Default R-27ER update?

Since the Aim-120 and Aim-7 has been updated, any news on R-27ER updates?
Let's see that Extended Range come to life

According to what Chizh said in the Russian forum (and assuming I have not mis-interpreted), the R-27ER is correct as is. Its range is extended compared to the 27R.

What? So it has already been changed? I thought it would recieve new navigation/flight characteristics to fly more efficiently...

Range has always been extended compared to the 27R. 27ER should (according to Keith "Okie" Nance) outrange the Aim-120, don't know if that is still the case with the new Aim-120 updates...

I don't know who that is, and no, it shouldn't. While it can get up to higher peak speed in comparison with AMRAAM, it has neither the guidance tricks nor the low drag of the AMRAAM to be able to out-range it.

This. The advantages of the R-27ER have always been a higher top speed and better acceleration. Assuming equal launch conditions it's never going to out-range an AIM-120C5 or god forbid a 120-D7.

Ok, thanks for the info 3:40 into the video he mentions the Amraam vs 27ER.



"Okie" has 6000hrs in different fighters. 850 traps (300 night). A-4, F-14, F-5 agressor pilot, F-16 etc. Very knowledgeable about air-air combat and tactics. But it might be bad memory or
the Aim-120A he compare it against... Great Q/A, and another one recently came out.

The AIM-7 reaches some 25nm where the R-27ER reaches 35nm (with lofting, the AIM-7 should come up to 30nm). Under those same circumstances (30000', 0.9M head-on) the AIM-120A (and B) falls almost squarely in the middle there at about 30nm. AIM-120C with its bigger rocket motor should easily match the R-27ER. That's all without lofting, and R-27's don't loft.

Of course, that's just armchair analysis so take it with a grain of salt.

As far as ED is concerned, they have the missiles where they believe they should be.

I thought so and with all the changes recently I have a feeling ED is looking to improve their missiles.
