EL SEGUNDO, Calif., Nov. 20, 2003 (PRIMEZONE) -- Two business elements of Northrop Grumman Corporation's (NYSE:NOC) Integrated Systems sector have achieved ISO 9001:2000 certification, signifying that their common quality management system meets stringent industry requirements.

To be certified, companies must implement a quality management system encompassing the enterprise's activities, including staff training, meeting customer expectations, designing and developing products, purchasing materials and services, and delivering products and services.

"Certification increases our customers' confidence that systems, processes and controls are in place to ensure product conformity and continuous improvement in our operations," said Gary W. Ervin, sector vice president, Air Combat Systems. "We have always been committed to quality, and certification to the ISO 9001:2000 standard recognizes that our quality management system-and the employees who work with it every day-are the best in their class."

The ISO 9001:2000 standard, released in December 2000 as the successor to ISO 9000:1994, is an internationally recognized quality management system. The Air Combat Systems and Unmanned Systems elements of Northrop Grumman Integrated Systems were awarded the certification after a third-party audit by British Standards Institute Inc., a quality management systems registrar. The audit was conducted at Air Combat Systems sites in El Segundo and Palmdale, Calif., and New Town, N.D., and at the Unmanned Systems site in San Diego, Calif.

The audit verified the company's commitment to eight quality management principles: customer focus, leadership, involvement of people, process approach, system approach to management, continuous improvement, factual approach to decision-making and mutually beneficial supplier relationships.

Northrop Grumman Integrated Systems is a premier aerospace and defense systems integration enterprise. Headquartered in El Segundo, Calif., it designs, develops, produces and supports network-enabled integrated systems and subsystems for government and civil customers worldwide.
