Located in an isolated area west of Boardman, Oregon, the Boardman RCS range is owned and operated by Boeing. The facility consists of a radar array at the west end and a pylon for mounting test articles at the east end. The pylon can be covered by a large, moveable hangar, to protect sensitive test objects from view. When RCS testing is ongoing, the hangar slides out of the field of view of the radar sensors on a set of rails. The sliding shelter concept is similar to what was used at the former Grey Butte RCS test range.
