Lockheed Martin Corporation today announced that Joanne M. Maguire will succeed G. Thomas Marsh as executive vice president of Lockheed Martin Space Systems when Marsh retires July 1.

Reporting directly to Chairman, President and CEO Robert J. Stevens, Maguire, 52, will be responsible for all business operations and activities of the corporation's $7 billion Space Systems unit, a world leader in the design, production and integration of launch vehicles and systems, spacecraft for telecommunications, remote sensing and space science, and missile systems for defensive and strategic missions. Space Systems employs some 18,000 people located primarily in Sunnyvale, Calif.; Denver, Colo.; New Orleans, La.; San Diego and Vandenberg Air Force Base, Calif.; Harlingen, Texas; Newtown, Pa.; McLean, Va.; and Cocoa Beach, Fla.

Since 2003, Maguire has served as Marsh's deputy and has been involved in all aspects of managing the business. She is also an officer of the Corporation. "Joanne is a highly capable and effective leader who brings vast experience to her new position," Stevens said. "Her close working relationship with Tom Marsh over the past few years has provided superb preparation for her new role and I am confident of a seamless transition."

Prior to joining Lockheed Martin, Maguire served as deputy to the chief executive of TRW Space & Electronics, the culmination of a 28-year career with TRW that included high-level leadership positions in the company's civil and military space divisions and in business development. She holds a bachelor's degree in electrical engineering from Michigan State University and a master's in system engineering from University of California at Los Angeles.

Marsh, 62, has led Lockheed Martin Space Systems since June 2003 and, prior to that, served as president of the company's former Missiles and Space Operations. During his career, Marsh made significant contributions to the nation's space program, which were recognized by NASA with two Public Service Awards. He is also a fellow of the American Astronomical Society, a fellow of the American Institute of Aeronautics and Astronautics (AIAA) and a member of the Institute of Electrical and Electronics Engineers (IEEE).

"We are deeply appreciative of Tom Marsh's leadership of our Space Systems organization since 2003 and his countless other contributions to the Corporation since he joined us in 1969," said Stevens. "His technical knowledge, his understanding of the business, and his upbeat and positive management style have benefited our company, our customers, and our employees and I want to extend my personal thanks to him for his outstanding service."

Headquartered in Bethesda, Md., Lockheed Martin employs about 135,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2005 sales of $37.2 billion.
