Sa-2 Sam Sites Other Missile-Associated Facilities in CHINA, and Unidentified Chinese Missile

Central Intelligence Agency · 2000-06-30 · 21 pages · text by GLM-OCR

This National Photographic Interpretation Center photographic interpretation report, dated January 1965 and released by the Central Intelligence Agency, was prepared for a CIA study of Chinese surface-to-air missile capability. It covers 14 SA-2 SAM sites, 6 former sites, the Tai-yuan Probable Solid Propellants Test Facility and the Peiping Rocket Engine Test Facility. It also estimates hypothetical dimensions of an unidentified Chinese missile from a single Time magazine photograph, cautioning that more photography is needed.

INTRODUCTION

This report has been prepared in response to CIA requirement C-S14-82,085, which requests various data and photographs for support of a study of Chinese surface-to-air missile (SAM) capability.

Information is provided herein on the following missile-associated installations in China (Figure 1): 14 SA-2 SAM sites (including 1 possible site), 6 former SA-2 SAM sites (including 1 possible site), the Tai-yuan Probable Solid Propellants Test Facility, and the Peiping Rocket Engine Test Facility. Table 1 presents data on significant features of the SA-2 SAM sites (Figures 2-20), including the former SA-2s, as observed on successive mission coverages. Table 2 provides information on the rocket engine test facility (Figure 21), and Table 3 provides information on the probable solid propellants test facility (Figure 22).

The mensural analysis of the missile was greatly hampered by the scarcity of photography (only the single photograph was available), the lack of camera data, the cropping of the photograph, and the lack of an object in it of known dimensions for scaling. These factors, particularly the lack of an object for scaling, prevented

the determination of any true dimensions for the missile; however 2 sets of hypothetical dimensions for it have been derived. One set is based on an assumed booster diameter of that of the SA-2 GUIDELINE missile, and the other set is based on an assumed booster diameter of that of the GRIFFON missile (the SA-2 GUIDELINE and the GRIFFON missile resemble the unidentified missile in overall proportions). The accuracy of the dimensions derived for the unidentified missile and shown on the drawing obviously depends upon the validity of the booster diameter which is assumed, but if either diameter is correct the dimensions derived therefrom can be considered accurate to

(whichever is greater). The angle measurements for the unidentified missile can be considered accurate to within The measurements of the SA-2 GUIDELINE and the GRIFFON missile, dimensional drawings of which accompany the sketch of the unidentified missile, have been proven accurate.

The 3 drawings have not been made to scale and are to be used only for dimensional information and as a basis for a rough comparison of the unidentified missile with the SA-2 GUIDE LINE and the GRIFFON. Additional photography and information are needed to obtain more reliable and accurate measurements. The user of this data is advised to apply the measurements herein with extreme caution.

The cutoff date for all information in this report is 1 December 1964.
