"AWACS killer missile is nonsense because it can't work."
 
clarification.
 
reds assessment is not viable unless it takes into consideration what blue does to counter attacks on an AWACs.
 
long range shots in isolation of blue behaviour in a combat box is not a true test of weapons system capability

R-77 doesn't use a lofted trajectory?  Or is it a chaser?
Yes it does, and no it isn't. It just suffers from the same thing SPARROW did, lousy initial manufacturing and a finicky pro-nav solution.
 
Steerage for endgame could be better for weird grid fins, but that is because of its weird tail steer effect  at Mach 1.5+

"Despite these drawbacks, the improved maneuverability grid fins offer at high supersonic speeds and high angles of attack have resulted in several grid fin research efforts in recent years." - Referenced from article.

Now i know the context was within an endgame scenario, but the missile need not decelerate for terminal... 
Or is there something more?

After burnout, the R-77 tends like most missiles to lose speed due to drag. That means it will, as it drops below well Mach 1.3, be stuck with grid fins whose heart of the shock wave now does not form mostly aft of the grate, but in front of the grate. The drag on the grate dramatically increases, and the lift control induced by grate pivot goes to mud. When the missile finally has to jerk hard and use tail steer to correct lead at final merge after a long flyout and the loss of so much speed? It can't.
