Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection

Source?

Unless google translate is butchering it or I’m reading it incorrectly, the -14 elevation limit seems dog**** (and contradicted by the +45 deg listed in the export catalogue) and is that “3 to 10 degrees electronic steering in azimuth”?

-14 is not for azimuth.

For azimuth ±70 mech scan + 3-10 electronics scan.

For elevation it is from -14 to + 40 electrical stan.

What was the ‘T’ number for the Su-27SM that we currently have in game, as well as what Flanker it is?

For example, the base Su-27 is known as T-10S and as the Flanker-A (This is for the WTHLM Lang Mod)

If possible, a link to the source if you have it.

Yeah I meant -14 for elevation.
Seems really bad … Like I can’t understand how it can be this bad-level, bad …

BTW any ideas as for the discrepancy?
Rosoboronexport catalogue lists ±45 for elevation (purely electronic beam steering).

  1. Opsec and one or both documents is a lie.
  2. Both are true, but talk about different versions of radar.

NIIP’s website also lists ±45 deg electronic steering (for the export version at least)

Don’t worry, that’s not quite true…

The first link makes me think that the -14 to +40 elevation and ± 3 to 10 deg in azimuth figures could be for some sort of ACM mode:

It’s flanker b not flanker a. Flanker a was prototype

Which standard Su-27 do we have? as there was many Flanker-As and 2 Flanker-Bs?

We have an flanker b (j11/su27sk and su27s) and a flanker e (27sm) although the 27sm that we have in the game never existed, it’s weird

So the Flanker-E Su-27SM doesn’t have an idz. T number? Even tho some sources say the SM was a mid life update for the Su-27

I sent it to you in Russian…Are you not from Russia? …
.the scanning area during the preliminary search and capture of a target in close combat, degrees:

  • by the angle of the place -15…+40; +7.5
  • azimuth +3; +10…

And a photo of Irbis/Bars…
Look at the gimbal…A Bars has a larger antenna diameter, and it will not be physically able to turn 70 degrees…
So _40+30 degrees…

It technically never existed cause this is sort of a put together aircraft just so it can come earlier without its weapon of choice or some of its real equipment.

-14 to -15 is quoted but isn’t true, that is just for the close air combat vertical scan mode.

These radars have +/- 60 degrees vertical scan and up to +/- 120 degrees coverage thanks to electronic steering + mechanical gimbal limit. This is directly from Sukhoi, it is a primary source.

That’s for Su-35 though
N011M by most accounts (including official export brochure and the specs page on NIIP’s website has ±45 deg in elevation and ±70 deg in azimuth (45 deg electronically + 25 deg mechanically).

It is an example, the Su-35 is not the only aircraft that radar can equip. They gave Rafale AESA there is no reason to continue limiting the Sukhoi’s with lower end radars.

We will have to see, but there’s a good chance that Gaijin won’t directly jump to Su-35 or Su-30SM2 right away (Even though there’s no reason not to IMO), and will instead go with Su-30SM.

AFAIK Su-35 and Su-30SM2 are the only aircrafts in Russian service that use the Irbis-E radar, and Su-30SM only uses the N011M Bars radar.

Still, my point is that when you see -15 degrees listed these radars are not talking about a maximum negative scan limit. They’re talking about the maneuvering air combat vertical scan mode.

Yeah, I understand.
What I mean is that even with the 45 deg electronic steering + 25 deg mechanical steering only in azimuth, it’s not gonna be that great, compared to e.g. RBE2, which currently gets 70 deg electronic steering in both azimuth and elevation (not sure if realistic), or e.g. APG-83 which will come eventually and gets 60 deg electronic steering in both azimuth and elevation.

(60 degrees seem to be quite typical for ESA radars, and seems to be what Irbis-E gets as well, in terms of purely electronic steering)
