ANALYSIS BASED ON 7 NOVEMBER 1966 PHOTOGRAPHY
MODIFIED ZSU-23/4 FIRE-CONTROL RADAR
1 NOVEMBER 1966 AND 1 MAY 1961 MOSKVA PARADES
In response to the DIA requirement DIA-17-
67 (ST), the following information has been com-
piled and is an update of the analysis of the ZSU-
23~4 fire-control radar previouslypublished. 1/
This update is comprised basically of infor-
mation derived from photographs
of 7 November 1966 numbered
which is to date the best quality photography
(Figure 1) available of the drive mechanism
assembly on the original radar model, and
photography of 1 May 1967, which
shows several modifications which have been
effected in the radar drive assembly (Figure 2).
FIGURE 1. RIGHT SIDE OF THE FIRE-CONTROL RADAR,
7 NOVEMBER 1966.
Photograph-(Figure 1) shows the ex-
terior face of the elevation drive mechanism is
a stationary cover plate, rigidly secured by 13
fasteners, not including those along its bottom
edge (Figure 3). These fasteners appear to
secure this plate to a seatdesignedforthis pur-
pose. The seat ends at the outer ends of the
radial cut on each side, then turns back under the
circumferential edge, possibly forming a semi-
circular seat. The bottom edge of the cover
plate incorporates a cutout which turns up and
around the optical boresight calibrator. This
bottom edge does not appear to make contact

with the primary casting along the previously
reported radial cuts, The 8 or more fasteners
along this edge could secure a backing plate to
the cover plate. This would then serve as a
stiffener.
The cutout mentioned above reveals a possi-
ble rotating plate which may have radial cuts
similar to the cover plate, or it may possibly
be completely circular.
Some additional details of the optical bore-
sight calibrator were observed and are depicted
on Figure 4.

- shows certain modifications in the
area of the drive mechanism assembly (Figure
2). Specifically, these modifications consist of
the elimination of the previously reported stop
plate, the addition of a plate covering the cutout
described above, and the change from con-
toured cover plates (Figure 3) to flush-type
plates (Figure 5) on the lower portion of the
assembly. Of these modifications, the elimi-
nation of the stop plate is the most significant,
as this would require a new casting for this
entire assembly and would negate any exter-
nally visible need for the radial cut design of
the upper portion of the assembly.
