This report presents the results of a comprehensive study of the
Chinese Communist aircraft industry based on photographic interpre-
tation of both airframe and aircraft engine production facilities. The
plants are described separately in the report; for comparison purposes,
perspective drawings of the various test facilities at the plants are
presented together in a separate section. The plants included in this
report may not constitute the entire Chinese Communist aircraft in-
dustry; however an extensive search of photography of the Chinese
mainland from indicates that at least the greater part of
the industry is included here. This report has been prepared as
project C-1782/63 in response to CIA requirement number C-DI3-
80, 867.

The Chinese Communists, with technical
assistance from the USSR and the European
Satellites, began development of a domestic air-
craft industry in the early 1950s. The first fa-
cilities for aircraft production were developed
by rehabilitating and expanding older facilities
previously utilized as aircraft repair andmain-
tenance depots. The installations at Shen-yang,
Nan-chang, and Peiping were converted to pro-
duction facilities in this way. The Chu-chou
Aircraft Engine Plant was probably converted
from a World War II arsenal.

During this period of rehabilitation and ex-
pansion, the Chinese Communists apparently
realized that additional and more modern fa-
cilities would be needed to supply their future
aircraft needs. The importance which the
Chinese Communist regime attaches to the
aircraft industry is apparent from the ambitious
program they have initiated for the construction
of new and modern aircraft plants. The
Ha-erh-pin Aircraft Engine and Airframe Plants
and the Ku-tien-tzu Aircraft Assembly and Re-
pair Plant were probably the first totally new

he installation was identified as
an aircraft assembly and repair plant, containing
approximately 731, 31,400 square feet of floorspace.
Later photography, from

showed no apparent change in facili-
ties or floorspace at the plant. The presence of
airframe crates and smaller component crates
in the plant area indicates that the plant proba-
bly assembled aircraft from shipments received
from the Soviets.
The plant appears to be a major repair fa-
cility for both airframes and aircraft engines;

this interpretation is supported by the large
number of aircraft observed at the airfield and
on the parking ramp adjoining the plant. The re-
pair of aircraft engines is evident from the pres-
ence of an engine test building and an aircraft test
revetment. The engine test building (item 6, Fig-
ure 7 and Table 4) has three projecting wings, two
housing single test cells and one housing a double
test cell (Figure 31). One wing includes a con-
trol and instrumentation section.

The adjacent Ku-tien-tzu Airfield has a 25X1
northeast/southwest concrete runway measuring 25X1
6,400 by 200 feet. The runway is served by a
full-length parallel taxiway with four crossovers
and numerous hardstands and parking/assembly
aprons. Repair hangars are also present at the
airfield. At the time of 39 25X1
FAGOT/FRESCO and 3 BEAGLE were visible at
the airfield.

Nan-chang Airframe Plant, designated in the
TDI as Nan-chang Aircraft Repair and Assembly
Plant, is located adjacent to the Nan-chang New
Airfield 3.5 nm southeast
of the center of Nan-chang (Figures 1 and 8).
The plant is served by both road and rail.
This plant was identified as an aircraft
repair and maintenance depot when first photo-
graphed in Later photography of
the plant, from
:::::)hows that the installation contained ap-
proximately 869,975 square feet of floorspace
at that time and was capable of assembly as well
as repair and maintenance of aircraft. A com-

containing approximately 230,025 square feet of
floorspace, which increase the plant's total
floorspace to approximately 1,100,000 square
feet (Figure 9 and Table 5). The additions in- 25X1
dicate that it is now possible for the plant to
fabricate airframes.
The adjacent Nan-chang New Airfield has a 25X1
northeast/southwest concrete runway, which has 25X1
been extended from 5,000 feet in 25X1
to its present dimensions of 7,600 by 230 feet. 25X1
The runway is served by two crossovers and
two taxiways, which connect the runway to a
parking ramp adjoining the airframe plant.

adjacent to Shen-yang Airfield North
Shen-yang Airframe Plant 112 is located
of Shen-yang (Figures 1 and 12). The plant was
formerly known as the Shen-yang Aircraft
Manufacturing Company Plant No 2. It is served
by both road and rail.
This installation, when first observed on
World War II prestrike, strike, and poststrike
photography, was an aircraft repair and main-
tenance depot containing approximately 361,640
square feet of floorspace. This photography
indicates that little or no damage had resulted
from aerial bombardment. Photography ofC
square feet.
4 nm north-northeast of the center
reveals that the original aircraft
depot had been expanded into a modern
plant, capable of fabricating and assembling
aircraft in addition to performing repair
and maintenance. The expansion increased
the total floorspace to approximately 1,586,340
photography from
with that of
ity had taken place during this interval, which
increased the plant's total floorspace to approxi-
mately 1,962,730 square feet (Figure 13 and
Table 7). Additions since include
a subsonic wind tunnel and a gas dynamics fa-
cility consisting of a possible supersonic wind
tunnel and a battery of 15 pressurized tanks,
with bases available for nine additional tanks
(Figure 26). More recent photography of the
airframe plant, from

no apparent change in facilities or floorspace;
some construction activity is evident, however,
on the taxiway at the adjacent airfield.
Shen-yang Airfield North has a north/south 25X1
concrete runway, which has been extended from 25X1
6,600 feet in to its present dimen- 25X1
sions of 9,900 by 280 feet. The runway is served
by four crossovers, one of which is under con-
struction, and by a parallel taxiway which is
being extended to the north. Repair facilities,
parking and assembly aprons, and an aircraft
test revetment (Figure 36) are also located at
the airfield. Nine FARMER, one FAGOT/

Yen-liang Airframe Plant, designated in the
BE as Hsi-an Airframe Plant Yen-liang Airfield,
is located adjacent to the Yen-liangAirfieldC
22 nm north-northeast of Hsi-
L/
der construction on
an, China (Figures 1 and 14). The plant and
the airfield are served by both road and rail.
The airframe plant was first observed un-
(Figures 14 and 15). The buildings com-
pleted or nearing completion incon-
tain approximately 1,470,275 square feet of
floorspace; the buildings that were then in
early or partial stages of construction will con-
tain an additional estimated 1,068,800 square
feet of floorspace when completed (Table 8). 1/
show no apparent
change in facilities or construction status since
indicating that the construction
of this plant is at a standstill.
There does not appear to be a final assembly
hall sufficiently large for the production of air- 25X1
craft of greater than fighter size; however, 25X1
ample space is available at the plant for such
a structure.
The adjacent Yen-liang Airfield will prob-
ably serve the plant as a test and flyaway field. 25X1
The airfield has a northeast/southwest concrete 25X1
runway measuring 8,400 by 230 feet and a full- 25X1
length parallel taxiway with five crossovers.
A firing-in butt and three repair hangars are
located at the airfield. At present there is no
indication of a connecting taxiway between the
airframe plant and the airfield. The alignment
of this taxiway would depend on the ultimate
location of the final assembly hall. Two COLT

shows additions of approxi-
mately 1,046,450 square feet of floorspace, in-
creasing the plant's floorspace to approximately
2,694,025 square feet. Three new buildings
(Figure 16); upon completion these 25X1
buildings will increase the floorspace of the
plant to approximately 3,000,000 square feet.
The installation appears to be in the final stages 25X1

The engine test facilities are housed in the 25X1
test building (item 1, Figure 17 and Table 9). 25X1
This building has four projecting wings, two
containing double test cells and two containing
single test cells. One wing includes a con-
trol and instrumentation section. The four
cells are served by individual exhaust towers
(Figure 27).

Chu-chou Aircraft Engine Plant is located
on the east bank of the Hsiang Chiang (river),
3 nm southeast of the center of Chu-chou
(Figures 1 and 18). The plant is served by
both road and rail.
When first observed on

photography with that of=
shows a substantial
increase in floorspace in the original instal-
lation (Area A, Figure 19), amounting to ap-
proximately 220,500 square feet, as well as the
construction of a new area (Area B, Figure 19)
adjoining the north side of the main plant area.
This new area, which contains an additional
215,800 square feet of floorspace, appears to be
associated with the aircraft engine plant, since
its only access lies through the plant. The
area contains a three-story laboratory, an
assembly/machine shop under construction,
workshops or machine shops, two drive-through
buildings, and five well dispersed storage/
processing buildings. Three of the storage/ 25X1
processing buildings are constructed on aprons, 25X1
possibly concrete, which suggests the handling
of a corrosive-type substance. This area is 25X1
served by a drainage system and an underground 25X1
water reservoir, possibly for the flushing of
spillage or waste.
The engine test facilities are housed in the
test building (item 1, Figure 19 and Table 10).
This building has three projecting wings, two
containing single test cells and one containing a
double test cell. The three wings are served
by individual exhaust towers (Figure 28).

Shen-yang Aircraft Engine Plant and the
adjacent main plant of Shen-yang Arsenal 90th
(41-47N 123-29E; E -1 are lo-
cated next to the Shen-yang Airfield Southeast
in the Ta-tung ward of
Shen-yang (Figures 1 and 22). Both of these
plants are apparently involved in the production
of aircraft engines and will be considered to-
gether in this report as the Shen-yang Aircraft
Engine Plant. The installation is served by both
road and rail.
The Shen-yang Aircraft Engine Plant was
first observed in
on World War II prestrike, strike, and
poststrike photography. This photography shows
that damage caused by the aerial bombardment
of this plant was not extensive, although some
buildings were destroyed. Photography of the
plant from shows
that a complete rehabilitation had been affected
and that newer buildings had replaced some of
the older facilities. The first indication of a
connection between the original aircraft engine
plant and the main plant of Shen-yang Arsenal
90th appeared on
when aircraft engine test facilities were ob-
served within the plant area of the arsenal (items
18 and 36, Figure 23 and Table 12). At the time
of the latest photography, from
the installation contained approxi-
mately 4,065,520 square feet of floorspace.
The adjacent Shen-yang Airfield Southeast

has a northeast /southwest concrete runway 25X1
measuring 6,750 by 275 feet. The runway is 25X1
served by a full-length parallel taxiway with
four crossovers and several parking/assembly
aprons. Repair facilities are also located at
this airfield. Photography from

TEST FACILITIES
The wind tunnel and the gas dynamics fa-
cility shown in Figure 26 are located at Shen-
yang Airframe Plant 112. Both appear to be in
the final stages of construction and are not yet
capable of operation. Other facilities may be
added to enhance research capabilities in the
field of aerodynamics at the Shen-yang plant.
The wind tunnel, a subsonic continuous-flow
type, consists of a control, instrumentation, and
laboratory section (A), a first diffuser (B), a
power section (C), a second diffuser (D), a set-
tling section (E), a contraction section (F), and
a test section (G).
The gas dynamics facility consists of a
building (H) which possibly houses at least one
supersonic wind tunnel, and a battery of 15
spherical storage tanks, with bases available
for nine additional tanks. Each tank has a

The aircraft engine test buildings and the
fuel storage, blending, and control stations have
been two key features in the identification of
aircraft engine plants in Communist China. The
engine test buildings, with the exception of those
shown in Figures 33 and 34, are of the same
basic design; however, since these buildings vary
somewhat in size, configuration, stage of con-
struction, and the number and type of test cells,
they will be described separately.

The engine test building shown in Figure 34
is one of the original buildings of the Shen-
yang Aircraft Engine Plant. Currently under-
going modification, the rectangular building con-
tains six through-type test cells. One of the cells
has been extended, and an enclosed, possibly
concrete blast apron now serves the cell.
The engine test building at the Wu-kung
CIA/PIR-1003/64
Aircraft Engine Plant (Figure 35) appears to
be complete. The building consists of a base
wing for engine servicing and inspection, and
four projecting wings. Two of the wings house
double L-type test cells, and two house single
L-type cells. One wing includes a control and
instrumentation section.
The aircraft test revetment represented in
Figure 36 is located at Shen-yang Airframe
Plant 112; similar test revetments exist at
Cheng-tu Airframe Plant, Ha-erh-pin Airframe
Plant, Ku-tien-tzu Aircraft Assembly and Re-
pair Plant, and Nan-chang Airframe Plant.
The revetment at Shen-yang Airframe Plant 112
is the largest of these and is capable of testing
two aircraft simultaneously. The others appear
to be single units.
The revetments are constructed of banked
earth and appear to be finished with soil sta-
bilizer or a similar hard-surface m,~terial.
The inner rear banks are protected by blast
walls or blast deflectors; the large revetment
at Shen-yang utilizes a deflector and has a blast
wall which divides the revetment into two areas
(Figure 36). The revetments are served by
concrete aprons and control or instrumenta-
tion buildings.
The exact purpose of these test revetments
is not known, but it is believed that they serve
to abate noise during the measurement and cali-
bration of the performance of aircraft engines.

Fuel storage, blending, and control stations
are located at all Chinese Communist aircraft
engine plants except the plant at Chu-chou.
They are of three basic types (Figures 37-41).
Both Type 1 (Figure 37) and Type 2 (Figure 38)
are found at the Shen-yang Aircraft Engine
Plant. Type 3 is shown in three separate stages
of construction; the first stage (Figure 39) is
found at the Ha-erh-pin Aircraft Engine Plant,

The chief difference between Type 1 and Type 2
is in the configurations of the blending and
control buildings. Type 3 differs from Type 2
in having four large underground fuel storage
tanks in addition to the horizontal tanks.
Although the exact function of these sta-
tions is unknown, it is believed that they serve
to blend fuels and control the flow of fuels to
the nearby engine test buildings, to which
they are apparently connected by underground
pipelines.
