Ok, a bit better than R-3R. Still, I don’t think it will be a useful missile, even at low br
Remember that it’s not just the maneuvering limit that decides a missile’s maneuverability, other things like thrust, how long the boost lasts, the control surfaces and the overall aerodynamic design. I think it’s going to be good like the AIM-9G but avoidable if outmaneuvered using the rudder in high G maneuvers.
If it has CW seeker (i constantly forget what type of seeker it has). With pulse seeker it will be easy one-chaff and maneuverability would barely matter. We’ll have to wait and see i guess.
Since the minimun range is quite long they will probably implemented with a long guidance delay and with progressive gain, if i have to guess it will be similar to the aim 7D or the r530
Markovsky’s book on Soviet AAMs clarifies that the Su-15TM came with an improved radar with LD/SD MTI capability, and that the R-98MR came with improved ECM. I haven’t looked at other sources though, but if we take those 2 into account I think it’s going to be good depending on what BR it gets.
Along those lines yeah, I would take the R-23R’s guidance delay as the reference point instead though.
