General Dynamics Electric Boat will be given a $102.8 million modification to a Navy contract for developmental studies and design work related to Virginia-class submarines, the U.S. Department of Defense (DoD) announced in its Thursday report of military contracts.

All of the work Electric Boat will conduct will help to update and support the design and related drawings, and data related to each of the Virginia-class submarines. The design will include technology insertion throughout the construction periods. Electric Boat will also deliver “development studies and design efforts related to the Virginia-class submarine design and design improvements, preliminary and detail component and system design, integration of system engineering, design engineering, test engineering, logistics engineering, and production engineering,” according to the DoD.

More than $60 million in funds ranging from the 2010 to 2016 fiscal year will be assigned with the award, none of which will expire at the end of the 2015 fiscal year. Nearly all of the work will be conducted in Gorton, Conn., and should be finished by April 2016.
