WOODLAND HILLS, Calif., Dec. 2, 2010 -- Northrop Grumman Corporation's (NYSE:NOC) Navigation Systems Division has achieved the International Organization for Standardization (ISO) 14001 certification, demonstrating that its environmental management system (EMS) meets rigorous international standards for minimizing the company's impact on the environment.

Northrop Grumman Navigation Systems Division sites in Woodland Hills, Calif., Norfolk, Va., and Salt Lake City achieved the certification by planning and implementing a robust EMS which was independently audited by Det Norske Veritas (DNV), a global provider of accredited management system certification. DNV's third party audit reviewed all aspects of the Northrop Grumman EMS relating to the ISO 14001 standard.

ISO is a non-governmental developer of world standards for business, government and society. The ISO 14001 certification requires an organization to manage, measure, improve and communicate its environmental program in a systematic way. Only those companies with excellent environmental programs qualify for this globally recognized certification.

One of the primary requirements for certification is to have a comprehensive list of environmental aspects associated with business operations and identify those that can cause the most significant impacts to the environment. The key commitments of the company's environmental policy include compliance with applicable environmental laws and regulations, continual improvement in minimizing environmental impact of operations and products, and motivation of employees to take personal accountability for protecting the environment and creating a safe and healthy workplace.

"Achieving ISO 14001 certification demonstrates Northrop Grumman's commitment to running an environmentally friendly business," said Liz Iversen, sector vice president and general manager of Northrop Grumman's Navigation Systems Division.
