Marinette Marine

What Marinette Marine does

Marinette Marine Corporation is a U.S. shipbuilding company founded in 1942 and headquartered along the Menominee River in Marinette, Wisconsin. The company constructs naval and specialized commercial vessels, with a portfolio that includes large unmanned surface vehicles (LUSV), medium unmanned surface vehicles (MUSV), and extra-large unmanned undersea vehicles (XLUUV/Orca) for the U.S. Navy, as well as specialized commercial platforms such as the offshore wind installation vessel Charybdis, which cost upwards of $715 million. The company is a subsidiary of Huntington Ingalls Industries, the largest military shipbuilding company in the United States, and participates in the Boeing-led XLUUV program alongside its parent.

The company's core business revolves around shipbuilding and naval vessel construction, with technical capabilities centered on industrial maritime manufacturing for defense and specialized commercial applications. Long-tenured yard infrastructure and a specialized craft workforce form the production backbone, though the broader U.S. shipbuilding labor pool faces structural challenges, including an industry-average workforce age of 50.

Marinette Marine generates revenue primarily through long-cycle, contract-based U.S. Navy procurement, including cost-plus and fixed-price arrangements, with vessels delivered directly to government customers through defense acquisition programs. Its go-to-market is enterprise field sales via competitive bidding and sole-source awards, anchored almost exclusively to the U.S. Navy and Department of Defense as a customer segment. The company is positioned to benefit from domestic maritime policy initiatives such as the SHIPS for America Act and the Maritime Action Plan, which seek to expand the U.S.-flagged fleet from 80 to 250 vessels and revitalize the U.S. maritime industrial base.
