South Korean Military Completes Upgrading K1A1 Tanks to K1A2 Standard

South Korea’s Defense Acquisition Program Administration (DAPA) announced on September 12 that it has completed the upgrade of all K1A1 tanks in the South Korean Army and Marine Corps to the K1A2 standard.

This upgrade was carried out as part of the fourth mass production contract for the K1A2 tank, which began in November 2021 and concluded in September 2024.

The K1A2 is designed to enable integration with other ground weapon systems, including the K2 tank and K21 infantry fighting vehicle.

Key upgrades include the installation of a battlefield management system, a new identification friend or foe (IFF) device, and surveillance cameras for both front and rear views. The battlefield management system has replaced the older analog communication setup with a digital system, allowing for real-time information sharing and battlefield visualization via digital maps. This system works in conjunction with the Ground Tactical Data Link (KVMF: Korea Variable Message Format), enabling rapid and accurate tactical data exchange between various ground-based systems, including tanks, helicopters, and unmanned aerial vehicles.

The IFF device helps to prevent friendly fire incidents by clearly distinguishing between friendly and enemy forces on the battlefield. The results are displayed on the battlefield management system's interface, allowing for quick identification and reducing the risk of misfires.

The front and rear surveillance cameras enhance operational safety by allowing the tank crew to monitor their surroundings without exposing themselves to external risks. This feature is especially useful during closed-hatch maneuvers, improving visibility and reducing the chances of non-combat accidents.
