NEW TYPE OF ANTENNA IDENTIFIED AT TYPE III-X
LAUNCH CONTROL FACILITIES IN THE USSR (TSR)
(TSR) Continuing analysis of the communications antennas at the new-type Soviet
launch control facilities (LCFs)- type III-X silos-reveals that the guyed mast with two
horizontal booms, each supporting afive-element Yagi antenna, and designated as PE-EL-
O1 (Figure 1) has not been deployed at type III-X silos since approximately early- to mid-
1977. The antenna that has been deployed at type III-X silos since mid-1977 is the PE-EL-02
(Figure 2), which is the same type of antenna as that previously identified at Pervomaysk
and Khmelnitskiy ICBM Complex Command Post Bunkers as well as at Yoshkar-Ola
Launch Control Facility B, which is not anew-type LCF.
(TSR) The PE-EL-02 antenna is a guyed mast approximately 26 meters high with a 9-
meter diagonal appendage (boom or spar). The appendage is tilted approximately 15
degrees from the vertical. The type and number of elements on the boom cannot be deter-
mined. In addition to the differences in number and position of the booms between the PE-
EL-Ol and PE-EL-02, another distinguishing characteristic is the number and spacing of
concrete blocks around the base of the mast (Figures 1 and 2).
(TSR) The function of the PE-EL-02 is probably the same as that of the five-element
Yagi antenna (PE-EL-Ol). This is suggested by the fact both types of antennas have been
identified within ten of the 12 SS-17, -18, and -19 ICBM complexes. Just prior to the change
from the PE-EL-Ol to the PE-EL-02 antenna, it was also observed on photography that
beginning in late 1976 hardened Hook and Plus antennas were no longer being deployed at
SS-17, -18, or -19 ICBM launch sites.
(TSR) The switch from the PE-EL-Ol antenna to the PE-EL-02 antenna along with the
apparently discontinued deployment of the hardened Hook and Plus antennas may indicate
a change in the deployment concept of phase II antennas.
