South Korea Plans Defense Budget Boost to Become World's 4th-Largest Arms Producer by 2030

South Korean President Lee Jae Myung announced at the Seoul International Aerospace & Defense Exhibition (ADEX) 2025 that South Korea will allocate a "larger-than-expected budget" for defense and aerospace research through 2030, aiming to become the world's fourth-largest defense industry. Currently ranked 10th in global arms sales, the country plans to achieve technological sovereignty by investing in the independent development of critical technologies such as specialized semiconductors. South Korea's defense exports have surged, particularly in the wake of Russia's invasion of Ukraine, with multibillion-dollar deals involving howitzers, missiles, warships, and AI-enhanced unmanned weapons. President Lee emphasized sharing not only weapons systems but also industrial expertise with overseas partners, reflecting the country's commitment to building a robust defense ecosystem. This push positions South Korea as a rising competitor in the global arms market, challenging traditional defense powers by leveraging its advanced technology and manufacturing capabilities. The government's strategic focus on indigenous innovation aims to reduce reliance on foreign suppliers and strengthen South Korea's defense industry foundation.
