İt is bottom of the barrell. You will not win against F-15C who just keeps distance. You have to keep lock, and this isn’t the radar of Mig-29SMT with 90* lock capability
He has: better radar, better acceleration, better energy retention, more countermeasures for chaff spamming, better ARH AİM-120.
You have: R-27ER? lol
AAM-4 & PL-12 better than amraam in maneuvr, but some(little difference) worser than amraam by kinetics
AAM-4 got a massive buff in thrust so in relevant ranges the AAM-4 is superior to the AMRAAM.
Yes, but depends on alt
In wt ranges amraam will be better.
But aam4 better at high alts
Could you link the changes?
I think you’re overly underestimating the R-27ER. I’ve hit 70km shots with that missile using the stealth tactic.
İ can hit at 100 Km Vs clueless people who grinded with F-4S bombing that are flying straight in F-16C, it doesn’t mean you will beat an actual player.
İn all the matches I played F-15C, I always climb 7-8K kilometres, and never died to R-27ER at long range. Only Su-27 that I didn’t see and fired from <10KM R-27ER
Video of comparing will be better
Good stuff
Here’s a guy diving and cranking. Probably not notching to hold DL on AMRAAMs which is what I capitalize on.
Rookie mistake.
Again, the enemy doesn’t know what he is doing
You can always fire another missile, you don’t live again
Most people provide DL on their AMRAAMs long range or else they won’t go pitbull. The AMRAAM will have to rely on IOG to find the target.
You have more than 1 missile, and the missile money isn’t from your own wallet
You don’t need to go all in with your Aim-120
I’m not saying the ER is equivalent to the AMRAAM, but the ER is great at capitalizing on SPAMRAAMers climbing at high altitude. If you shoot at extreme ranges and manage your closure rate, there’s a really good chance you’ll survive the engagement and maybe get a kill. Like this:
65km kill and defending against 2 AMRAAMs and a Phoenix
For those wondering, the drag value is dependent on other factors. A larger missile will generally have a lower CxK than a smaller one.
Ramblings about CxK, Caliber, so on.
AIM-54A for example;
Caliber: 0.38
CxK: 1.005
AIM-7 for example;
Caliber: 0.2
CxK: 2.3
Some missiles such as the AIM-54 or AIM-7 are outliers in regards to CxK because of a couple of reasons. The first is that the AIM-54 is much larger than other types. Nearly double the size of the AIM-7 in regards to caliber. The AIM-7 in spite of being the same or similar caliber to the R-77, has a higher CxK (more drag). This is to account for the overperformance in thrust (and still doesn’t quite do it). The AIM-7’s total impulse is iirc around 20% higher than it should be.
Now to compare the FOX-3 MRAAM’s…
The PL-12 and the R-77 have similar caliber & CxK. The R-77 is expected to have a higher nominal drag coefficient than the PL-12 in comparison but it doesn’t. I think it is possible that the length of the missile is accounted for in the formula somehow as well as the caliber & CxK. I could probably run some tests to see if length affects drag.
PL-12;
Caliber: 0.203
CxK: 1.6
R-77;
Caliber: 0.2
CxK: 1.7
The R-77 is slightly smaller caliber, has slightly higher CxK. This shows that the R-77 has similar drag coefficients to a conventionally finned missile of similar size. The difference is closer than the 0.1 value difference of the CxK as well, since a larger missile will generally also reduce the CxK value in unison.
The MICA is an interesting point of discussion as well, being an outlier. The performance is an outlier because the drag value is unusually low for a smaller caliber missile.
MICA;
Caliber: 0.165
CxK: 1.65
Missiles of similar size and design (TVC) such as the R-73 have the following values;
R-73
Caliber: 0.17
CxK: 2.5
PL-8
Caliber: 0.16
CxK: 3.3
I think my conclusion for the MICA is that the TVC already causes a lot of wobble, combined with the fact that it should be lofting in most launches… they decided to reduce the CxK value so that it meets expected range criteria in spite of the shortcomings of the implementation.
Notably, the R-77 gained additional fin AoA (46 up from 40) while ever so slightly reducing lateral fin acceleration. Wing area mult value was increased as well. Excited to try this out. Unfortunately there is the return of the seemingly a-historical loft.
On the NATO side, the AIM-120’s fins AoA was drastically reduced from nearly ~37 to the historical ~27. I suspect this will put the R-77 ahead in maneuverability but it will still be close I think.
No, not really. Not against any opponent playing BVR with Fox-3s and respects incoming threats with appropriate evasive maneuvers. If you’re going to try to slap some inattentive fool with an R-27E, you’re better off reminding them that the R-27ET exists.
AMRAAM got a buff to its motor thrust too, so it should have a higher range despite a drag increase
Guidance delay was increased from 0.3 to 0.5 seconds for AIM-120A drastically reducing the time it begins to pull.
can’t see that in the datamine
