At this time, we do know that the aircraft in question was being used to support the Radar Modernization Program (RMP), and its loss will have ramifications for that effort. The RMP has already suffered years of delays and major cost growth, the latter of which triggered a deep, legally mandated review. However, in the past year, the U.S. Air Force has been talking more positively about progress on this critical upgrade, as well as other parts of a larger B-52 modernization effort that have faced their own hurdles.
