Freedom Edge
Overview
Freedom Edge is a multi-domain joint military exercise involving South Korea, the United States, and Japan. It was designed to go beyond the existing bilateral ROK-US, US-Japan, and ROK-Japan exercises and, for the first time, have the three countries demonstrate combined operational capabilities across all warfighting domains, including maritime, air, ground, and cyberspace. It was first conducted in June 2024, and is intended to respond to North Korea's nuclear and missile threats and to guarantee freedom of navigation and stability in the Indo-Pacific region.

Exercise Background
North Korea's continued ballistic missile launches and the operation of underground nuclear test facilities have heightened tensions in the security situation on the Korean Peninsula and in East Asia. In response, South Korea, the United States, and Japan agreed to institutionalize security cooperation at a summit held at Camp David in August 2023. The Freedom Edge exercise was pursued as an extension of that agreement. The ROK and the United States had already conducted large-scale combined exercises such as Freedom Shield and Key Resolve, and the United States and Japan had carried out exercises such as Orient Shield, but trilateral cooperation within a single exercise framework was also groundbreaking in military history.
The First Exercise (2024)
The first Freedom Edge exercise was held from June 27 to 29, 2024, in international waters southeast of Jeju Island and in adjacent airspace. The navies and coast guards of South Korea, the United States, and Japan took part, with seven surface ships including the aircraft carrier USS Theodore Roosevelt (CVN-71), as well as destroyers, frigates, submarines, patrol aircraft, and fighter jets. On the South Korean side, the Aegis destroyers ROKS Sejong the Great and ROKS Usangyeong participated, and on the Japanese side, the Aegis destroyer JS Taikai participated. The exercise included anti-submarine warfare, air defense, maritime interdiction operations, and procedures for responding to threats in cyberspace. In particular, the three nations' warships forming a single task group to conduct tactics was assessed as having elevated the previous approach to a new level.
Significance and Reactions
The Freedom Edge exercise is significant in that it shows that ROK-US-Japan security cooperation is not merely a declaration but has been realized as actual military capability. South Korea's Joint Chiefs of Staff stated that the exercise was planned to respond to North Korea's nuclear and missile threats and illegal maritime fishing. The United States emphasized the synergy of the alliance system that serves as the linchpin of its Indo-Pacific strategy. Japan's Ministry of Defense explained that the exercise would improve interoperability among the three countries and allow the natural exploration of the possibility of exercising collective self-defense. During the exercise, North Korea launched short-range ballistic missiles into the East Sea on June 27 in protest. In response, the South Korean government warned against distorting the trilateral exercise as being directed at North Korea and maintained a firm readiness posture.
Latest Trends
The Freedom Edge exercise is also planned to be expanded in 2025. In June 2025, the defense ministers of South Korea, the United States, and Japan met at the Shangri-La Dialogue in Singapore and reaffirmed the policy of regularizing the exercise, and they are developing exercise scenarios that add cyber and space domains. So far, the trilateral exercise has centered on naval forces, but there are ongoing discussions to expand it to include ground forces, Marines, and Air Force special operations units, as well as weapons of mass destruction defense drills. In addition, if Japan's reconnaissance-strike weapon systems for standoff defense, scheduled to be introduced by the end of 2025, participate, more sophisticated operations can be expected. Some analysts predict that despite political variables such as the U.S. presidential election, trilateral security cooperation will be institutionalized and continue, while others point out that the possibility of a backlash from China should be monitored.
