The heads up display isn’t something you see in front of you like most planes. The helmets are the heads up display, like augmented reality.

There are cameras all over the plane to help you see through the aircraft (see ground target through the floor, enemy aircraft through your wing).

Just like how an apache gunner can simply look at a target to aim the gun at them you can do the same thing. And if you can’t hit it it’s still marked for every allied plane in the airspace to see. If you are out of missiles but you are tracking see a enemy plane miles ahead, you can send the data to an F-15 miles behind you and let their missiles lock and fire from farther than they can engage alone.

With that in mind the radar is awesome letting it see threats from greater distances than the opposition, with the stealth capabilities are good enough to keep them from easily doing the same.

I’m sure there are other surprises too, but the military obviously wants to keep those a secret
