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.
The rate of building B-21 bombers would speed up if the fiscal 2026 defense budget passes. But it remains unclear how much capacity would be added, and whether the Air Force would simply build the bombers faster, or buy more.
