The MGM-140 Army Tactical Missile System (ATacMS) is a surface-to-surface missile (SSM) manufactured by the American company Lockheed Martin. It has a range of over 100 miles (160 km), with solid propellant, and is 13 feet (4.0 m) high and 24 inches (610 mm) in diameter.
The ATACMS can be fired from multiple rocket launchers, including the M270 Multiple Launch Rocket System (MLRS), and M142 High Mobility Artillery Rocket System (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. During Operation Iraqi Freedom more than 450 missiles were fired. As of early 2015, over 560 ATACMS missiles had been fired in combat.
MGM-140A – Block I
MGM-140B – Block IA
MGM-164 ATacMS – Block II
A Block II variant (initially designated MGM-140C or, previously, M39A3) was designed to carry a payload of 13 Brilliant Anti-Tank 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.
MGM-168 ATacMS – Block IVA
Originally designated Block IA Unitary (MGM-140E), the new Block IVA variant substitutes a 500 pounds (230 kg) unitary HE warhead for 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. The range has been increased to some 190 miles (300 km), limited more by the legal provisions of the Missile Technology Control Regime (MTCR) than technical considerations.
In 2007, the 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 are 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.
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. The first modernized Tactical Missile System (TACMS) was delivered on 28 September 2016 with updated guidance electronics and added capability to defeat area targets using a unitary warhead without leaving behind unexploded ordnance. Lockheed was awarded a production contract for launch assemblies as part of the SLEP on 2 August 2017.
In October 2016, it was revealed that the ATACMS would be upgraded with an existing seeker to enable it to strike moving targets on land and at sea.
In March 2016, Lockheed Martin, Boeing, and Raytheon announced they would offer a missile to meet the U.S. Army's Long Range Precision Fires (LRPF) requirement to replace the ATACMS. The missile will use advanced propulsion to fly faster and further, out to 310 miles (500 km), while also being thinner and sleeker, increasing loadout to two per pod, doubling the number able to be carried by M270 MLRS and M142 HIMARS launchers. Lockheed and Raytheon will test-fire their submissions for the renamed Precision Strike Missile (PRSM) program in 2019, with the selected weapon planned to achieve Initial Operational Capability in 2023; the initial PRSM will only be able to hit stationary targets on land, but later versions will track moving targets on land and sea. If the United States withdraws from the INF Treaty, the range of the PRSM could be increased beyond the '499 km' limitation placed upon it by the treaty.
