photography of evealed that 2 5X1
Zelenogradsk HF DF Facility (Zelenogradsk Radio Communications Receiver
Station, I land Vnukovo Imo'/DF Facility I I are 25X1
complete an apparently operational. Limited interpre a i i y o the
photography precluded accurate mensuration of the antenna elements at both
facilities.
2. The Vnukovo facility is similar to the Zelenogradsk facility.
The control buildings are similar in appearance. Each facility has a
circle of approximately 52 masts with similar mast spacing. However, no
radial ground system or inner circle of masts were observed at the
Zelenogradsk facility.

4. Zelenogradsk Imo'/DF Facility consists of a central control building,
an inner circle of approximately 52 masts, and 'a circular perimeter fence
(Attachment l), An exact determination of the number, height, and separa-
tion of the masts cannot be obtained from available photography. 25X1

5. Vnukovo HF/DF Facility consists of a central control building,
an inner circle of masts of an undetermined circumference, an outer circle
of approximately 52 masts, a radial ground system, and a circular peri-
meter fence (Attachments 2 and 3).

6. The lack of photography of good inter-
pretability precludes a description of the inner circle of masts as to
number, height, circumference, and spacing, as well as measurement of
heights for the outer circle of masts (Attachment 3).

7. The Puchkovo Radio Communications Receiver Station I 25X1
at 55-29-30N 037-15-00E is associated with the Vnukovo HF DF
Facility. The two cable-connected facilities are 0.5 nautical miles apart
and derive their support from a centrally located support area (Attachment
2). The Puchkovo station consists of eighteen 2-2-2 fishbone antennas,
six horizontal dipole antennas, a central control building, and a building
under construction. Salient features of the HF antennas at the Puchkovo
station are given in Table 1 (Attachment 4).
8. The separately secured support area (Attachment 2) consists of two
barracks, one administration building, two storage buildings, one heating
plant/steamplant, approximately eight support buildings, and an athletic
field.
9. This project is considered to be complete. Any further inquiries
should be directed to NPIC/IEG/MSD/DMEB, IDS Code 143,
