The F-35 performed so dismally in a dogfight, that the test pilot remarked that the it had pretty much no place fighting other aircraft within visual range.

And it's even worse than a mere maneuverability issue. At one point, the pilot's helmet was so big he couldn't even turn his head inside the cockpit.

That's according to a scathing report obtained by our friends over at War Is Boring that details the results of visual range air-to-air engagement tests between an F-35A and an F-16C. The F-35, which the US Air Force, Navy, and Marines are expected to rely upon, in addition to the air arms of militaries across the world for at least the next few decades, was supposed to be better than its F-16 predecessor in all respects.
