[조선 밸류체인 줌인] 포스코, 철강 기술로 'K-방산' 공급망 진입

POSCO's naval-grade steel technology addresses the critical engineering challenge of balancing strength, ductility, and lightweight properties required for submarine and naval applications—a gap that has long limited Korea's defense manufacturing capabilities. With KR certification and proven performance advantages over competitors, this breakthrough opens pathways for K-defense export and positions POSCO as a strategic materials supplier rather than a commodity steel producer. The potential integration with existing high-manganese steel expertise could further accelerate Korea's indigenous defense supply chain development.
