The Columbia-class submarine (formerly known as the Ohio Replacement Submarine and SSBN-X Future Follow-on Submarine) is an upcoming class of nuclear submarines designed to replace the Ohio-class ballistic missile submarines in the United States Navy. The first submarine officially began construction on 1 October 2020, and is scheduled to enter service in 2031.
On 3 June 2022, the Navy announced that this first boat will be named U.S.S. District of Columbia (SSBN-826), because there currently exists an attack submarine named U.S.S. Columbia (SSN-771). The Navy did not say whether the name of the class will also be changed.
