Other Name: 125호 공장,The 125 Factory, Pyongyang 125 Factory, Pyongyang Pig Factory
Location: Northwestern part of Pyongyang. There are conflicting reports on the location of this facility. Some reports place the factory in Chung'i-dong (중이동), Yongsŏng-kuyŏk (용성구역), Pyongyang, and others place it in Hyŏngjesan-kuyŏk (형제산구역), Pyongyang. Yongsŏng-kuyŏk and Hyŏngjesan-kuyŏk are adjacent to each other, and Chung'i-dong is right next to Hyŏngjesan-kuyŏk, which could be the cause for confusion. The South Korean Ministry of Unification reports that the factory is in "Chunggye-dong" (중계동), Hyŏngjesan-kuyŏk, Pyongyang, but apparently there is no "Chunggye-dong" in Hyŏngjesan-kuyŏk. There is a "Ch'ŏnggye-dong," which is nearby, but in Yongsŏng-kuyŏk.
Subordinate To: Fourth Machine Industry Bureau (제4기계공업국), which is also known as the "Fourth General Bureau" (제4총국) or the "Missile Bureau" (미사일총국), Second Economic Committee (제2경제위원회), National Defense Commission (국방위원회)

According to North Korean defector Ch'oe Ju Hwal, this factory produces missiles, is located in Hyŏngjesan-kuyŏk, Pyongyang, and is nicknamed the "Pyongyang Pig Factory." The press has reported that the No. 125 Factory produces Scud-B and Nodong ballistic missiles, and Silkworm surface-to-ship missiles. South Korean government sources say that visitors from Middle Eastern countries have been to this factory in connection with North Korean "Scud-B" (Hwasŏng-5) sales. [Note: Ch'oe admits in an interview that he has no direct knowledge of North Korean missile production or capabilities, and that others have provided him with missile-related information.]
