SUBJECT: Evaluation of Photography of the SA-3 Guidance Radar at
Gryaznaya Guba, Mys Set Navolock and Ostrov Nargin
REFERENCE: (a) Requirement C-S14-80,987
(b) CIA/PID Project C 140-64
1. This memorandum is in response to your requirement dated 16 January 1964
requesting a photo analysis be made of the latest photography available of
Gryaznaya Guba SA-3 Guidance Radar (LOW BLOW), and to indicate if there were any
significant disagreements pertaining to dimensions or antenna orientation as
25X1 C reported by
In addition to your requirement a comparative study of component parts of Ostrov
Nargin (Baku), Mys Set Navolock and Gryaznaya Guba SA-3 Radars (LOW BLOW) was
made to determine if there were any new developments in similarities.
2. No major or significant disagreement was found in report 25X1C
as far as content was concerned; however, additional pertinent intelligence
could have been reported. The following observations were made by this analyst
as a result of a comparative study of the three radar sites with new1photography
obtained since last reported (M/EB 461/63, 29 October 1963).
All three sites now positively contain seven identical components:
two (2) troughs (similar to FAN SONG type troughs), one (1) cut paraboloid
25X1C (referred to by as a square dish), one (1) cut paraboloid with feed,
25X1C one (1) independently mounted feed and the two(2) (unidentified at this time)
stacked cylindrical sections (referred to by as tubes). The chassis,
evident on the LOW BLOW radar at Ostrov Nargin SA-3 may also be present at the
other two sites; however, shadows preclude their precise interpretation (refer
to Figure #1).

The following additional observation may be taken into consideration
with re and to the operational sequence of the radars. It is generally felt
25X1C by that the operational position of the LOW BLOW radar is when the
two troughs are positioned at a 45? angle to the ground and the cut paraboloid
with feed is present at the apex of the two troughs. However, it was observed
in this analysis that every time this position was noted, the missile launchers
25X1D were either In one instance at the
Ostrov Nargin Site even the radar was canvas covered in this position. Also,
the troughs were in this position at Fili Airfield while being assembled for
possible later testing. It was further observed that when the troughs were
parallel with the ground and situated at a 90? angle to each other, the cut
paraboloid with feed in a lowered position and the independently mounted feed
in a raised position the missile launchers were occupied and in.one case
actually poised. One possible exception to this is on winter photography, the
launchers were canvas covered. It is also noted that at all times, without
exception, the independently mounted feed was always positioned pointing toward
the cut paraboloid whether it was in its raised or lowered position. This
position of the feed might possibly be the operational situation of the radar.
All components have the ability to move in one way or another. The
cut paraboloid with feed revolves independently when in a raised position.
The lattice mast mounted independent feed may be raised or lowered. The.single
cut paraboloid was seen in alternate positions,opossibly slaved but not attached
to the independent feed. The troughs have a 45 angular movement and the
unidentified stacked cylindrical sections may move from a horizontal to a
vertical position. The whole radar apparatus is mounted on a heavy lattice mast
which in turn is attached to a wheeled frame.
25X1C and NPIC both used the component parts visible at Fili
Airfield for a mensuration guide and only a difference was noted.

contacted on extension 2705 should you have further questions regarding this
project.
4. This project is considered to be complete.
