S. Korea to upgrade integrated military command network for 1st time in 10 years

South Korea is preparing its first major upgrade in a decade of the Allied Korea Joint Command and Control System (AKJCCS), the central platform for combined operations with the United States, which maintains 28,500 troops on the peninsula to deter a possible North Korean attack. The overhaul is set to begin in the second half of the year, according to the Defense Acquisition Program Administration.

A bid notice to select the main contractor for the platform overhaul was issued last month, stating that the project "seeks to equip the current system with new capabilities needed to support combined operations led by South Korea’s military after the transition of wartime operational control," also known as OPCON.

Developed in 2012, the AKJCCS is currently used by the ROK-U.S. Combined Forces Command, the Joint Chiefs of Staff in Seoul and field units across the military. The system serves as the digital backbone of the U.S.-ROK alliance, enabling joint forces to share intelligence, coordinate actions and manage operations on the Korean Peninsula. This marks the system’s first major revision since its launch.

A budget of 117.8 billion won ($84.9 million) has been allocated for the upgrade, which will introduce cloud-based servers, artificial intelligence (AI)-assisted automation, real-time interpretation tools, secure video links and enhanced cybersecurity to the aging infrastructure, with a key objective being to enhance the South Korean military’s ability to lead combined operations in preparation for the transfer of OPCON from the U.S. to the South.

Although no date has been set for the transfer of wartime operational control, officials from both governments say the transition will hinge on verified progress in surveillance, command capabilities, secure communications and information-sharing. The upgrade is described as a step toward meeting those conditions, but not an indication that the transfer is imminent.

The planned transfer of OPCON remains a divisive issue, reflecting a broader debate between advocates of national sovereignty and those wary of weakening the U.S.-led security framework. During his confirmation hearing before the National Assembly’s Defense Committee last month, Defense Minister Ahn Gyu-back stated that the government aimed to complete the transfer within the current administration, a remark he later clarified, saying it was intended to reaffirm the administration’s commitment to the long-delayed transition rather than setting a hard deadline.

The AKJCCS operates independently of the U.S.-led Combined Enterprise Regional Information Exchange System-Korea network. While the two systems serve similar functions, American military officials have repeatedly voiced concerns about cybersecurity vulnerabilities in South Korea’s network. The planned enhancements include stronger safeguards to address these concerns and improve interoperability between allied forces.

The upgraded system will feature AI tools designed to automate operational reporting and ease the workload for personnel. It will also feature automatic translation and interpretation, enabling South Korean and American forces to coordinate in real time, independent of separate language support.

Another key enhancement is the introduction of a secure video conferencing platform, allowing commanders to communicate across locations without direct access to military networks. The shift to a cloud-based infrastructure is expected to make the system more flexible and scalable than the current hardware-dependent model.

Officials stressed that the upgrade is not tied to a specific timeline for OPCON transfer. Instead, it reflects an effort to prepare for the conditions that have been agreed upon by both countries in the event of an emergency. Currently, South Korea exercises peacetime control over its military, whereas the U.S. commander of the Combined Forces Command would take charge in wartime.

The project is expected to be completed by 2027. The system will undergo phased evaluations involving both South orean and U.S. military authorities.
