Last Updated: April 1, 2003
Other Name: 만경대보석가공공장, No. 1329 Factory, Jewel Processing Factory, Factory No. 1329
Location: About 2.5km northeast of Changhun 2 Dong (장훈2동), Man'gyŏngdae-kuyŏk (만경대구역), Pyongyang (평양시), North Korea
Subordinate To: Third Machine Industry Bureau (제3기계공업국), which is also known as the "Third General Bureau" (제3총국) and as the "Electronic Automation Bureau" (전자자동화총국), Second Economic Committee (제2경제위원회), National Defense Commission (국방위원회)
Size: According to North Korean defector Kim Myŏng Ch'ŏl, there were plans to move the facility to an underground location by 1999. The new location is about 2.5km northeast of the previous facility in Changhun 2 Dong , Man'gyŏngdae-kuyŏk, Pyongyang.
Facility Status:

According to North Korean defector Kim Myŏng Ch'ŏl, the Man'gyŏngdae Jewel Processing Factory was located above ground in Changhun 2 Dong, Man'gyŏngdae-kuyŏk, Pyongyang until the time of his defection in 1993. However, Kim says there were plans to move all facilities to an underground location by 1999. All items produced at this factory are shipped as components to other weapons plants, including missile factories. As of January 1993, the factory was divided into eight work sections or workshops (職場):

  • Workshop 1-Assembly (組立)
  • Workshop 2-Optics (光學)
  • Workshop 3-Processing (加工)
  • Workshop 4-Hydrogen (水素)
  • Workshop 5-Electronics (電子)
  • Workshop 6-Casting (鑄物)
  • Workshop 7-"Transcription" or "Copying and Etching" (轉寫)
  • Workshop 8-Shipping and Receiving (運輸)

The factory has three shifts and operates 24 hours a day. In 1993, the factory was managed by Shin T'ae Gyun (신태균). Kim Myŏng Ch'ŏl says he traveled to the Russian far east three times to procure integrated circuits (ICs) for use in the factory. The factory also obtained Japanese ICs from the pro-North Korean General Federation of Korean Residents in Japan (Choch'ongnyŏn). Kim knows this information from looking at packing lists and invoices; however, he does not know how the orders were sent to Japan. Kim says the ICs he obtained in Russia were used in the production of rockets, tanks, and submarines, but that this information was not revealed to the Russian supplier. Kim says National Defense Commission Chairman Kim Jong Il became very interested in precision-guided munitions after the Gulf War, and that Kim Jong Il allocated $500,000 in foreign exchange to develop laser-guided weapons. Kim Myŏng Ch'ŏl also visited the shipping departments of the "Pyongyang Pig Factory" (No. 125 Factory) and the "T'aep'yŏngyang Rocket Factory," which received components from the Man'gyŏngdae Jewel Processing Factory. Kim also claims that this plant manufactures a secret so called "No. 5 weapon," but he does not know what the weapon is.
