dismantling or reuse in satellite launches, and was renamed the Aerospace Maintenance and Regeneration Center (AMARC) to reflect the expanded focus on all aerospace assets. In the 1990s, in accordance with the START I treaty, the center was tasked with eliminating 365 Boeing B-52 Stratofortress bombers. The progress of this task was to be verified by Russia via satellite and first-person inspection at the facility. Initially, the B-52s were chopped into pieces with a 13,000 pound guillotine winched by a steel cable supported by a crane. Later on, the tool of choice became K-12 rescue saws. This more precise technique afforded AMARC with salvageable spare parts. In May 2007, the AMARC was transferred to the 309th Maintenance Wing, and the center was renamed the 309th Aerospace Maintenance and Regeneration Group (AMARG).

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 parts Flying Hold (Type 3000) – Aircraft are kept intact with regular running of their engines, towing to lubricate their bearings and servicing of fluids.
