Facilities Last updated: January, 2016


  • Several facilities in the DPRK have been linked with the production and/or storage of chemical weapon (CW) agents, their raw chemicals and precursors. CW agents are then moved to either the Sakju(삭주) or Ganggye(강계)-based CW facilities for weaponization. Some of these facilities, including those that produce synthetic fibers (vinalon, also known as Juche Fiber(주체섬유), a polymer that is unique to North Korea), and basic chemicals such as as sulfuric acid and ammonia have been profiled in open sources (including North Korean print media).[1] Some of the active and reserve Nuclear and Chemical Defense battalions are also reportedly based at some of these chemical complexes. However, because photographs of some of these manufacturing sites have been published, and thus their location and other details compromised, one must consider their role in the military production of CW agents as questionable at best.

    Relevant Individuals and Institutions

    As part of a "heavy industry," chemicals are a key component to the command socialist economy in the DPRK, in which all production is under governmental control. With the emphasis of an economy based on military preparedness, it is not an exaggeration to say that all chemical production (as well as other segments of heavy industry) is militarized in the DPRK. It is not clear to what extent to which chemicals are diverted or produced for chemical warfare in North Korea.

    Previously, Kim Jong Il and his military advisors hadcomplete control over policy and procedure for production of armaments. It is expected that his son Kim Jong Un will operate in much the same way. The highest decision-making body in the DPRK for the military industry is the National Defense Commission (NDC). Directly subordinate to the NDC is the Second Economic Committee (SEC), which is the linchpin for much of North Korean development and production of nuclear, biological, and chemical weapons. Created in the 1970s, the SEC is in charge of the planning, manufacturing, and distribution of all ordnance in the DPRK, including international trade in munitions. Located in Kangdong-kun, Pyongyang, the SEC consists of eight bureaus and 190 munitions factories. As of 7 April 2009, Baek Se-bong(백세봉), both NDC and Korean Worker's Party Central Committee member, was appointed director of the SEC. [2] The eight bureaus consist of a general affairs office, with seven others dealing specifically with a variety of weapons platforms and technologies:

    • First Machine Industry Bureau: small arms and ammunition
    • Second Machine Industry Bureau: tanks and armored personnel carriers (APCs)
    • Third Machine Industry Bureau: multi-stage rockets
    • Fourth Machine Industry Bureau: guided missiles
    • Fifth Machine Industry Bureau: nuclear, biological, and chemical weapons
    • Sixth Machine Industry Bureau: battleships and submarines
    • Seventh Machine Industry Bureau: production and purchase of war planes [3]

    With regard to North Korean chemical (CW) and biological (BW) weaponry, the Fifth Machine Industry Bureau is of most relevance. From an organizational perspective, the Ministry of Chemical Industry is actually separate from this line of command, but presumably is in coordination with production and transfer of chemical intermediates for CW agent manufacture.

    Requirements are established by the Second Economic Committee, while the actual production of CW agents is carried out under the directive of the Fifth Machine Industry bureau. The filling, storage, and handling of munitions is carried out under the auspices of the Nuclear and Chemical Defense Bureau (NCDB) (핵 , 화학방위국). Directly subordinate to the General Staff Department (인민군총참부), the NCDB is responsible for defensive and offensive CW operations.

    The Ganggye and Sakju munitions plants represent the meeting of nominally civilian chemical enterprises, under the titles of the Second Economic Committee's General Machine Industry Bureau and the Equipment Department of the NCDB. At Ganggye and Sakju, CW agents brought from the Fifth Machine Industry Bureau are filled into artillery (including mortar and artillery rocket) shells, which are requisitioned from the Third Machine Industry Bureau. Reportedly, chemical spray tanks and aerial munitions are also prepared at Sakju and Ganggye, and can be filled with CW agent from bulk storage at various airfields right before their use in wartime. Also associated with the offensive part of the chemical weapons apparatus, Factory No. 279 is responsible for defensive material, including decontamination chemicals, protective suits, and detection equipment.[4]

    Following their final assembly and filling, chemical munitions are brought to "store offices" at the Maram Materials Corporation and the Jiha-ri Chemical Corporation, located in Maram-dong(마람동), Yonsong-guyok (용성구역), Pyongyang and Jiha-ri(지하리), Pangyo-gun(판교군), Gangwon-do(강원도), respectively.[5] Especially, Maram Materials Corporation was known as facility of three mine facilities and 4 meters tank.[6] Reportedly, North Korean chemical weapons stores are placed into underground tunnels, with bulk CW agents stored in large (12' high) tanks, along with CW defense equipment supplied from Factory No. 279.[7]

    Comprising seven different units, the NCDB is actively involved in the research and development of weapons, as well as nuclear and chemical defense. These are divided into the following departments: operations, training, materials, technology, reconnaissance, section No. 32, and mining/underground facility operations. No. 32 -- an organization of which very little is known--has been linked with research and development of chemical weapons and perhaps specialized warheads for chemical delivery on the Nodong-1. Two additional research institutes -- No. 55 and No. 398 also operate under the aegis of the NCDB. The No. 55 research institute has about 70 on its research staff and is responsible for simulating nuclear and chemical contamination for decontamination operations and training. With approximately 250 researchers, the No. 398 research institute is involved in decontamination operations in both nuclear and chemical environments and is reportedly developing antidotes, masks, and suits.[8]

    According to a 2002 ROK-based article, North Korea operates the following chemical troops: battalion (army corps), battery (division), and platoon (regiment).[9] The NCDB has its own department of operations, consisting of eight battalions. Two of these battalions, the 17th and 18th, are considered active, while the remaining (13th, 14th, 15th, 16th, 27th and 36th) are on reserve. Some of the billets for these battalions have been identified in open literature:

    • 13th NCDB (reserve) Hamhung Vinalon Complex (함흥 비날론 연합 기업소)
    • 14th NCDB (reserve) Sunchon Vinalon Complex (순천 비날론 연합기업소)
    • 15th NCDB (reserve) The plant’s name is unknown
    • 16th NCDB (reserve) Namhung Youth Chemical Complex (남흥 청년 화학 연합 기업소)
    • 17th NCDB (active) Onjong-ri, Songchon-gun, Pyungannam-do (평안남도 성천군 온정리)
    • 18th NCDB (active) Sogam-ri, Pyongwon-gun, Pyongannam-do (평안남도 평원군 석암리)
    • 27th NCDB (reserve) Wonsan, Gangwon-do (North Korean Administrative District, South Korea regards Wonsan as Hamgyongnam-do), The plant’s name is unknown
    • 36th NCDB (reserve) Sariwon Potash Fertilizer Complex (사리원 카리비료 연합 기업소) [10]

    The 18th Nuclear Chemical Defense Battalion consists of six companies. Lee Chung-Guk(이충국), a defector who claims to have served with the 18th Battalion, has diagrammed the locations of Factory No. 279 and the No. 398 Research Institute as below in the "Sogam-ri Recruit Training Center Facilities."

    Lee Chung-Guk has also provided details about the organization of the 18th Nuclear and Chemical Defense Battalion, which may be similar to the 17th and other units held in reserve. According to him, the battalion had a nuclear/chemical reconnaissance company (1st Company), while the 2nd, 3rd, 4th, and 5th companies were described as "decontamination" units. The 6th company was responsible for flame-throwers and presumably obscurant smokes (also referred to as "Smoke Screen Company"). The latter had once been located in Sadong-guyok(사동구역), Pyongyang, and was transferred to the 18th Battalion in June 1993, also according to Lee. Interestingly, none of these companies that were described by Lee had specific duties with regard to offensive use of chemical weapons, but were responsible mainly for reconnaissance and decontamination operations. [12]

    Funding for the Program

    There is no clear evidence or route of funding for DPRK’s CW development. However, regarding DPRK’s current economic situation, most experts presume that cash inflow from abroad is the main source of the funding for development of chemical facilities.  According to Robert Einhorn, the State Department’s special adviser for nonproliferation and arms control, DPRK’s activities for funding is mainly from missile exports, drug smuggling, and currency counterfeiting. [13]

    Financial support from South Korea through Mt. Geumgang tourism development and Kaesong Industry Complex, and aircraft tolls in North Korea’s airspace is also suspected the origin of funding for DPRK’s chemical facilities’ development. [14]

    Past, Present, and Planned Facilities

    The DPRK has operated chemical warfare units since 1954, when it established a program for defensive measures against CW. Seven years later, Pyongyang elevated the department to a bureau, and started to develop chemical weapons. [15]

    Knowledge of North Korea’s current or future plans for CW facilities is limited. In 2003, the U.S. Central Intelligence Agency characterized North Korea as having a “sizeable, but ageing chemical industry,” possibly indicating that economic troubles or a preference for nuclear technology have hampered its ability to modernize its CW program, which by its nature has a short shelf-life. [16] According to South Korean Military, North Korea constructed new biochemical warfare production facility in Chagang-do in December 2010, but the facility’s status, purpose, and size are unknown. [17]

    North Korea’s CW is suspected to export to mid-eastern countries. According to Yomiuri Shinbun on January 5, 2012, chemical ampoule (reagent) related to CW from North Korea to Syria was inspected and confiscated in Greece, and the UN is starting investigation. [18]

    Nonetheless, North Korea has continued to illegally seek out dual-use CW precursors such as sodium cyanide (used for the blood-agent hydrogen cyanide) through its extensive procurement networks. [19]

  • Biological Warfare: Organizations and Dual-Use Infrastructure

    Even less is known about the North Korea biological warfare (BW) program and organization than its chemical warfare (CW) program, on which exists only a paucity of data. Joseph S. Bermudez, Jr. suggests that it follows similar lines as the DPRK CW infrastructure. If this is the case, the Second Economic Committee and its subsidiary Fifth Machine Industry Bureau would fulfill requirements for biological weapons set by the North Korean military. The National Defense Commission and the Ministry of People's Armed Forces direct the latter organizations. One South Korean newspaper account alleged the existence of more than 10 facilities responsible for producing biological weapons; some of these are disguised as electrical engineering concerns. In December 2001, a ROK Ministry of National Defense-produced handbook on weapons of mass destruction (WMD) contained a map showing the locations of suspected BW facilities in North Korea. These included three BW production and six BW research facilities. While the locations of the facilities of the latter group were not carefully identified, the three production sites were located somewhere along the coast (described simply as Sohae, Chongju, and Munchon).

    A few of these facilities have been specifically linked to ongoing work in biological weapons research, development, and manufacture:

    • Research Institute of the Armed Forces Ministry (synonymous with the Bacterium Research Institute, Second Academy of Natural Sciences) is responsible for developing biological weapons.
    • Biological research facility, associated with the North Korean BW program, located in Songch'on County, South P'yongan Province, adjacent to the Onjong-ni chemical weapons facility; growth media is reportedly supplied (200 tons per annum) by a facility in Munch'on, Kangwon Province.
    • 25 Plant/February 25th Plant is a germ-producing facility located in Chongju, North P'yongan Province.
    • National Defense Research Institute and Medical Academy (NDRIMA) perform studies on disease pathogens such as the bacteria and viruses that cause anthrax, cholera, bubonic plague, smallpox, yellow fever, and others.

    Few details are known about these facilities or precisely which microorganisms have been or are being weaponized, if any.

    Reportedly, there exists within the organizational purview of the Nuclear and Chemical Defense Bureau a Chemical and Biological Defense Research Center, in Changsan-dong, Sosong-ku, Pyongyang, with two additional branches in Pyongwon County (South Pyongam Province). It is unknown to what extent this division is responsible for offensive BW work.

    According to defector Choe Ju Hwal, a former sergeant in the North Korean People's Army, there exists a "Joint Research Institute" that is responsible for biological weapons development. This institute is placed within the military-medical department, under the command of the General Rear Service Bureau (GRSB) of the Ministry of People's Armed Forces. The following North Korea facilities have been reported to be conducting BW-related research:

    • (Germ) Research Institute, Second Academy of Natural Sciences
    • Sanitary Quarantine Institute (also known as the National Sanitary and Anti-Epidemic Center)
    • Institute of Microbiology
    • Research Institute of the Armed Forces Ministry
    • First Institute of Bacteriology
    • Second Institute of Bacteriology of Microbiological Diseases, Pyongsong Academy of Science Il-song University
    • Workers Party Central Biology Institute
    • Institute, Academy of Defense Sciences
    • Institute, Academy of Medical Science
    • Military Prevention Medical Unit (also known as the Preventive Military Medical Unit)
    • Munchon, Kangwon Province (agar growth media plant)
    • Defense Research Institute and Medical Academy (NDRIMA)
    • 25 February plant, Chongju, North Pyongan Province
    • Onjong-ni, Songchon County, South Pyongan Province
    • Paekma (rendered Paengma) Section Epidemic Control Center
    • Third Institute of Bacteriology
    • Medical College
    • Military Medical College
    • Institute (Mt. Taesong, P'yongyang)

    Dual-use facilities/organizations

    Various North Korean facilities can be construed as having dual-use purposes that is, could contribute to an infrastructure for the research and development of biological weapons:

    • Institute and Syringe Factory
    • Reagent Company
    • (Synthetic) Pharmaceutical Division of the Hamhung Clinical Medicine Institute Institute (Pyongyang)
    • Pharmaceutical Plant (located approximately 40 kilometers from P'yongyang)
    • Kyong-t'ae Endocrinology Institute
    • Sanitary Quarantine Institute, Ministry of Public Health (germ vaccination institute) also known as the National Sanitary and Anti-Epidemic Center, Moranbong District, P'yongyang

    Other facilities that could be utilized for BW-related work include breweries and other fermentative operations, including breweries that possess significant capacity and potential for production of growth media (e.g., yeast extract). However, no evidence has yet surfaced linking any of these types of facilities with the alleged production of BW agents in North Korea.
