Northrop Grumman is now flight testing the advanced fire-control radar system for the F-35 Joint Strike Fighter. The active electronically scanned array radar—AN/APG-81—has checked out in top form against airborne and ground-based targets, stated a company news release. Northrop plans to deliver the first system to Lockheed Martin in Fort Worth, Tex., in November. There it will meet up with the other F-35 avionics for additional testing.
The KC-Z4, a blended wing body tanker concept being developed by startup JetZero, could fuel larger groups of aircraft at longer range to hold more targets at risk, company officials say.
