Under the modification, Electric Boat will maintain and update design drawings and data, including technology insertions, for all Virginia-class submarines throughout their construction and post-shakedown availability periods.

 

Initially awarded in October 2005, the contract will be worth a total of $225m when it is completed in September 2007.

 

Electric Boat and its construction partner, Northrop Grumman Newport News, have delivered two ships of the class to the Navy; USS Virginia SSN-774 in October 2004 and USS Texas SSN-775 in June 2006.  Eight additional submarines are under contract.
