The '''MGM-140 Army Tactical Missile System''' ('''ATACMS''' {{IPAc-en|ə|ˈ|t|æ|k|ə|m|z}}) is a [[supersonic]] [[tactical ballistic missile]] designed and manufactured by the American defense company [[Ling-Temco-Vought]] (LTV), and later, through acquisitions, [[Lockheed Martin]].

The missile uses [[solid-propellant rocket|solid propellant]] and is {{convert|13|ft}} long and {{convert|24|in}} in diameter, and the longest-range variants can fly up to {{convert|300|km|mi|order=flip}}.<ref>{{Cite web|date=25 March 2021|title=Army Tactical Missile System Block IA Unitary|url=https://www.lockheedmartin.com/en-us/products/army-tactical-missile-system-block-ia-unitary-atacms.html|access-date=20 December 2021|website=Lockheed Martin |archive-date=20 December 2021|archive-url= https://web.archive.org/web/20211220055459/https://www.lockheedmartin.com/en-us/products/army-tactical-missile-system-block-ia-unitary-atacms.html |url-status=live}}</ref> It can be fired from the [[Continuous track|track]]ed [[M270 Multiple Launch Rocket System]] (MLRS) and the wheeled [[M142 HIMARS|M142 High Mobility Artillery Rocket System]] (HIMARS).

==History==
=== Pre-development ===
The concept of a conventional tactical ballistic missile was made possible by the doctrinal shift of the late [[Cold War]], which rejected the indispensability of an early nuclear strike on the [[Warsaw Pact]] forces in the event the Cold War went hot.<ref name="Romanczuk">{{Cite report|url=https://apps.dtic.mil/sti/citations/ADA517010|title=Lessons From Army System Developments.

Within this program, [[Ling-Temco-Vought]] developed a solid-fuel analog of the [[MGM-52 Lance]] missile, designated T-22,<ref>{{Cite web|url=https://space.skyrocket.de/doc_lau/t-22.htm|title=T-22 (SIG-D, Assault Bereaker) SRBM|access-date=7 September 2020|archive-date=6 February 2018|archive-url=https://web.archive.org/web/20180206114045/http://space.skyrocket.de/doc_lau/t-22.htm|url-status=live}}</ref> with a new [[Ring laser gyroscope|RLG]]-based [[Inertial navigation system|inertial guidance package]], which demonstrated unprecedented accuracy.<ref name="Romanczuk" /> In 1978, [[DARPA]] started the [[Assault Breaker]] technology demonstration program to attack armor formations with many mobile hard targets at standoff ranges. It used the T-22 missile and the Patriot-based [[Martin Marietta]] T-16 missile with cluster warheads.

In March 1980 the [[U.S. Army]] decided to replace the Lance with a similar nuclear, but also chemical or biological, tipped solid-fuel missile with simplified usability dubbed the Corps Support Weapon System (CSWS). In a year, concerned about the fact Army started to develop the weapon with a similar objectives to interdict the [[second-echelon]] massed targets to already developing by [[USAF]]'s Conventional Standoff Weapon (CSW) program with only difference of surface/air-launched and both positioned as the part of same Short Range Nuclear Forces of Non-Strategic Nuclear Force Program, the [[United States Department of Defense|Department of Defense]] subdued CSWS Project Office (Provisional) to [[MICOM]] renaming it to the System Development Office. That new office acquired the [[Assault Breaker]] effort thus started to manage the Assault Breaker and CSWS efforts together, that way slowly summing up and moving forward the weapon development progress for the JTACMS program to be сreated.<ref name="history.redstone.army.mil">{{Cite web |title=The United States Army |url=https://history.redstone.army.mil/miss-tacms.html |access-date=15 September 2024 |website=history.redstone.army.mil |archive-date=6 March 2015 |archive-url=https://web.archive.org/web/20150306212751/http://history.redstone.army.mil/miss-tacms.html |url-status=live }}</ref><ref>{{Google books|oB8UilYjO2wC|Defense Department Authorization and Oversight: Research, development, test, and evaluation.&nbsp;United States,&nbsp;U.S. Government Printing Office,&nbsp;1983.|page=158|keywords="Conventional Standoff Weapon"}}</ref>

=== Development ===
Development of the missile now known as ATACMS started in 1980, when the [[United States Army|U.S. Army]] decided to replace the Lance with a similar nuclear, but also chemical or biological, tipped solid-fuel missile dubbed the Corps Support Weapon System (CSWS). Concerned that two branches were developing too many similar missiles with different warheads, the [[United States Department of Defense|Department of Defense]] merged the program with DARPA's Assault Breaker in 1981, and with [[United States Air Force]] (USAF)'s Conventional Standoff Weapon (CSW) in 1982–1983.<ref name="history.redstone.army.mil" />

The new missile system, designated Joint Tactical Missile System (JTACMS), soon encountered USAF resistance to the idea of an [[air-launched ballistic missile]]. As a result, in 1984 the USAF ended its participation in the non-cruise missile portion of the program, leading to the missile being re-designated as the Army Tactical Missile System (ATACMS).<ref name="history.redstone.army.mil"/>

==== Details ====
In [[fiscal year]] 1982, the [[United States House Committee on Appropriations]] approved the Corps Support Weapon System (CSWS) program, which was the successor to the [[US Army]] [[Assault Breaker]] program in cooperation with [[DARPA]], was merged with the Conventional Standoff Weapon (CSW) [[US Air Force]] and renamed the Joint Tactical Missile System (JTACMS), the goal of which was to create a weapon that meets the combined requirements of both programs, namely, that it can attack and destroy the [[second-echelon]] of enemy forces, in particular [[armored vehicle]]s, and scatter submunitions against such vehicles. In this project, it was planned to use the technologies of Assault Breaker to develop a [[Surface-to-surface missile|surface-to-surface]] weapon system, which should be used for the so-called "deep interdiction" (some sort of preventive measure, the prototype of which is [[air interdiction]] used by air force) – by which is meant the destruction or causing significant damage by the joint activity of air and ground forces to the specific distant from the [[front line]] targets, such as buildings, bridges, [[oil refinery|oil refineries]] and other [[Industry (manufacturing)|industry]], that way slowing down logistics and/or providing and/or supporting and, therefore, advancing enemy troops with the aim of [[Military tactics|tactical]], even albeit short-term, superiority of allied troops, which can significantly affect the [[military theater]] in a positive way,<ref>{{cite journal | url=https://ausairpower.net/longbow-aa.html | title=AH-64D Apache Longbow Flight Report | journal=Australian Aviation | date=April 1999 | volume=1999 | last1=Kopp | first1=Carlo }}</ref><ref>{{cite web | url=http://www.deneldynamics.co.za/products/missiles/stand-off-weapons/al-tariq- | title=Al-Tariq &#124; Denel Dynamics }}</ref><ref>{{cite web |last1=Baumann |first1=Robert |title=Deep Operations: Theoretical Approaches to Fighting Deep |url=https://www.armyupress.army.mil/Portals/7/combat-studies-institute/images/LSCO%20DeepOps%20book%20interactive%20with%20cover%20spread%2012Nov21.pdf |publisher=[[United States Army Combined Arms Center]] |access-date=4 October 2024 |archive-url=https://web.archive.org/web/20211208183737/https://www.armyupress.army.mil/Portals/7/combat-studies-institute/images/LSCO%20DeepOps%20book%20interactive%20with%20cover%20spread%2012Nov21.pdf |archive-date=8 December 2021 |date=November 2021 |url-status=live}}</ref><ref>{{cite web |last1=Laughbaum |first1=R.

The program was initially led by Colonel James B. Lincoln, who was a full-time and continuous student at numerous military schools (from 1960, when he graduated from the [[United States Military Academy]], until 1980, when he graduated from [[Industrial College of the Armed Forces]]),<ref>{{cite web |url=https://history.redstone.army.mil/miss-jamesblincoln.html |archive-url=https://web.archive.org/web/20240820093904/https://history.redstone.army.mil/miss-jamesblincoln.html |archive-date=20 August 2024 |title=Colonel James Lincoln}}</ref> in 1977 on the basis of [[Defense Systems Management College]] graduated with a [[thesis]] of "Managing Total Acquisition Time: A New Priority for Major Weapon Systems", where, in particular, he focused on the significant decrease in the pace of procurement of the main missile complexes compared to 1971<ref>{{Google books|bXEMGFURzJ0C|Concepts: The Journal of Defense Systems Acquisition Management. United States, Defense Systems Management College, 1980.|page=19|keywords="james B.

In FY 1984 Congress prohibited the development of a nuclear warhead for JTACMS, despite the Army claiming it could place US forces at a disadvantage if it became necessary to make the system nuclear-capable. In FY 1985 the Army denied having R&D funds programmed for the development of a JTACMS nuclear warhead.<ref>{{cite book | url=https://books.google.com/books?id=Ta80o5lxMAsC&dq=JTACMS+Project+manager&pg=PA425 | title=Department of Defense appropriations for fiscal year 1985: Hearings before a subcommittee of the Committee on Appropriations, United States Senate, Ninety-eighth Congress, second session | date=1984 | publisher=U.S. Government Printing Office |pages = 422–425 }}</ref>

On May, 22th, 1984 the U.S. Army and USAF signed an agreeing on a list of 31 initiatives. Item 18 on that list states  about services will develop a different types of same rocket for each of it – preferences for Army was a development of shorter-ranged  ground-launched system, for air-force – air-launched system.<ref name="auto2">{{cite book | url=https://books.google.com/books?id=Ta80o5lxMAsC&dq=JTACMS+Project+manager&pg=PA425 | title=Department of Defense appropriations for fiscal year 1985: Hearings before a subcommittee of the Committee on Appropriations, United States Senate, Ninety-eighth Congress, second session | date=1984 | publisher=U.S. Government Printing Office }}</ref>

JTACMS was intended to be a jointly funded program with NATO allies; the [[United Kingdom]], [[Federal Republic of Germany]], [[Belgium]], [[the Netherlands]] and [[Italy]] were initially contacted about joining the program, with the British and Germans expressing interest, while the others declined due to lacking adequate funds.<ref name="auto2"/>

Starting from at least the end of year 1986, the ATACMS program was led by Colonel Thomas J. Kunhart.<ref>{{Google books|hoEEqewyxswC|Army RD & A Magazine.&nbsp;United States,&nbsp;HQ, U.S. Army Materiel Command,&nbsp;1986.|keywords="Kunhart"}}</ref>

=== Production ===
In March 1986, Ling-Temco-Vought won the contract for the missile design. The system was assigned the MGM-140 designation. The first test launch came two years later, thanks to earlier experience of the company with previous programs.

In 2007, the U.S. Army terminated the ATACMS program due to cost, ending the ability to replenish stocks. To sustain the remaining inventory, the ATACMS Service Life Extension Program (SLEP) was launched, which refurbishes or replaces propulsion and navigation systems, replaces [[cluster munition]] warheads with the unitary [[Blast-fragmentation|blast fragmentation]] warhead, and adds a [[proximity fuze]] option to obtain area effects.

=== EW vs usability ===

The ATACMS uses multiple inertial navigation units knitted together with software, so it is reportedly able to maintain accuracy when GPS is lost due to [[electronic warfare]] better than other GPS-guided weapons.<ref>[https://breakingdefense.com/2024/05/taking-aim-army-leaders-ponder-mix-of-precision-munitions-vs-conventional/ Taking aim: Army leaders ponder mix of precision munitions vs conventional].
