RUSSIAN AERIAL TORPEDO DIMENSIONS
This report presents the results of a series of size determinations
done on a USSR Aerial Torpedo imaged in a group of unidentified photos
submitted to this office by RR/TM.
Several methods of analysis were used as a means of cross checking
findings. These methods were as follows:
1. A simple measurement based on the assumed height of people
imaged in the photography, coupled with an arbitrary allowance for
image foreshortening.
2. Analysis based on the determination of aircraft and torpedo
orientation achieved by establishing the mathematical relationships of
cowl height to width coupled with graphic analysis.
3. Establishment of perspective vanishing points and subsequent
extensions to establish a plane of measurement.
4,' Iconographic study of a true scale model of the imaged air-
craft and measurement therefrom.
All of the above listed methods yielded answers that agreed with
each other to within approximately plus or minus 3%.
Torpedo diameter is determined to be 18_".
Torpedo length is determined to be 1816".
The above dimensions were given to the requester. This memorandum
is for record only.

MILITARY ACTIVITY IN KAN-HSIEN AREA, CHINA
A study of erial photography reveals considerable new
construction activity in the military camps in the immediate vicinity of Kan-
Hsien, China (25?52'N, l]J.?51'E) (Figures 1 & 3), A comparison with earlier
photography (October 1954) also shows that the city is becoming more important
as a transportation center as evidenced by new motor vehicle servicing facilities
and several new bridges being constructed across the Kung and Chang Rivers, which
join to form-the Kan River just north of the city (Figures 2 & 3),
Military Camps - Eight small scattered military camps, with a total area of
approximately 0.61 square miles, are located within a i* mile radius of the
center of Kan-Hsien. The most extensive, and also, the newest groups of
military buildings are located along the western edge of the city within the
area bounded by the pronounced curve in the Chang River just before it joins
the Kung River. An older military area is located immediately south of the
city. A few new buildings have also been added to this older area since
October 1954.
25X1 A total of approximately 300 buildings, ranging in size from small storage
I
sheds (25' x 20') to-large, multistoried, administrative-type buildings
25X1 was tabulated as belonging to the military complexes around Kan-Haien?
Of this total approximately 70 of the buildings were constructed since October

1951 A conservative estimate of the total plan area for all ri_].itary .
buildings in the Kan-Fsien arena would amouunt to about 1,000,000 square
feet, of which approxitrsately 260,000 square feet have been constructed
since October 1954. A very large proportion of these new buildings were
the common, s:Lngle-story rectangular barracks or warehouse type. The
remaining newly constructed buildings were vehicle maintenance bui.ldi.ng;sr.
support buildings, irregular-shaped administrative buildings,, ate. The
scattered areas of new military buildings are shown on Figure 2,
These military establish ents around Kan-Heien are probably for
supply support and security purposes rather than for training; purposes.
No extensive infantry or artillery training grounds were detected
associated with these military camps. Also, no defenses were observed.
Transuorta Lion - Road and bridge improvements shown on recent photography
will soon make Kan-Hsien accessible by motor vehicles from nearly all
directions (Figure 2). In October 1951 one pontoon bridge (A) and one
ferry crossing (B) provided access to the east across the Kung River.
Another pontoon bridge (C) crossed the Chang River to the southwest,
providing access to the abandoned Kan-Chou airfield (Figure 3), The
city was accessible from the northwest by one ferry crossing (E) and
one pontoon bridge across the Chang River (F),
In the January 1956 photography, three new bridges weie under
constriction. One of these bridges will be a pontoon bridge (Ii),
whereas, the other t 3o bridges will be permanent high-level structures

(D and E) with ranch greater traffic capacity than any of the pontoon
bridges.
The pontoon bridge at A has been relocated about 260 feet upstream.
The bridge at B was under construction in October 1951., and the most
recent photography revealed that very little progress in construction
had been made during the in-.ervening period. Although piers had already
been installed in the earlier photography, evident]'..y, priority for its
completion mast have changed. Instead, a temporary pontoon bridge was
placed across the Chang River at E (fo arly a fern crossing), and
construction of a major permanent high level structure started.
January 1956 this bridge with a roadbed approximately 35 feet wide was
between one third and one-half completed.
Recent photography shows a new pontoon b ridge being installed
parallel to the older pontoon bridge at F. Since there are no major
highways on the north bank of the river at this point, it is suspeCt.
that this new pontoon bridge will simply replace the older bride,
which appears to be in need of repairs, rather than add to the capacity
of this crossing.
The new pontoon bridge at D is about two-thirds completed. New
approaches and new roads in the vicinity indicate that this bridge
may be intended as an alternate route, or actual short-cut, to the
highway leading to Shy Yu west of Kan-Hsien,

The improved accessibility of Kan-Usien by highway should increase
its importance as a transportation center. The existence of a motor
pool near the south and of town, and the establishment of what appears
to be new motor vehicle repair shops adjacent to the barracks area west
of town, would also indicate an increased interest in motor vehicular
traffic through this area.
Considerable river traffic h.is been noticed on b)th the Chi and the
the Kung Rivers. Open storage yards along the river banks indicate
that Kan-Hsien may be an important trans-shipping point.
No new activity was observed at the abandoned Kan-Chou airfield,
about 1l miles southwest of Kan-Hsien.
