This article is part of the "2026 Korea & Global Economy Research" series, the 7th in-depth sectoral analysis following steel, petrochemicals, batteries, shipbuilding, semiconductors, and automobiles. The defense industry is the only manufacturing sector in South Korea to have entered a phase of structural boom, but the nature of that boom — who benefits and what dependencies it deepens — must be analyzed separately.
1. Global Defense Market: Record Defense Spending, Structural Shift
Global military expenditure in 2025 reached a record $2.88 trillion (SIPRI), marking an 11th consecutive year of increase.[1] IISS recorded $2.63 trillion (real +2.5%), and Forecast International projects it will reach $2.6 trillion by the end of 2026.[3]
According to SIPRI data on international arms transfers for 2021–2025, released on March 9, 2026:[2]
- Global arms transfer volume: +9.2% compared to 2016–2020 (largest increase since 2011–2015)
- European arms imports: more than tripled → making Europe the world’s largest importing region (33% of total)
- Arms imports of 29 European NATO countries: +143%. By supplier: United States 58%, South Korea 8.6% (2nd place), Israel 7.7%, France 7.4%
- United States: 42% share of world exports (+27%), exporting to 99 countries
- France 2nd (9.8%), Russia fell to 5th (6.8%, -64%), South Korea ranked around 10th on a five-year cumulative basis (2.2%)
The structural shift revealed by this data: (1) European rearmament has emerged as the central axis of arms demand, (2) while the United States maintains an overwhelming first place, South Korea has rapidly risen to become the 2nd largest supplier to the European market, (3) and the 5th year of attrition in the Russia-Ukraine war, the Iran war, and the Trump administration’s proposed $1.5 trillion defense budget increase for FY2027[3] are structurally supporting demand.
2. Status of South Korean Defense: World's 4th Largest, Explosive Growth on a Single-Year Basis
2.1 Ranking and Market Share
On a single-year basis for 2025, South Korea leaped to become the world’s 4th largest arms exporter. According to the Hankyoreh (2026.4.14), analyzing SIPRI data:[4]
| Rank | Country | Share |
|---|---|---|
| 1 | United States | 42.0% |
| 2 | France | 9.8% |
| 3 | Israel | 7.8% |
| 4 | South Korea | 6.0% |
| 5 | Germany | 5.7% |
The market share increased by 67% in just one year, from 3.6% in 2024 to 6.0% in 2025. On a five-year cumulative basis, South Korea still ranks around 10th (2.2%), but the explosive power on a single-year basis reveals the essence of the defense boom.
2.2 Export Volume
According to the Defense Acquisition Program Administration (DAPA), South Korea’s defense exports in 2025 amounted to approximately 22 trillion won (about $15.4 billion), the largest ever.[5] The Korea Export-Import Bank estimated a maximum of $24 billion (about 35 trillion won) on a contract basis. The core is the 2022 Framework Agreement with Poland. For the four systems — K2 tanks, K9 self-propelled howitzers, FA-50 light attack aircraft, and Chunmoo multiple rocket launchers — the first contract (about 7.6 trillion won) was essentially completed by 2025, and from 2026 the execution phase of the second contract begins.[6] Poland accounted for 46% of South Korea’s major arms exports in 2020–2024.[2]
New contracts with Luxembourg, Saudi Arabia, and other Middle Eastern and European countries continue to be signed in 2026, and the pipeline is rich: the Chunmoo export to Norway, the K9 contract with Romania, discussions on Cheongung-II with Saudi Arabia, etc.
3. Performance of the Big 4 Companies: Combined Q1 Operating Profit of 1 Trillion Won, Order Backlog of 100 Trillion Won
In the first quarter of 2026, the performance of South Korea’s defense 'Big 4' simultaneously set historical highs.
3.1 Hanwha Aerospace
Consolidated revenue of 5.751 trillion won (+5% YoY), operating profit of 638.9 billion won (+20.6% YoY). The ground defense division, boosted by the Chunmoo export to Norway, recorded an order backlog of 39.7 trillion won, the largest ever.[7] The aerospace division also showed growth with revenue of 661.2 billion won. Improved profitability at Hanwha Ocean (shipbuilding division) also contributed to consolidated results.
3.2 Hyundai Rotem
Revenue of 1.4598 trillion won (+23.9% YoY), operating profit of 224.2 billion won (+10.5% YoY), the best Q1 performance ever. With balanced growth in the defense (DS) and railway (RS) divisions, the order backlog approaches 30 trillion won, effectively maintaining 'debt-free management'.[8] Negotiations are ongoing for the second contract of 820 K2 tanks with Poland.
3.3 Korea Aerospace Industries (KAI)
Revenue of 1.0927 trillion won (+56.3% YoY), operating profit of 67.1 billion won (+43.4% YoY). The best quarterly revenue ever.[9] Expansion of FA-50 exports and the domestic military program (KF-21 Boramae system development) simultaneously drove revenue growth. The order backlog is about 25 trillion won.
3.4 LIG Nex1
Revenue of 907.6 billion won (+18.9% YoY), operating profit of 113.6 billion won (+69.6% YoY). Operating margin 12.5%.[10] The export pipeline is rich: Cheongung-II exports to the Middle East (Saudi Arabia, Iraq), Middle East L-SAM, and the U.S. Bigung program. Order backlog about 20 trillion won. In May 2025, the company changed its name from 'LIG Defense & Aerospace' to 'LIG Nex1', integrating its identity around defense and aerospace.
3.5 Combined Big 4
| Item | Q1 2026 | vs. Same Period Previous Year |
|---|---|---|
| Combined Revenue | Approx. 9.3 trillion won | — |
| Combined Operating Profit | Approx. 1.04 trillion won | — |
| Combined Order Backlog | Approx. 115 trillion won | — |
All Big 4 recorded double-digit operating profit growth rates, with especially steep increases at KAI (+43.4%) and LIG Nex1 (+69.6%). An order backlog of 115 trillion won definitively guarantees performance for the next 3–5 years.
4. Structural Growth Drivers: What Supports This Boom
4.1 Normalization of War and European Rearmament
The Russia-Ukraine war (5th year), the Iran war (erupted in 2026), and heightened tensions across the Middle East are structuring arms demand. European NATO countries are resetting their defense spending targets beyond 2% of GDP to 3% or more, and delays in U.S. arms supply (production capacity bottlenecks) are widening the 'niche' for South Korean weapons. SIPRI reported that European arms imports tripled in 2021–2025, a trend not expected to reverse in the short term.
4.2 Price-Delivery Competitiveness
The core competitiveness of South Korean weapons is price-performance ratio plus delivery. The K9 self-propelled howitzer offers equal or superior performance at 50–60% of the price of the German PzH2000, with delivery in 12–18 months, faster than European competitors (24–36 months). The K2 tank, FA-50, and Chunmoo all share this formula. The value of 'immediately available weapons' for countries at war is a competitiveness factor beyond price.
4.3 Reflex Benefit from Saturation of U.S. Defense Production Capacity
U.S. defense companies are at full production capacity due to supporting the wars in Ukraine, Israel, and Iran. Production of 155mm shells, Patriot missiles, and Javelin anti-tank missiles cannot keep up with demand. South Korea is filling this gap. Particularly when European NATO countries seek alternatives to U.S. products, South Korea occupies a unique position as 'an alternative within the U.S. alliance network' .
4.4 Government's All-Round Export Support
The Lee Jae-myung administration has designated defense exports as a national strategic industry and is mobilizing administrative, financial, and diplomatic support. At the '1st Defense Industry Day' in July 2025, President Lee declared that "the defense industry is not only security but also a livelihood," and the ruling party has formalized the goal of K-defense as a top 4 power.[11] After the Lee Jae-myung government took office (June–December 2025), defense contracts with foreign countries amounted to $14.2 billion, exceeding 90% of all contracts for that year. Financial support from the Export-Import Bank and the Korea Trade Insurance Corporation (e.g., providing a $10 billion syndicated loan to Poland) is backing large-scale contracts.
5. 12 Risk Factors — The Reverse Side of the Boom
Looking only at the boom figures, the South Korean defense industry appears to be a 'flawless growth industry.' However, structural risk factors overlap.
5.1 Poland Dependency and Financial Risk
The structure where Poland accounts for 46% of South Korea’s arms exports is a classic case of single-buyer dependence. Poland’s fiscal capacity is not unlimited. To pay for the second contract (820 K2 tanks), Poland relies on large-scale loans from the South Korean government and the Export-Import Bank. The possibility of delayed loan repayments or contract reductions due to political changes (2027 Polish general election) exists.
5.2 Dependency of ROK-U.S. Military-Industrial Linkage
According to the joint fact sheet of the November 2025 ROK-U.S. summit, South Korea confirmed it will purchase $25 billion (about 35 trillion won) worth of U.S. military equipment by 2030.[12] Additionally, it pledged 'comprehensive support' of $33 billion for the U.S. Forces Korea. Defense exports of $24 billion and U.S. arms purchases of $25 billion — these numbers are not symmetrical. South Korea produces weapons under U.S. technology permission and sells them to third countries, then returns a significant portion of those revenues by purchasing finished U.S. weapons. This is closer to a subcontracting hub of the U.S. defense industrial base than an independent defense industry.
5.3 Technology Dependency
The engines of the KF-21 fighter (GE F414), the radar and avionics of the FA-50, the powerpack (transmission and engine) of the K2 tank — a significant portion of core components for South Korea’s main weapons systems depend on U.S. or German technology. Many items require permission from the original technology holder for export approval. The 'self-reliance' of South Korea’s defense industry is limited, which directly creates barriers to exporting to U.S. sanctioned countries like Iran and Iraq.
5.4 Involvement in Conflicts and Loss of Control
When South Korean K9 howitzers are used on the Ukrainian battlefield, FA-50s in Middle Eastern conflicts, and K2 tanks on NATO front lines — South Korea cannot control the end use of these weapons. The SIPRI report also noted "the possibility that weapons systems exported by South Korea could intensify conflicts in various regions." The deeper defense exports go, the more South Korea becomes an indirect party to unintended conflicts.
5.5 Production Capacity Bottleneck
Factory utilization rates at Hanwha Aerospace, Hyundai Rotem, and KAI are already near limits. Producing the first Polish contract took two years, and as the second contract and new exports accumulate, delivery delays and quality issues may arise. Facility expansion takes years.
5.6 Iran End-of-War Scenario
In May 2026, Trump announced that an MOU with Iran was "largely concluded."[13] The end of the Iran war could lead to reduced Middle East tensions → decreased arms demand → contraction of defense stock premiums. In the short term, this is a factor reducing defense demand. However, separate demand axes exist — European rearmament and the Russia-Ukraine war — so the impact will be partially offset.
5.7–5.12 Summary
Other risk factors include: reduced export competitiveness upon won appreciation, possible arms export regulations due to changes in U.S. IRA/tariff policies, political risk from defense corruption/lobbying scandals, labor shortages (shortage of skilled welders and precision machinists), ESG/anti-war sentiment limiting investment (some European pension funds excluding defense investments), and heightened tensions on the Korean Peninsula due to intensified arms race with North Korea.
6. Political Economic Analysis: A Boom for Whom?
6.1 Class Beneficiaries
The direct beneficiaries of the defense boom are clear. Chaebol and mid-sized defense capital — Hanwha, Hyundai Motor Group (parent of Hyundai Rotem), LIG, KAI — monopolize the 115 trillion won order backlog and the 1 trillion won combined Q1 operating profit. Hanwha Aerospace’s 2025 year-end dividend was 7,000 won per share, totaling approximately 360 billion won, an increase of about 100% from the previous year (3,500 won per share, total about 159.1 billion won).[14]
Defense workers (in Changwon, Sacheon, Gumi, Daejeon and other defense-concentrated areas) benefit from job stability and wage increases. Hyundai Rotem’s Changwon factory hired over 500 new workers in 2025. However, this 'benefit' may be temporary, characteristic of a cyclical industry based on war demand, and the opportunity cost of the defense sector boom is borne by society as a whole.
6.2 Opportunity Cost: What Is Being Sacrificed?
An order backlog of 115 trillion won means that South Korea’s manufacturing resources (labor, capital, government support) are being concentrated in defense. In the same period, steel and petrochemicals are in structural crisis, and batteries are mired in deficits due to Chinese oversupply. Concentration of manufacturing resources in defense increases the restructuring costs of other industries.
More fundamentally, the counterpart — $33 billion in support for U.S. Forces Korea plus $25 billion in U.S. weapons purchases — must be paid from the national budget. These are resources that could have been used for welfare, education, housing, and industrial transformation. The fiscal opportunity cost of the defense boom is borne entirely by the working class and ordinary people.
6.3 Military Accumulation of Comprador-Monopoly Capitalism
Seen through the analytical framework of comprador-monopoly capitalism, the South Korean defense industry boom is a classic military manifestation of dual dependency.
- Dependency on the United States: Core technology depends on the U.S., and political approval for large-scale exports is only possible within the U.S. alliance network. The $25 billion purchase of U.S. weapons institutionalizes the structure of 'using money earned from exports to buy American weapons.'
- Export dependence: South Korea’s domestic defense demand (defense budget) alone cannot sustain this industry. More than 60% of production capacity depends on exports, which in turn parasitize on global conflict demand.
- Chaebol concentration: More than 80% of the 115 trillion won defense order backlog is concentrated in two groups: Hanwha and Hyundai Motor Group. The defense boom is a pathway that further solidifies the monopoly position of the chaebol.
The narrative that the defense boom is a 'victory for South Korean manufacturing' is superficially true. But that victory is only possible within the subcontracting structure of U.S. military hegemony; it parasitizes on conflict demand; it strengthens chaebol monopoly. Workers gain jobs in defense factories, but the condition of those jobs is that wars around the world continue.
7. Conclusion: Seeing the Nature of the Boom Clearly
As of 2026, the South Korean defense industry is in a structural boom phase — the only one among manufacturing sectors. Its status as the world’s 4th largest exporter, the Big 4’s combined 115 trillion won order backlog, and the Q1 operating profit exceeding 1 trillion won are undeniable achievements.
But this boom is inscribed with three structural characteristics.
First, it is a war-dependent boom. Global defense spending of $2.88 trillion, European rearmament, Middle Eastern war — if this demand disappears, the growth engine of Korea’s defense industry also disappears. Peace is an economic loss for defense capital.
Second, it is a subcontracting boom under U.S. hegemony. In a structure where technology, political approval, and core components are dependent on the United States, defense exports function as a 'channel for South Korea to be more deeply incorporated into the U.S. alliance network.' The $25 billion purchase of U.S. weapons is the price tag of this dependency.
Third, it is a boom that reinforces chaebol monopoly. The 115 trillion won order backlog is concentrated in a few chaebol like Hanwha and Hyundai Motor Group, while the cost is socialized. The opportunity cost of military expansion (welfare, education, industrial transformation) is borne by the working class.
There is no need to deny the boom itself. The figures and performance are facts. But instead of consuming this boom as a 'national pride' narrative or a 'K-defense myth,' we must face its structural character as the military accumulation of comprador-monopoly capitalism. That is the starting point for the analysis this article proposes.
