Hyundai Rotem, a subsidiary of South Korea’s Hyundai Group, has announced a pioneering development for the Republic of Korea (ROK) Army: a hydrogen-powered K3 main battle tank. Set to be among the most advanced military vehicles in the world, the K3 aims to redefine future warfare by leveraging eco-friendly fuel cells, autonomous technologies, and advanced firepower.
Hyundai Rotem’s K3 project is a collaborative effort with South Korea’s Agency for Defence Development and other national research institutions, with production tentatively scheduled to begin by 2040. The shift to hydrogen marks a historic step in South Korea’s commitment to reduce reliance on traditional combustion engines in defence equipment. The K3’s hydrogen fuel cell will eventually replace the diesel engines of the ROK’s K-series tanks, beginning with hybrid prototypes that combine hydrogen and diesel power.
