While they can, drones are still limited by physics.

Sure, the aircraft can pull a ton of G's to defeat a missile or achieve a firing solution. Maybe it even succeeded at that.

It still pulled 9+ Gs and has burned an incredible amount of kinetic energy doing do. And the harder it pulls, the quicker it bleeds speed. It might not be able to defeat the next missile or outmaneuver the other plane's buddies because it is now slow and very likely outside its optimal turning speed.

Even today, missiles can pull dozens of G's yet still are defeatable by humans who can only pull about 9.

But they also have their limits.

Bolts and trusses (and solder joints) have tensile strength limits, but it can be higher than what humans can take.
