Hyundai Rotem Advances Firepower, Protection, and Mobility Technologies
South Korea’s Hyundai Rotem has successfully completed live-fire testing of its new 130 mm main gun, a core element of the K3 next-generation main battle tank. This marks a major leap in the tank’s firepower and sets the stage for the integration of next-gen technologies in armor, propulsion, and active protection—currently all under development. Despite the success, Hyundai Rotem confirmed there are no plans to rush the program. The focus remains on methodical R&D and validation.
The 130 mm gun is expected to deliver higher penetration, longer range, and more muzzle energy than the widely used 120 mm models—giving the K3 a decisive edge in future armored conflicts.
Protection-wise, the K3 will go beyond the K2 Black Panther, incorporating lightweight but stronger armor, potentially including nano-materials, reactive layers, and optimized structural design. This ensures high survivability without sacrificing mobility.

A next-generation powerpack—possibly hybrid-electric—is also under development, offering better energy efficiency, reduced thermal signature, and enhanced terrain handling. The APS suite, redesigned from the ground up, will feature AI-driven detection, radar-guided interceptors, and soft-kill defenses, putting the K3 on par with leading MBTs like the KF51 Panther and AbramsX.
While development continues, K2 tank exports to Poland proceed steadily at Hyundai Rotem’s production facilities. It was also clarified that the K3 images recently shown do not reflect the final configuration.
With a powerful gun, smarter armor, and advanced digital systems, the K3 is shaping up to become one of the most capable tanks of the next era in armored warfare.
