LOS ANGELES, Dec. 13, 2002 (PRIMEZONE) -- Northrop Grumman Corporation (NYSE:NOC) today announced the appointments of two presidents to lead two new operating sectors created from the company's acquisition of TRW, Inc.

Donald C. Winter, 54, has been named a corporate vice president and president of the Northrop Grumman Mission Systems sector, formerly TRW Systems, where he served as president and chief executive officer. Northrop Grumman Mission Systems, with expected 2003 revenues of $3.9 billion, employs approximately 16,000 people and is headquartered in Reston, Va.

Timothy W. Hannemann, 59, has announced his intention to retire as president of the Northrop Grumman Space Technology sector, formerly TRW Space and Electronics, on Jan. 31, 2003. Effective Feb. 1, 2003, Wesley G. Bush, 41, will become corporate vice president and president of Northrop Grumman Space Technology. The sector, headquartered in Redondo Beach, Calif., has 2003 estimated revenues of $2.5 billion and employs approximately 8,600 employees.

"We are pleased to have such highly qualified executives to lead our two new operating sectors," said Kent Kresa, Northrop Grumman chairman and chief executive officer. "These two operating sectors join us with tremendous momentum, having won several large contracts in the past few months."

Commenting on Tim Hannemann, Northrop Grumman President and Chief Operating Officer Ronald D. Sugar said, "Over the past 33 years Tim has made remarkable contributions to TRW and is a recognized leader in the national security and civilian space industry. He has superbly positioned TRW's space and electronics business for continued growth and prosperity. We wish Tim well in his much-deserved retirement."

Sugar continued, "As a longtime colleague of both Don and Wes, I know firsthand of their outstanding capabilities. Don's proven leadership, strong technical background and excellent relationships with his customers will help our new Mission Systems sector continue to produce strong results."

Winter has served as president and CEO of TRW Systems since January 2000. A 28-year company veteran, Winter has also held senior systems engineering and program management positions for a variety of space system programs.

"Wes Bush has extensive management experience across a broad spectrum of the space business which makes him well qualified to lead our Space Technology sector as it begins work on some of its largest and most important new programs," Sugar added.

Bush most recently served as president and CEO of TRW Aeronautical Systems prior to its October 2002 sale to Goodrich Corporation. Previously, Bush spent 15 years at TRW Space & Electronics, where he had broad technology and operational experience in a series of management positions, leading to a vice president and deputy assignment. He also served as vice president and general manager of TRW's Telecommunications Programs Division, where he was responsible for developing and producing advanced satellite and terrestrial wireless communications.

Winter earned a Bachelor of Science degree (with highest distinction) in physics from the University of Rochester. He received a Master of Science degree and a doctorate in physics from the University of Michigan.
