R-27 variants

10-20GHz is J-band. So for example the R-27P wouldn’t be able to target the Tornado F.3 as it has an I-Band radar. The targets will have to be in the 10-20GHz range.

The ALARM anti radiation missile has a range of 2-18GHz which covers most radars in the game.

The R-27P is going to be pretty useless in its A2A role and in A2G it’s going to be pretty limited as well. As most search radars are very low band so it will be limited to tracking radars and if you’re being tracked that’s not a great situation to be in.

It’s R-27R’s SARH seeker, not R-27P’s. As well “item 470-1” is R-27R. Somebody confused russian “P” (R) and english P.

I thought most aircraft radars were IEEE X band, which is 8 - 12 GHz (i.e. straddling the border between NATO I & J bands). So it might be useful if the radar is on the upper end of X band.

I was under the impression that R-27P was meant for the air-to-air role, so would expect it to have some capability against such radars.

I was under the impression it was meant for targeting things like AWACS but generally failed to hit anything.

This paragraph from David Gledhill’s book on the F.3 implies that it was a concern for Tornado pilots. But maybe Britain wasn’t sure of it’s capabilities so just assumed the worst case scenario (that it could be used against fighters).

Edit: He mentions it again here:

Given how over estimated some the of R-27 missiles are in the F.3 tactics manual I don’t doubt they were worried

16

yeah i realised too late, srry

I checked the productions company’s website and even there it seems ambiguous and the picture seems very old as if no new models are available for show:

The main tracking method seems to be a (emphasis on the SEEMS) automatic radio emission detecting seeker head which scans the ‘forward hemisphere’. i doubt it is capable of scanning the entirety of a hemisphere keeping in mind gimbal limits.

That doesn’t stop gaijin from making them absolutely impossible to dodge and equipped on everything from mig21 and up.

well tbf the current R-27 variants in game are pretty easy to notch as for dodging, they can be min ranged at 2km and as for max range well youre pretty much boned unless u got pheonixes

21

It does because Gaijin admitted as such for anti-radiation missiles. They’re not as useful as people think.

@Gunjob
might you know of this?

[Avtomatika 9B-1032 X-band anti-radiation seeker]

or maybe this?
[CNS 9B-1102]

Spoiler

R-27ep seeker

Because if this is an X-band passive radiation seeker like the sources say, we might get to see the R-27P/EP in game someday.

The missile has a reduced overload relative to other versions of the R-27, and will also easily lose the target if it turns away. In War thunder battles, its effectiveness will be low

24

as far as ive read, the targets acceptable overload is around 5.5G and the missile itself has the same overload limits as the other R-27s.
i doubt, the russians would make a modern missile that is incapable of hitting anything plus its designed to target small fighter aircraft and not awacs

25

I made a report to fix the MiG-29s AoA, no dedicated MiG-29 thread so posting it here I guess.

huh apparently it got acknowlegded!

27

Yes I meant that

28

i was confused for a second thinking when did i write in cyrillic lol.
but yeah, missile overloads are usually calculated by two values, relative target overload and missile overload.
the actual missile capability is somewhere between the sum of the two values

29

She has quite a specific guidance. And if the target turns away and the reception stability becomes weak, the rocket may lose its target
