Northrop Grumman Corp. said late Monday that a team of contractors it led has won a U.S. Army contract to develop an integrated air- and missile-defense battle command system.

The Los Angeles defense contractor said the new system will help troops make better battlefield decisions by integrating weapons, radar and sensor systems.

The system “takes care of the science of warfare, so the warfighter can focus on the art of warfare,” said Linda A. Mills, president of Northrop’s Information Systems sector.

The five-year contract for system design and development is valued at $577 million. The system is expected to be ready to be deployed by 2014.

The Northrop team includes Boeing, Lockheed Martin and 10 other companies..

Shares of Northrop, which announced that it plans to relocate to Washington D.D. by 2011, closed up 6 cents, or less than 1 percent, to $57.50 on the New York Stock Exchange.
