Losing bidders have protested the U.S. Air Force’s contract award to Raytheon for the Three-Dimensional Expeditionary Long-Range Radar (3DELRR) program to replace the service’s primary ground-based aerial search radar. Northrop Grumman and Lockheed Martin filed protests with the Government Accountability Office (GAO) on October 21 and 22, respectively.
