The Los Angeles class, sometimes called the LA-class or the 688-class, is a class of nuclear-powered fast attack submarines (SSN) that forms the backbone of the United States submarine fleet. With 46 submarines, this class has more boats than any other nuclear powered submarine class in the world.
The final 23 boats in the series, referred to as "688i" boats, are quieter than their predecessors and incorporate a more advanced combat system. These 688i boats are also designed for under-ice operations: their diving planes are on the bow rather than on the sail, and they have reinforced sails.
