An F-35 Lightning II has flown for the first time in the new Technology Refresh 3, or TR-3, configuration. TR-3 is intended to significantly upgrade the Lockheed Martin-built stealth fighter’s core processor, memory unit, and associated avionics so the platform can better support all of the new capabilities slated to equip the type under the upcoming Block 4 modernization program, which we now know includes a brand new radar.
