Orbital Marks 25th Anniversary Of Company's Founding
-- Company Thanks Customers and Employees for Their Contributions Over Last 25 Years --
-- Orbital Tallies Over 770 Rockets and Satellites Built or Under Contract Since 1982 --

Dulles, VA 2 April 2007) – Orbital Sciences Corporation (NYSE: ORB) celebrated the company’s first quarter-century in the space business today as it completed 25 years of operations since the enterprise’s founding on April 2, 1982. At anniversary events starting at the company’s Dulles, Virginia headquarters and continuing later this week at other sites, Orbital executives thanked its employees and customers for making possible the company’s successes to date, and for providing exciting opportunities for future achievements.

  "Reflecting on our first 25 years in business, Orbital’s Board of Directors and senior management team are deeply grateful to our customers for their willingness to trust a new enterprise to carry out many of their critical space projects. We also want to offer our heartfelt thanks to the company’s employees and their families, whose creativity, dedication and sacrifices allowed us to fulfill our customer commitments while also building a strong foundation for future growth," said Mr. David W. Thompson, Orbital’s Chairman and Chief Executive Officer.

 From three cofounders and no revenues in 1982, Orbital has grown to over 3,000 people and almost $900 million in annual revenues expected in 2007. During the last 25 years, the company has generated cumulative revenues of approximately $8.7 billion, providing over 45,000 person-years of high-technology employment for its workforce.

 Since its founding in 1982, the company has been among the space industry’s most active developers and manufacturers of launch vehicles and space systems. Its operational accomplishments during the past quarter-century have involved selling, designing and building 772 rockets and space systems. This total includes 583 launch vehicles, missiles, satellites and other space systems completed and delivered to date, plus 189 satellites, rockets and related systems currently under firm contracts with customer deliveries scheduled from 2007 to 2012.

 Technology Advances and Product Innovations

Orbital pioneered several significant space industry innovations during the last 25 years, including these important milestones: 

  • Development of the world’s first privately-funded space launch vehicle, culminating in the Pegasus rocket’s inaugural flight in 1990;
  • Creation of the industry’s first modern microsatellites, involving the design, manufacturing and operation of more than 20 100-kilogram (or smaller) spacecraft for various customers and applications in the 1985-1993 period;
  • Design, production and launch of the first commercial low-orbit communications satellites in 1995, leading to full deployment of a 35-satellite global network during 1997-1999;
  • Modification of the first U.S. solid fuel ICBM’s to be used as space launch vehicles and special-purpose R&D platforms, with launches beginning in 2000;
  • Introduction of the industry’s leading small geosynchronous communications and broadcasting satellites in the late 1990’s and early 2000’s; and
  • Substantial contributions to the advancements of critical technologies over the last five years, in areas such as missile defense programs, ramjet and scramjet propulsion, autonomous space rendezvous, responsive space operations, and satellite communications and imaging systems.

Satellite and Launch Vehicle Manufacturing Activity

Orbital’s experience over its first quarter-century includes design, development and manufacturing of 122 satellites and 43 major space systems for commercial, scientific and national defense customers, with details as follows: 

  • 64 commercial communications, broadcasting and imaging satellites for operators in North America, South America, Europe, Asia and Australia;
  • 24 space and Earth science spacecraft for government agencies, universities and research laboratories;
  • 34 R&D, technology demonstration and operational satellites for national defense and civil government users; and
  • 43 satellite subsystems and attached space payloads for government and commercial customers. 

During that same 25-year period, the company also designed and built, or now has under development and production, 607 launch vehicles and missile systems, comprising four general categories of rockets:

  • 78 space launch vehicles and related systems for unmanned and manned space missions, including the Pegasus, Taurus and Minotaur space launchers and NASA’s new Orion crew exploration vehicle launch escape system;
  • 75 interceptor launch vehicles for missile defense systems, consisting of boost vehicles for both the Missile Defense Agency’s (MDA) Ground-based Midcourse Defense and Kinetic Energy Interceptor programs;
  • 118 major target vehicles for missile defense testing and related experimental applications, covering a wide array of short-, medium- and long-range targets and countermeasure systems; and
  • 336 smaller missile systems and scientific sounding rockets, including low-altitude supersonic ramjet-powered targets and various high-altitude research vehicles.

Orbital’s constant focus on product safety and dependability has resulted in a 96.6% reliability record on the 320 major space missions (those with total value in excess of $5 million) it has conducted over the last 25 years, increasing to 98.7% on 153 major missions carried out in the last 10 years and 100% on 65 major missions in the last five years.

Looking Ahead 

Today, the company’s space systems and launch vehicles are used by our customers in many mission-critical governmental and commercial applications, including the following:

  • Over a dozen company-supplied MDA long-range missile interceptor boosters are currently on alert status – increasing to 24 interceptors by this fall -- in Alaska and California, vital elements of the United States’ first-ever national defense system protecting 300 million Americans from missile attack;
  • 55 company-built satellites are currently in operation, including 40 commercial communications spacecraft providing broadcast, voice and data services to millions of customers around the globe;
  • During the 2007-2009 interval, more than a dozen Pegasus, Taurus and Minotaur rockets are scheduled to launch NASA, U.S. Air Force, MDA and Defense Advanced Research Projects Agency satellites and other payloads into space, in support of important scientific and defense missions;
  • By mid-2007, the Orbital-developed Dawn deep-space exploration spacecraft will be on its way to explore two of the solar system’s largest main-belt asteroids, beginning an eight-year, multi-billion mile mission of scientific discovery;
  • Some 50 "Coyote" supersonic ramjet targets, already delivered or now being built by the company, are helping the U.S. Navy test and perfect defense systems for aircraft carriers and other naval vessels from sea-skimming anti-ship missiles; and
  • Beginning next year, launch escape systems under development by the company for NASA’s Orion human space exploration vehicle will begin test flights, contributing to enhanced safety for our astronauts for decades to come.

"As proud as I am of what Orbital’s people have achieved so far, I am convinced that the company’s greatest accomplishments are still to come. With the continued confidence of our customers and commitment of our employees, our adventure is just beginning," Mr. Thompson concluded.
