Ohio-class Submarines (documentary)

The Ohio class is a class of nuclear-powered submarines used by the United States Navy. The navy has 18 Ohio-class submarines: 14 ballistic missile submarines (SSBN) and four that were later converted to guided missile submarines (SSGN). The Ohio class is named after the lead submarine of this class, USS Ohio. The 14 Trident II SSBNs together carry approximately fifty percent of the total US active inventory of strategic thermonuclear warheads. The exact number of warheads deployed in the oceans of the world varies in an unpredictable and classified manner, always at or below a maximum number set by various Strategic Arms Reduction Treaties. Although the Trident missiles have no pre-set targets when the submarines go on patrol, the warships, when required, are capable of quickly being assigned targets by using secure and constant radio communications links at sea, including very low frequency (VLF) systems.
