Multiple Launch Rocket System (MLRS)The M270 and M270A1 Multiple Launch Rocket System (MLRS) provides counterfire and suppression of enemy air defenses, light materiel, and personnel targets at ranges from 15 to 300+ kilometers. The MLRS is a high-mobility automatic system that is capable of supporting and delivering free flight basic, extended-range and guided rockets as well as the Army Tactical Missile System (ATACMS) missiles.
M270 and M270A1 Multiple Launch Rocket System (MLRS) Launcher UnitThe MLRS Launcher Unit comprises an M270 launcher loaded with 12 rockets, packaged in two six-rocket pods. The MLRS launcher, which is mounted on a stretched M2 Bradley chassis, is a highly automated self-loading and self-aiming system. It contains a fire control computer that integrates the vehicle and rocket launching operations. Without leaving the cab, the crew of three (driver, gunner and section chief) can fire up to twelve MLRS rockets in less than 60 seconds.
The M985 HEMTT 8x8 truck with HD Materiel Handling Crane carries resupply rocket pods for the MLRS. The M142 High Mobility Artillery Rocket System (HIMARS) fires the same munitions, but is a wheeled launcher platform with a single rocket pod. MLRS Munitions: History and CharacteristicsMultiple Launch Rocket System (MLRS) was introduced in the early 1980s, originally known as the General Support Rocket System (GSRS) when it was fielded in 1983. It was designed to supplement division- and corps-level cannons and deliver large volumes of fires in a very short time against critical, time-sensitive targets. The first MLRS munition (M26) was a free-flight artillery rocket that greatly improved the conventional, indirect fire capability of the Army for counterfire, suppression of enemy air defenses, and to destroy light materiel and personnel targets. The natural dispersion MLRS rockets’ payloads allowed most targets to be engaged without multiple aiming points. However, MLRS accuracy restricted it to area targets in open terrain where collateral damage was not an issue. Additionally, with a range of 31.5 kilometers, MLRS was outranged by a majority of foreign MRLs. Therefore, MLRS improvements focused on upgrading launcher responsiveness and enhancing the range and precision of its munitions. MLRS performed well during Operation Desert Storm in 1991 in the Gulf, but its rockets and submunitions raised serious concerns. Many Iraqi artillery assets outranged MLRS rockets. Also, the high submunition dud rate caused concern for the safety of friendly soldiers or noncombatants passing through impact areas. These shortcomings resulted in the requirement for a rocket with extended range and a substantially lower submunition dud rate. As an interim measure until a guided MLRS could be produced, the extended-range MLRS rocket (M26A1 and A2 ER-MLRS) with a range of 45 kilometers was developed, although limited quantities of the rocket were manufactured. In Bosnia and Kosovo, the MLRS family of munitions (MFOM) with a dual-purpose improved conventional munition (DPICM) warhead severely restricted the targets considered for engagement. Even though MLRS was deployed, not one rocket was fired because of the lack of precision and potential for collateral damage as well as the high submunition dud rate. GMLRS. The Army’s ability to protect itself from long distance attack was eroded over time with the proliferation of long-range rocket and cannon systems. To counter this, the US Army Missile Command’s Research, Development and Engineering Center, Redstone Arsenal, Huntsville, AL, with support from private industry, began working on a Guided MLRS (GMLRS) to replace the M26 and ER-MLRS (M26A1 and A2) rockets. Guided Rocket DPICM (M30) GMLRS extends the range of MLRS fires to more than 60 kilometers and substantially improve MLRS accuracy. GMLRS provides the same lethality as the M26 and M26A2 with far fewer rockets. The Guided Unitary Rocket (XM31 and follow on) provides organic capability to deliver fires in all types of terrain and weather within a fully networked architecture to provide destructive fires at both point and area targets and protective and suppressive fires in the required scalable quantity to support the maneuver commander. It reduces collateral damage to civilian property and noncombatants, decrease the risk of unexploded ordnance on the battlefield and is employable in heavy snow and forested, urban, complex and restrictive terrain. Compliance with the Joint Technical Architecture (JTA) supports HIMARS and M270A1 MLRS Launcher programs, and is required by both Department of the Army and Office of the Secretary of Defense. The MLRS family of munitions, for MLRS and HIMARS, is packaged in pods of six. Another option is to fire a single Army Tactical Missile (ATACMS) Family of Munitions (AFOM) missile, including precision munitions, to a range of 300km. The table of MLRS munitions includes:
