Northrop Grumman Corporation has been awarded a contract from the U.S. Navy for maintenance work on the nuclear-powered submarine USS Oklahoma City (SSN 723). Northrop Grumman's Newport News sector is the prime contractor for the work, which will include inspection and repair of the submarine's hull, sail, tanks and torpedo systems, as well as modifications to engine room equipment. The contract is valued at approximately $15m and is a modification to a contract awarded in 2004 for initial planning work. The total estimated value of that contract, including the planning and execution, is approximately $21.5m.
The ship arrived at the Newport News sector on April 10 for a performance period to last approximately two months. Approximately 300 employees will work on the project.
As one of only two U.S. shipyards capable of building nuclear-powered submarines, Northrop Grumman Newport News has built 25 of the Navy's Los Angeles-class submarines in use today, including the
USS Oklahoma City (SSN 723). Oklahoma City was launched in 1985 and delivered to the Navy in 1988. At 360 ft. in length, it can travel in excess of 20 knots.
