use in film and TV production
AMARG has been used as a filming location in several films and television productions, despite security. The most recent and notable of these is '' Transformers: Revenge of the Fallen''. The exterior scenes of the Smithsonian set were actually filmed in the Boneyard.
