Newport News Shipbuilding has delivered the stern for firstinclass submarine District of Columbia (SSBN 826) to General Dynamics Electric Boat. This marks a major milestone for the U.S. Navy’s Columbiaclass submarine program. The unit was transported by barge to Electric Boat’s facility in Quonset Point, Rhode Island. Take a moment to watch this timelapse video showing the historic move as shipbuilders transport the unit from an NNS production facility to a barge and out into the James River.
