Los Angeles-class Nuclear Attack Submarine

The Los Angeles-class, sometimes called the LA-class or the 688-class, is a class of nuclear-powered fast attack submarines that forms the backbone of the U.S. Navy's submarine force, with 68 submarines of this class being completed. As of late 2012, fifty-one of the class are still in commission and seventeen retired from service, mostly due to their mid-life reactor refuellings being cancelled. A further four boats were proposed by the Navy, but later cancelled. The US also offered the Los Angeles-class to Canada in the late 1980s as a competitor to the British Trafalgar and French Rubis-class

The Los Angeles-class contains more nuclear submarines than any other class in the world. The class was preceded by the Sturgeon-class and followed by the Seawolf and Virginia-classes. Except for USS Hyman G. Rickover (SSN-709), all submarines of this class are named after American cities and a few towns (e.g. Key West, Florida and Greeneville, Tennessee). This system of naming broke a long-standing tradition in the U.S. Navy of naming attack submarines for creatures of the ocean (e.g. USS Nautilus (SSN-571)).

The final twenty-three boats of the Los Angeles-class were designed and built to be quieter than their predecessors and also to carry more-advanced sensor and weapons systems. These advanced boats were also designed for operating beneath the polar ice cap. Their diving planes were placed at their bows rather than on their sails, and they have stronger sails for penetrating thick ice.
