Precision Fuze Company
Alliant Techsystems Inc., commonly abbreviated ATK, is an aerospace and defense company with its headquarters in Arlington, Virginia in the United States. The company has more than 18,000 employees in 22 states, Puerto Rico and internationally, and 2010 revenues in excess of an estimated US$4.8 billion. The company was previously headquartered in Minneapolis, Minnesota.
ATK was formed in 1990 as a subsidiary of Honeywell Inc. as part of Honeywell's plan to exit the defense industry. Under the plan, Honeywell's defense businesses were transferred to ATK which was then spun off to Honeywell stockholders as a separate company.
In 1995 ATK entered the aerospace market with the acquisition of Hercules Inc. Aerospace division. Since then ATK has become a supplier of aerospace and defense products to the U.S. government and its allies, and to their contractors. ATK is also a supplier of ammunition and related accessories to law enforcement agencies and commercial customers.
In 2001, ATK acquired Thiokol, renaming it to ATK Launch Systems in 2006 (though it's 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 will be adapted to the Space Launch System. It also produces other solid-fuel propulsion systems, including the Star 48 upper stage. In addition, ATK manufactures the booster separation systems that release the motors away from the Shuttle orbiter and the main liquid fuel tank. Nearly every NASA planetary probe has used some form of propulsion from one of the company's divisions, and ATK also participated in the X-43A project. The company also produces the propulsion system used in the Trident D5 nuclear missile.
Alliant Techsystems, Edina, and Humbert CTTS SAS were awarded an approximately US$14 million contract to provide Speer 9mm GoldDot ammunition to the French Gendarmerie, French Customs, French Corrections and all 250,000 police officers in France. ATK expanded its workforce during the United States ammunition shortage.
Acquisitions and mergers 
Since 2000 ATK has grown as a result of both internal expansion and a series of acquisitions, including Thiokol propulsion, the ordnance business of Boeing and CCI/Speer, an ammunition manufacturer, and Federal Ammunition. In 2003 ATK purchased the General Applied Science Laboratory (GASL).
Major government contracts 
On March 12, 2012 ATK announced that it was awarded an Indefinite Delivery/Indefinite Quantity (IDIQ) agreement from the United States Department of Homeland Security (DHS) and U.S. Immigration and Customs Enforcement (ICE) for .40 caliber ammunition. This contract has a base of 12 months, includes four option years, and will have a maximum volume of 450 million rounds of hollow point bullets.

Liberty was not selected when the proposal awards were announced in August 2012.
