An interesting documentary on US navy nuclear armed submarines produced by the pentagon channel. Composition of the current force[edit] Ohio class (18 in commission) — 14 ballistic missile submarines (SSBNs), 4 guided missile submarines (SSGNs) Virginia class (11 in commission, 5 under construction, 2 on order) — fast attack submarines Seawolf class (3 in commission) — attack submarines Los Angeles class (43 in commission, 2 in reserve) — attack submarines Fast attack submarines The U.S. has 43 Los Angeles-class submarines on active duty and 19 retired, making it the most numerous nuclear-powered submarine class in the world. The class was preceded by the Sturgeon class and followed by the Seawolf and Virginia classes. Except for USS Hyman G. Rickover (SSN-709), submarines of this class are named after U.S. cities, breaking a Navy tradition of naming attack submarines after sea creatures. The final 23 boats in the series, referred to as "688i" boats, are quieter than their predecessors and incorporate a more advanced combat system.[18] These 688i boats are also designed for under-ice operations: their diving planes are on the bow rather than on the sail, and they have reinforced sails. Ballistic and guided missile submarines The U.S. has 18 Ohio-class submarines, of which 14 are Trident II SSBNs (Ship, Submersible, Ballistic, Nuclear), each capable of carrying 24 SLBMs. The first four which were all equipped with the older Trident I missiles have been converted to SSGN's each capable of carrying 154 Tomahawk guided missiles and have been further equipped to support Special Operations (SEALS). If the maximum of 154 Tomahawk missiles were loaded, one Ohio-class SSGN would carry an entire Battle Group's equivalent of cruise missiles. Ballistic missile submarines (SSBNs or boomers in American slang) carry submarine-launched ballistic missiles (SLBMs) with nuclear warheads for attacking strategic targets such as cities or missile silos anywhere in the world. They are currently universally nuclear-powered to provide the greatest stealth and endurance. They played an important part in Cold War mutual deterrence, as both the United States and the Soviet Union had the credible ability to conduct a retaliatory strike against the other nation in the event of a first strike. This comprised an important part of the strategy of Mutual Assured Destruction. In order to comply with arms reduction against the START II treaty, the U.S. Navy modified the four oldest Ohio-class Trident submarines (Ohio (SSGN-726), Michigan (SSGN-727), Florida (SSGN-728), and Georgia (SSGN-729)) to SSGN (Ship, Submersible, Guided, Nuclear) configuration. The conversion was achieved by installing vertical launching systems (VLS) in a configuration dubbed "multiple all-up-round canister (MAC)." This system was installed in 22 of the 24 missile tubes, replacing one large nuclear strategic ballistic missile with 7 smaller Tomahawk cruise missiles. The 2 remaining tubes were converted to lockout chambers (LOC) to be used by special forces personnel who can be carried on board. This gives each converted sub the capability to carry up to 154 Tomahawk missiles. The MAC tubes can also be used to carry and launch UAVs or UUVs which give the ship remote controlled "eyes & ears" allowing the ship to act as a forward-deployed command & control center. Despite the increase in stand-off strike capabilities, this conversion counts as an [19][20] because it reduces the number of nuclear weapons that are forward-deployed.[clarification needed] The American George Washington-class "boomers" were named for patriots, and together with the Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes, these SSBNs comprised the Cold War-era "41 for Freedom." Later Ohio-class submarines were named for states (recognizing the increase in striking power and importance once bestowed upon battleships), with the exception of Henry M. Jackson (SSBN-730), which was named for United States Senator Henry M. "Scoop" Jackson (1912–1983) of Washington upon his death while in office (1983). This honor was in recognition of his advocacy on behalf of the nuclear submarine program. He strongly supported the rapid development of nuclear submarines and especially the development of an SSBN program. Senator Jackson also called for the establishment of a Deputy Chief of Naval Operations for Undersea Warfare because he believed submarines were "lost in a welter of naval bureaucracy." Personnel[edit] U.S. Navy submarines are manned solely by volunteers from within the Navy.[21] Because of the stressful environment aboard submarines, personnel are accepted only after rigorous testing and observation, as a consequence submariners have significantly lower mental hospitalization rates than surface ship personnel.[22] Furthermore, submariners receive submarine duty incentive pay (SUBPAY) in addition to sea pay.[23]
