General Dynamics Electric Boat Corp. of Groton, Connecticut, was awarded a $642.3 million fixed-fee, cost-reimbursement modification to a previously awarded contract for lead plant support and research related to Virginia-class submarines.

Work will be performed primarily in Groton (94%), with additional work in McLeansville, North Carolina (3%), Newport News, Virginia (2%), and Newport and Quonset, Rhode Island (1%). The project is expected to be completed by April 2026.

Under a separate contract, General Dynamics Electric Boat was awarded a $42.4 million cost-plus-fixed-fee modification for unique parts and specialized materials for Virginia-class submarines, including initial spares. This work will be performed in Groton and is expected to be completed by March 2030.

Additionally, General Dynamics Mission Systems Inc., located in Scottsdale, Arizona, was awarded a $13.4 million contract modification for work on military space systems architecture, ground control and integration, and operations and maintenance. This modification increases the total contract value to $1.17 billion from $1.15 billion.
