under construction

The U.S. Navy awarded General Dynamics a $15.4 billion contract to support the construction of 12 nuclear-powered, nuclear ballistic missile-armed Columbia-class submarines to replace the aging Ohio-class boats. The program includes design, class lead yard support and sustainment, integrated enterprise plan initiatives, and submarine industrial base supplier development enhancement efforts. The total program cost is estimated to exceed $126 billion, with General Dynamics responsible for building 78% of each submarine and Huntington Ingalls building the bow and stern portions.
