ATK was launched as an independent company in 1990, when Honeywell spun off its defense businesses to shareholders. The former Honeywell businesses had supplied defense products and systems to the U.S. and its allies for 50 years, including the first electronic autopilot that enabled B-17 aircraft to accomplish pinpoint bombing missions during World War II.

ATK expanded into the aerospace market with the acquisitions of Hercules Aerospace Company in 1995 and Thiokol Propulsion in 2001, which transformed the company into the world’s largest supplier of solid propellant rocket motors and a leading provider of high-performance composite structures.
