Kitbag,
All marks of AIM9 were aided by radar. Most basically to allow the shooter to perform an intercept and roll out in range. From the early 80s onwards, to slave the mx seeker head to the target.
Regardless of that, boresite, tone, uncage, shoot works pretty well for that theatre.
But Flap62 is absolutely correct. The GR3 would have been, effectively, a point defence Hawk. It was not what it was designed to do.
