LOS ANGELES, April 17, 2003 -- Northrop Grumman Corporation (NYSE:NOC) announced today that it has successfully completed the stand up of the defense-related operations acquired in December 2002 from TRW Inc. Two new operating sectors were created from that acquisition -- Mission Systems and Space Technology.

Both sectors' policies and operating procedures now comply with those of Northrop Grumman. These include a wide range of policies and procedures, including financial reporting, program oversight and risk management, human resources practices and access to the company's electronic network, among others.

The Mission Systems and Space Technology sectors will continue to work closely with Northrop Grumman's five other operating sectors and corporate staff to identify and leverage company-wide capabilities. The new sectors are led by Don Winter, corporate vice president and president of Mission Systems, and Wes Bush, corporate vice president and president of Space Technology.

"Today marks another key milestone in our business integration efforts, providing further testimony to our ability to swiftly and efficiently integrate acquired companies," said Ronald D. Sugar, Northrop Grumman's chief executive officer and president. "This core competency allows us to reap the benefits of diverse programs and capabilities while honoring legacy company traditions and best practices along the way. The stand up of the Mission Systems and Space Technology sectors was accomplished ahead of schedule and without any major issues."

The company also stated that the migration of all TRW corporate functions is also on schedule and is expected to be completed by the end of the year.

The acquisition of TRW was a capstone event in a decade-long series of mergers and acquisitions. Since 1994, Northrop Grumman has acquired 16 companies, growing from about $5 billion in annual revenues to an estimated $25 billion to $26 billion for 2003, and from about 30,000 employees to nearly 120,000.
