GROTON, Conn., Nov. 25 (UPI) -- The U.S. Navy has awarded General Dynamics Electric Boat a $102.8 million contract modification to develop Virginia-class attack submarines.

Under the contract, General Dynamics subsidiary Electric Boat will provide research, development and lead-yard services for the submarines, as well as evaluate the new technology being used to produce the vessels. The contract modification brings the cumulative value of the company's contract with the U.S. Navy to $1.1 billion.
