The R27ER has a thrust value of 55,000, and the Aim-120A has a thrust value of 22,300. Thats broken OP as hell for the R27ER. This explains why its accelerating at such a ridiculous speed.
It doesn’t matter, because the R-27ER doesn’t have an internal radar.
AIM-120A does, which means you can lose lock and it’ll guide itself in.
Russia doesn’t use R-27ER for a reason, even their R-77s are superior in capabilities; it was only ever developed for legacy aircraft that aren’t R-77 capable.

So you think a missile is OP because it has a high thrust value? Wait til you see the R-23…

Yes, because it doesn’t even come close to reality. Its 25% heavier than an Aim-120A, and its 15% fatter. It has way more drag. The engine produces around 5100 - 5900ftlbs of thrust. The ER just means it has a second stage. The Aim-120A & B produce around 7000ftlbs of thrust. Its smaller, lighter, and has a better engine IRL. It shouldn’t be slower.
I also find it interesting that its guidance system is set to 25,000 when the Aim-120 is set to 16,000 and that its max range is set to 100,000 when the Aim-120 is set to 80,000 in game.
It should be limited to Mach 4, not 5.7 and its thrust should reduced to 20,000.
Two Stages for R27ER
The Aim-120 is firing as a two stage:

2 diffrent types of missiles. Can’t compare. AIM-120 vs R-77 is more valid although dumb

Need a source for the R-27ER actual thrust values

R27ER is an extended range missile meant for BVR, how is it different? Its a two stage missile meant for BVR. The Aim-120 is a two stage missile for BVR. Except in game the R27ER is operating as a one stage missile with massive thrust, instead of two stages with different thrust.

Wrong. The in game R-27ER is a 2 stage with a booster and a sustainer.
1st stage is 55275N of thrust for 3.2 seconds
2nd stage is 26630N of thrust for 4.8 seconds
One has a radar in its head the other one does not. Diffrent tech

I see that further down in the code now. Its second stage is still wrong.
Ya you can’t really compare fox 1s to 3s
You guys
All seem to be
Missing the point.
Dude could have made the same point about the AIM-7M and it’d be pretty similar. The whole point is that the R-27 has unrealistic thrust and range.

I am comparing BVR vs BVR.

Gonna need a source
Which only makes your argument worse. I don’t care if the r27er is over preforming (which I am aware it is) unless it is going mach Jesus with 100g turn the 120 will still beat it in BVR. Now in wvr you have more of an argument. I agree with you that it is over preforming and needs to be fixed, but it’s better to do that by comparing it to a similar missile like the aim 7m.

It is going Mach Jesus. Its accelerating at 12,000+ftlbs for 3.2 seconds to Mach 5.75. It also has the range of the R27-ER1 at 100km instead of 70km it should have. So its a BVR missile for sure. Which is why I incorporated it with the Aim-120.
And yet the 120 will still win. Why? Because it’s an arh missiles. The plane firing it can fire and notch while the person with the r27 has to fire and hold a lock forcing them to choose between guiding the r27 in but dieing to the 120 or begin notching but lose the lock. That’s why you can’t compare fox 1s to fox 3s. Because they are two different types of missiles. you can’t just compare their stats because they are used differently. That’s why we don’t compare fox 2s to fox 1s or 3s.

If the scenario is BVR vs BVR…the R-27ER will impact around 3 seconds before the Aim-120 will if launched from the same altitude and same distance.
As a tool for BVR…the Aim-120 is far superior to the R-27ER because it has an active seeker and will pitbull at 20km.

While the r-27er has better engine and performance in general, they both reach the same speed and have a similar time to target
The aim120 also lofts, improving the performance at range
Although the max speed is stated to mach 5.8 in the statcard, the missile doesn’t actually reach it.
Let’s not forget the Aim120 is ARH, and is more maneuverable.
Also you said it behaves as a boost only engine, but it in fact does have a 2 stage engine (and it’s not that different from aim120)

get 2 good players together, Su-27 with 6 R-27ERs and an F-15 with 6 AIM-120As, the F-15 will win every time in BVR, The R-27ER may be suprior Kinematically, but the fact that you need to be nose hot for it to track and maybe hit, where the F-15 can start going cold once his missile has gone active, just makes the R-27ER redundant, as the Su-27 in this case would be forced to turn cold and lose lock, or die, while this happens the F-15 coudl re-engage and fire another 120, and rinse and repeat, if we had the R-27EA it would be superior (IIRC an R-27E series with the R-77 seekerhead) as it would have more KE potential while being self guided,
even then the AIM-120 would be better, the ability to terrain mask without losing your radar missile is much better, only thing the ER has is its acceleration there and hoping it connects before the 120 is fired
And this isnt really including how hit and miss russian radars can be, getting a lock to fire the ER would also be harder than the TWS lock for the AIM-120 user
