Computer Sciences Corp. (CSC) of Falls Church, Va., was selected by the U.S. National Oceanic and Atmospheric Administration (NOAA) to develop a computing system to support environmental modeling under a four-year contract worth as much as $317 million, CSC announced May 14.

Under the terms of the High Performance Computing System contract, CSC will provide the hardware needed to improve the accuracy of regional and global climate and weather forecasting models, a press release said. The indefinite-delivery, indefinite-quantity contract includes a four-year option and an additional one-year transition option. The first year of the program is funded at $49.3 million using money NOAA received under the American Recovery and Reinvestment Act of 2009, CSC said.

CSC unseated incumbent Raytheon Intelligence and Information Systems of Garland, Texas, for the contract.
