Summary:
The United States is ready to deploy a dedicated 5G mobile military network in South Korea, starting at Oson Air Base, as an important step to share real -time information during joint operation and strengthen collaborative defence abilities. In June 2025, through an agreement with the Korean government, this strategic initiative was formally aligned with a wider American joint all-domain command and control (JADC2) concept. Plans are underway to increase this advanced 5G network for major Indo-Pacific colleagues, including Japan and Australia, promoting an integrated, AI-operated military network throughout the region.
How the U.S. and South Korea’s 5G military network will revolutionize defence collaboration:
In a significant progress towards increasing military differences and real -time operating capabilities, the United States is setting up a 5G mobile military network in Korea, in an agreement with the South Korean government. It is designed to facilitate the immediate information sharing during high speed, low-distance network joint operations, enhancing the associate forces associate defence currency. Initial deployment is slate to the Oson Air Base of the Joint Force Command at Pyongtech, Gyongi province, a strategically important hub for the United US fighter jets and arms in the region. A blueprint for this project is currently being prepared, in which the implementation is set to start within the next year.
This initiative is the cornerstone of a broad American strategy to strengthen military alliances and expand advanced networking capabilities in India-Pacific. There are obvious intentions to expand this 5G network to include other major colleagues such as Japan and Australia, which create more interconnected and flexible defence structures. Such expansion is important to carry forward the combined all-domain command and control (JADC2) concept, an US Defence Department (DOD) is mandatory to integrate the sensors and systems from all branches of armed forces to integrate, integrate, AI-powered networks. This integration will enable fast decision making and more synchronized reactions in air, land, sea, location and cyberspace domains.
The choice of Osan Air Base for the initial rollouts underlines its vast strategic importance as a fundamental American establishment in the region, for the Kadeena Air Base in Okinawa. Officials of both American and South Korea have expressed aspirations to expand this 5G network to include other American military bases in the Korean peninsula. The deployment of a dedicated military 5G network provides several benefits for defence works. It provides real-time video feeds, high-resolution sensor data transmission, and high bandwidth and ultra-lo delays required for instant communication, which are important to increase awareness and accelerate decisions on the battlefield.

In addition, 5G technology is important to enable advanced military applications such as distant operation of unmanned military systems, the view of the battleground (AR) and artificial intelligence-managed decision support systems. A safe and flexible 5G network ensures that sensitive data remains preserved and this operation moves without any interruption, even in hostile environment. This strong connectivity is also necessary to improve logistics and supply chain management through real-time tracking and monitoring of military assets.
