It looks to be an R-27EP, this one was previously shown at other exhibitions. Whatever seeker is inside could just be a placeholder but the colored radome is only seen on R-27P variants.
Obviously the actual seeker being shown appears to be a 9B-1103 variant of unspecified size. The 9B-1032 seen in the R-27P guidance unit looks more like the one on the right;
Perhaps the plug was tested on the R-27AE in the 80s, but the project was closed in favor of the R-77
Why was the r-77 chosen over the r27ea?
From everything I can find, the r27ea would be vastly better in any situation that is not dogfighting range.
Better time to target, better energy, faster, etc etc.
probably a lot of R-27 parts were Ukrainian-made
or just cheaper
R-77 2x lighter. Probably higher reliability
The missile seemed quite a bit cheaper to mass produce and the parts designed to be easier to maintain / keep in storage. Shelf life would be higher, probability of kill much improved with the accuracy provided by grid fins. Maneuverability considerably enhanced against an enemy that was expected to be far more aware and maneuverable than the previous generation. Of course, it is lighter and one could carry more of them in theory.
If only russia could cook up double pylons for R-77 for something that isn’t a Flanker’s belly…
That is very unlikely
According to Ruslet it was due to budget reduction in 88/89 year:

Does anybody know what this book is and where I can get it?
That book?
Maybe, or maybe this one. Do you have PDF for any of them?
I was looking for R-24T and R-27T seeker info.
No
You won’t find info for IR seekers in book about radio equipment manufacturer book for sure
Oh, didn’t know they only did radar seekers. I just don’t know who manufactured the IR seekers for 24T and 27T, so I was just looking for any book I could find.
NPO Geofizika IIRC
It is a developer of Homing Heads, but not a manufacturer…
I wrote in detail on the old forum, but that was before 2022, I won’t do it now…
The R-23/24 manuals are on the Internet and contain information for the thermal seeker.
Do they contain info on how its IRCCM functions?
The R-23 and R-24 do not have proper “IRCCM” but are more resistant to flares. Likely just a reduction in FoV.
The R-27T documentation from the Moscow Aviation Institute is much more in depth but does not seem to have much on the actual function of the IRCCM. It covers mostly the guidance, motor, radar seeker, etc. The IR features seem to be more secretive. It is implied the IRCCM of R-27T is much better than what we see and the same goes for the R-73 data.
Dev response is that the game engine cannot handle gateWidth smaller than 0.5 for air to air missile IRCCM currently, there exists stuff with smaller FoV in-game but these are balanced in other means. They essentially stated all IRCCM missiles are nerfed intentionally.
