The USCGC MACKINAW (WLBB-30) was built by Marinette Marine Corporation, a subsidiary of Manitowoc Marine Group. The cutter was assembled indoors in the Vessel Erection Building. This allowed the vessel to be assembled and outfitted in controlled conditions, then moved outside to the launch ways.
The cutter was constructed in a planned system of modules or blocks that are fabricated and pre-outfitted prior to being moved to the erection building. This method of construction is extremely efficient as it provides easy access to equipment, components, and spaces. The modules are essentially complete prior to final assembly.
