Sukhoi Su-27/30/33/35/37 Flanker series & Su-34 Fullback - History, Design, Performance & Dissection (Part 2)

So I did some digging into Russian missiles and how the developers came to model the R-77 and the R-77-1 as well. I figured some things out but also was left with a few questions.

There is the R-27ER which is modeled as having 65km frontal aspect range in the given conditions of 10km altitude and 1,100km/h TAS co-alt and co-speed.

Notice the given conditions though, 10km altitude and 1,100km/h TAS for both the shooter and target.

I plugged in the currently modeled R-77 and R-77-1 in those given conditions. The maximum range for the R-77 ended up being 80km and the maximum ranges for the R-77-1 ended up being 113km (still within the 5% range margin of 110km). This aligns with the given figures from Rosoboronexport that states 80km and 110km respectively for each missile.

Knowing that this is how they model their missiles, the R-77 and R-77-1, is there any reason to expect that they won’t model the R-37M any differently with the same method?

Rosoboronexport lists the R-37M as having up to 200km.
RVV-DB

rvv-bd appears to be a modified version of r-37, not r-37m.
here is rvv-bd


r-37m has two datalink antennas, not one.

also, considering modified r-33 with a lofting algorithm was able to reach 228km range, i doubt rvv-bd;s max range is only 200km (which looks like export modified r-37 and not r-37m)

Did you take a look at the Mig-31’s launch speed in that scenario? That’s Mach 2.2 launch speed (2,400km/h) compared to 1,100km/h TAS at 10,000m.

R-37M at Mach 2 for both launcher and target would far surpass 200km into the 300km area of course.

fair, but i still doubt they will model r-37m off rvv-bd just cause theyre different missiles (though both were based off r-37)

i mean the target is also going around 700 kph

Tbf, I did just showcase that they modeled the R-77 and R-77-1 based off of export range figures. In fact, Gaijin was already caught referring to Russian missiles by their export names in the form of RVV-MD.

the RVV-BD is not a R-37M

as pointed out by kizvy

its possible that it is ‘only’ 200km due to international laws on exports on long range missiles as some ppl have said

Is rvv-bd similar to r-37m like rvv-ae is to r-77?

I’m pretty sure this is about cruise missile and only for those having a big enough warhead.

The question then is, what is stopping them from still using RVV-BD figures even if the model is externally different?

RVV-BD has a 60kg warhead

which i would consider as a big warhead

becasue it is clearly not the same missile

why would the r-37m have less range than they achived with the base r-37

maybe the goal was the get more speed and g load ?

why would you want a higher g-load on a missile thats designed to shoot down AWACS

to be able track agains faster when lose lock ?

I don’t think it is for the goal of the international law, and well, it’s about preventing a customer from replacing the conventionnal warhead with a nuclear one which would be a problem so 60kg isn’t much.

thats not what g-load does at all

luckily we are out of the phase of the cold war where everything had to carry a nuclear warhead

like torpedos, seamines and so on

well its one of the important factors when you make a new missile
