Northrop Grumman said the cost plus-fixed-fee contract is for Los Angeles-class, Seawolf-class, Virginia-class and Ohio-class submarines, special mission submersible interfaces, submarine support facilities and related programs.
The company's Shipbuilding sector in Newport News, Va., is the prime contractor and will provide engineering, design, configuration management, integrated logistic support, database management and modernization support.
Work is expected to begin immediately and continue into next year, the company said.
"We are excited to continue providing key engineering and technical services for a wide range of submarines for the U.S. Navy," said Becky Stewart, vice president, Submarine programs and Fleet Support for Northrop Grumman Shipbuilding. "Our shipbuilders are committed to delivering and supporting the submarines that play vital roles in America's defense."
Newport News is one of two U.S. shipyards capable of building nuclear-powered submarines.
