Not to be that guy but the 260 is unproven, it is a completly new missile design and the US first true purpose built BVRAAM since the AIM-54 (RIM 174 is an SM-6) The fact it is due for entry into service this year and there are no images of it, no test shots and no actual data. Leads me to believe they are not as close to entering service as the USAF and USN would like hence the need to rush the RIM-174 into service for the USN as they do not have a competitor to the PL-15.
R-37M however is in service it is being deployed and we have actual combat data on this system. It currently has the longest recorded A2A missile kill.
there are no images bc it is still classified and carried out on secure AFB. there have been many test shots already, dozens iirc. there is no actual data becuase it is classified
Those are not leaked documents, just propaganda numbers from LM for the F22, and unreliable simulations done on Ansys HFSS (a software primarily made for antennas and small electronics) using crude 3d models and a bunch of either wrong (metal skin, metal canopy) or unknown parameters for the SU57/J20/F35/Rafale RCS considerations. Oh yeah, and a very suspicious patent containg an average RCS (why would secret RCS information be on a patent? Yeah, makes no sense).
The S-500 is produced in two versions for air defense and missile defense…
Also, individual systems of the S-500 complex are integrated into the S-400 as ready-made solutions to improve the characteristics of the S-400…
For fun, here’s a simulation for the F22 using perhaps the most common of the RCS simulation software, one which has been seen in topic before.
As someone who has had a tad of experience with 3D modelling, I can affirm the F22 model chosen for the simulation is of way higher fidelity (overall shape, but even then it has innacuracies, such as the stuff inside the splitter plates) to the real thing than the models I saw on those other analysis.
Anyhow, as usual we see a bunch of simplifications to try isolating shape alone, aircraft is entirely metallic to check for geometry alone, no RAM/RAS interference. Welp, do we see the claimed -9000 gorillion DB all around the aircraft? As one would expect, that did not happen.
So, the settings on the simulation were:
8GHz
Aircraft is made entirely of gold
Frontal arc of ± 60 deg horizontal, ± 30 deg vertical, in 10 deg steps.
Excitation: Incident planar wave
Boundaries: Perf E
TLDR: minimum frontal was -17.53 db (0.017 sqm), max +10.33 db (10.78 sqm).
I didnt see this so late reaply. And no the claim and Radar track are online you can see both.
Further more there is an efficacy report on the VVS and how dangerous the R-37M is to UA aviation produced by the British MoD research and evaluation division.
