According to U.S. and South Korean government sources, the Pyongyang Semiconductor Factory produces electronic components for missiles. The Pyongyang Semiconductor Factory was completed in April 1987 as a prototype production plant with assistance from the United Nations Development Program. In 1989, the facility was expanded into a regular production plant. Analysts have speculated that semiconductors and other components produced at this facility have been used in the production of missiles. Although this is almost certainly correct, North Korea is not self-sufficient in semiconductor production, and Pyongyang’s technological capabilities in this area are relatively backward. According to defector Kim Myŏng Ch’ŏl, North Korea was procuring integrated circuits from the former Soviet Union, later Russia, and Japan to be used in rockets, tanks, and submarines while he worked at the Man’gyŏngdae Jewel Processing Factory from 1986 to 1993. [Note: The pro-North Korean General Federation of Korean Residents in Japan (Choch’ongnyŏn) has provided assistance for other computer and information technology facilities, and could have provided assistance for this facility as well.]
