The F-35 was flying “clean,” with no weapons in its bomb bay or under its wings and fuselage. The F-16, by contrast, was hauling two bulky underwing drop tanks, putting the older jet at an aerodynamic disadvantage.
But the JSF’s advantage didn’t actually help in the end. The stealth fighter proved too sluggish to reliably defeat the F-16, even with the F-16 lugging extra fuel tanks. “Even with the limited F-16 target configuration, the F-35A remained at a distinct energy disadvantage for every engagement,” the pilot reported.

The F-35 jockey tried to target the F-16 with the stealth jet’s 25-millimeter cannon, but the smaller F-16 easily dodged. “Instead of catching the bandit off-guard by rapidly pull aft to achieve lead, the nose rate was slow, allowing him to easily time his jink prior to a gun solution,” the JSF pilot complained.
And when the pilot of the F-16 turned the tables on the F-35, maneuvering to put the stealth plane in his own gunsight, the JSF jockey found he couldn’t maneuver out of the way, owing to a “lack of nose rate.”
The F-35 pilot came right out and said it — if you’re flying a JSF, there’s no point in trying to get into a sustained, close turning battle with another fighter. “There were not compelling reasons to fight in this region.” God help you if the enemy surprises you and you have no choice but to turn.

And to add insult to injury, the JSF flier discovered he couldn’t even comfortably move his head inside the radar-evading jet’s cramped cockpit. “The helmet was too large for the space inside the canopy to adequately see behind the aircraft.” That allowed the F-16 to sneak up on him.
