"The Department of Defense (DOD) uses its maintenance capabilities to maintain, overhaul, and repair its military weapon systems (such as aircraft and ships) and equipment (such as generators and radars). To maintain these systems and equipment in order to meet national security goals, DOD uses a combination of military depots-public-sector facilities that are government-owned and government-operated-and private-sector contractors. Depots have a key role in sustaining complex weapon systems and equipment both in peacetime and during mobilization, contingency, or other emergency. The military services operate 17 primary government-owned facilities-such as Anniston Army Depot at Anniston, Alabama; Air Force's Air Logistic Complex at Ogden, Utah; Norfolk Naval Shipyard at Portsmouth, Virginia; and Marine Depot Maintenance Command at Albany, Georgia-that perform depot-level maintenance on a wide range of vehicles and other military assets, including helicopters, combat vehicles, ships, aircraft, engines, and software. […] We conducted this performance audit from May 2015 to February 2017 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings based on our audit objectives."
