Northrop Grumman said in a release July 3 it successfully demonstrated electronic protection capabilities of the AN/APG-81 advanced electronically scanned array radar system during the recent Northern Edge joint military exercise. The radar, which the company is building for the F-35 stealth fighter, was on board a company testbed aircraft during a complex airborne electronic warfare drill and countered advanced electronic attacks intended to degrade, neutralize, or destroy its capability, according to the company. “This event represents a major milestone in electronic protection testing for the AN/APG-81 in an operationally representative environment.” said Teri Marconi, Northrop’s vice president of Combat Avionics. The APG-81 is currently undergoing flight testing aboard Lockheed Martin’s F-35 avionics testbed aircraft, the CATBird, and is being installed in production F-35s on Lockheed’s aircraft assembly line in Fort Worth, Tex.
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.
