The MGM-140 Army Tactical Missile System (ATacMS) is a surface-to-surface missile (SSM) manufactured by Lockheed Martin. It has a range of over 160 kilometres (100 mi), with solid propellant, and is 4.0 metres (13 ft) high and 610 millimetres (24 in) in diameter.

The ATACMS can be fired from multiple rocket launchers, including the M270 MLRS, and HIMARS. An ATACMS launch container has a lid patterned with six circles like a standard MLRS rocket lid.

The first use of the ATACMS in a combat capability was during Operation Desert Storm, where a total of 32 were fired from the M270 MLRS.[5] During the Operation Iraqi Freedom more than 450 missiles were fired.[6] As of early 2015, over 560 ATACMS missiles had been fired in combat.[1][2]


MGM-140A – Block I[edit]

Previously M39,[7] unguided missile contains 950 M74 anti-personnel/anti-materiel (APAM) submunitions with a range of 128 kilometres (80 mi).[8]

MGM-140B – Block IA[edit]

Previously M39A1,[7] missile uses GPS/INS guidance, carries 275 M74 submunitions and has a 165 kilometres (103 mi) range.[8][9]

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.[1][2]

MGM-164 ATacMS – Block II[edit]

A Block II variant (initially designated MGM-140C or, previously, M39A3[7]) was designed to carry a payload of 13 Brilliant Anti-Tank (BAT) munitions manufactured by Northrop Grumman. However, in late 2003 the U.S. Army terminated the funding for the BAT-equipped ATACMS and therefore the MGM-164A never became fully operational.[10]

MGM-168 ATacMS – Block IVA[edit]

Originally designated Block IA Unitary (MGM-140E), the new Block IVA variant was designed to carry a 230 kilograms (500 lb) unitary HE warhead instead of the M74 bomblets. It uses the same GPS/INS guidance as the MGM-140B. The development contract was placed in December 2000, and flight-testing began in April 2001. The first production contract was awarded in March 2002.[11] The range has been increased to some 300 kilometres (190 mi), limited more by the legal provisions of the Missile Technology Control Regime (MTCR) than technical considerations.
