R-73M also has better IRCCM than R-73, and more thrust which means it can reach longer ranges or faster targets
Any source for that?
I am not sure about the longer motor burn time I’ll have to check again, but it most definitely had better İRCCM. Because the seeker was completely changed. İt wasn’t just a simple gimbal limit increase.

Yes I think that’s right.
As I understand it, it should be:
R-73 should be ±45 degrees seeker gimbal
R-73M should be ± 60 degrees seeker gimbal + some kind of Russian SEAM that lets it engage at ±75 degrees
R-74 is a new name for R-73M aka RVV-MD?
R-74M should be ±90 degrees and gets a dual-band IR seeker, and has GLONASS + Datalink
I can’t speak to the IRCCM of any of them though
Whatever the next R-73 version will be called by gaijin, it’s supposed to have ±60 gimbal before launch, dual band seeker and better thrust providing 40 km launch range

I’m not sure the R-73M received the dual-band seeker. Everything I can find points to “A variant of the R-73M” and/or R-74M
This basically is what I’m saying, better İRCCM. This was introduced with RDM-2 in late 80s
İİRC R-73M is basically that, but never went into serial production because USSR collapsed. When it went into production later it got more improvements and it’s name was changed I think. So R-74. But I’m not an expert so don’t quote me on that
I can find info on R-73/RVV-MD/R-74. They’re all the same missile as far as I can tell, and all corroborate a ±60 degrees gimbal limit seeker, with ±15 degrees more angle using a kind of SEAM, but everything specifies R-74M for the dual-band seeker.
And that dual-band seeker also is supposed to have a gimbal of ±90 degrees

R-73M had the 60* gimbal limit, we know this. I will try to find it but I’m pretty sure it also had better İRCCM (of course along with longer lock range)
Afaik but I personally not sure myself about everything, cos there is none official info about that, the next improved R-73 that actually went mass production is R-74M and R-74 is R-73 with russian made seekers (because in USSR seekers production was in Ukraine)
İmo now that Su-27 and SMT cannot face 11.3 they should add R-73M with more gimbal limit and a bit better İRCCM at least, the İRCCM on this is a joke, along with MAGİC-2.
You can see in my videos how much of a joke this missile is Vs Gripen and F-16
You can have dual band seeker with less gimbal limit > R-73M. But I doubt gaijin will implement dual band seeker anytime soon. Magic-2 is proved in bug reports to have this, but it has copy paste useless İRCCM of R-73
This would also explain why there’s a ~15 year gap between R-74 and R-74M. They would’ve needed to rebuild production equipment and re-learn how to make an IR seeker after Ukraine left
Possibly, but again I can’t find anything that points to that missile having a dual-band seeker, or even really having an improved seeker at all. It might have gotten a better motor though, as it gains 5kg of weight and 5km of range in front-aspect.
Looks like I’d expect, Gaijin incorrectly models thermal signatures across the board (severely underestimates), and/or Gaijin severely underestimates IR lock range, making all missiles much more sensitive to flares than they should be.
Then, you’ve got the bad PID they haven’t been able to tune because of thrust vectoring + maneuvering fins (see SRAAM)
And then, you’ve got a lack of modeling electronic filtering, it’s not quite IRCCM but it should help. R-73 IRCCM is effectively irrelevant above a 1km distance, especially when your target doesn’t appear to be after burning.

in the front and rear hemispheres, against the background of the ground and with active radio-electronic counteraction. The upgraded R-73 RMD-2 missile could also boast resistance to external influences. The dual-band TGSN missile, which has been in service with the Russian Air Force since 1999, has had outstanding performance.
“In particular, the largest target designation angle is 120 on the pylon and 180 after launch,” military expert Alexey Leonkov noted in an interview with Zvezda. If we compare the R-73M RMD2 with foreign models (namely, any domestic weapons are usually compared with them), then the aircraft missile also differed in its target acquisition range - 18.5 kilometers in free space and almost 7.5 kilometers against the surface.
R-73M RMD-2 (RDM-2?)
Almost 8Km front aspect lock range, 19Km rear aspect
60* gimbal limit
Dual band seeker
Apparently there are 2 versions of R-73M, RMD-2 is first one.
What I wrote is about RMD-2, so the next model after what we have in game.
Later version is RMD-3
5KG heavier, so a little bit more rocket fuel, a little more range, reinforcing what I have read about a bit more range. R-73 has 34 KG fuel in the game right now. It will be 39 KG.
