Northrop Grumman announced Tuesday that its industry team has completed the system development and demonstration phase of the program to modernize the radars on the Air Force’s B-2A stealth bombers. “The completion of SDD adds momentum and confidence to our work equipping the B-2 fleet with the most modern radar technology,” said Dave Mazur, Northrop’s B-2 program manager. SDD included installing the new Raytheon-supplied radar gear, including advanced electronically scanned array antennas, on the B-2 test aircraft and first group of operational B-2s as well as delivering the spare parts for them. The program is now in its full-rate production phase, with installation of the new gear on all 20 B-2s expected to be complete in 2012, according to Northrop.
Depot-level maintenance took longer than expected for nearly three-quarters of Air Force aircraft from fiscal 2019-2024, according to a new report, as unplanned repairs rise across the aging fleet. The report, from the Government Accountability Office, also found that the extent of the delays has been masked because officials often revise their target timelines after unplanned work occurs.
