Alliant Techsystems (ATK) was a significant player in the U.S. defense industrial base, providing propulsion systems for missiles and space launch vehicles, as well as ammunition and ordnance products. The company operated through multiple divisions serving military, commercial space, and civilian markets.
ATK was acquired by Orbital Sciences Corporation in 2018, forming Orbital ATK, which was subsequently acquired by Northrop Grumman in 2019.
ATK was formed through the merger of Alliant Techsystems Inc. and various aerospace divisions. The company grew through acquisitions and organic development to become a major supplier of solid rocket motors and propulsion systems for U.S. military and space programs throughout the late 20th and early 21st centuries.
