====Atlas V====
{{Main|Atlas V}}
ATK entered the competition to replace the Russian-made rocket engine on the Atlas V rocket in September 2014. The Atlas V is used to launch most U.S. military satellites. ATK entered the competition in response to a request for proposals from the Air Force Space and Missile Defense Center issued in 2013 for the RD-180 rocket engine. ATK already supplies rocket engines used in heavier version of the Atlas V. ATK says that solid rocket motors are more reliable and deliver more thrust. ATK said, "Solid rocket motors are optimal for first-stage performance as they provide high lift-off thrust, allowing for more payload margin. They also require less ground and launch infrastructure, resulting in fewer launch scrubs."<ref>{{cite web|url=http://defensesystems.com/articles/2014/10/01/atk-to-compete-to-replace-russian-rocket-engine.aspx|title=ATK enters competition to replace Russian rocket engine -- Defense Systems|access-date=June 12, 2015}}</ref> The RD-180 engines use kerosene for fuel. The request from the Air Force occurred due to concerns about whether the RD-180 would be available in the future due to increasing tensions with Russia.<ref>{{cite web|url=http://www.spacenews.com/article/military-space/41966atk-urges-air-force-to-consider-solids-as-it-weighs-rd-180-replacement|archive-url=https://archive.today/20141006194948/http://www.spacenews.com/article/military-space/41966atk-urges-air-force-to-consider-solids-as-it-weighs-rd-180-replacement|url-status=dead|archive-date=October 6, 2014|title=ATK Urges Air Force To Consider Solids as It Weighs RD-180 Replacement|work=SpaceNews.com|access-date=June 12, 2015}}</ref>

====Lake City Army Ammunition Plant====
In 2012, ATK was selected by the [[United States Army]] to continue operating and maintaining the [[Lake City Army Ammunition Plant]] (LCAAP) for an additional seven to ten years. The LCAAP is a federally owned facility in Independence, Missouri. It was built by [[Remington Arms]] in 1941 to manufacture and test small-caliber ammunition for the army. As of July 2007, the plant produced about 1.5 billion rounds of ammunition per year. The LCAAP still tests ammunition and is the largest producer of small-arms ammunition for the U.S. military. ATK has operated the LCAAP since April 2001.<ref name="GS">"[http://www.globalsecurity.org/military/facility/aap-lakecity.htm Lake City Army Ammunition Plant]".

''[[USA Today]]''. 23 July 2007.</ref>

The United States Army and ATK opened a renovated ammunition production facility at the LCAAP in December 2014. The renovations improved efficiency and quality control. The Army and ATK invested $11 million to modernize "Building 65" for the production of 20 millimeter ammunition. These large caliber rounds are usually fired from automatic cannons mounted on ground vehicles and aircraft. Building 65 housed 20 millimeter round production until 1997, when it was moved to Building 3. About 50 people are employed on this line.<ref name="20mm">{{cite news |last=Dornbrook |first=James |date=3 December 2014 |title=ATK, U.S. Army invest $11M in Independence ammo plant |url=http://www.bizjournals.com/kansascity/news/2014/12/03/atk-u-s-army-invest-11m-in-independence-ammo-plant.html |newspaper=Kansas City Business Journal}}</ref>

====AN/AAR-47 Missile Approach Warning System====
The [[AN/AAR-47 Missile Approach Warning System]] (MWS) is used on slow moving aircraft such as helicopters and military transport aircraft to notify the pilot of threats and to trigger the aircraft's countermeasures systems. Its main users are the U.S. Army, Navy and Air Force, but is also operated by other countries. Originally developed by [[Loral Space & Communications]], it has been solely a product of ATK since 2002. The AN/AAR-47 passively detects missiles by their infrared signature, and uses algorithms to differentiate between incoming missiles and false alarms. Newer versions also have laser warning sensors and are capable of detecting a wider range of threats. After processing the nature of the threat, the system gives the pilot an audio and visual warning, and tells the direction of the incoming threat. It also sends a signal to the aircraft's infrared countermeasures system, which can then for example deploy flares. The development of the original AN/AAR-47(V)1 began in 1983 by Loral. ATK became a second production source in the mid 90s and eventually became the primary contractor. In 1998 ATK began production of the improved AN/AAR-47(V)2, which added laser warning functionality.<ref name="AAR1">{{cite web|url=http://www.globalsecurity.org/military/systems/aircraft/systems/an-aar-47.htm|title=AN/AAR-47 Missile Approach Warning System|author=John Pike|access-date=June 12, 2015}}</ref>

The [[M242 Bushmaster]] is a [[25 mm caliber|25 mm (25×137mm)]] [[chain gun|chain-fed]] [[autocannon]]. It is used extensively by the [[United States armed forces|United States]] and [[NATO]] forces in ground [[combat vehicle]]s and watercraft. Originally, the weapon was designed and manufactured by [[McDonnell Douglas]]. It is an externally powered, chain driven, single-barrel weapon which may be fired in semi-automatic, burst, or automatic modes. It is fed by a metallic link belt and has dual-feed capability. The term "chain gun" derives from the use of a [[roller chain]] that drives the bolt back and forth. The gun can destroy lightly armored vehicles and aerial targets, such as helicopters and slow-flying aircraft. It can also suppress enemy positions such as exposed troops, dug-in positions, and occupied built-up areas. The standard rate of fire is 200 [[cartridge (firearms)|rounds]] per minute. The weapon has an effective range of {{convert|3000|m|lk=on}}, depending on the type of ammunition used.

The [[Mk44 Bushmaster II]] is a [[30 mm caliber|30 mm]] [[chain gun]] also manufactured by ATK.

The XM813 Bushmaster, also produced by ATK Defense, is based on the Mk44 and is offered as an upgrade for [[M1126 infantry carrier vehicle|M1126 Stryker]] and [[M2 Bradley]].  Improvements include a one-inch longer barrel, integral mount to increase first round hit probability by up to 10 percent, and dual recoil system to enhance accuracy and cope with future hotter propellants.  It can have a next-round select, linkless feed system.  The 30&nbsp;mm chain gun can fire Mk310 Programmable [[Air burst|Air Burst]] Munition rounds to attack targets in defilade.  The [[United States Army Research, Development and Engineering Command]] helped enhance the XM813 mainly for safety and turret integration.  By changing five parts, the gun caliber can be increased to 40&nbsp;mm.  As of November 2013, the XM813 was being tested at [[Aberdeen Proving Ground]].<ref>{{cite web |url=http://www.dtic.mil/ndia/2012armaments/Wednesday14027hart.pdf |title=Archived copy |access-date=2013-12-08 |url-status=dead |archive-url=https://web.archive.org/web/20130719192202/http://www.dtic.mil/ndia/2012armaments/Wednesday14027hart.pdf |archive-date=July 19, 2013 |df=mdy-all }}</ref><ref>[http://www.armytimes.com/article/20131108/NEWS/311080016/ Bigger, badder Bushmaster cannon in the works] - Armytimes.com, 8 November 2013</ref>
