Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division has cut the first steel for the future USS Columbia, the lead boat of a new class of ballistic missile submarines ordered for the US Navy.

The future Columbia and its sisters are also the first class of submarines that will be built using fully digital blueprints.
