ATK has won a contract from Orbital Sciences Corp. to provide the propulsion system for an air-launched space rocket.
ATK will design, develop and provide the flight hardware of the first and second stage propulsion for Orbital’s air launch vehicle for Alabama-based Stratolaunch, ATK announced Tuesday.
“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,” said Scott Lehr, vice president and general manager of ATK’s defense and commercial division.
According to Lehr, solid rocket motors have stable propellants intended to simplify operations and minimize ground support requirements.
“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 Lehr.
ATK has produced solid rocket motors for launch vehicles such as the Delta II, Delta IV and Orbital’s Pegasus, Taurus, Minotaur and Antares.
