Function: Nuclear powered Fast Attack submarine.
History: Deployed on November 13, 1976, the Los Angeles (SSN688) fast attack submarine marked a technological leap forward in submarine design. Built from the screw forward as a dedicated antisubmarine warfare (ASW) platform, the Los Angeles class submarines were designed to guard American Carrier Battle Groups by hunting Soviet submarines and anti-surface warfare (ASUW) capitol ships like the Kirov class BCGN. The Los Angeles submarines were faster, quieter, carried more sophisticated sensors and possessed better weapons than any other submarine in existence. In addition to their primary function as offensive ASW weapons the 688 boats perform a number of additional duties to include sub surface precision land attack strikes (using tube launched Tomahawk cruise missiles), intelligence gathering, mine warfare, and special operations support (SEAL deployment and recovery). In fact, their performance was so revolutionary that beginning with USS Providence (SSN719) the hull was lengthened to accommodate 12 vertical launch system (VLS) tubes to allow the submarines to launch Tomahawk land attack cruise missiles. Nearing the end of their 30-year lives, the Los Angeles class submarines are slowly being replaced by the Improved Los Angeles (San Juan SSN751), the Seawolf (SSN21) and ultimately by the Virginia class (SSN774).
