PROBABLE HARDENED ANTENNAS AT TYURATAM MISSILE TEST CENTER
AND DOMBAROVSKIY ICBM COMPLEX, USSR
1. Seven new types of probable hardened antennas in various stages of construction have been
identified at the Tyuratam Missile Test Center and the Dombarovskiy ICBM Complex. These probable
hardened antennas are associated with launch sites for the SS-X-17, SS-X-18, or SS-X-19 missile systems
and the type IIIX probable control sites.
2. This report includes a location map, 11 annotated photographs, and tabular data.
3. Seven new types of probable hardened antennas are under construction at the Tyuratam
Missile Test Center (TTMTC) and the Dombarovskiy ICBM Complex, USSR. The pattern for
deployment of these antennas is not readily apparent since the numbers and types of antennas vary
from site to site.
4. The TTMTC antennas are at launch sites in launch groups R and S and sites T1 and T2
(Figure 1). These sites are associated with the research and development of the SS-X-17, SS-X-18,
or the SS-X-19 missile systems. The antennas are also at the two type IIIX probable control sites,
R1 and S4, at TTMTC.
5. Additionally, three types of these antennas have been identified at a deployed ICBM
complex, Dombarovskiy. Two of these antennas are at type IIIX probable control site 75 and one
is nearly complete at type IIIF launch site 73.
6. The identification of these seven geometric features as probable hardened antennas is based
on their association with a known hardened antenna (herringbone) and the presence of cable trenches
from the geometric shapes to the silo area.
7. The operating frequencies and propagation azimuths of these seven probable hardened
antenna types have not been derived because of the lack of technical information on Soviet hardened
antennas.
8. The seven new types of probable hardened antennas, for ease of reference, have been
arbitrarily designated as: hook, dome, ell (previously designated as a hardened vee, type III), circular,
wedge, plus, and quad-tri. These designators have been assigned on the basis of the current physical
configuration of the probable antennas.
9. Examples of each type of probable hardened antenna are shown in Figures 2 through 8.
Representative examples of the antennas as they relate to one another within a launch group are
shown in Figures 9 through 12. Measurements are necessarily preliminary because the construction
is still incomplete.
10. The type and number of the antennas and the associated launch sites where they have
been identified are presented in Table 1. The dates of first observation of these antennas are given
in Table 2.
11. The most numerous of the seven antenna types is the hook (Figure 2). As of October
1973, 13 of these antennas have been identified at launch sites at TTMTC within launch groups
R and S and at sites T1 and T2. This antenna was first seen under construction at type IIIF launch
site R8 in October 1972. All were still under construction in October 1973.

12. The hook consists of three linear trenches, in a hook-shaped
pattern. The antenna appears to be connected to the silo headworks by a cable trench which intersects
the longest of the three trenches.
13. Eight domes have been identified at TTMTC and one at Dombarovskiy launch site 73 (Figure
3). Seven of the TTMTC antennas and the one at Dombarovskiy are at type IIIF launch sites and
the eighth is at type IIIX probable control site R1, TTMTC. The first antenna was seen under
construction at launch site R10, TTMTC, in October 1972. All eight antennas now appear to be
almost externally complete.
14. This antenna consists of a recessed dome encircled by a probable concrete ring. The ring
appears to be flush with ground level whereas the top of the dome appears to be slightly below
ground level. Prior to completion, a dark-toned substance is applied to the dome and the ring. A
cable trench extends from the antenna; however. the termination point has not been determined.
At launch site T1 and T2 a small section of circular conduit was seen in the cable trench next
to the concrete ring. This is the first discernible evidence of conduit being installed in the cable
trench. At probable control site R1 the antenna appeared to have been covered by a dark-toned
circular cover. This cover may subsequently appear on the other dome antennas and could be for
environmental protection.
1.5. The ell (Figure 4) has been identified at four launch sites and the two probable control
sites (all at TTMTC) and at the Dombarovskiy probable control site. There are two ells at TTMTC
probable control site R1 and two were begun at launch site R4. The two at site R4 were started
in November 1972, but no construction activity has been seen since that date. The first ell antenna
was seen under construction at probable control site R1 in July 1972. The antennas at TTMTC
are being constructed outside the site security fence; however, the antenna at Dombarovskiy is within
the fences.
1.6. The ell consists of two sets of four long parallel trenches that intersect at right angles
to each other to form the apex of the L-shaped pattern. The length of the trenches and the separation
between them vary from antenna to antenna.
These antennas are connected to the site area by a. cable trench from a point near the apex.
1.7. Two circular antennas have been identified in launch group S at TTMTC and one at
Dombarovskiy probable control site 75. This antenna was first seen under construction at TTMTC
probable control site S4 in July 1973.
18. The antenna is constructed in a circular dish-shaped excavation
At probable control site S4 a cable trench extends from the edge of the antenna to an
excavation next to the silo apron (Figure 5).
Probable Hardened Wedge Antenna
19. The wedge has been seen at the two probable control sites, R1 and S4, at TTMTC (Figure
6). This type of antenna was first seen under construction at site R1 in October 1972.
20. The antenna is constructed in a wedge-shaped excavation with the wider end of the wedge
closer to the site. A cable trench extends from the wide end to the site apron near the silo headworks.
The antenna at probable control site Rl was being covered with a dark-toned substance in October
1.973. A probable concrete trough was seen within the wedge-shaped excavation at probable control
site S4, also in October 1973.

Probable Hardened Plus Antenna
21. The plus has been identified at four launch sites in launch groups R and S at TTMTC
(Figure 7). The first antenna was seen at type IIIF launch site R11 in May 1973.
22. The plus antenna consists of two trenches which intersect at right angles at the middle
of the two trenches. A cylinder is in a vertical position at the center of the plus.
A cable trench extends from the center of the plus and
will probably terminate near the silo headworks. At launch site R4 and R11 a probable concrete
trough has been constructed within the plus-shaped trenches.
Probable Hardened Quad-Tri Antenna
23. The quad-tri has been seen at the two type IIIX probable control sites at TTMTC (Figure
8). Four of these antennas are at site R1 and one is at site S4. Construction for the first of these
antennas was seen in October 1972.'
24. The quad-tri antenna begins with a gridwork structure at the bottom of a square excavation,
a vertical cylinder with an approximate outer diameter of 10 feet in the center of the gridwork,
and five vertical uprights along each side of the gridwork. Four triangular structures are then placed
around the cylinder with the apex of each triangle pointing inward toward the cylinder. Next, the
triangles are attached to the vertical uprights. Then the excavation is backfilled. A cable trench extends
from one corner of this antenna to the edge of the silo apron.
