HII Awarded $188 Million US Navy Contract For Engineered Overhaul Of USS Columbus (SSN 762)
Huntington Ingalls Industries, Newport Information Shipbuilding Division, Newport Information, Virginia, was awarded a $188,908,033 cost-plus-fixed-fee modification to a beforehand awarded contract to proceed the efficiency of the restore, upkeep, upgrades, and modernization efforts on the united statesColumbus (SSN 762) engineered overhaul. USS Columbus (SSN-762) is a Los Angeles-class nuclear-powered fast-attack submarine and the second vessel of america Navy to be named for Columbus, Ohio. Work can be carried out in Newport Information, Virginia, and is predicted to be accomplished by December 2022. The Supervisor of Shipbuilding, Conversion and Restore, USN, Newport Information, Virginia is the contracting exercise.
The contract to construct her was awarded to the Electrical Boat Division of Normal Dynamics Company in Groton, Connecticut, on 21 March 1986 and her keel was laid down on 9 January 1991. She was launched on 1 August 1992 sponsored by Mrs. Margaret DeMars, spouse of Admiral Bruce DeMars, and commissioned on 24 July 1993. In September 1994, the submarine performed an interfleet switch to Pearl Harbor, Hawaii, and joined the U.S. Pacific, Fleet Submarine Pressure. Columbus deployed to the Western Pacific in late 1995 via early 1996 and performed a wide range of operations as a unit of the Seventh Fleet alongside the best way making port visits in Hong Kong, Subic Bay, Guam, and Yokosuka, Japan.
The Los Angeles class of submarines are nuclear-powered quick assault submarines (SSN) in service with america Navy. Also called the 688 class after the hull variety of lead vessel USS Los Angeles (SSN-688), 62 had been constructed from 1972 to 1996. As of 2020, 32 of the Los Angeles class stay in fee — greater than some other class on this planet — they usually account for greater than half of the U.S. Navy’s 53 quick assault submarines. Submarines of this class are named after American cities and cities, equivalent to Albany, New York; Los Angeles, California; and Tucson, Arizona, besides USS Hyman G. Rickover, named for the “father of the nuclear Navy.” This was a change from historically naming assault submarines after marine animals, equivalent to USS Seawolf or USS Shark.
Los Angeles-class submarines carry about 25 torpedo tube-launched weapons, in addition to Mark 67 and Mark 60 CAPTOR mines and had been designed to launch Tomahawk cruise missiles, and Harpoon missiles horizontally. The final 31 boats of this class even have 12 devoted vertical launching system tubes for launching Tomahawks. The Los Angeles class is powered by the Normal Electrical S6G pressurized water reactor. The new reactor coolant water heats water within the steam turbines, producing steam to energy the propulsion generators and ship service turbine turbines (SDGs), which generate the submarine’s electrical energy.An emergency propulsion motor on the shaft line or a retractable 325-hp secondary propulsion motor energy the submarine off the battery or diesel generator.
