Huntington Ingalls Industries (HII) announced today that its Newport News Shipbuilding division has been awarded a contract modification from General Dynamics Electric Boat (GDEB) in support of construction on the first two Columbia-class ballistic missile submarines.
The contract modification, valued at approximately $2.2 billion, provides continued design support efforts, as well as the construction and delivery of six module sections for each of the first two Columbia-class submarines.
GDEB has won $19 billion to build and test two vessels of this class earlier this month. The Columbia-class nuclear-powered ballistic missile submarine will be the largest submarine ever built by the United States.
As part of the contract, Newport News will deliver the completed modules to Electric Boat for final assembly. The contracted module delivery dates are scheduled to start in November 2022 with the last module delivery taking place by January 2028.
Newport News is a major contractor and shipbuilding partner in the Columbia-class program, and in May 2019 began advance construction activities on the lead ballistic missile submarine under contract to Electric Boat.
The Columbia class will replace the fleet of Ohio-class ballistic missile submarines. The lead ship is scheduled to be delivered to the Navy in 2027.
