We plan to begin the subject evaluation in October 2022. The objective of this evaluation is to determine the extent to which the U.S. Air Force have implemented sustaining engineering actions to ensure that the Upgraded Early Warning Radar (UEWR) system is capable, reliable, and available to meet mission requirements while managing risks. We will also determine whether the program has addressed an open recommendation made in Report No.DODIG-2016-133, "Evaluation of the Integrated Tactical Warning/Attack Assessment Ground-Based Radars."
