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 Air Force may wind up buying land to build 120 new intercontinental ballistic missile silos as part of its revamped infrastructure approach for the new Sentinel ICBM.
