Was browsing for more info on the elusive SA-4/3M8M3, instead I found these:

Also, I'd be very interested in any information you could provide about the SA-4, such as the reference sites you used while creating the system. I've been unsuccessful so far in finding any truly in-depth information regarding the SA-4, or the 3M8M3.

The best sites, that I found, are at the bottom of the SAMSIM homepage.

The pictures were shot at Hungary:

Hungarian Air Defense Museum, Zsámbék (Volhov, Neva, 1S12 Long Track)

12. Arrabona Air Defense Regiment, Gyor (1S32 KRUG)

Army History Museum and Park, Kecel (Vega, Shilka)

About the SA4, I got the usual (~1500 pages of) Hungarian language manuals...

This page contains a link to an interesting video about that S-200 site: http://www.fortifikace.net/soubory/rapotice_video.mp4.

Can anybody identify the instrument that appears at 2:50?

Certainly.


That is the leftmost round instrument of the K9 cabin. (It is not simulated)
In this cabin, the commander of the site were guided the firing batteries.

Ugh.. It's always a language I can't read, lol. After spending a few more hours Google diving, I'm really surprised by the lack of interesting information. It seems like every site I find that actually mentions the 2K11-M1/SA-4 just repeats what all the others say. And so far the only internal images I've found are pictures taken by someone who thought it'd be great to place a massive watermark of his email address right through the middle. Pretty sad as they're up close pictures of some of the station panels..

I am however rather pleased with some of the pictures I found of the missile, a performance chart, and pictures showing how the radar deploys/stows.



Also, two new questions. First, after the initial launch of the missile, are the solid fuel boosters ripped off of the 3M8M3 missile, or is there a system to release them? Secondly, what does 1 do?

Extremely good find!!!
Everybody should watch it.

1, SNR Frequency selector switch.
You can find the same at the Volhov "Z" panel.

Usually guarded so one frequency was used in peacetime, and another in wartime.
(In case the enemy listens before the hostilities begun.)

That's a pretty good trick. Does the Gammon have that ability too?

All the WarPact, (and I assume) that Western systems were capable of it.
(You need the capability to tune your frequency away, if you are close to another similar system.)

Lets discuss 2K11-M1 KRUG-M1 (SA-4B Ganef) specific issues here...
