Submarines.

The Columbia-class is the U.S. Navy's next-generation of nuclear-powered ballistic missile submarines (SSBNs) developed to replace the fourteen Ohio-class SSBNs that have formed the sea-based component of the U.S. nuclear triad since the early 1980s. Originally known as the Ohio Replacement Program (ORP) and SSBN(X), the class consists of twelve planned submarines that will gradually enter service beginning in the early 2030s while Ohio-class retirements occur at a rate of one submarine per year. Representing the U.S. Navy's highest acquisition priority, the Columbia-class will become the United States' primary strategic nuclear deterrent at sea once fully operational, with each submarine designed for a 42-year service life without reactor refueling and expected to conduct up to 124 strategic deterrent patrols before retirement.
