Your search engine would have revealed it is a 688 attack submarine.
I looked it up.
WikipediaThe Los Angeles class boats are nuclear-powered fast attack submarines (SSN) in service with the United States Navy. The submarines are also known as the 688 class (pronounced "Six-Eighty-Eight"), after the hull number of lead vessel USS Los Angeles (SSN-688). They represent two generations and close to half a century of the Navy's attack submarine fleet. As of 2018, 35 of the class are still in commission and 27 are retired from service. Of the 27 retired boats, 12 were laid up half way (about 20 years or less) through their projected lifespans, and another five also laid up early (20–25 years), due to their midlife reactor refueling being cancelled, and one was lost due to a fire.
Seven have been scrapped and two are being converted to moored training ships. A further four boats were proposed by the Navy, but later cancelled.
The class has more active nuclear submarines than any other class in the world. Submarines of this class are named after American towns and cities, such as Albany, New York; Los Angeles, California; and Tucson, Arizona, with the exception of USS Hyman G. Rickover, named after a US Navy Admiral. This was a change from long-standing tradition of naming attack submarines after marine animals, such as USS Seawolf or USS Shark.
