Despite the Republic of Korea’s (ROK/ South Korea) defense budget shrinking in 2024 and 2025, 2026 recorded a 9.7% jump in spending. Defense spending in the ROK has fluctuated in line with North Korean defense posture since the Korean War. Nuclear developments over the past year, such as accelerating development of ballistic missiles and submarine capabilities, have forced Seoul to aggressively fund its preemptive strike framework. Additionally, over the past decade, the country has undergone a shift towards fostering domestic manufacturing capability, only procuring internationally as part of a political or economic deal with the given country, like with the US submarine deal, for instance. The country’s desire to foster its defense industrial base, combined with both a volatile US-China trade war and burden-sharing pressures from Washington is forcing South Korea to increase its defense spending substantially over the next ten years. During the period 2022-26, the ROK’s total defense budget recorded a CAGR of 2.8%, rising from $42.3 billionin 2022 to $47.2 billion in 2026.

Personnel remains the largest expenditure for the ROK’s Ministry of National Defense (MoND), accounting for 39% of all defense spend in 2026. While personnel is forecasted to grow at a CAGR of 3.6% over the period 2027-31, South Korea’s world-lowest fertility rate has reduced the amount of eligible conscripts, with the number of 20-year-old males in the country dropping 30% between 2019 and 2025. Because of these demographic issues, South Korean military leadership has indicated a shift towards AI and robot-enabled warfare. Defense Innovation 4.0, South Korea’s defense reform strategy, is pivoting the country’s military towards manned-unmanned teaming (MUM-T) and AI-enabled command networks, as well as procuring platforms like smart battleships and jets. RDT&E, therefore, has the highest CAGR between 2027 and 2031, going from $4.2 billion in 2026 to $6.0 billion in 2031. South Korea is allocating 30% of its total defense budget to RDT&E and acquisition for 2026, increasing to 32% come 2031. Overall, the South Korean defense market is set to grow at a CAGR of 3.9% between 2027 and 2031, increasing from $48.4 billion in 2027 to $56.3 billion in 2031.
