Suwon Airport — Suwon, South Korea

Suwon Airport (SWU) is a joint civil-military airfield located south of Seoul in Gyeonggi Province, South Korea, primarily operated as a Republic of Korea Air Force base while also accommodating limited domestic civilian flights. The base hosts fighter squadrons and plays a role in South Korea's national air defense posture, given its proximity to Seoul and the broader Korean Peninsula's security concerns. Civilian operations at SWU have historically included short domestic routes, though passenger traffic remains modest compared to major South Korean airports like Incheon or Gimpo. The dual-use nature of Suwon Airport reflects a common arrangement in South Korea, where military necessity and civilian aviation needs share limited airfield infrastructure near the densely populated capital region.
