Summary The Columbia-class program's goal is to design and build a class of 12 new ballistic missile submarines ( SSBNs ) to replace the Navy’s current force of 14 aging Ohio-class SSBNs. The Ohio-class submarines were designed to have a service life of 42 years (two 20-year cycles with a 2-year midlife nuclear refueling period). As the Ohio-class SSBNs were first deployed in 1981, they will start reaching the end of their service between 2027 and 2040, at a rate of about one boat per year. Starting in 2031

Since then, the program has been referred to as the Columbia Class program, and the boats as Columbia-Class Submarines. The Columbia-class was
