Company Establishes New Office to Coordinate Pursuit of U.S. Department Of Defense Rocket, Satellite, Sensor and Technical Services Business

Orbital Sciences Corporation (NYSE: ORB) today announced that Dr. Robert E. Lindberg has been named Senior Vice President for Defense Programs, a newly formed position that will provide strategic direction and coordination of the company's business development activities in the areas of military space systems, missiles defense systems, classified programs and defense-related technical services.

Dr. Lindberg is an Orbital veteran with more than 14 years of experience with the company, having served in senior-level positions in program and operating group management and in business development. His tenure with the company has been nearly evenly divided between the satellite and launch vehicle business units, Orbital's two largest product areas. Prior to joining Orbital, Dr. Lindberg spent 10 years at the Naval Research Laboratory, where he conducted and led research in advanced space technologies.

Mr. David W. Thompson, Orbital's Chairman and Chief Executive Officer, said, "With the increased national focus being placed on missile defense and military space systems by the Bush Administration, it is important that Orbital play a significant role in helping our country achieve these priorities. Orbital's wide array of satellite platforms, space launch vehicles, and missile defense targets, combined with our exemplary record of reliability and our commitment to affordability, should make the company a strong competitor for many of the programs now being initiated by the U.S. Department of Defense."

Mr. Thompson added, "Dr. Lindberg is exceptionally qualified for his new role in spearheading our business pursuits in the defense arena. With Bob's strong combination of hands-on management experience, top-notch credentials as an aerospace engineer, and proven experience as a businessman who understands the importance of developing profitable new opportunities for the company, Orbital is on the right path to achieving our strategic objectives in the space-related defense market."

Dr. Lindberg holds a B.S. degree in Physics from Worcester Polytechnic Institute, an M.S. in Engineering Physics from the University of Virginia and a doctorate in Mechanical Engineering from Columbia University.

Orbital develops and manufactures affordable space systems, including satellites, launch vehicles, sensors and electronics, and advanced systems. Orbital is also involved with satellite-based networks that provide wireless data communications and high-resolution Earth imagery to customers all around the world.
