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 Space Force is playing midwife to a new ecosystem of commercial satellite constellations providing alternatives to the service’s own Global Positioning Service from much closer to the Earth, making their signals more accurate and harder to jam.
