The M142 HIMARS

About the HIMARS:





The Lockheed Martin M142 High Mobility Artillery Rocket System (HIMARS) is a full spectrum, combat proven, all weather, 24/7 lethal and responsive, precision strike weapon system.

The HIMARS launcher is a C-130 transportable, wheeled, indirect fire, rocket/missile launcher capable of engaging a variety of targets while firing all rockets and missiles in the current and future Multiple Launch Rocket System (MLRS) family of munitions and Army Tactical Missile System (ATACMS) family of munitions. The HIMARS battery can fire six MLRS rockets or one ATACMS out to ranges of as much as 185 miles (300 km).

The two currently fielded MLRS rocket variants are the M30 GMLRS with Dual Purpose Improved Conventional Munitions (DPICM) and the M31 GMLRS Unitary, a 200-pound class high explosive warhead. The M31 (the only variant currently being purchased by the U.S. military) integrates a multi-mode fuze and high explosive warhead, making it an all-weather, low collateral damage, precision strike rocket. It employs GPS/INS guidance and has small canards on the rocket nose to improve accuracy. The M31 has a range of over 43.5 miles (70 km). With over 2,100 rockets fired in support of Overseas Contingency Operations (OCO) by the Army, Marine Corps and United Kingdom, the M31 rocket has demonstrated high effectiveness and low collateral damage while supporting troops in combat.

The HIMARS launcher has extensive commonality in both functionality and operational employment with the MLRS M270A1 tracked launcher used by the GMLRS. It consists of a Fire Control System, a carrier (FMTV 5-ton XM1140A1 automotive chassis) and a launcher-loader module that performs all operations necessary to complete a fire mission. HIMARS also satisfies the U.S. Army's digitization requirements by interfacing with the Advanced Field Artillery Tactical Data System (AFATDS) fire support command and control system.

HIMARS, as part of the Fires Brigade, provides fires that shape, shield and isolate the battle space and while using both precision GMLRS and ATACMS Unitary munitions, HIMARS provides close support fires for troops in contact in both open and urban terrain. The HIMARS provides U.S. and allied forces with a flexible and lethal rocket/missile capability. HIMARS units can be quickly tailored for centralized or decentralized execution throughout the entire battle space in support of ground forces. The program also includes training devices for tactical training, classroom training, and handling exercises for optimal performance.

HIMARS has been deployed to both Operation Iraqi Freedom and Operation Enduring Freedom by both U.S. Army and Marine Corps units.



Price/Cost:

The full M142 HIMARS System costs $3.48 million of which $2.95 million is for the launcher and $0.53 million for the carrier. The M31 GMLRS Unitary Rockets used by the M142 HIMARS cost approximately $110,000 each (FY 2014). The M28A2 Reduced Range Practice Rockets (RRPR) used for training cost $7,000 each (FY 2014).



Mission/Role:

To provide 24-hour ground-based, responsive General Support/General Support Reinforcing (GS/GSR) indirect fire, which accurately engages targets at long ranges (37+ miles/60+ km) with high volumes of lethal fire under all weather conditions throughout all phases of combat operations ashore - including irregular warfare and distributed operations.



FY 2014 HIMARS DoD Program:


ARMY: FY 2014 funds in the amount of $6.1M procures and installs Enhanced Command and Control (C2), XM1140A1 Chassis Upgrades, Obsolescence Mitigation/Engineering Change Proposal Integration to include measures for other hardware and software required in support of launcher upgrades such as transparent armor protection and suspension improvements.

Marine Corps (USMC): FY 2014 funds in the amount of $5.5M will purchase RSS upgrades, Army program management and engineering support for HIMARS, GMLRS, and RRPRs (practice rockets).



FY 2015 HIMARS DoD Program:


ARMY: FY 2015 procurement funds in the amount of $6.0 million will purchase and install Enhanced Command and Control (C2), Obsolescence Mitigation/Engineering Change Proposal Integration to include measures for other hardware and software required in support of launcher upgrades such as transparent armor protection and suspension improvements.

Marine Corps (USMC): FY 2015 funds in the amount of 19.5 million will purchase 33 M31 GMLRS Unitary Rockets, RRPRs (practice rockets), RSS upgrades, Army program management, Alternative Warhead Program (AWP), and engineering support for HIMARS, GMLRS, and RRPRs. The increase from FY 14 is due to the start of the Alternative Warehead Program (AWP), and will resume procurement of RRPRs.
