Huntington Ingalls Industries said Tuesday its Newport News Shipbuilding had secure a roughly $200 million subcontract modification to provide long-lead components, including commodities materials, and labor for the Columbia-class ballistic missile submarine.
Huntington Ingalls is a major subcontractor on General Dynamics Electric Boat’s roughly $5 billion Naval Sea Systems Command prime contract to develop and build 12 Columbia-class ballistic-missile submarines that will replace 18 existing Ohio-class submarines.
Like Ohio boats, Columbia-class subs will carry Trident II-D5 missiles tipped with W76 warheads provided by the Department of Energy’s National Nuclear Security Administration (NNSA).
Huntington Ingalls also works at a few major NNSA sites, including the Los Alamos National Laboratory, which designed the W76. Huntington Ingalls is a major industry subcontractor for lab operator Triad National Security, which took over management Nov. 1.
