The DoD Office of Inspector General plans to begin the subject evaluation on May 13, 2022. The objective of this evaluation is to determine whether the North Warning System (NWS) has the capability to detect and track current and emerging long-range air threats in the Arctic region. In addition, we will evaluate North American Aerospace Defense Command (NORAD) and U.S. Air Force plans to modernize or replace the NWS. We may revise or expand the objective and scope as the evaluation proceeds. We will also consider suggestions from management for additional or revised objectives.
