Currently, the U.S. SSBN force consists of 14 Ohio-class submarines.  Built between 1974 and 1997, they remain ready, in a secure and survivable posture to strike if needed. 

Ohio-class SSBNs can carry up to 24 submarine-launched ballistic missiles (SLBMs) with multiple independently-targeted warheads. The SSBN’s strategic weapon is the Trident II D5 missile, which provides increased range and accuracy over the now out-of-service Trident I C4 missile.

Ohio-class SSBNs are specifically designed for extended deterrent patrols. To decrease the amount of time required for replenishment and maintenance, Ohio-class submarines have three large-diameter logistics hatches that allow sailors to rapidly transfer supply pallets, equipment replacement modules and machinery components thereby increasing their operational availability.

The Ohio-class SSBNs are home ported in Kings Bays, Georgia and Bangor, Washington. On average, the submarines spend 77 days at sea followed by 35 days in-port for maintenance. Each SSBN has two crews, Blue and Gold, which alternate manning the submarines while on patrol. This maximizes the SSBN’s strategic availability, reduces the number of submarines required to meet strategic requirements and allows for proper crew training, readiness, and morale.
