Letterkenny Army Depot

Letterkenny Army Depot (LEAD) is a United States Army facility located in Chambersburg, Pennsylvania in Franklin County.  The facility spans across 18,000 acres and is used to conduct maintenance, modification, storage, and demilitarization operations on tactical missiles and ammunition. Letterkenny has unique tactical missile repair capabilities for repairing a variety of Department of Defense (DoD) missile systems, including the MIM-104 PATRIOT missile and its ground support and radar equipment.  Letterkenny expanded its product line to include designation of the CITE for Power Generation for the Army, the overhaul of tactical wheeled vehicles (HMMWVs), material handling equipment (7.5-ton cranes), and Mobile Kitchen Trailers. In 2007, during the Iraq conflict, Letterkenny began building new Mine Resistant Ambush Protected (MRAP) armored vehicles in partnership with BAE Systems, and in 2010 was designated the Joint Depot Source of Repair (JDSOR) for Route Clearance Vehicles for the DoD.
