All the Ohio-class submarines, except for USS Henry M. The lead submarine of this class is USS Ohio. Although the Trident missiles have no preset targets when the submarines go on patrol, : 392 they can be given targets quickly, from the United States Strategic Command based in Nebraska, using secure and constant radio communications links, including very low frequency systems. The 14 SSBNs together carry about half of U.S. Air Force strategic bombers and intercontinental ballistic missiles. Like its predecessor Benjamin Franklin- and Lafayette-class subs, the Ohio-class SSBNs are part of the United States' nuclear-deterrent triad, along with U.S. At 20 Trident II missiles apiece, Ohio-class boats carry just as many missiles, if not more, than either the Borei class (16, 20 on the Borei II) or the recently deactivated Typhoon class (20). 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).
