USS Los Angeles (SSN 688) nuclear submarine

Last crawled date: 1 year, 1 month ago

Updated 5/24/12 upgraded propeller to LA Class from 1980's 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 45 submarines on active-duty (and 17 retired), this class has more boats than any other nuclear powered submarine 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), submarines of this class are named after U.S. cities, breaking a long-standing Navy tradition of naming attack submarines after sea creatures. 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. #688 #cold_war #fast_attack #LA_class #nuclear #SSN #Sub #submarine #us_navy
