Army Expands Permissive UAV Test Network The U.S. Army has added the Camp Atterbury Joint Maneuver Training Center and the Muscatatok Training Center in Indiana to its initiative to expand its permissive test ranges for commercial and counter-UAV tests. Camp Atterbury offers 34,000+ acres and limited airspace up to 40,000 feet; Muscatotok provides a 1,000-acre urban-style developmental test site. The move expands supplier access to military ranges as the service pushes to shorten testing schedules for UAS and C-UAS systems. It also adds two distinct environments—open airspace and dense urban infrastructure—useful for verifying navigation, tracking, and interception performance under more operationally relevant conditions.
