The aircraft “boneyard” at Davis-Monthan Air Force Base is getting a massive new place to work on resurrecting old military planes.

The U.S. Air Force 309th Aerospace Maintenance and Regeneration Group is building a massive new hangar at D-M in a $25 million project that includes supporting shops, storage and office s.

Expected to open in February, the new hangar will support maintenance, repair and inspection for the regeneration and reclamation of C-130, KC-135, and P-3 aircraft, for sales to allied air forces or use by the Pentagon or other federal and state agencies, AMARG officials said.

At 310 feet long with a 52-foot clear overhead height, the 76,746-square-foot hangar will accommodate two C-130 or KC-135 cargo aircraft.

The hangar will be a “high-visibility flagship” facility, accommodating VIP visitors in a two-story administration section with an overlooking observation deck, AMARG officials said.

Established in 1946 to store vast numbers of surplus World War II aircraft, the AMARG center is home to more than 4,000 planes.
