What's Happening?
South Korea's Air Force is participating for the first time in the US Space Force's 'Partner to Win' multinational tabletop exercise. This five-day wargaming event, held in Orlando, Florida, aims to strengthen allied space operations against electronic
warfare threats. South Korea joins the United States, the Netherlands, Sweden, Poland, and Brazil in simulating space warfare scenarios, including satellite jamming and electronic warfare coordination. The exercise is particularly timely as North Korea's GPS jamming operations have seen a significant increase, surging 15-fold from 39 incidents in 2023 to 578 in 2024, according to research from the Brussels School of Governance's Centre for Security, Diplomacy and Strategy. A notable North Korean GPS jamming campaign from May 29 to June 2, 2025, disrupted over 500 aircraft and hundreds of ships in the Korean Peninsula's coastal waters, demonstrating the operational scale of such disruptions. Colonel Kim Si-mon of the ROK Air Force is leading South Korea's delegation, marking a significant step in multilateral space cooperation.
Why It's Important?
South Korea's participation in 'Partner to Win' signifies a critical advancement in its strategy to counter growing electronic warfare threats, particularly from North Korea. The surge in North Korean GPS jamming, attributed to the transfer of Russian electronic warfare technology, poses serious practical consequences for both civilian aviation and maritime navigation, as aircraft lose GPS-dependent approach guidance and ships lose precise positioning. This exercise allows South Korea to enhance interoperability not only with the United States but also with other partner nations, addressing coordination gaps and information-sharing barriers in a simulated environment. For the U.S. and its allies, integrating South Korea, a nation facing one of the most demanding operational threat environments, strengthens the coalition's collective resilience against sophisticated electronic warfare tactics. The insights gained from these wargames are crucial for developing robust responses to real-world GPS disruptions, safeguarding critical infrastructure, and ensuring operational continuity in contested electromagnetic conditions.
What's Next?
South Korea is actively pursuing a layered approach to GPS resilience. In the near term, the country has operationalized the eLoran system, a ground-based navigation technology immune to satellite jamming, providing approximately 20-meter positioning accuracy for key areas. The Korea Augmentation Satellite System (KASS) is also operational, improving GPS accuracy when signals are undisturbed, though it remains vulnerable to jamming. The long-term solution is the Korea Positioning System (KPS), South Korea's independent satellite navigation constellation, projected to be operational by 2035. This system aims to provide GPS-independent positioning, eliminating the current vulnerability. The 11-year development window for KPS highlights the ongoing need for allied coordination and shared space domain awareness, which exercises like 'Partner to Win' aim to foster. Future efforts will likely focus on integrating lessons learned from these exercises into national defense strategies and further developing resilient navigation technologies.
Beyond the Headlines
The dramatic increase in GPS jamming incidents underscores a broader global vulnerability to electronic warfare, extending beyond military conflicts to civilian infrastructure. The reliance of modern society on satellite-derived positioning and timing services for aviation, shipping, logistics, telecommunications, energy, finance, and emergency services means that GPS disruptions can have widespread operational consequences. This situation highlights the urgent need for nations to assess their dependencies on GNSS, identify single points of failure, and develop robust alternative navigation and timing capabilities. The transfer of electronic warfare technology between nations, as seen with Russia and North Korea, also points to an evolving threat landscape where sophisticated jamming capabilities can proliferate rapidly. This necessitates continuous international collaboration, intelligence sharing, and joint exercises to develop effective countermeasures and ensure national resilience in an increasingly contested electromagnetic spectrum.
