Description: Features: The SSN-688 is a nuclear-powered attack submarine designed to deal with both enemy submarines and surface combatants. It has a largely cylindrical pressure hull in place of the Albacore hull adopted by the Permit and Sturgeon classes. The pressure hull itself is thinner than the earlier designs, reducing safe diving depths. The submarine structure itself is a single-hull design in which the pressure hull also forms the outer skin of the hull. The only exception to this is the bow and stern where an outer hull sheaths the sonar domes and ballast tanks. These design features all relate to a concentration on speed over other characteristics. The primary weapon systems of the class are the Mark 48 torpedo, the UGM-84 Harpoon anti-ship missile and the UGM-109 Tomahawk cruise missile. The first 12 units of the SSN-688 class were equipped with the Mark 113 Mod 10 fire control system and could fire the UUM-44A SUBROC anti-submarine rocket, but not the Tomahawk cruise missile. All boats built since SSN-700 have the Mark 117 fire control system, and can fire Tomahawk, but not the SUBROC. The Los Angeles class is powered by an S6G reactor derived from the D2G powerplant of the CGN-25 class cruisers. All boats are equipped with a Fairbanks-Morse 38D8Q diesel-powered electric generator and batteries for emergency operations. Background: The maximum speeds of American attack submarines had been dropping through the earlier SSN-594 Permit and SSN-637 Sturgeon programs since the roles adopted by those boats placed greater emphasis on silence than on speed. The SSN-688 was conceived as a limited production special role boat in which these priorities would be reversed. The new class also took advantage of technological advances in undersea detection and weapons development. These improvements included an improved long-range detection and tracking sonar, improved torpedo fire control, a dual inertial navigation system, improved noise reduction and a rubber sonar dome in the bow. In 1969, the US Navy awarded the SSN-688 class design contract to Newport News Shipbuilding & Drydock. This was the first time that Newport News served as the design yard for a submarine and the first time that General Dynamics, Electric Boat Division, or a naval shipyard did not perform this role. The first SSN-688 contracts were issued in January 1971. Seven went to General Dynamics' Electric Boat Division and five to Newport News. The early construction history was marred by repeated cost overruns and a running dispute between the US Navy and Electric Boat.
