The Joint Strike Fighter began the integration phase of weapons testing Oct. 26 when the F-35A Conventional Takeoff and Landing (CTOL) aircraft successfully completed the first in-flight test with an AIM-120 Advanced Medium Range Air-to-Air Missile. It was the first time a weapon communicated with the aircraft during flight using a data link. (Courtesy photo by Matthew Short/Lockheed Martin)
