Orbital Selected for Major Missile Defense Rocket Program by Boeing

The GMD vehicle is a silo-launched three-stage rocket derived from Orbital's Pegasus and Taurus space boosters, the world's leading small satellite launchers.

ATK To Supply Propulsion System For GMD System
Minneapolis - March 8, 2002 ATK (Alliant Techsystems) said it is the solid propulsion supplier on a team led by Orbital Sciences selected by Boeing for a ground-based booster vehicle program in support of the U.S. Missile Defense Agency's Ground-based Midcourse Defense System (GMD). The value of ATK's work on the program could be approximately $300 million.

ATK Thiokol Propulsion will develop and produce solid propulsion motors for the Orbital GMD booster vehicles at its facilities in Promontory and Magna, Utah. The motors will be derived from the propulsion systems that fly on Orbital's Pegasus and Taurus launch vehicles, which are produced by ATK Thiokol Propulsion.

ATK is the world's leading supplier of solid propulsion systems for space, strategic, and tactical applications. Products include propulsion systems for NASA's Space Shuttle, unmanned space launch vehicles, strategic missiles, tactical missiles, and satellites.

Dulles - March 4, 2002
Orbital Sciences Corporation announced Monday that Boeing has selected the company for a contract, valued at $900 million or more over the next eight years, to develop, test and produce ground-based boost vehicles for America's ballistic missile defense system.

Part of the U.S. Defense Department/Missile Defense Agency's (MDA) Ground-based Midcourse Defense (GMD), the rocket-propelled boost vehicles will carry advanced exoatmospheric kill vehicles (EKVs) that are designed to locate, track and destroy long-range enemy missiles in flight, protecting all 50 States from future potential terrorist or rogue regime attacks.

Orbital's contract will include an approximate $400 million development and test phase, to be carried out from 2002 to 2006 and, if approved, a follow-on $535 million production, deployment and support phase, to be conducted from 2003 or 2004 through 2010.

According to current plans, a total of about 70 boost vehicles are to be built and delivered in the development and production phases of the baseline GMD program over the next seven years.

"The GMD boost vehicle award is one of the largest and most important contracts in Orbital's 20-year history," said Mr. David W. Thompson, Chairman and Chief Executive Officer.

"We strongly appreciate Boeing and MDA's confidence in our company's launch system capabilities and experience. We are totally committed to delivering reliable, on-time performance of all of our GMD program responsibilities," he added.

The company's GMD vehicle is a silo-launched three-stage rocket derived from Orbital's Pegasus and Taurus space boosters, the world's leading small satellite launchers.

Under its development and test contract with Boeing, Orbital will modify Pegasus and Taurus system designs and verify the resulting GMD boost vehicle's performance and operational features in a series of demonstration and test flights.

Orbital's Launch Systems Group (LSG) will carry out the GMD boost vehicle program, with its primary engineering and production staff in Chandler, Arizona. Other Orbital personnel in Dulles, Virginia, Huntsville, Alabama and Vandenberg Air Force Base, California, will participate in the program as well.

Major company subcontractors for the GMD boost include ATK Thiokol, Teledyne Brown Engineering, Mission Research Corporation and Electro Magnetic Applications.

"Our GMD boost vehicle work will build on Orbital's 20-year heritage of over 200 launch vehicles delivered or under contract for major U.S. Government and commercial customers," said Mr. Ronald J. Grabe, Executive Vice President and LSG General Manager.

"Boeing's contract further expands our company's role in America's missile defense programs and strengthens our already excellent prospects for growth in the suborbital vehicle product area," he added.

GMD has been in advanced development since 1998 and is based on technologies pioneered by MDA in the 1980's and 1990's. It is currently a research and development program incorporating extensive ground and flight tests to determine system performance against long-range ballistic missile targets.

There have been three successful intercepts in five flight tests since 1999, with approximately 19 more scheduled to take place over the next several years of the developmental test program.

While there has been no commitment to deploy the GMD technology, extensive testing efforts are scheduled to take place under operationally realistic conditions with the establishment of a new testbed in the central and northern Pacific Ocean areas, and a new testbed complex planned for Ft. Greely, Alaska beginning in 2004.

Boeing serves as MDA's overall prime contractor and systems integrator for GMD, supported by Raytheon (EKV and ground-based radar builder), Lockheed Martin (missile-warning satellite supplier) and TRW (battle management and communications system developer).
