The fundamental building block for all future avionics software on the Lockheed Martin [NYSE: LMT] F-35 Lightning II stealth fighter has entered flight testing on an F-35 test jet. Block 1, the first of three principal software-development blocks for the F-35's mission systems, made its inaugural flight in the F-35B short takeoff/ vertical landing (STOVL) aircraft known as BF-4. The functional check flight from Naval Air Station Patuxent River lasted 1.5 hours, and all planned test points were accomplished.
