Proposes Solid Rocket Technology For ULA Atlas V First Stage

ATK has proposed an American-made commercial solid rocket solution to the U.S. Air Force as a replacement for the RD-180 Russian-made, first-stage engine of United Launch Alliance's (ULA) Atlas V launch vehicle.

"ATK's solid rocket propulsion solution provides a cost-effective, reliable solution based on advanced technology," said Blake Larson, president of ATK's Aerospace Group. "I am confident our solution will meet the capabilities of the current RD-180 engine and provide added performance if required."

The development of new technologies has led to innovative design improvement with solid rocket motors, resulting in higher performance and increased reliability and affordability. Over the past seven years, ATK has incorporated those new technologies in the development of six new solid rocket motors – some developed in less than two years.

"By combining our extensive experience with new technologies, we have provided commercial customers with low-cost solutions that progressed from design to flight qualification within months," said Larson. "Using a similar approach, ATK's propulsion solution will provide the U.S. Air Force with an RD-180 replacement rapidly and at a highly competitive cost."

Solid rocket motors are optimal for first-stage performance as they provide high lift-off thrust, allowing for more payload margin. They also require less ground and launch infrastructure, resulting in fewer launch scrubs.

Due to unmatched reliability, solid propulsion is used in every stage of America's strategic defense arsenal. New solid rocket motor technology has the capability to provide a smooth lift for payloads, which is especially important when launching critical payloads, sensitive satellites and crews.

This technology has resulted in decades of successful launches within the government and commercial industries. ATK has provided more than 1,900 commercial and more than 14,000 government solid rocket motors and integrated stages, all domestically built.

Manufacturing and testing of ATK's solution for the RD-180 replacement will take place within the United States using tooling and infrastructure already in place across the country.

"We recognize and congratulate the Air Force and ULA on their tremendous launch record," said Larson. "We are pleased to offer this solution to provide low-cost assured access for current and future National Security Space launch requirements."
