I read it as well but I dont think that version with F-4J is correct.

It could be f4e late with PD then?
I mean that missile seekers RGS-25 (R-40RD) was developed from RGS-24 (R-24R) so MiG-25 must use radar which is technologically close to MiG-23 one. Thats why I think that F-4 version is not very probable.
Mig 25 uses inverse monopulse coded radar, so its definately a bit different. Other than that, pulse doppler is just basicly filter, all you need is that your radar needs to be able to identify the shift in frequency due to doppler effect

Don’t have all missiles from the R-40R inverse monopulse seeker? I read that RGS-24 was inverse monopulse as well.
Maybe they used filter technology from F-4J. I can’t confirm or deny this, but we should expect it to be similar in characteristics to the Sapphire-23 radar as it was based on that (but better). It would be ideal if we could find a manual for it, just like for the Sapphire-23.

Some manuals about different variants of MiG-25:

I understood the P and RB models, I’ll add these as sources to their respective suggestions, however what is the middle one? Called Type 02B?
For the record, I got PD and BM pending.

I am not sure about that but maybe this?

The RBV is recon and strike right?
What does that say? I have basic Russian knowledge but I can’t read this language
Thats Czech.
Compared to RB it got more advanced SIGINT device, new navigation complex, lighter tail area without 600 l fuel tanks and installation of ECM.

Thanks for the translation. I should learn some basic Czech tbh

1- Mig-25 has relative wing area but very thin wing, it does not have slat or LERX either so the lift coefficient isn’t high compare to other aircraft
2- Ultimate limit is not the same as the usual safety G limit, there were some case that even an F-4 survive 12 G pull, but it doesn’t mean it will survive every time
3 -Mig-25 sustain turn capability is not even remotely close to that of F-15 or F-16, unless we talking about some extreme altitude where the other two can’t even fly
