Five-year Total Value Could Exceed $80 Million

Minneapolis, Jan. 21, 2004 – ATK (Alliant Techsystems, NYSE: ATK) has signed an agreement with Lockheed Martin Commercial Space Systems, Newtown, Pa., to supply composite satellite components for the company’s A2100 communications satellite series. The five-year agreement has the potential to grow beyond $80 million of new business.

Work on the contract will be performed at ATK’s Composite Optics Inc. (COI) facilities in San Diego, Calif. and Salt Lake City, Utah.

James Gormican, president, COI, said the new agreement with Lockheed Martin is consistent with the company’s plan to organically grow the commercial sector of its business as the global market for commercial satellites rebounds in the coming years.

“We believe the satellite industry in general is making a turn for the better and ATK is solidly positioned to capture growth opportunities as the demand increases,” said Gormican.

The agreement calls for ATK to provide reflectors, satellite bus structures, standard antenna support structures, solar array substrates for power generation, as well as yokes and booms.

ATK is a $2.2 billion aerospace and defense company with strong positions in propulsion, composite structures, munitions, precision capabilities, and civil and sporting ammunition. The company, which is headquartered in Edina, Minn., employs approximately 12,600 people and has three business groups: Precision Systems, Aerospace, and Ammunition and Related Products.
