The second F-35 Lightning II production aircraft, AF-7, has taken off from Naval Air Station Fort Worth Joint Reserve Base, making its first flight last Friday (March 4).
The F-35A CTOL variant flew for 1.3 hours. AF-7 is the second and final aircraft from Low Rate Initial Production (LRIP) lot 1, with the first aircraft, AF-6, flying for the first time a week earlier on February 25.
The two production jets and eleven preproduction F-35 test aircraft have completed 683 flights since testing began in December 2006.
