An F-35A Lightning II fighter jet assigned to the 421st Fighter Squadron, Hill Air Force Base, Utah, takes off during Red Flag 20-1 at Nellis AFB, Nevada, Feb. 5, 2020. A recent ground test conducted at Nellis proved that Air Force personnel could safely and securely take data output from a flight test instrumentation system and convert the F-35’s data to communicate with mobile applications running on a connected commercial tablet. The test was part of the Fighter Optimization eXperiment (FoX), a project that seeks to rapidly integrate advanced software and hardware technologies to maximize the F-35’s lethality and survivability, while creating an agile development test tool and fielded combat multiplier for all DoD aircraft.
