It uses solid propellant and is 13 feet (4.0 m) long and 24 inches (610 mm) in diameter, and the longest-range variants can fly up to 190 miles (300 km).[9] The missiles can be fired from the tracked M270 Multiple Launch Rocket System (MLRS) and the wheeled M142 High Mobility Artillery Rocket System (HIMARS).
An ATACMS launch container (pod) has one rocket but a lid patterned with six circles like a standard MLRS rocket lid to prevent an enemy from discerning what type of missile is loaded.[1]
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.[10] The AirLand Battle and Follow-on Forces Attack doctrines, which emerged in the late 1970s and early 1980s, necessitated a conventional-armed (hence much more accurate) missile to strike enemy reserves, so the United States Army Aviation and Missile Command sponsored the Simplified Inertial Guidance Demonstrator (SIG-D) program.[10]
Within this program, Ling-Temco-Vought developed a solid-fuel analog of the MGM-52 Lance missile, designated T-22,[11] with a new RLG-based inertial guidance package, which demonstrated unprecedented accuracy.[10] 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 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.[12][13]
Development of the missile now known as ATACMS started in 1980, when the 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 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.[12]
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 redesignated as the Army Tactical Missile System (ATACMS).[12]
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 vehicles, 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 weapon system, which should be used for the so-called "deep interdiction" (some sort of preventive measure, the prototype of which is air interdiction when airforce only have been used) - 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 refineries and other industry, that way slowing down logistics and/or providing and/or supporting and, therefore, advancing enemy troops with the aim of tactical, even albeit short-term, superiority of allied troops, which can significantly affect the military theater in a positive way,[14][15][16][17][18] - using conventional or nuclear weapons on the battlefield. Although both services were to participate in the development of the weapon, it was the US Army who led the JTACMS program.[19][20]
As of personalities the program initially was 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),[21] 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[22] and in 1980, heading the TRADOC program at Fort Sill in the direction of MLRS, spoke rather defiantly about field army systems, where, in particular, he compared the struggle of the US Army for limited resources during the development of new systems with bow wave, which prevents the ship from accelerating, and military projects are either canceled or refinanced by the state, with waves diverging from it,[23] and was noticed by DARCOM.[24] In April 1984, he was transferred to be the head of the TOW project, and in the current project he was replaced by Colonel William J. Fiorentino, who by that time had already been the head of the Pershing Project Manager's Office for more than 5 years, which during his leadership developed two-stage solid fuel mobile-launched ballistic missiles with a nuclear warhead both short (Pershing) and medium (Pershing II) ranged.[25] Dr. Billy Tidwell who was program manager during JTACMS while and Acting Program Manager for a short period.[26]
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.[27]
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.[28]
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.[29]
Starting from at least the end of year 1986 ATACMS program was led by Colonel Thomas J. Kunhart.[30]
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 warhead, and adds a proximity fuze option to obtain area effects. Deliveries were projected to start in 2018. The ATACMS SLEP is a bridging initiative to provide time to complete analysis and development of a successor capability to the aging ATACMS stockpile, which could be ready around 2022.[needs update][31]
The National Defense Authorization Act for Fiscal Year 2023 authorized the production and procurement of up to 1,700 additional ATACMS, but this was not funded by the 2023 Defense Appropriations Act.[32][33][needs update]
In January 2015, Lockheed Martin received a contract to develop and test new hardware for Block I ATACMS missiles to eliminate the risk of unexploded ordnance by 2016.[4][5] The first modernized Tactical Missile System (TACMS) was delivered in September 2016 with updated guidance electronics and added capability to defeat area targets using a unitary warhead, without leaving behind unexploded ordnance.[34][35] Lockheed was awarded a production contract for launch assemblies as part of the SLEP in August 2017.[36] In 2021, Lockheed Martin was contracted to upgrade existing M39 munitions to the M57 variant with a WDU-18/B warhead from the Harpoon missile by 2024.[37]
A plan announced in October 2016 to add an existing seeker to enable the ATACMS to strike moving targets on land and at sea[38] was terminated in December 2020 to pursue other missile efforts.[39]
Starting in 2016, in view of some lagging in the world arms race, where ATACMS had become outdated, Long-Range Precision Fires (LRPF) began to be developed,[40] which was later renamed Precision Strike Missile (PrSM), with the idea of replacing ATACMS missiles with the "Increment 1" phase (version) of PrSM.[41][42][43] That exact replacement began to fill the U.S. Army in late 2023.[44]

The ATACMS was first used in combat in 1991: 32 were fired from the M270 MLRS during Operation Desert Storm.[71] In 2003, more than 450 were fired in Operation Iraqi Freedom.[72] As of early 2015, more than 560 ATACMS missiles had been used in combat.[4][5]
Starting from October 2023 Ukraine began using the earliest (short-ranged) versions of ATACMS during the Russian invasion of Ukraine.[73] These missiles were meant to threaten the Russian-occupied "land corridor" to Crimea in the southern part of Ukraine[74] as well as the vast majority of the Russian-operated air bases in the north of Crimea, which would theoretically complicate the use of attack helicopters, previously[citation needed] based there, by Russia against Ukrainian targets.[47][75]
Starting from 19 February 2024 there were rumors about possible near-future use of later (longer-ranged) versions of ATACMS by Ukraine,[76] which were shortly proven correct, when an ATACMS missile attack on the Russian-occupied Dzhankoi air base, positioned much further from the nearest Ukraine-controlled territory than earlier versions of ATACMS' strike range, resulting in six main explosions and several reported secondary explosions.[77] It was then officially confirmed when U.S. officials revealed Ukraine had already received and deployed the missiles to a combat ready status a month prior.[78][79][80][81][82][83]
On 23 June 2024 an incident occurred during an attack on Sevastopol, where Russian air defense missiles were fired at multiple ATACMS missiles resulting in explosions that caused 2 to 4 deaths and more than 150 injuries on Uchkiivka Beach, where locals reported that no air raid warning had taken place and therefore people on the beach were not able to evacuate.[84][85]
In September 2024, Russian President Vladimir Putin threatened retaliation for attacks on Russian territory.[86] Experts said Putin's threats are aimed at dissuading the United States, the United Kingdom and France from allowing Ukraine to use Western-supplied long-range missiles such as the Storm Shadow and ATACMS in strikes against Russia.[87]
On 17 November 2024, the United States changed policy, allowing the use of ATACMS for military targets inside mainland Russia.[88][89]
On 19 November 2024, the Ukrainian military claimed to have struck a Russian ammunition depot in Karachev, Bryansk Oblast using ATACMS for the first time.[90] [91]
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.[92]
On July 1, 2024, Russia claimed to have recovered an ATACMS missile guidance system intact, and stated that Russian officials are studying the guidance system to "identify any weak spots".[93]
