R27ER downgraded?

[IonicRipper]

Haven't flown in the Su-27 for a few months and I just came back to it to finally play this Ultimate Argument campaign I bought but never completed.

 

Unfortunately it seems the R-27ER can't hit anything anymore... Was the ER "nerfed" or something since 1.2? They keep missing my target even though the conditions are almost perfect for it.

I think I read they kinda downgraded them to flying bricks at some point. It's pretty hard to hit with them, much better option is go more stealthy and use IR missiles.

It's not the missiles, it's the chaff put out by the bandits. If you remove the chaff from the bandits, every r-27ER will hit

There's 2 issues affecting the R-27(E)R at the moment:

 

1. An unnaturally high drag coefficient which means it doesn't have the range it should have. This is however an issue that effects all missiles equally, both Western missiles and the Russian ones.

 

2. All SARH missiles suffer from very poor countermeasure rejection. The possibility of chaff decoying a SARH missile is simply probability based, so enough chaff is guaranteed to eventually decoy the missile.

 

There was a short time just after 1.5 was introduced where chaff wasn't working. For that few days the R-27ER, launched within parameters, had a ~0.9 Pk per missile. As soon as chaff was turned on again they became nearly dead weight.

Ive been going on about the abysmal performance of ERs for >3 years now:)

Thanks for the info guys.

 

So from what I understand, getting in closer before firing should increase the hit chance percentage?

 

Its a joy to come back to the Flanker, though. What an incredible plane to fly. The F-15 bores me to to tears compared hehe!

I ask the same question, but about the 120Cs, can someone tell me if they nerfed the F-15C, radar, 120? I've noticed a lot of changes between 1.5 and 1.2. Even the ECM, its behavior is a bit different

Yes and no. Yes, getting closer gives the target less time to react, which in our case is helped by the fact that the R-27ER has both a very high top speed and also very high acceleration. Unfortunately launching will always give your target a launch warning on their RWR gear. This coupled with the incredibly high susceptibility of the R-27R / ER to chaff means that even with little warning all the target has to do is dump a few bundles of chaff and the missile will be decoyed.

 

As an aside, this is why the R-27ET is very popular: it apparently shares the same seeker head as the R-73 which gives it good detection characteristics & good countermeasure rejection, and has the benefit of the very high top speed & acceleration of the R-27E weapons. This combined with the stealthy attack abilities of the electro-optical system offers an advantage that all the western fighters currently in DCS simply don't have.

 

Its a joy to come back to the Flanker, though. What an incredible plane to fly. The F-15 bores me to to tears compared hehe!

 

Definitely! It takes a lot longer to get used to it than the care-free handling of the Mirage or F-15C but when you do master it the Flanker is a real pleasure to fly and has some really unique capabilities.

I honestly don't have the same degree of problems with this missile that I hear so many of you have.

 

Though I wait till Rmax2 for all my shots.

[IonicRipper]

I also wait for Rmax2 but the missles still miss more then half the time.

HUD Rmax indications are of course dynamic, according to altitudes, speeds etc. The missiles though, in the majority of launches significantly above sea level cannot match what's expected of them from the indexers.

 

Rmax at higher altitudes doesn't take into account the dramatic degradation of the missiles flight post rocket burn. If you're foxing near sea level a lot, you'd notice this less as Rmax2 is alot closer to the missiles rocket burn time, so you don't deal with post burn as much. You're also a lot closer anyway giving the target less reaction time.
