The Ohio class submarines serve the United States Navy as the virtually undetectable undersea launch platforms of intercontinental missiles. The Electric Boat Division of General Dynamics, based at Groton, Connecticut, has built 18 Ohio submarines, commissioned between 1981 and 1997. The submarines of the Pacific Fleet are based at Bangor, Washington, and those of the Atlantic Fleet at King's Bay, Georgia. The submarines spend 70 days at sea followed by 25 days in dock for overhaul.
Los Angeles Class Attack Submarines
Los Angeles-class (SSN688) submarines form the backbone of the U.S. Navy's nuclear-powered attack submarine fleet. Their primary missions are to hunt enemy submarines and surface ships, launch cruise-missile strikes on land-based targets and gather intelligence. The final 23 submarines of the 62-ship class are known as improved 688s. These are equipped with BSY-1 combat systems, as well as retractable bow planes and hardened sails to break through ice during Arctic operations.
