As of April 2014, ATK had a three-year contract with [[Lockheed Martin|Lockheed]] to develop a warhead for the [[M270 Multiple Launch Rocket System|Guided Multiple Launch Rocket System]]. The contract includes engineering, manufacturing, and development. ATK's work will focus on system performance, warhead qualification, and producibility.<ref name="GMLRS">{{cite web|url=http://blog.executivebiz.com/2014/04/lockheed-to-start-atk-built-alternative-warhead-tests-with-soldiers-in-the-summer/#sthash.Q87m1cxj.dpuf|title=Lockheed to Start ATK-Built Alternative Warhead Tests With Soldiers in the Summer|work=ExecutiveBiz|date=April 17, 2014 |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>

====AGM-88E Advanced Anti-Radiation Guided Missile====
[[File:AGM-88E HARM p1230047.jpg|left|thumb|AGM-88E]]
The [[AGM-88 HARM|AGM-88E Advanced Anti-Radiation Guided Missile]] (AARGM) is an upgrade to the AGM-88 High-speed Anti-Radiation Missile (HARM). The AARGM is the result of cooperation between the United States and Italy. It is produced by ATK. In September 2013, ATK delivered the 100th AARGM to the U.S. Navy. It will be initially integrated onto the FA-18C/D, FA-18E/F, EA-18G, and Tornado ECR aircraft and later on the [[F-35 Lightning II|F-35]].<ref>{{cite web |url=https://www.reuters.com/article/2009/01/21/idUS152956+21-Jan-2009+PRN20090121 |title=ATK Awarded $55 Million Advanced Anti-Radiation Guided Missile Low Rate Initial Production... |publisher=Reuters |date=2009-01-21 |access-date=2011-07-13 |url-status=dead |archive-url=https://web.archive.org/web/20130623150446/https://www.reuters.com/article/2009/01/21/idUS152956%2B21-Jan-2009%2BPRN20090121 |archive-date=June 23, 2013 |df=mdy-all }}</ref> The AGM-88E development program was proceeded on schedule and did not exceed its budget.<ref name="AARGM1">{{cite press release|url=http://www.prnewswire.com/news-releases/atk-delivers-100th-advanced-anti-radiation-guided-missile-aargm-to-us-navy-224053301.html|title=ATK Delivers 100th Advanced Anti-Radiation Guided Missile (AARGM) to U.S. Navy|author=ATK|date=September 17, 2013|access-date=June 12, 2015}}</ref>

In August 2014, the [[United States Navy]] awarded a full-rate production contract to ATK to produce to AARGM. Under this contract ATK will also provide captive air training missiles for both the United States and Italy. This is the third contract for the AARGM won by ATK and it is worth $96.2 million.<ref>{{cite web|url=http://www.naval-technology.com/news/newsus-navy-awards-third-aargm-full-rate-production-contract-to-atk-4342417|title=US Navy awards third AARGM full-rate production contract to ATK|date=August 12, 2014 |access-date=June 12, 2015}}</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>

====Precision Guidance Kit====
{{Main|XM1156 Precision Guidance Kit}}
The Precision Guidance Kit (PGK) is a United States Army program to develop a [[precision guidance]] system for existing 155&nbsp;mm [[artillery shell]]s.<ref name="GLOBSEC">{{cite web|url=http://www.globalsecurity.org/military/systems/munitions/m1156.htm|title=XM1156 Precision Guidance Kit (PGK)|author=John Pike|access-date=June 12, 2015}}</ref> The prime contractor is Alliant Techsystems and the project team includes Interstate Electronics Corporation.<ref name="ATKPGK_01">{{Cite web|url=http://www.atk.com/capabilities_defense/cs_ms_w_gp_pgk.asp|title=ATK Precision Guidance Kit (PGK) - ATK}}</ref> In operation the PGK will screw into the nose of the [[projectile]] much like the existing [[fuze]]. However, as well as the fuzing function it will provide a [[Global Positioning System|GPS]] [[Missile guidance|guidance]] package and [[Flight control surfaces|control surface]]s to correct the flight of the shell.  This is analogous to the addition of a [[Joint Direct Attack Munition]] (JDAM) tail-kit to a dumb iron bomb, creating a [[precision guided munition]].  Production started in 2009.<ref name="DEFNEWS_01">{{Cite web|url=http://defensenews.com/story.php?F=2793630&C=america|archive-url=https://archive.today/20130121093542/http://defensenews.com/story.php?F=2793630&C=america|url-status=dead|archive-date=2013-01-21|title=ATK To Make Precision Artillery Shell - defensenews.com}}</ref>

====Bushmaster autocannons====

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.  It is a derivative of the [[25 mm caliber|25 mm]] M242 referenced above and uses 70% of the same parts as the M242. The Mk 44 Bushmaster II is the standard primary armament of the [[Bionix AFV|Bionix-II AFV]] currently in service with the [[Singapore Army]], the [[KTO Rosomak]] in [[Polish Army|Polish]] service as well as that of the [[CV90|CV90 AFV]]s in [[Finnish Army|Finnish]], [[Norwegian Army|Norwegian]] and [[Swiss Army|Swiss]] service. Some [[United States Navy]] vessels, such as the new [[San Antonio-class amphibious transport dock|''San Antonio''-class amphibious transport dock]] are armed with the Bushmaster II for surface threat defense.<ref>{{cite web |url=http://www.nwfdailynews.com/share/profiles/?slid=52836bbc-64ad-c2d4-9dae-291a895b67d1&plckController=PersonaBlog&plckScript=personaScript&plckElementId=personaDest&plckPersonaPage=BlogViewPost&plckPostId=Blog%3a52836bbc-64ad-c2d4-9dae-291a895b67d1Post%3a4d252120-6dcd-4132-b823-23038489868d&sid=sitelife.nwfdailynews.com |title=Air Force Cancels 30 mm Cannon Program for AC-130U Gunships - Inside the Air Force, 11 July 2008 |url-status=dead |archive-url=https://web.archive.org/web/20110928133016/http://www.nwfdailynews.com/share/profiles/?slid=52836bbc-64ad-c2d4-9dae-291a895b67d1&plckController=PersonaBlog&plckScript=personaScript&plckElementId=personaDest&plckPersonaPage=BlogViewPost&plckPostId=Blog%3A52836bbc-64ad-c2d4-9dae-291a895b67d1Post%3A4d252120-6dcd-4132-b823-23038489868d&sid=sitelife.nwfdailynews.com |archive-date=September 28, 2011 |df=mdy-all }}</ref>

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>
