The F-35 is designed to eliminate targets that it literally cannot see, in some cases because the curvature of the Earth is in the way.
When you’re at 5km, the horizon is hundreds of kilometers away. When your target is also at altitude, it becomes thousands of kilometers.
It’s more a problem that a top-down look at an F35 from 100km is the size of a period on a page, from 3m away. And possibly behind a cloud. And not moving laterally at all, just very slightly growing until you explode violently because it actually does have radar.
