The Los Angeles class (also known as the 688-class) is a class of nuclear-powered fast attack submarines (SSN) in service with the United States Navy. They represent two generations and close to half a century of the U.S. Navy's attack submarine fleet. The class has more operating nuclear submarines than any other in the world, and all submarines of this class are named after American cities and a few towns (e.g. Key West, Florida, and Greeneville, Tennessee).

In 1982 after building 31 ships, the class underwent a minor redesign, the following 8 that made up the second «flight» of subs had 12 new vertical launch tubes that could fire tomahawk missiles. The last 23 saw a significant upgrade with the 688i improvement program. These boats are quieter, with more advanced electronics, sensors, and noise reduction technology. Externally they can be recognized quickly as their retractable diving planes were placed at their bows rather than on their sails.
