They are the world's third-largest submarines, behind the Russian Navy's Soviet-designed 48,000-ton Typhoon class and 24,000-ton Borei class. Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs).

The COLUMBIA class will be the largest, most capable and most advanced submarine produced by our nation. Representing a generational recapitalization of the SSBN force, COLUMBIA class will ensure continuous sea-based strategic deterrence into the 2080s. The COLUMBIA Class SSBN is the nation’s future Sea Based Strategic Deterrent, is the Navy’s number one acquisition priority, and will provide the most survivable leg of the Nation’s strategic triad. It replaces the currently serving OHIO Class SSBNs and must be constructed and delivered on schedule beginning in FY2027 to meet United States Strategic Command requirements.
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. Each SSBN has two crews, Blue and Gold, which alternate manning the submarines and taking them on patrol. On average, the submarines spend 77 days at sea followed by 35 days in-port for maintenance. The Ohio-class design allows the submarines to operate for 15 or more years between major overhauls.
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. SSBNs are specifically designed for extended deterrent patrols. 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.
However, under provisions of the New Strategic Arms Reduction Treaty, each submarine has had four of its missile tubes permanently deactivated and now carry a maximum of 20 missiles. They are designed specifically for stealth and the precise delivery of nuclear warheads.Įach of the 14 Ohio-class SSBNs originally carried up to 24 SLBMs with multiple, independently-targeted warheads. The Navy's ballistic missile submarines, often referred to as "boomers," serve as an undetectable launch platform for submarine-launched ballistic missiles (SLBMs).
