South Korea Sets Sights on Becoming the World’s Fourth-Largest Defense Power by 2030

South Korea opened its largest-ever Seoul International Aerospace & Defense Exhibition on Monday with a clear ambition: to vault into the world’s top four defense powers by 2030.

President Lee Jae-myung pledged a larger-than-expected surge in research and development for defense and aerospace over the next five years, framing “technology sovereignty” in critical inputs—such as specialized semiconductors—as central to the plan.

The push builds on rapid momentum. South Korea has climbed into the global top tier of arms exporters, with sales accelerating since Russia’s invasion of Ukraine triggered a European rearmament cycle.

At this year’s ADEX, more than 600 companies from 35 countries are showcasing unmanned and AI-enabled systems—from loitering munitions and automated howitzers to the KF-21 fighter—signaling where Seoul expects the market to grow fastest.

Exports are the engine. Seoul’s signature packages combine quick delivery with co-production and technology transfer, aiming to help buyers expand their own defense bases while locking in long-term Korean supply chains.

Poland has become the marquee customer for this model, with a multi-year program spanning tanks, howitzers, rocket artillery and light fighters—an approach South Korea now wants to replicate with partners in Europe, the Middle East and Asia.

Money will follow the rhetoric. The government has flagged a sharp increase in defense outlays for 2026, creating fiscal room to scale production and meet export backlogs while funding the next wave of R&D.

The agenda reaches beyond hardware: Lee’s team is pitching the transfer of manufacturing know-how, tooling and training as part of the export offer, which could deepen industrial ties well past initial contracts.

Why it matters—especially for readers in Brazil and Latin America: South Korea’s ascent widens the field of major suppliers just as many countries modernize their forces and seek reliable alternatives with shorter delivery times.

The emphasis on AI, autonomy and electronics dovetails with civilian industries, promising spillovers in chips, avionics and advanced manufacturing.

For governments and firms weighing partnerships, Seoul’s co-production model—rather than simple off-the-shelf sales—offers a path to build local capacity while accessing a fast-moving supply chain.
