Marinette Marine

Marinette Marine Corporation (MMC) was founded on the Menominee River in Marinette, Wisconsin, in 1942 as part of the growth in the American shipbuilding industry during World War II.

In 2000, Marinette Marine, a privately held company, was purchased by The Manitowoc Company for approximately $48 million. In August 2008, the Manitowoc Company announced that it had signed an agreement to sell their Manitowoc Marine Group division, which includes Marinette Marine, to Fincantieri Marine Group Holdings, Inc. and minority investor Lockheed Martin. The sale was completed in January 2009, to Fincantieri. The net purchase price in the all-cash deal was approximately $120 million.

Since its founding, Marinette Marine has produced more than 1,300 vessels. While primarily a producer of commercial vessels, it has also taken a number of contracts for the United States Navy, primarily for auxiliary vessels. Most recently, Marinette Marine became part of a team with Lockheed Martin to produce one of two littoral combat ship designs for the Navy, resulting in the launch of the USS Freedom in September 2006. In 2010, Marinette Marine bid for work on the Ship-to-Shore Connector, which would replace the Landing Craft Air Cushion (LCAC).

In April 2020, it was announced that Fincantieri Marinette Marine had won the contract to produce the United States Navy new Constellation-class multimission guided-missile frigate.

In 2019, Vice President Mike Pence and Secretary of Labor Eugene Scalia spoke at Marinette Marine Shipyard, praising the Trump administration's support for American manufacturing industries and vocational education. One year later, during the 2020 presidential election, President Donald Trump held a re-election rally at the shipyard, with Wisconsin State Assembly representatives John Nygren and Mary Felzkowski touting his administration's manufacturing policy, military expansion, and the United States–Mexico–Canada Agreement.

As of 2023, Fincantieri Marinette Marine is planning to overhaul and expand its yard facilities as part of winning a contract to construct the Constellation-class frigates. The changes will accommodate the larger size of the frigates versus the littoral combat ships, and will alter the way the yard launches ships.

All Marinette Marine facilities are located on the Menominee River in Marinette, Wisconsin. Some of the specific facilities they comprise are as follows:

300,000 square feet (30,000 m2) of indoor ship construction space

53,000 square feet (4,900 m2) of indoor warehousing and receiving space

Ship launching facility for up to 4,500 long tons
