the Su-27M
which one? su-37 (su-27m bort 711) had only 2d, and su-27m 710 only had 2d as well but tilted (AL-41F-1F)
oh you asked for 3d tvc
then no
unless you consider 2d tvc + splitting the throttles as 3d tvc

Anyone have any decently sourced numbers for the Irbis-E’s search volumes and scan speed?
1 Like
best source for finding out the scan speed is probably this video:
it appears to be 20° x 8 bars
white line shows search sector
white dots move everythime a bar in the pattern is completed (has 8 different positions in the video so i assume the current scan pattern uses 8 bars)

Ok, I wasnt sure exactly what the scan pattern used in the vid was.
As a sidenote, some people have pointed out that that vid shows the Irbis-E to be considerably worse than its usually stated, with it only being able to track a fighter sized target on a narrow scan pattern, and only omce it hit around 100km.
If thats the case, it seems like its able to detect a target from much further out than its actually capable of getting any kind of weapon grade lock. Not a big deal for WT with how small maps are, but a major difference between 100km lock and the ~350-400km often claimed, and puts it pretty much in the ballpark of radars already in-game.
Id likw to dig into that vid some more when I have the time.
Its detection at 350-400km and then engagement at around 160km for 3m^2 target if I remember right, I have to double check
speculation is that the video is a test against targets with lower RCS than a normal fighter
it is certianly able to track targets at +160km
it possibly is tracking fighters as it seems it is a two-ship
(so a fighter lead and wingman)

Okay low key it says nothing about the radar actually engaging at those ranges, just detection. I got the 150km from apparently target detection tail on for 3 m^2, not actually tracking. The biggest thing I can find is that it says irbis allows customers to engage with 300km + missiles, but not actually engage at 300km

Spoiler
In long-range detection mode, within a 100 sq. degree zone (±60° of aircraft centerline), Irbis-E shall detect 3 m² RCS air targets and measure their range:
• Head-on: ≥ 350–400 km (with target altitude > 5,000 m, sky background: ≥ 400 km);
• Tail-chase: ≥ 150 km (with target altitude ≥ 10,000 m, sky background).
Detection of “very low observable” targets (0.01 m² RCS) shall be up to 90 km (roughly equal to the max fighter-class detection range of 4th-gen radars on Su-27 and F-15C). Group-target resolution at 50 km: 50–100 m in range, 5 m/s in velocity, 2.5° in angle.
With the customer-specified weapons set in A/A mode, Irbis-E should enable simultaneous engagement of up to 4 air targets with long-range (300+ km) missiles, or up to 8 targets with medium-range RVV-AE.

@MythicPi this is about all the info for irbis you will find on the internet
We sure thats the track symbology and not something like a datalink track?
