POSCO has localized special steel technology by developing the first high-ductility and bulletproof steel for naval ships in Korea, receiving classification approval from the Korean Register (KR) in January. The high-ductility steel improves elongation by 35% and impact absorption by 58% during collision simulations, enhancing survivability.

The ballistic steel developed is approximately 30% thinner than conventional plates, securing protection against external threats while reducing superstructure weight. This project is the result of several years of joint research and aims to enhance the performance of the South Korean Navy's vessels and expand into overseas markets.
