Hanwha forges partnerships at U.S. defense expo for naval, rocket development collaborations

Coverage Comparison

Two reports from Yonhap News, South Korea's leading wire service, detailed Hanwha Group's announcements at the Sea-Air-Space 2026 exposition held in National Harbor, Maryland, in late April. The first article, published April 21, focused on a strategic partnership with Magnet Defense to jointly develop medium unmanned surface vessels (MUSVs) for the U.S. military. The second, published April 22, covered additional memorandums of understanding (MOUs) with Leidos Gibbs & Cox for shipbuilding and Northrop Grumman for rocket propulsion development. Both reports framed the announcements as part of Hanwha's broader effort to strengthen its presence in the U.S. defense industrial sector.

Key Claims

According to Yonhap, Hanwha Defense USA, Hanwha's U.S. subsidiary, and Magnet Defense signed an MOU at the expo to collaborate on the development and production of MUSVs. The vessels are designed to operate without onboard crews and perform missions such as surveillance, logistics, and combat support. The agreement includes producing a 38-meter MUSV for potential supply to the Pentagon, based on Magnet Defense's M48 platform combined with Hanwha's shipbuilding and defense technologies.

The report quotes Hanwha Defense USA CEO Michael Coulter as saying the partnership allows Hanwha to utilize its manufacturing capacity and advanced robotics, paired with Magnet Defense's proven autonomy and technology. Marc Bell, CEO of Magnet Defense, is quoted as saying that Hanwha's advanced missile systems, coupled with Magnet Defense's designed and built MUSVs, make for a powerful combination.

Separately, Yonhap reported that Hanwha Ocean signed an MOU with Leidos Gibbs & Cox, a U.S. naval architecture firm, to strengthen shipbuilding capabilities for the U.S. Navy and allied forces. Leidos Gibbs & Cox has designed more than 70 percent of U.S. Navy surface vessels since World War II, according to the report. The companies plan to cooperate on vessel designs optimized for U.S. Navy requirements, joint development of next-generation ships, and building supply chains leveraging production bases in both South Korea and the United States.

In another development, Hanwha Aerospace signed an MOU with Northrop Grumman to collaborate on developing a first-stage solid-fuel rocket for the AReS missile system. AReS, which stands for advanced reactive strike, is a ground-launched long-range missile system under development by Northrop Grumman that requires advanced propulsion for rapid maneuvering and launch. Hanwha Aerospace will participate in early-stage development of the system's first-stage propulsion unit, the company said.

Perspectives

Hanwha Group's perspective, as conveyed through company statements and official announcements, emphasizes the strategic value of these partnerships in enhancing its manufacturing and technological capabilities, and expanding its foothold in the U.S. defense market. The U.S. partner companies view the collaborations as leveraging complementary strengths, with Magnet Defense highlighting Hanwha's missile systems and manufacturing prowess, and Leidos Gibbs & Cox focusing on naval architecture expertise.
