Disagree, as the SAM crew can always decide when to start illumination or not.
If there are Weasels at the opposite side, just keep off the air, till the next opportunity...

That is the million dollar question, that both parties are investigating in Ashuluk, and New Mexico.
My guess is that the real answer has not much value, as the F-117A was quickly removed from service after faced Col.Dani in real combat.

(of course, if anybody knows, what range the RPN could detect a MiG-21 [standard Soviet RCS target], than it could be easily calculated...)

You should see the coincidence, that caused the two F-117A hit during OAF.

Originally the SA-2 was designed with the P-12/18 Target acquisition Radars. (Immune to the HARM missiles)
While the P-18 had ~30km detection range against the Stealth, the RSN-75 had only ~10km in Wide Beam mode.
Pretty much at the minimum effective range.

Originally the SA-3 was designed with the P-15 Target acquisition Radars. (Susceptible to HARM's)
While the P-15 has ~15km detection range against the Stealth, the SNR-125M has bit more than ~15km.

The Serbians mixed the SNR-125 and the P-18, and it turned out to be an accidentally deadly mix...

If the primary goal to PVO is just to survive - yes, that's it! I believe that PVO must work in a groups of different SAM types - this at least will make jamming much difficult, due to different radar types/methods.

Actually, jamming against an S-300P RPN, or Patriot TWM is totally ineffective.
(just physics...)
nope

Are you referring to noise jamming or jamming in general? Because I can see how noise jamming would be ineffective against 'arrayed' radars, but i dont know how other types of jamming work.

If you describe the type of jamming, we could discuss why it is ineffective.

We know the exact position of the RPN.
We know the exact position of the V500R missile flying towards the target, at Mach6.
Our CVK (computer) can easily triangulate the targets real distance in any jamming case...

They may approach low, and pop up suddenly at HARM's maximum range, fire and turn back. A lot depends on terrain, though...

But F-22 is in service, and F-35 is about to join in, and they are considered primary SAM killers by USAF...

I had conversation with one S-300 officer, and he claims that they can fire at F-22 at long distances, up to their maximum range of 90 km (it is S-300PS). However, we strongly disagreed on what RCS those Stealth planes have: he thinks that it is 0,3 square meters, I insisted on something around 0,002 - 0,003 square meters (this figure, in relation to F-22, was named at Russian forum by one RuAF pilot, who has access to classified information). Would be intersting to hear your opinion on the subject.

From what I've heard, from both S-300 officer, and from ECM guys, it is not so: S-300 is suseptble for jamming, although much less so than any other type. Even heard opinion of one French fighter pilot, who claims that they have no problem suppressing S-300, if necessary, although what is meant by "suppressing", remains unclear. Also heard that new S-400 has far, far better jamming resistance, due to ability to rapidly change signal polarisation, that's why Russian military so happy about this system, not because of its longer range.

Update - hand checking the coordinates, the position update/velocity agrees, so if the cursor values are as expected, then this is a GoogleEarth display error with their scale display. I have reported the discrepancy.

Some of the velocity drops during aircraft/evasions/descents look a bit unusual though, and I'm unsure of some of the missile acceleration behaviour.

This seems an unlikely velocity profile, and there is a considerable difference between the reported 'speed' and the displayed scale.

Other tracks produce similar profiles and discrepancies in scale/value. I wonder if the speed/scale is partially where the scale only reports ground speed, but the flight path also allows for changes in altitude? However, this isn't 'all' the problem as the SU9 also has 1320km/h peak reported on an 1187km/h scale. (Allowing for spherical coordinates (19871m altitude on 6378000m earth radius) only increases the 1187 'ground coordinate velocity') to 1190km/h, so there is/was an error of some kind somewhere).


I cannot follow it...
nope

Please describe the problem again.

The SAMSIM only sends coordinates, and timestamp to Google, so any speed value is calculated from it.
