South Korea’s Hyundai Rotem has launched development of the K3 main battle tank, envisioned as the successor to the K2. Supported by key defense agencies, the platform will first feature a hydrogen-diesel hybrid engine, with a long-term goal of moving to an entirely hydrogen-powered configuration.
The adoption of hydrogen fuel cells is anticipated to deliver several operational advantages—such as quieter operation, lower heat signatures, better fuel economy, and increased mobility—ultimately enhancing the tank’s performance and reducing maintenance needs.
