Since its retirement from active flying status in 2008, the Air Force’s cadre of F-117 Nighthawks have been maintained at their original, climate-friendly hangars at the Tonopah Test Range Airport in Nevada. Given the cost of establishing secure storage facilities at Aircraft Maintenance and Regeneration Center (AMARC at Davis-Monthan AFB), the Air Force chose instead to store the retired F-117s at the pre-existing secure facilities at Tonopah Test Range.
Per Congressional direction within the FY07 National Defense Authorization Act the aircraft were placed in Type 1000, flyable storage for potential recall to future service. In order to confirm the effectiveness of the flyable storage program, some F-117 aircraft are occasionally flown."
