The construction of the double ring-road around Moscow (length of 900km, including 56 firing position) was completed in 1955, the next logical step was Leningrad.
Due to geographic conditions only one ring was planned.
The 300km long ring-road, and 34 firing positions were completed by 1958.


To limit huge expenses, decision was made to place Volhov/Neva batteries into the prepared firing positions instead of fielding the S-50 version of the Berkut around Leningrad.

Now we have some ideas what these SA-1 and SA-2 systems would face...

A chilling read:
http://nsarchive.gwu.edu/nukevault/ebb538-Cold-War-Nuclear-Target-List-Declassified-First-Ever/


Quote:
Washington, D.C., December 22, 2015 - The SAC [Strategic Air Command] Atomic Weapons Requirements Study for 1959, produced in June 1956 and published today for the first time by the National Security Archive www.nsarchive.org, provides the most comprehensive and detailed list of nuclear targets and target systems that has ever been declassified. As far as can be told, no comparable document has ever been declassified for any period of Cold War history...



Quote:
The SAC document includes lists of more than 1100 airfields in the Soviet bloc, with a priority number assigned to each base. With the Soviet bomber force as the highest priority for nuclear targeting (this was before the age of ICBMs), SAC assigned priority one and two to Bykhov and Orsha airfields, both located in Belorussia. At both bases, the Soviet Air Force deployed medium-range Badger (TU-16) bombers, which would have posed a threat to NATO allies and U.S. forces in Western Europe.

A second list was of urban-industrial areas identified for systematic destruction. SAC listed over 1200 cities in the Soviet bloc, from East Germany to China, also with priorities established. Moscow and Leningrad were priority one and two respectively. Moscow included 179 Designated Ground Zeros (DGZs) while Leningrad had 145, including population targets. In both cities, SAC identified air power installations, such as Soviet Air Force command centers, which it would have devastated with thermonuclear weapons early in the war...


Quote:
To deliver the weapons to targets, SAC would use bombs and missiles. For bomber delivery systems, SAC would use B-47s, based in the United Kingdom, Morocco, and Spain, and intercontinental B-52s, which were just beginning to be deployed in the continental U.S.

SAC listed four missile types for delivering nuclear warheads: the Snark, the Rascal, the Cross Bow, and IRBM [Intermediate Range Ballistic Missile]. The Snark, an early intercontinental ground-launched cruise missile, was only briefly deployed, during 1959, because it was a fiasco (areas in the Atlantic Oceans where the missiles crashed were called Snark infested waters). The Rascal (replaced by the Hound Dog in 1958) and Cross Bow were both bomber-launched missiles, with the Crossbow targeting radars.

President Eisenhower had made IRBMs, along with ICBMs, a national priority, but in 1956 the IRBM was still projected for the future. With a range of up to 1700 miles (1500 n.m.), deployment overseas would be necessary and the Air Force envisaged stationing them in the United Kingdom, although talks with the British had yet to begin. The Air Force would eventually deploy liquid-fueled Thor IRBMs in the United Kingdom during 1960-1963, while Jupiter missiles were stationed in Italy and Turkey during 1961-1963 (removed as part of the Cuban Missile crisis settlement).[12]

SAC also identified the atomic bombs and the thermonuclear weapons that would be mated to the delivery systems. They would be Mark 6 (B and C) atomic weapons and Mark 15, 27, and 36 thermonuclear weapons. The latter had extraordinarily massive explosive yields: MK 15: 1.6 to 3.9 megatons; MK 27: 2 megatons, and MK 36: 9 to 10 megatons. These compare with the size of the U.S. nuclear tests in Operation Castle during 1954, in which actual explosive yields (not counting one fizzle) ranged from 1.7 to 15 megatons...

I will answer Alien_MasterMynd question on GSh for C-25 Berkut system in this thread.

C-25 actually had an additional pair of auxiliary wide beam receiving antennas installed: one for elevation and one for azimuth. Here are the pictures from the 1967 C-25 Mod2 field testing album:

Far view, both GSh system antennas visible near their respective main channel elevation and azimuth antennas:



Close side view on the GSh-epsilon antenna:


Close side view on the GSh-beta antenna:



Shelves containing GSh circuits: It must be noted that GSh wiring in C-25 was done in a different way than in C-75 or C-125 (without using log amplifiers); this allowed to use GSh while in SDC mode in Berkut simultaneously (Voklhov/Neva could not use GShV/GShN in SDC mode).



And finally, amazing photos showing angle-jamming target in indicators at various ranges (d= 40, 30, 20, 15).

Can you drop me this album?
Im also interested in any guidance panel (and panel screen), and also any outside photo of the bunker.

Here is the Yandex download link.

It's from the History of PVO webpage.

Can't help too much. There are two old albums with some low-quality panel photos on the same History PVO webpage.

Original Berkut C-25

Berkut mod 1(?) after second upgrade (1961, colorized)

Some hard to find information about the real expenses of first Soviet SAM systems...
