WASHINGTON — The U.S. Navy announced Thursday it had inked a $9.47 billion contract with builder General Dynamics Electric Boat for the full construction cost of the lead boat of the Columbia-class ballistic missile submarine, as well as advanced procurement money for the second boat, the future USS Wisconsin.

The announcement marks the end of the beginning for the Columbia class, which the Navy has for years said is its top priority. The 12-ship class will replace the retiring Ohio-class submarines. The Columbia is slated to make its first patrol in 2031, and the Navy says it must meet the timeline to maintain continuous sea-based deterrent patrols.
