Northrop was selected along with a number of other tech vendors under the GSA's Alliant program, through which the government plans to modernize IT infrastructures across numerous agencies and departments.
Northrop and other vendors will compete for specific task orders under the program.
"Northrop Grumman brings experience in providing comprehensive information technology solutions that support the complete enterprise life-cycle for all levels of the federal government," said Dave Ryan, VP for business development at Northrop Grumman's Information Systems sector, in a statement.
Other contractors previously selected to bid for Alliant work include IBM, Accenture, Computer Sciences Corp., SAIC, and Unisys.
Northrop said it plans to compete for Alliant work related to computer network support, software engineering, and other IT services for civilian agencies and the Department of Defense. Northrop Grumman is the lead contractor for a team that includes 50 large and small businesses.
"We will provide the best value to help the federal government achieve their mission application needs," said Ryan.
Alliant replaces the GSA's Millennia and Answer contracts.
The program hasn't been without controversy. In 2007, a handful of outsourcers not selected to participate sued the federal government, claiming the bidding process was unfair. The lawsuit led to delays in handing out work previously authorized under the Alliant program.
Northrop shares were off 0.36% to $47.71 in early trading Wednesday.
