Science Applications International Corp. (SAIC) of McLean, Va., won a NASA information technology contract potentially worth more than $300 million over five years, the U.S. space agency announced Oct. 28.

Under the Enterprise Applications Services Technologies Contract, SAIC will provide all services necessary to operate and maintain NASA’s set of integrated enterprise application systems supporting all 10 of the agency’s regional field centers, NASA headquarters in Washington, and the NASA Shared Services Center in Bay St. Louis, Miss.

The base award of the two-year, firm-price/fixed-price portion of the contract is $85.6 million; options and work contemplated under an indefinite-delivery, indefinite-quantity contract provisions could bring the total value to $321.2 million, NASA said.

The contract, which begins Feb. 1 following a 90-day phase-in period, will be managed by NASA’s Marshall Space Flight Center in Huntsville, Ala.
