Electric Boat continues work on Columbia class
General Dynamics Electric Boat has secured a $869 million contract modification from US Naval Sea Systems Command for continued design completion, engineering work, affordability studies and design support efforts associated with Columbia-class ballistic missile submarines (SSBNs).
The modification, announced on 22 June, also includes a $9.47 billion option supporting design, construction and engineering support for the first two Columbia-class boats.
Work will be completed by December 2031 at various locations in the US, principally Groton in Connecticut (41%).
The contract modification covers industrial base development and expansion efforts as part of the integrated enterprise plan and multiprogramme material procurement supporting nuclear shipbuilding programmes, including the Columbia-class and Virginia-class SSBN programmes, as well as the Gerald R Ford-class aircraft carriers.
The modification provides additional UK Strategic Weapon Support System kit manufacturing and efforts to support expansion of the domestic missile tube industrial base.
