This report- introduces an NPIC series on
Soviet-type KRUG high-.frequency direction-
finding (HF DF) antenna array installations.
The series will consist of short but detailed in-
dividual reports using a standard format, cover-25X1 D
ing all 31 installations containing KRUG antenna
25X1 D arrays which have been identified

identified on future photographic missions. Each
report will be based on the best of the latest
photographic coverage available. It is proposed
that when significant changes are identified on
photography, superseding reports will be issued.
Capabilities of the KRUG Antenna
The KRUG array is a versatile antenna
system that can be adapted to perform a variety
of functions. A partial listing of these reported
functions 1/ includes:
25X1 D

Frequency. . . . . . . 2 - 20 mcs
Range. . . . . . . . . . 5,00U nautical
Bearing ...... -. 360 degrees -
Accuracy . . . . . . 1.0 degree
Each report will include basic data on the
installation, set in boxes at the top; a brief
but comprehensive photographic interpretation
of the installation; and an annotated photograph
from the referenced mission. Notes on the items
included in the basic-data boxes are given below:
Installation Name. Installations will be
carried by Target Data Inventory (TDI) or
Bombing Encyclopedia-(BE) names unless these
conflict with NPIC usage.
Geographic Coordinates. Coordinates will
be given in degrees, minutes, and seconds as
plotted by NPIC on the referenced map or chart,
usually the Series 200 US Air Target Chart.
NPIC Target Number and BE Number. Each
of these is unique to the installation and con-
sists of the WAC number plus identifying digits.

Photography. This box contains full photo-
graphic references for the coverage on which
the report is.based.
AD Area. This box contains a tag identi-
fying the air defense (AD) area in which the
installation is located. The tag is based on a
system devised by NSA which divides the USSR
as shown in Figures 4 through 7.
The first element of the tag, the letter F,
indicates an electronic installation. The second
element, also a letter, indicates the air defense
district- in which the
as follows:

These districts have in turn been divided
into zones as indicated by the first digit in the
tag, and further subdivisions are indicated by
the second digit..
Only a 2-letter country indicator will be used
in the'box when installations lie outside the USSR.
References. This box contains data oh the
map or chart used for plotting the location of the
installation and a citation of this introductory
report.
Requirement. This box contains the re-
quester's requirement number.
items covered in the boxes at the head of the
-report, as much description of the installation
as possible will be given. The subject headings
in this section were selected after detailed
evaluation of a number of individual facilities
to ensure a comprehensive profile of any given
facility.
These
headings will always occur in
the same
order;
when any particular category
does not
apply
to a. given situation, it will be
omitted.
This
omission indicates only non-
applicability; negative information, such as
the absence of security measures or the lack
of activity, will be noted when observed. The
information that will be included under some of
these headings is explained below; the other
headings are self-explanatory but are included
to indicate their place in the standard order
of entries and also to suggest the broad scope
of photographic interpretation that will be
accomplished for each facility. All measure-
ments must be-considered approximate.
Location. The distance and direction from
the town the installation was named for.
Function.
Support Components. The buildings. and
structures -in the immediate vicinity of the
operational components will be listed here.
Usually they will not. be annotated on the photo-
graph.
Security.
Vegetation & Terrain.
Support Facilities. This entry describes
a separate support facility other than the support
components situated in the immediate vicinity
of the operational elements of the installation
and already described above.
Associated Facilities.
