Launching missile with radar single target track, then switching to IRST “suspends” datalink - missile loses IOG updates, but aircraft doesn’t break datalink with the missile, as showcased by vertical line above radar/IRST contact. The moment you switch from IRST to radar lock, datalink is restored and updates missile IOG
with the glitch it did provide datalink while on irst lock
Yeah providing dl through irst is completely nonsense lol, glad they removed it
RVV-SD (R-77-1) should have a target acquisition range of 18 km according to its product sheet.
Presumably against a 5m^2 target.

are we sure this is R-77M seeker? its stats is worse than R-77-1 seeker dawg
also only 100mm diameter?, R-77-1 seeker is 200mm
really? how?
multiple versions, but idk, it’s not confirmed. It’s just what most sites list it as r-77m seekerhead as it’s the only aesa seekerhead that would realistically fit on r-77m, the other aesa seekerhead is most likely for izd 810

R-77-1 seeker, 20km against 5m2 target
R-77 seeker does 16km against 5m2 target
this seeker does (4th root(5m2/0.003m2))*2km = 12.78km against 5m2 target
that was one of the prototypes of the entire family, those seekers are meant to be upscaled and downscaled according to requirements

Problem with 9B-1103M is that it went trough bunch of modifications without change in designation. R-77M might have 9B-1103M but it is not necessarily this specific version of 9B-1103M that is shown. There is also a matter of 9B-1103M-150, 9B-1103M-200 and 9B-1103M-350 family and not concrete info of how exactly the family tree of those seekers look and if they are even used or not by domestic Russian missiles or only installed into export versions

Does anyone have some info on the Turn Performance of the R-77M? I’d assume it’s worse than the 77/77-1, but is it like the 120?
Damn, less maneuverable than r-27er (r-27 has same g load but can go up to 40 aoa)
not sure if that is missile AoA or fin AoA tho

a bit related to the r-77m topic, george on twitter shared this patent related to the dual pulse mechanism of the r-77m - RU2715453C1
Spoiler
i find this part interesting because it talks about a small 2.5% loss for the 2nd pulse because of the separator mechanism in the way, i think gaijin won’t care about this loss considering the derby ER has the same ISP on both pulses

90% sure that would be missile AOA

is this actually for r-77m? The text in the patent makes it seem like its for a SAM

Gaijin will see that and make ti pull max 25 gs.
Does anyone know stuff about R-77T?
Just heard about it in this video. I’m a bit… skeptical about its existence.

to my knowledge it was only a concept, if at all
