RESTON, Va., Nov. 18, 2009 -- Northrop Grumman Corporation (NYSE:NOC) has been awarded a follow-on contract for wide-ranging maintenance support to the U.S. Department of Defense's Web-based occupational and environmental health information system that will enhance the collection and evaluation of industrial hygiene and environmental health data in the workplaces of military and civilian defense personnel.

The Defense Occupational and Environmental Health Readiness System (DOEHRS) was created to support the collection, storage and analysis of information regarding occupational exposures, workplace environmental monitoring, personal protective equipment usage, work practices and employee health-hazard educational data.

Northrop Grumman's Information Systems sector will conduct maintenance services to ensure the Web, mobile, theater and data warehouse capabilities of DOEHRS are available to the U.S. Department of Defense Military Health System user community. This support will include production management, testing, documentation, security maintenance and testing, and help desk services for DOEHRS applications.

In addition, Northrop Grumman will provide technical and analytical expertise for the acquisition of hardware and software to support DOEHRS. The company will also conduct software maintenance and troubleshooting for application and database servers.

"DOEHRS is a critical tool for Military Health System personnel in identifying workplace hazards and potential health risks and providing timely information and protective measures to health care providers and military personnel for better informed medical diagnosis and treatment decisions," said Dave Nastase, vice president of Advanced Public Services for Northrop Grumman's Civil Systems division. "Northrop Grumman will continue to provide unparalleled continuity of service and commitment to technical quality to the defense community through this world-class occupational exposure system."

Northrop Grumman was awarded the DOEHRS development contract in 2002, and the DOEHRS maintenance contract in 2005. The follow-on contract is valued at $14.5 million over one base year and two, one-year option periods.

Work on the contract will be conducted in Herndon, Va.
