Founded in 1942 to support wartime naval construction, Fincantieri Marinette Marine has become one of the main Great Lakes yards serving U.S. Navy, U.S. Coast Guard, and foreign military ship programs. Fincantieri says the yard has designed and built more than 1,500 vessels and operates with modular and assembly-line production methods for steel naval and government ships.

The yard entered the Fincantieri group in January 2009 when Fincantieri completed its acquisition of Manitowoc Marine Group. The transaction created Fincantieri Marine Group as a U.S. subsidiary with Wisconsin shipyards and related facilities, and Fincantieri described the move as a way to enter the U.S. defense market while investing in modern ship design, production processes, facilities, and workforce training.

In current naval procurement, the Marinette yard is associated with the Freedom-variant Littoral Combat Ship production line, the four-ship Saudi MMSC program, and the U.S. Navy's Constellation-class frigate work. The Navy's December 2025 Constellation fact file says Marinette Marine Corporation, also known as Fincantieri Marinette Marine, would continue building Constellation and Congress after the Navy shifted away from the broader frigate program.
