Alliant Techsystems Inc. (ATK) is an aerospace, defense, and sporting goods company with its headquarters in Arlington, Virginia, in the United States. The company operates in 22 states, Puerto Rico, and other countries. ATK had revenues of about US$4.4 billion in 2013.
ATK was launched as an independent company in 1990, when Honeywell Inc. 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.
Mergers and acquisitions
In 1995, ATK entered the aerospace market with the acquisition of the aerospace division of Hercules Inc. Since then ATK has become a supplier of aerospace and defense products to the U.S. government and its allies, and to their contractors.
In 2001, ATK acquired Thiokol, renaming it to ATK Launch Systems in 2006 (though it is still known within the industry by its original name). Thiokol was the sole manufacturer of the reusable Solid Rocket Motor used to launch the NASA Space Shuttle, which is being adapted for NASA’s Space Launch System.
Also in 2001, ATK entered the sporting and law enforcement ammunition market with the acquisition of the ammunition businesses of Blount International. This acquisition made ATK the nation's largest manufacturer of ammunition.
In 2009, ATK acquired Eagle Industries and in 2010 ATK acquired Blackhawk Industries Products Group Unlimited, LLC, diversifying into the security and law enforcement market.
In 2013, ATK acquired Caliber Company, the parent company of Savage Sports Corporation (Savage), one of the world's largest manufacturers of hunting rifles and shotguns. Later in 2013, ATK acquired Bushnell, an outdoor accessories company with 19 iconic brands that specialize in sports optics, hunting/camping accessories and performance eyewear.
