The US Navy has awarded a new contract modification worth $126.1m for continued development of the common missile compartment (CMC) for the Columbia-class submarine.
Contracted company Electric Boat will also be responsible for developing the CMC for the UK Royal Navy’s Successor-class ballistic missile submarine (SSBN). Electric Boat is a wholly owned subsidiary of General Dynamics.
The scope of the new contract modification also includes funding for the acquisition of long-lead-time material for the missile tubes, which will be integrated into the new SSBNs of the navies of the two nations, in addition to the UK Navy’s Dreadnought strategic missile submarine.
The original $5.1bn contract was awarded to General Dynamics Electric Boat last September.
Under the 14-year contract, the company was contracted to carry out design and development work for the US Navy’s new and advanced ballistic missile submarine, which is slated to commence construction in late 2020.
The overall potential value of the complete Integrated Product and Process Development (IPPD) contract is $6.1bn.
Managed Program Executive Office (PEO) Submarines, the Columbia-class programme involves the construction of a total of 12 vessels, which have been designed specifically to replace the US Navy’s existing Ohio-class nuclear ballistic submarine force.
The first patrol of the lead Columbia-class vessel, SSBN 826, is slated for the fiscal year 2031.
Last December, the company received a $432m contract modification to deliver research and development, as well as lead-yard services for the US Navy’s Virginia-class nuclear-powered attack submarines.
