Are you sure about this?
It is my understanding that within NEZ the missile can be defeated only by breaking some other link in the intercept chain, like tracking for example.
I would assume that missile would out maneuver the target as it can pull some 4-5 times more G.
Maybe SAMs don't have NEZ? Not sure.

Just checked out a BUK missile and it looks like it can pull around 20G.
So I guess it would be possible to outmaneuver.
