General Dynamics Electric Boat awarded Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division $567.6 million to provide long-lead-time material and advance construction activities for Columbia-class ballistic missile submarines.
HII is currently under contract for construction of submarine modules for Build I, the first two submarines in the class: District of Columbia (SSBN 826) and Wisconsin (SSBN 827). The advance procurement funds from this subcontract modification, awarded April 4, will allow NNS to purchase major components and commodity material and to begin advance construction on Build II, the next five submarines in the class.
Ultimately, the Columbia class will replace the fleet of Ohio-class ballistic missile submarines, and take over the role of the nation’s sea-based strategic deterrent.
NNS is a major shipbuilding partner in the Columbia-class program, constructing and delivering six module sections per submarine under contract to General Dynamics Electric Boat.
