Marinette Marine Corporation (MMC)
Marinette Marine Corporation (MMC) was founded along the Menominee River in Marinette, WI in 1942 to meet America's growing need for naval construction. Since our first contract to build five wooden barges, MMC has built more than 1,300 vessels. MMC is a full service shipyard with in-house capabilities to design and construct the most complex vessels. It has earned an international reputation for its ability to build technologically advanced vessels.
The ability to construct the entire vessel indoors plays a major role in the quality of the finished product and the contractor's efficiency. At MMC, vessels are constructed and outfitted completely indoors. When ready for launching, they are moved outdoors. Typically, vessels are 90 to 95% material and labor complete when launched.
Stringent production and performance standards require a quality-minded corporate culture and work ethic backed by comprehensive quality assurance and testing programs. Efficiencies in production are achieved by constructing the vessels in a systematic series of panels, modules, and blocks. This technique allows the modules and blocks to be pre-outfitted to a very high degree, while internal compartments are still very accessible.
MMC's in-house engineering staff and skilled craftsman excel in highly efficient, modular, subassembly and assembly line manufacturing methods. Our integrated engineering methods and project management systems have enabled the shipyard to progressively build larger and more complex vessels. Because of the company's ability to deliver ships ahead of schedule and within contracted costs, the Navy has designated MMC a premier supplier.
Littoral Combat Ship (LCS), which is the Navy's first focused-mission ship, will be used for anti-submarine warfare, surface warfare, and mine warfare missions. The ship will be 378 feet long with a beam of 57 feet, and its top speed will range from 45 to 60 knots, depending on its load. The ship's innovative design allows it to turn 360 degrees in less than eight lengths at top speed and to accelerate to full speed in less than two minutes. Marinette Marine to build the lead ship.
The new Great Lakes Icebreaker, which will be named Mackinaw, will be approximately 240 feet long, 60 feet wide, and will displace 3,500 long tons. In addition to breaking ice to keep shipping lanes open on the Great Lakes, the multi-mission vessel will service aids to navigation, as well as performing search and rescue, pollution control, security, and law enforcement duties from its homeport of Cheboygan, Michigan. The icebreaker will be built at Marinette Marine.
As part of the initial Improved Navy Lighterage System (INLS) contract, to build 29 barges that can be assembled into floating platforms or causeway systems to transport heavy materials such as tanks, trucks, and cargo between ship and shore. Each barge will be approximately 80 ft. by 24 ft., will weigh between 75 and 124 tons, and will be capable of carrying approximately 150 tons of cargo. Six of the 29 barges will be powered by 360-degree rotating water-jet thrusters for propulsion and station-keeping.
