PART TIME AIR WARNING RADAR SYSTEM, USSR
1. Twenty-seven facilities which are a part of the PART TIME
Air Warning Radar System in the USSR have been identified on KEYHOLE
photography. Twenty of these facilities have ribbed radomes 23
meters (75 feet) in diameter and PART TIME radars, which are prob-
ably inside the radomes. Six of the remaining facilities have fixed
data receiving antennas collocated with TALL KING radars. The
seventh facility has the fixed data receiving antennas but no col-
located TALL KING.
2. This report includes a location map and tabular listing of
the 27 facilities and annotated photographs of selected facilities.
3. Twenty-seven facilities which are a part of the PART TIME
Air Warning Radar System in the USSR have been identified on KEY-
HOLE photography since 1964 (Figure 1 and Table 1). Twenty-one of
these facilities are deployed along the northern and southern
borders of the USSR, and the other six are deployed in the interior.
4. A typical PART TIME radar facility consists of a ribbed
radome 23 meters (75 feet) in diameter, a PART TIME radar, which is
probably inside the radome, and three horizontal fuel storage tanks
(Figure 2).1 The radar has never been observed on KEYHOLE photog-
raphy. The associated radome is unusual in that it has six circular,
unidentified objects on top. Other radomes 23 meters (75 feet) in
diameter observed in the USSR on KEYHOLE photography do not have
these objects.
5. The radar data acquired by the PART TIME radar is transmitted
to a remote recipient which is probably collocated with TALL KING
radars. The PART TIME radars deployed in the north transmit their
data to cut parabolic data receiving antennas 10 meters (33 feet) in
diameter, nicknamed RAG TIME, which are collocated with TALL KING
radars (Figure 3). The PART TIME radars at Kapustin Yar and the
two on the USSR-Mongolia border probably transmit their data to
antennas 18 meters (60 feet) in diameter (Figure 4).
6. When the air warning radar facilities and the azimuths of
the data receiving antennas are plotted on a map, a series of
triangles is produced (Figure 1). Two PART TIME radar facilities
and one TALL KING radar facility appear to form one triangle. This
pattern suggests that in those areas of the interior and far eastern
USSR where only one or two facilities could be identified, a second
and/or third facility may exist which would complete the triangular
pattern. However, the lack of current KEYHOLE photography covering
these areas precludes identification of these facilities.
7. There are indications that the system may he undergoing some
type of modification. Between May and October 1971 the RAG TIME
antennas at Shoyna were removed, and in October 1971 the radome at
Malaya Nes had been partially dismantled.
8. The 27 facilities listed in Table 1 have been identified as
components of the PART TIME Air Warning Radar System.
