This role was formerly filled by the decommissioned USS Parche (SSN-683). The MMP may also be used as an underwater splicing chamber for tapping of undersea fiber optic cables. The USS Jimmy Carter is roughly 100 feet (30 m) longer than the other two boats of her class due to the insertion of a section known as the Multi-Mission Platform (MMP), which allows launch and recovery of ROVs and Navy SEAL forces. The projected cost for twelve submarines of this class was $33.6 billion, but after the Cold War, construction was stopped at three boats. Each boat is powered by a single S6W nuclear reactor, delivering 45,000 hp to a low-noise pump-jet.Īs a result of their advanced design, however, Seawolf submarines were much more expensive.
The class uses the more advanced ARCI Modified AN/BSY-2 combat system, which includes a new, larger spherical sonar array, a wide aperture array (WAA), and a new towed-array sonar. The boats also have extensive equipment to allow for littoral, or shallow water, operations. As in all nuclear submarines, the load out of equipment, weapons and crew affects available excess buoyancy and thus operational parameters. The boats are able to carry up to 50 UGM-109 Tomahawk cruise missiles for attacking land and sea surface targets. Ĭompared to previous Los Angeles class submarines, Seawolf submarines are larger, faster, and significantly quieter they also carry more weapons and have twice as many torpedo tubes, for a total of 8. These figures are consistent with their original design parameters and not unlikely. The exact diving depth of this class of boats is classified most reputable sources vary from 1,600–2,000 feet as a likely test depth, and from 2,400–3,200 feet for collapse depth. Seawolf class hulls are constructed from HY-100 steel, which is stronger than the HY-80 steel employed in previous classes, in order to withstand water pressure at greater depths. The Seawolf design was intended to combat the threat of large numbers of advanced Soviet ballistic missile submarines such as the Typhoon class and attack submarines such as the Akula class in a deep ocean environment. This, in turn, led to the design of the smaller Virginia class. The end of the Cold War and budget constraints led to the cancellation in 1995 of any further additions to the fleet, leaving the Seawolf class limited to just three boats.
At one time, an intended fleet of 29 submarines was to be built over a ten-year period, later reduced to twelve submarines. The class was the intended successor to the Los Angeles class. The Seawolf-class is a class of nuclear-powered fast attack submarines ( SSN) in service with the United States Navy. 8 × 660mm torpedo tubes (50 Tomahawk cruise missile/Harpoon/Mk-48 torpedo)
