I have read some articles about some new Russian air-air missiles entering service but nothing has being specify. So while Eu is introducing Meteor and USA Aim-120D what is going on with R-77 modification. There has being some talk about R-77 with extended range and one with ramjet engine. Does someone have more information about this missile?

What is the current range of the R-77 ?
aprox. 90km

This is basicly for had on fight and for the missile fired at hight (althrow not sure what). So this is basicly maximum posible distance at whitch missile can travel in optimum circumstances althrow estimates goes from 90-100km.

is this purely a counter ISR asstet weapon?
much less than that, about 50 km vs fighters. And in terms of NEZ, probably less than 30 km?
What i am more interested in is evolutionary subvariants of R-77. Mainly modernization of radar, computer, fuse, datalinks, etc. Just like AMRAAM went through 6 iterations from its birth... just what changes were implemented in r-77 since its first version 15 or more years ago? There seems to be little to no info on that on the internet. 
Actually R-77 have many versions. Depends on how you define. For me, they are all different missiles with a same codename. The latest model, the ramjet R-77M RVV-AE-PD with a Heat-seeking or anti radiation seeker, may have a maximum pole range of approximately 150km/85NMI. In contrast of the origin model, 80km.
not really, that ramjet version is still in development.Actually R-77 have many versions. Depends on how you define. For me, they are all different missiles with a same codename.

I'm not sure about the improvement on R-77. I have read about improved seeker, but have not seen evidence that it's actually in service anywhere.
Also depends on target aspect and altitude. For example if the missile is fired from the rear in a tail chase. The range is even less. This applies to all AAMs. These missiles "cheat" by flying in an arc trajectory. Their rocket motors accelerate them to ~M2.5-M4.0+ depending on the missile and burn for about 10 to 15 seconds while the missile climbs. The missile uses the decent to take advantage of gravity to reduce drag induced deceleration. Control surfaces like canards and wings to make maneuvers during the endgame to defeat evading targets. The further away the target is the less energy the missile has for the terminal phase. So if the target aircraft is running and far enough away. A missile with a 50km range for a head shot may only work in a tail shot about ~10-20km with reduced effectiveness. Ramjets could change this.

I was thinking against a 4th generation fighter jet. Altitude would be at 10 km and facing toward each other flying at mach1.2. I think that's the aspect and altitude that the AMRAAM range are measured under? Correct me if I'm wrong.
I wouldn't go so far as to say you are "wrong". Just that you described a specific circumstance. My intent was only to add a little more detail about how the tactical situation can often change things dramatically. At 10000m head on I don't see 50km as unreasonable for R-77 or AMRAAM.

At that height, the AAM should be able to go further... i have read that the R-77 has longer range than the AMRAAM, is it true? If so how much more, anyone?
Well, the range part is quite confusing. From my observation, Russian and American uses different base or standard to measure the range. From my knowledge, present in service, despite of up coming new models, AMRAAM have a slightly longer range.
Just for your knowledge, other than R-77, R-27AE too have an impressive range of 120km. R-77 seems to be looking for range above 150km, however ramjet still in development process.

With the ramjet AA missiles coming slowly in the use (Meteor, R-77M1, I dont know what will US do (go with the Meteor, stick with the AIM-120D(bad idea) or develop its own ram jet missile (they at least have money) it will radicaly change AA combat because ramjet missiles will during all its path have enought energie to fly any atitude and chase planes not 10-15 sec of rocket boost and that gravity will do the rest.
As now situation stands range of the missile depends on enemy fighters atitude, your fighter atitude and of course is it being chased or head on.

A quick question : who operates the latest variants of AIM120 (the C and the D) ? Data on the net is very confusing about this. For example I've read that our (Italian) Typhoons operate AIM120C and on another magazine I've read that we're sticking to AIM120B while waiting for Meteor...

According to Andrew McLaughlin, HORNETS DOWN UNDER, Phantom Media, Canberra, 2005, The RAAF acquired a batch of AIM-120C-5s in 2004. I can't find any info though as to whether it has now moved on to the D.A quick question : who operates the latest variants of AIM120 (the C and the D) ? Data on the net is very confusing about this.

last i heard was 86.5NMI was the range for R77 but the record to date is the R37 in 1994 trail test it has affectively killed a target at 162NMI . it can hit a target at 215NMI it does so by gliding mid course and switching the burner again has of now it has only been used buy the russians in there MIG31M.

Wait a second I tought R-37 was cancelled project in favor of Indo-Russian codevelopment of KS-172.
Is this a confirmed news???I had also heard a rumour bout this a few dayz back.
