Analyzing the Growth of South Korea's Drone Industry and the Structuring of Inter-Korean Unmanned Military Power Competition

Executive Summary

The codification of unmanned and electronic warfare elements in the ROK-U.S. Ulchi Freedom Shield (UFS) exercise is emerging as a variable that destabilizes the premise of North Korea's deterrence structure, which has relied on nuclear weapons and missiles to offset its conventional inferiority. Defining these elements not as a bilateral inter-Korean issue but as an implementation measure for integration into the U.S.-ROK-Japan collective defense system, North Korea has responded by dual-tracking its statements toward South Korea and Japan. Meanwhile, Kim Jong Un ordered the expansion of AI- and automation-based production capacity during his inspections of munitions factories. South Korea is seeking to build up both defensive and offensive capabilities by unveiling Hanwha's unmanned ground vehicle (UGV) and concurrently pursuing the K2 active protection system (APS) project, a move closely linked with industrial policy calculations to secure defense export competitiveness. Among the potential future paths—managed competition where statement escalation remains at a verbal level, the normalization of low-intensity competition, or the expansion of physical provocations—the normalization of low-intensity competition is the most likely (50% probability). Accordingly, the Ministry of National Defense needs a dual-track response that maintains the force integration schedule while adjusting the level of disclosure for training information. Furthermore, U.S. regulatory and tariff moves regarding foreign-made unmanned systems could act as a constraint on South Korea's defense export strategy, requiring a separate review of countermeasures.

I. Issue Analysis

Analyzing the Growth of South Korea's Drone Industry and the Structuring of Inter-Korean Unmanned Military Power Competition: Issue Analysis

1. Background and Progress of the Issue

In early September, a joint demonstration by the ROK and U.S. Marine Corps was conducted near Seoul. The demonstration featured low-cost drones priced at around $2,000 per unit [3]. This is an instance where unmanned systems have officially emerged as a variable in the 76-year-old inter-Korean military standoff [3].

This demonstration was an extension of the Ulchi Freedom Shield (UFS) exercise held from August 17 to 21 [3]. The ROK and U.S. military authorities had announced in advance during the preparation phase of UFS that they would incorporate lessons learned from the war in Ukraine [3]. This included training elements assuming an advanced operational environment, such as unmanned warfare, electronic warfare, and cyber warfare [3].

A spokesperson for North Korea's Ministry of Foreign Affairs pointed this out precisely in a statement on August 14. The statement specified that "various practical drills simulating an advanced operational environment, such as field maneuver exercises including Warrior Shield, unmanned warfare, electronic warfare, and cyber warfare, are scheduled to be pushed forward" [3]. What North Korea took issue with was not whether the exercises were being held regularly, but rather the qualitative change in the scenario content—namely, the expansion of advanced operational elements itself [3].

North Korea's backlash has escalated in stages. On August 6, a military commentator for the Korean Central News Agency (KCNA) defined U.S.-Japan-ROK cooperation as a "'tripartite' threat that has solidified into a new security crisis" [3]. This was followed by the launch of short-range ballistic missiles on August 12 [3]. North Korea interprets South Korea's advanced operational elements, such as unmanned aerial vehicles (UAVs) and electronic warfare, as implementation measures for integration into the U.S.-led "collective defense" system. The KCNA pointed out that the United States deployed an MQ-9 Reaper drone unit to South Korea and reinforced the deployment of F-16 fighter jets [18]. Moves to deploy multi-domain rapid maneuver forces are also mentioned in the same context [18].

2. Current Situation

The expansion of unmanned military capabilities by South Korean defense companies is extending beyond training ground demonstrations to ground equipment systems. Hanwha unveiled its next-generation unmanned ground vehicle (UGV) at its Changwon facility. A low-profile infantry support vehicle designed for supply missions was demonstrated navigating rough terrain on six airless tires [1]. This trend, running parallel to the K2 tank active protection system (APS) project, is understood as a move to expand response capabilities in both defensive and offensive dimensions [3].

North Korea's response is also being carried out in parallel through official statements. On September 21 and 22, the KCNA and the Rodong Sinmun criticized Japan's "new combat methods" strategy utilizing UAVs and AI, as well as its revision of the Three Principles on Transfer of Defense Equipment and Technology, defining them as the expansion of a "war industry" [12][15]. This can be seen as an extension of a dual-track strategy that runs statements targeting Japan in parallel with, but separate from, those targeting South Korea. Meanwhile, during a three-day inspection of major munitions factories in the third week of September, Kim Jong Un ordered the expansion of production capacity and the modernization of weapon systems based on AI and automation. The inspections are analyzed to have included production lines related to 600mm super-large multiple rocket launchers [14].

The competition over unmanned military capabilities is also expanding globally. The U.S. Central Command is evaluated as functioning as a "battle lab" for the real-world validation of unmanned systems [4]. The U.S. Navy established the Robotics and Autonomous Systems Warfare Development Center at Joint Expeditionary Base Little Creek in Virginia [11]. China has secured economies of scale, with the number of registered drones surpassing 3.28 million, while U.S. import restrictions are having the counterproductive effect of encouraging detour exports through third-party markets [9]. Although this U.S.-China competition is a separate axis from the unmanned military competition on the Korean Peninsula, it influences South Korea's options in terms of supply chains and technical standards.

3. Key Actors and Positions

South Korean Ministry of National Defense and defense industry: Defense companies, led by Hanwha, are positioning the integration of AI-based UAVs and UGVs as a core pillar of ground warfare innovation [1]. Concurrently pursuing the K2 tank active protection system and low-cost drone integration is an approach aimed at expanding both defensive and offensive capabilities simultaneously [3]. The potential for exporting low-cost anti-drone solutions is also being examined [6].

ROK-U.S. Combined Forces Command and U.S. Forces Korea: They are pushing to regularize advanced operational scenarios, including unmanned warfare, electronic warfare, and cyber warfare, through the UFS exercise [3]. While this is explained as reflecting lessons learned from the war in Ukraine, North Korea perceives it as a qualitative escalation of the threat rather than a mere expansion of the exercise scale [3].

North Korean Ministry of Foreign Affairs and the Korean Central News Agency: They maintain a dual-track statement strategy targeting the United States and South Korea separately. Through channels targeting South Korea, they define UFS and unmanned warfare elements as a "tripartite threat" [3], while through channels targeting the United States, they interpret them as an attempt to integrate South Korea into a "collective defense" system [18]. Concurrently, through channels targeting Japan, they separately criticize Japan's revision of the Three Principles on Transfer of Defense Equipment and Technology and its expansion of drone production as the expansion of a "war industry" [12][15].

Kim Jong Un and the Second Economic Committee: They are responding beyond the level of statements by expanding physical production capacity. Kim Jong Un directly ordered the modernization of weapon systems based on AI and automation during his inspections of munitions factories [14]. This suggests that substantive military buildup is being carried out in parallel, independent of adjustments to the tone of their statements.

United States (BIS and Department of Defense): The United States is conducting a national security investigation into imports of unmanned aircraft systems [2], a measure unfolding as part of the U.S.-China technological hegemony competition rather than being specific to the Korean Peninsula [9].

4. Key Issues

The first issue is the substance of the "qualitative threat" frame emphasized by North Korea in its statements. North Korea is taking issue not with the scale of the exercises, but with the advancement of the scenario content itself, such as unmanned and electronic warfare [3]. This suggests that North Korea's statement tone is likely to escalate in tandem whenever South Korea expands its unmanned military capabilities in the future.

The second issue is whether there is a gap between North Korea's statements and its actual responses. While North Korea employs different rhetoric by separating its channels toward South Korea, the United States, and Japan [3][18][12], it is actually expanding munitions factory production capacity and introducing AI and automation in parallel [14]. The fact that political narratives and the reinforcement of military capabilities proceed on separate tracks is an aspect that South Korea must equally consider in its response.

The third issue is the speed of escalation in the low-cost drone competition. The demonstration of low-cost drones priced at around $2,000 per unit [1][3] can be described as the Korean Peninsula's version of the global trend toward low-cost, attritional unmanned systems that has spread since the war in Ukraine. The case of Poland, where the budget for drones and anti-drone systems surged from approximately $27 million at the end of 2023 to about $6.9 billion this year [17], demonstrates that once a low-cost unmanned military competition begins, the budget scale can expand non-linearly. It is difficult to rule out the possibility of a similar trajectory repeating between North and South Korea.

II. In-Depth Analysis of the Issue

Analyzing the Growth of South Korea's Drone Industry and the Structuring of Inter-Korean Unmanned Military Power Competition: In-Depth Analysis

1. Root Cause Analysis

The trigger for this competitive dynamic is not technology itself, but rather the empirical data provided by the war in Ukraine, where low-cost drones were repeatedly seen neutralizing expensive armored forces. This experience was directly reflected in the training scenario designs of the ROK and U.S. military authorities [3]. This is the background behind the codification of unmanned warfare, electronic warfare, and cyber warfare as elements of an advanced operational environment in the UFS exercise [3].

North Korea's logic of response is of a different nature. North Korea does not take issue with the scale of the exercises or their repetitive execution; rather, it defines the qualitative expansion of the scenarios itself as a threat [3]. This is closely linked to Pyongyang's assessment that the premise of its deterrence structure—wherein it has offset its conventional inferiority with nuclear weapons and missiles—is being shaken. When unmanned warfare is combined with electronic warfare, the possibility of precision strikes against early warning and command-and-control nodes increases. From the perspective of the North Korean leadership, this directly translates into a threat to the survivability of its nuclear command-and-control system.

South Korea's underlying drivers are twofold. One is the demand to replace manned forces due to a shrinking pool of military personnel. Although the low-profile UGV unveiled by Hanwha in Changwon started with the simple mission of supply transport, it is read as the starting point for transitioning to a manpower-saving force structure [1]. The other is securing competitiveness in defense exports. Concurrently pursuing the K2 tank active protection system and low-cost drone integration is closely linked to industrial policy calculations aimed at leveraging domestic force integration track records into overseas contracts [3].

2. Structural Context

Security Structure

The competition over unmanned military capabilities on the Korean Peninsula cannot be separated from the broader trend of technological rearmament across Northeast Asia. Since the inauguration of the Takaichi administration, Japan has formalized UAVs and AI as the core of its "new combat methods" [12][15]. The revision of the implementation guidelines for the Three Principles on Transfer of Defense Equipment and Technology to ease weapon export restrictions follows the same trend [12]. North Korea defines this as an opportunity for the rearmament of "war criminal enterprises" such as Mitsubishi Heavy Industries and Kawasaki Heavy Industries, issuing statements targeting Japan in parallel with those targeting South Korea [15]. North Korea's KCNA criticized that "when the Minister of Defense took the lead in talking about producing and possessing offensive drones domestically, military monopolies colluding with neo-militarist forces swarmed like blowflies to develop drones" [15].

Separately, North Korea points to the ROK-U.S. alliance itself as the institutional framework for the deployment of unmanned military capabilities. The KCNA interpreted that "while reducing its stationing forces in other regions including Europe, the United States deployed the strategic-purpose 'MQ-9' (Reaper) drone unit to South Korea, reinforced the deployment of 'F-16' fighter jets, and is even attempting to deploy multi-domain rapid maneuver forces" as an attempt to integrate South Korea into a "collective defense" system [18]. The expansion of participation in multinational exercises such as UFS, RIMPAC, and Pacific Vanguard is also defined as measures to "enhance the joint operation system and integrated operation execution capabilities" [18]. This demonstrates that North Korea treats the issue of unmanned military capabilities not as a bilateral inter-Korean dynamic, but as a sub-variable of the expansion of the U.S.-ROK-Japan collective defense system.

Industrial and Economic Structure

The competition over unmanned military capabilities is intertwined with the reorganization of the defense supply chain. The United States imposed regulations and tariffs on foreign-made robots and drones in July and August 2026 [9]. However, China has already secured economies of scale, with registered drones exceeding 3.28 million [9]. Some evaluate that the U.S. blockade of individual markets is producing the paradoxical result of encouraging Chinese companies to export through third-party markets [9]. In this phase of supply chain reorganization, South Korean defense companies may find opportunities in supplying intermediate goods and preempting standardization rather than competing in finished products [9]. Hanwha's attempt to export low-cost laser weapons to NATO members in Eastern Europe suggests a path for middle-power defense companies to enter markets based on real-world demand, independent of the U.S.-China bipolar structure [6].

Political Structure

North Korea's dual-track statements targeting the United States and South Korea are not accidental rhetoric but a strategy to manage negotiating leverage. A disciplined pattern is observed where Pyongyang elevates the UAV and electronic warfare threat to a "structural threat" but does not immediately translate this into military countermeasures [3]. This aligns with the analysis that North Korea is diversifying its coercive leverage in the information age by expanding its cyber and space capabilities [8]. Unlike the Kim Il Sung system, the Kim Jong Un regime is evaluated as actively utilizing internet and cyber capabilities as a means of deterrence [8], and statements regarding unmanned military capabilities also serve as a pillar of this asymmetric deterrence diversification.

3. Historical Precedents and Comparative Case Analysis

The closest precedent is Iran's experience in operating low-cost drone capabilities. As Iranian-made disposable attack drones and their derivatives have been repeatedly used in Middle East conflicts, it has been empirically proven that low-cost drones can reverse the cost-efficiency of expensive air defense and armored systems [17]. This experience has been directly reflected in the responses of European nations. Poland increased its budget for drone and anti-drone systems from approximately $27 million at the end of 2023 to about $6.9 billion this year, and established domestic drone factories [17]. Six countries, including France, Germany, and the United Kingdom, signed a letter of intent to jointly develop disposable attack drones with a range of over 300 miles and a target unit cost of less than $100,000 [17]. This demonstrates that the inter-Korean unmanned military competition is not an exceptional phenomenon, but rather the Korean Peninsula's version of a global pattern where low-cost asymmetric capabilities are reshaping the traditional calculus of the balance of power.

The case of the Taiwan Strait also serves as a valid comparative reference. The PLA unveiled a laser-equipped amphibious armored vehicle designed for Taiwan landing operations, which, coupled with Taiwan's attempts to expand its own drone capabilities, has formed an asymmetric drone versus anti-drone competitive dynamic [6]. Taiwan's largest aerospace and defense company, AIDC, raised the necessity of low-cost anti-drone defense systems, citing China's accelerated drone development [6]. However, there are assessments that even within the PLA, the offensive use of combat AI remains in the exploratory phase due to political caution [6]. This suggests that competition over unmanned military capabilities does not immediately translate into operational superiority through technology acquisition alone, a lesson that could similarly apply to the inter-Korean dynamic.

It is also necessary to point out the differences from the conventional arms race of the Cold War era. In the past, the inter-Korean arms race centered on competing over the quantity of platforms, such as tanks and artillery. The current competition over unmanned military capabilities is different in nature, as command-and-control and information-fusion capabilities, rather than platforms, determine victory or defeat. This is supported by the U.S. Navy's establishment of the Robotics and Autonomous Systems Warfare Development Center, which made personnel training itself a separate organizational task [11]. Given that the competition to acquire unmanned systems directly leads to competition over transitioning troop employment doctrines and training systems, both North and South Korea face organizational challenges that go beyond merely acquiring hardware.

4. Key Variables Shaping Future Developments

The first variable is whether North Korea links its statements with actions. To date, North Korea has escalated its statements and conducted short-range ballistic missile test-launches in parallel, but has refrained from direct military responses regarding unmanned capabilities themselves [3]. Whether this line of restraint is maintained will determine the continuation of the path toward the normalization of low-intensity competition.

The second variable is the speed at which Kim Jong Un's munitions factory inspections translate into actual increases in production capacity. During a three-day tour of munitions factories under the Second Economic Committee in the third week of September, Kim ordered the modernization of weapon systems based on AI and automation [14]. The nature of the competition will depend on whether this materializes into the expansion of capabilities to counter UAVs and electronic warfare, or remains limited to upgrading existing missile and multiple rocket launcher production lines.

The third variable is the scale of the windfall benefits that U.S. regulations on Chinese robots and drones bring to the South Korean defense industry. While U.S. import restrictions prompt Chinese companies to detour through third-party markets [9], they can simultaneously provide South Korean companies with opportunities to supply intermediate goods and preempt standardization. The speed at which these opportunities are converted into actual contracts will determine the financial sustainability of the domestic defense industry.

The fourth variable is the execution speed of Japan's revision of the Three Principles on Transfer of Defense Equipment and Technology and the intensity of North Korea's statements targeting Japan. As long as North Korea maintains its dual-track statements targeting South Korea and Japan, this is likely to produce the counterproductive effect of actually strengthening the cohesion of U.S.-ROK-Japan security cooperation [12][15][18].
