Everything You Need to Know: North Korea's Chemical Weapons Are No Joke

North Korea’s chemical-weapons threat is real and the likelihood of their use in wartime is high. Once war is underway, the best way for U.S./South Korean forces to mitigate their effects would be to degrade North Korea’s command and control and take the offensive. If the NK general staff is unable to send orders and receive accurate intelligence, it will find it difficult to plan chemical strikes. A fast-moving UN offensive may also catch slow-moving artillery and missile units.

In recent years, North Korea’s chemical weapons have taken a backseat to her nuclear weapons. They are, however, no less dangerous. The deterioration of the Korean People’s Army (KPA) makes them more essential to victory than ever before. For both practical and doctrinal reasons, North Korea will almost certainly use chemical weapons in wartime, from riot control to lethal nerve gases.

Chemical weapons will be used to create a local, tactical advantage on the front lines and neutralize some advantages, such as air power. Thanks to North Korea’s prodigious missiles and artillery, they can be employed beyond the battlefield as well. North Korea will likely attack South Korea (ROK) through its depth with chemical weapons, from the Demilitarized Zone to Busan.

The vast number of delivery systems would make shutting down the KPA chemical threat impossible during wartime.

North Korean Chemical-Weapons Doctrine

North Korea parses weapons of mass destruction into different usage categories. Nuclear weapons are a strategic deterrent meant to guarantee the security of the Kim dynasty. Northern nukes likely have no operational role in a wartime scenario, since their usage would cause South Korea and the United States to topple the North Korean government.

Chemical weapons, on the other hand, do have an operational role. North Korean military forces train to operate in a chemical environment on a regular basis, and North Korea manufactures its own chemical protective gear and detection systems, some of which have been found bound for Syria.

Chemical weapons would be used in a number of ways, but the primary goal is the suppression of enemy defenses, allowing the KPA to overcome ROK and U.S. forces. Troops fight less effectively when in chemical protective gear, and defenses are dispersed to mitigate the effects of chemical attack.

Given the unpredictability of the battlefield and chemical weapons in particular, North Korean planners will use them as early in the war as possible, when their overall picture of the battlefield is at its maximum. As the war progresses and uncertainty mounts, chemical weapons use will become less productive and even counterproductive.

Types of Chemical Agents

North Korea has a wide spectrum of agents to choose from, and would be expected to tailor its use of chemical agents to the specific task at hand. The effects of these weapons range from temporary incapacitation to death.

The South Korean Ministry of National Defense estimated in 2012 that North Korea had a stockpile of between 2,500 and 5,000 metric tons of chemical weapons. Annual production is estimated at 4,500 tons in peacetime and 12,000 tons in wartime.

North Korea is thought to have chemical weapons from the principle five categories: riot, choking, blood, blister and nerve agents. Riot-control agents are thought to be Adamsite (DM), CN and CS gases. Riot agents and so-called “tear” gases are meant to disperse crowds and are generally nonlethal to healthy adults.

North Korea is also thought to have so-called choking/pulmonary agents, gases that act upon the respiratory system. Short-term exposure requires hospitalization; prolonged exposure is lethal. The KPA is thought to have access to both chlorine-gas and phosgene choking agents.

So-called blood agents, which act through exposure to the human bloodstream, include hydrogen cyanide and cyanogen chloride.

North Korea also has mustard gas, a blister agent, which irritates skin and mucus-production areas, such as the eyes and nose.

Finally, North Korea is believed to have highly lethal nerve agents, which work by disrupting the human body’s nervous system, resulting in asphyxiation. North Korea is believed to have stockpiles of sarin, soman, tabun, VM and VX nerve agents.

According to longtime analyst Joseph Bermudez, North Korea is believed to have specialized in “sulfur mustard, chlorine, phosgene, sarin and the V-agents.”

Delivery Systems

North Korea has a multitude of ways to deliver chemical weapons to targets, ranging from long-range missiles to commandos. Pyongyang will have the ability to attack targets in South Korea and beyond, from locations not just near the DMZ, but theoretically as far as the Russian and Chinese borders.

An important factor to consider in this discussion is the relatively short ranges involved in-theater. The Korean peninsula is relatively short; from Hyesan on the North Korean/Chinese border to the southern tip of South Korea is less than 500 miles, or the distance from Portland, Maine to Baltimore, Maryland. Pyongyang to the DMZ is only 100 hundred miles and only 120 miles to Seoul.
