To Provide First And Second Stages For Air Launch Vehicle

ATK has received a contract from Orbital Sciences Corporation to provide first and second stage propulsion for the Air Launch Vehicle (ALV) that Orbital is designing and building for Stratolaunch Systems Corporation as part of a revolutionary air-launched space transportation system. The contract from Orbital includes the design, development and flight hardware for initial Stratolaunch missions. 

"ATK is pleased to receive this award for the development and production of first and second stage propulsion for the Stratolaunch ALV," said Blake Larson, president of ATK Aerospace Group. "Our innovative propulsion concept combines both proven and state-of-the-art technologies that will provide a high-performing, cost-effective solution for the ALV."

This new work expands ATK's already strong partnership with Orbital, dating back to the development of Orbital's original air-launched vehicle, Pegasus, which also uses ATK solid rocket motors for stage propulsion.

"Our design solution for the ALV will take full advantage of ATK's experience with large diameter solid rocket motors, like those built for the Space Shuttle and for the Titan IVB launch vehicle.  The stages for ALV will also use high-strength, low-weight graphite composite cases, advanced propellants, and heritage materials from ATK's extensive line of commercial solid rocket motors," said Scott Lehr, vice president and general manager of ATK's Defense and Commercial Division.

"Solid rocket motors use stable propellants and have proven highly reliable in a wide variety of systems. They are highly engineered systems that are designed for simplified operations, and minimize ground support infrastructure requirements," Lehr added.
