Gray Eagle unmanned aircraft systems await maintenance Aug. 12 in the recently opened Fort Hood Unmanned Aircraft System Maintenance Hangar at Robert Gray Army Airfield, West Fort Hood, Texas. The hangar was built to provide more space for the UAS and the Soldiers responsible for piloting and maintaining them. It also features three maintenance shops, two tool rooms and a technical supply area. The hangar easily houses six fully-assembled Gray Eagles on each side, with a taxiway down the middle to provide convenient maneuvering in and out of the hangar.
