ABSTRACT
1. Shen-yang Aircraft Engine Plant 410 is one of the major aircraft engine plants in
Communist China. It is believed to produce the RD-9B turbojet engines for the FARMER
and may also produce sustainer engines for the Chinese surface-to-air missile (CSA-1).
2. The major plant construction at Plant 410 occurred between 1944 and 1962. Since
then, construction has been minor. Plant 410 contained 391,527 square meters (4,214,357
square feet) of floorspace as of July 1972.

INTRODUCTION
engine test buildings had been constructed in the former arsenal area.
5. Other significant installations in the vicinity include Shen-yang Airframe Plant 112
4. Shen-yang Aircraft Engine Plant 410 is located 5 nautical miles (nm) east of the
center of Shen-yang (Mukden), China (Figure 1). By 1956 the original plant, which was
first seen on photography in 1944, 1 had undergone major expansion to include a large
adjacent area which formerly belonged to the Shen-yang Arsenal 90th. By 1962 two aircraft
plants would be more efficient and effective. Shen-yang Rocket Engine Test Facility (BE
5 nm northwest, and the Wen-kuan-tun Ammunition Plant 724
north of Plant 410. The development of Shen-yang Airframe Plant 112,
which produces the FARMER and the sustainer for the CSA-1, corresponds chronologically
with the development of Plant 410. 2 The two installations expanded most rapidly between
1944 and 1956; both appeared basically complete in 1962. It has been Chinese practice to
build engine plants in close proximity to airframe plants so that interface between the
located 13 nm northeast of Plant 410, is an operational static test facility
probably involved in the CSA-1 missile program. This facility may also be associated with
Plant 410.
6. Plant 410 has direct access via roadway to the Shen-yang/Tung-ta Airfield (BE
0.3 nm south of the plant (Figure 1) and to the aircraft repair facilities at the
northeast end of this airfield.
BASIC DESCRIPTION
7. Shen-yang Aircraft Engine Plant 410 encompasses 333 acres and contains 276
structures with a total floorspace of 391,527 square meters (4,214,357 square feet).
8. The original engine plant buildings are located in the eastern section of Plant 410.
These buildings and those subsequently built in this area are separated from the annexed
Shen-yang Arsenal 90th area by a narrow strip of land and a canal (Figures 2 and 3).
However, the two areas are interconnected by a common rail line and paved roads. The
principal buildings identified at Plant 410 include assembly/shops, shops, engine test
buildings, administration and engineering buildings, forges and foundries, warehouses,

Production
9. It is believed that Plant 410 produces the Chinese version of the RD-9B engine. This
afterburning turbojet engine, originally designed by the Soviets, is used in the twin-engine
FARMER (MIG-19). RD-9B engine and afterburner crates have been identified at the
plant. The Chinese version of the FARMER is being produced at the nearby Shen-yang
Airframe Plant 112 which also produces sustainers for the CSA-1. The sustainer engine for
this missile system may be produced at Shen-yang Engine Plant 410. The nearby Shen-
yang Rocket Engine Test Facility has test cells that could accommodate the testing of these
sustainer engines.
Engine Test Buildings
10. Shen-yang Aircraft Engine Plant 410 has three engine test cell buildings
containing a total of 17 test cells (items 24, 130 and 173, Figure 3; Figures 4-7). The largest
of these buildings (item 130) is located in the former Shen-yang Arsenal 90th area and was
first seen in 1962. It (Figure 4) consists of an engine preparation section, a control and
instrumentation section, three double L-type engine test cells, and four single L-type
engine test cells. Eight of the cells were operationally complete in 1962. Each test cell

consists of a raised flat-roofed intake tower, an engine test section, and an exhaust section.
The eight test cells are identical, with the exception of the vertical exhaust ports--four of
which are hinged and four which have opened or grilled apertures. Four probable
observation/control compartments are positioned between the cells to monitor engine test
proceedings. The eight test cells are similar to the engine test cells at Cheng-tu Aircraft
Engine Plant The long exhaust treatment section of each test cell
probably contains a cylindrical duct which acts as a resonator/silencer similar to those at
Cheng-tu.3 The remaining two test cells in the building are similar to the other eight,
except for the exhaust/silencer treatment sections. A cylindrical chamber exits one test cell
and divides into two parallel silencers/diffusers with vertical exhaust ports. The other test
cell consists of a single cylindrical silencer/diffuser. It expands from to
in the exhaust/silencer chamber. This cell also has vertical exhaust
port. The exhaust/silencer chambers of two test cells were added in 1966 and 1967.
11. An engine test cell building (item 24, Figure 3; Figure 6) was present in the original
plant area in 1944. The rectangular building consists of two U-type engine test cells and
four through-type engine test cells. One of the through-type engine test cells was modified in
1963 by the addition of a walled concrete exhaust apron used to prevent ground erosion
from engine efflux.
12. The third engine test facility consists of three buildings (items 171--173, Figure 3;
Figure 7). A former diesel powerplant (item 171, Figure 7) had been converted between 1956
and 1962 into a probable compressor/test building. This building now appears to be
inactive and in a state of disrepair. Sections of the exhaust system have been either
dismantled or are deteriorating. Another probable test building (item 173, Figure 7)
consists of a control room and an L-type test cell. This building also appears to be inactive
and partially dismantled. The test cell building is connected to a probable control/engine
test preparation building (item 172, Figure 7) by a large conduit. It is doubtful that any of
the three buildings which constitute this facility are now being used in the plant's engine
test program.
Chronology
13. When Plant 410 was first seen on photography in 1944, the original plant area
contained 66,520 square meters (716,014 square feet) of floorspace. Buildings complete at
that time included an engine test cell building (item 24) an assembly/shop building (item
30), two forges (items 4 and 12), and eight shop buildings (items 3, 5, 7, 16, 21, 28, 29, and
38). Shen-yang Arsenal 90th area then contained 80,092 square meters (862,102 square feet)
of floorspace. Buildings at the arsenal area at that time included four foundries, 11 shop
buildings, and several warehouses.
14. By 1956, the Shen-yang Arsenal 90th area had been annexed by Plant 410. It was
also evident that several major buildings had been completed in both of these areas. These
included five major assembly/shop buildings (items 55, 61, and 114--116) and a fuel storage
facility (item 23). The total floorspace for Plant 410 as of 1956 was 291,030 square meters
(3,132,617 square feet). The construction program in both plant areas from 1945 through
1956 had nearly doubled the total floorspace available.
15. A high-level of construction activity continued from 1957 through 1962. The major
additions included an engine test cell building (item 130) and the conversion of a
powerplant to a probable compressor/test building (item 171, Figure 3; Figure 7). The total
floorspace of the plant by August 1962 was 381,930 square meters (4,111,056 square feet).
Modifications were made on the engine test cell building (item 130) with the addition of
silencers/diffusers on two test cells (item 130c); one cell was modified in 1966 and the other
in 1967. However, since 1963 construction activities observed at the plant other than the
test cell addition have been minor. These have consisted primarily of support-type
structures.
Essential Services
16. Shen-yang Airframe Plant 410 is served by both road and rail. A network of good
roads interconnects the plant facilities, and a paved road extends from the plant to the city
center of Shen-yang. A railroad spur which extends from the main rail system serving Shen-

yang enters the plant from the west and terminates at the east end of the plant. Within the
plant, several tracks extend from the spur to serve the two fuel storage facilities,
warehouses, and an assembly/shop building.
17. Shen-yang/Tung Ta Airfield has facilities to sup ort the logistical needs of Plant
410. This airfield has a concrete runway with a 25X1
concrete parallel taxiway and five concrete parking aprons.
18. Electrical power is available to the Shen-yang area from the resources of a large
hydroelectric powerplant and a large thermal powerplant complex near Fu-shun,
approximately 23 nm east of Plant 410. Plant 410 has its own substation and several small
heating plants to support its heating requirements.
Security
19. Both plant areas are separately secured by walls. Guard posts or control buildings
monitor each access point. In the original aircraft engine production area, guard towers are
located at various points near or along the wall. Defensive personnel trenches are also
located inside the eastern wall of this area. No other special security measures were noted
throughout the plant areas.
