Hanwha Ocean and Leidos to strengthen U.S. and allied naval shipbuilding

Hanwha Ocean and Leidos (NYSE: LDOS) are collaborating to advance next-generation naval ship design, strengthen U.S. shipbuilding capacity, and pursue opportunities across global defense markets.

Hanwha Ocean’s world-class shipbuilding, combined with Leidos’ naval design and engineering expertise, is intended to deliver scalable, production-ready solutions aligned with evolving U.S. Navy and allied needs. The companies plan to focus on:

• Adapting Hanwha ship designs for full alignment with U.S. Navy standards and requirements
• Co-developing next-generation surface combatant concepts for U.S. and global markets
• Establishing a resilient, distributed supply chain across U.S. and Korean industrial bases
• Advancing ship designs optimized for rapid, efficient production and long-term sustainment

Hanwha Ocean brings world-class shipbuilding and naval vessel production capabilities, supported by decades of experience in designing, building, and maintaining advanced vessels, including submarines and surface combatants. Its U.S. subsidiary, Philly Shipyard, is emerging as a key contributor to the 2025 U.S.–Korea shipbuilding cooperation framework and is expected to play a growing role in future naval programs.

Leidos brings advanced maritime technologies, including International Class combatants, U.S. Navy-validated maritime autonomy software, and autonomous vessels such as Sea Archer, Sea Specter, Sea Ranger, and Sea Hunter. Leidos Gibbs and Cox has designed more than 70% of U.S. Navy surface combatants since World War II and remains one of the Navy’s most trusted design partners.

“This MOU will be a pivotal opportunity for Hanwha Ocean to secure a decisive technological edge not only in the U.S. market but also across the global naval shipbuilding arena. By collaborating with Leidos, we will accelerate our expansion into the global maritime defense market and deliver tangible results.” said Charlie SC Eoh, President of Naval Ship Business at Hanwha Ocean.

“Leidos has been a trusted partner to the U.S. Navy for decades,” said Mike Rickels, Leidos senior vice president for maritime. “By working with Hanwha, we’re extending that legacy, combining proven design expertise with world-class manufacturing capabilities to deliver ships that are designed for today’s missions and adaptable for the future.”
