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).

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.<ref name="military-today" />
