reported R-27R missing targets also as 27ER.

How much of this do we think is chaff? 
 

It seems ridiculous to me how it seems to respond to severely to pretty much any chaff at any aspect. It is not simply guiding for center mass between chaff and target but making wild snaking maneuvers that send it ridiculously off course. 
 

Against AIM-7M, chaff causes no such maneuvers, only a loss of lock if you happen to chaff close enough to the beam with enough chaff. 
 

The radar is written to be resistant to chaff, I can’t imagine the missile aren’t also being monopulse pulse Doppler. I will upload tracks soon 

I do see it miss target pretty often just barely without chaff, but these are clearly two different behaviors that result In misses 

If the R-27 R/ER was the Cookie Monster, most of the cookies would be eaten. Anytime I test without chaff available, the hit rate goes way up. That even applies to long-range shots toward the outer limits. Using Dipirona4100’s R-27 track, I went from something like 12 out of 20 hits with the first missile to 19 out of 20 after removing the target’s chaff in the ME. Admittedly, that’s not a lot of trials but…

SO SAD

I pay the money to get the MiG-29, but all I got was a useless R-27 missile.

No wonder I get beaten up by the blue team on popular PvP servers.

Please, ED, fix this as soon as possible so the red team can have a fighting chance against the blue team.
PLEASE PLEASE

[AeriaGloria]

The chaff weakness is ridiculous. Wild maneuvers from chaff even if not beaming. I know from reading manuals that N-019 is resistant to chaff, idk about R-27R/ER but I can’t imagine it’s monopulse seeker is this weak when deformed in tandem when N-019. 
 

With this weakness to chaff, it’s almost 99% chance of decoying this missile as long as you know how to release chaff. 
 

Im not an expert on radar, but I expect this maybe from R-3R or AIM-7E, but 1980s R-27R/ER? 
 

The real kicker is all AIM-7 variants are still using original chaff modeling. They will not maneuver or swing wildly to the side from chaff. If you release chaff in the notch enough they decoy yes, but before that point chaff has 0 effect. 
 

AIM-7M/MH/P should have about equal accuracy to R-27R/ER, whatever is believed the missiles are comparable and I’m not sure it is completely known if one was weaker to chaff then the other, and definitly not to your average consumer. 
 

This is a game and a sim, and it feels wildly un fun right now and I’m not sure about this simulation of chaff. You could bring AIM-7M/MH/P to same level but then what, we just have almost 100% chance to decoy a 1980s fox 1 in 0 degree aspect straight and level flight? 
 

I am so confused. It’s been a few patches and many weeks since MiG-29 FF came out. And its really reduced the value of the module to be so gimped compared to AIM-7. 
 

I get that some weapons might get realistic things modeled before others, but this is too much when AIM-7E/R-3R is more accurate, it’s been over a month and a half with no end in sight, and we have no idea when or even if this module will have the value or parity of a blufor sparrow thrower in a 1980s environment. I am sorry but this is getting more serious to me then your average bug track when it seems we have no end in sight to this lop sided game of R-27R/ER being chaffed with no effort and a AIM-7E hitting fine.

Completely agree. It gives no incentive to fly the FF MiG-29 in its intended and primary role because its primary BVR weapon is so gimped. To hell with your "new seeker model". Bring the old seeker model back. Or if ED intends to keep this model, please adjust the chaff resistance. It's as @AeriaGloria says, 99% miss when chaff is introduced.

 

[Ironhand]

Susceptibility to chaff has always been this missile’s weakness in the sim. Doesn’t seem any worse than previously, though. Much more often than not, in a BVR dual, it’ll be a missile with an IR seeker that will make the kill. The R-27R/ERs just give you something to do, while you wait to make the R-73 kill.

[AeriaGloria]

Disagree. It always had same chaff resistance as AIM-7M when we look at at LUA

Yes, I know. Some of the above was hyperbole, though I have had it happen.  Very disconcerting when it does.

True, it is susceptible, but not to the extent it does right now. Just one or two chaff is enough to spoof the missile, sometimes, even that is not required. The current implementation of the new seeker model seems way off.

This issue has been reported for over a month, but we still haven't received any hot fixes.SO SAD.
Maybe two more weeks Right?? ED

the only useful track replays in this thread were posted 20 hours ago and we will check them, currently we are not seeing any issue when we check, most of the time it is due to not having good locks or bad launch parameters from the user. As mentioned we will check the new tracks and let you know. 

thanks

I have here some feedback from the team, 

R-27chaff1.trk
At a range of several kilometres to the target F-15, an Ace level pilot performs a precise 3-9 notch with a vertical dive, as a result both missiles go to chaff.
In the new version with reduced RCS of chaff, the missiles do not go to the chaff and the first missile hits the target.

R-27chaff3.trk
At a range of several kilometres from the target F-16, an Ace level pilot performs a precise 3-9 notch with a vertical dive, as a result both missiles go to decoys.
In the new version with reduced RCS of chaff, the missiles do not go to the chaffs and both hit the target.

R-27chaff6.trk
At the moment the missile approaches the target F-14, an Ace level pilot performs a precise 3-9 notch, as a result both missiles go to chaffs.
In the new internal version of DCS with reduced RCS of chaffs, the missiles are also distracted by the chaffs, but after a second they return to the target, but it's too late.

It is worth noting that you are using Ace level pilots as opponents, who masterfully perform 3-9 notch. They are good at evading missiles.
If you put an enemy pilot of a lower skill, the result will be different.



Additionally, we've begun work on converting the AIM-7 seeker to the same components as the R-27. Soon, these missiles will be the same generation of our technology. This will be in a future update.

thank you 

[RaymonD]

Dear developers. Have you taken into account the fact that a missile with INS and radio correction is flying with its seeker turned off and shouldn't retarget to the dipoles? In the game, I've noticed that a missile flying to its maximum range can often immediately retarget to the dipoles while still outside the missile's seeker lock-on range.

It's strange to hear this from you, considering that missile versions prior to the AIM-7M had conical scanning, along with other technologies and poor jamming immunity. I think this is worth considering. I'd also like to point out that the R-27R missile family uses a monopulse guidance method, which was introduced in the AIM-7 missiles starting with the M model.
In the next patch, I expect to see the R-27R missiles' jamming immunity no less than that of the AIM-7M.

[Muchocracker]

That's not what he said. The aim-7 will be brought up to the new systems modelling introduced with the R-27. Not that all of the aim-7's will have monopulse antennas.

You really might want to reset your expectations to avoid disappointment.  The chances of this making the next patch are pretty much zero.  You're assuming they have a dev (or more) they can put onto this immediately, that it's a quick fix, that it can be integrated into the release build in the next couple of days and that it can be tested before that point.  Note that BigNewy said "A FUTURE PATCH", not the next patch.  In a best case scenario you're probably looking January before there's any chance of seeing it.  That's just development and testing reality.

The missile in the DCS does not re-target to the chaff during the inertial guidance stage.
