United States Department of Defense - M270 Multiple Launch Rocket System

The M270 Multiple Launch Rocket System (M270 MLRS) is a multiple rocket launcher, a type of rocket artillery.

The first rocket systems were delivered to the U.S. Army in 1983. The system is in widespread use in the NATO countries and it has also been manufactured in Europe. Some 1,300 M270 systems have been manufactured, along with more than 700,000 rockets. The system has been used in the Gulf wars, where it proved itself as a practical and effective weapons system. The production of the M270 ended in 2003, when a last batch was delivered to the Egyptian army.

The system is capable of firing guided and unguided projectiles to a distance of up to 42 km (26.1 miles). Firing modern munitions (such as the U.S. Army Tactical Missile System—ATACMS) it is capable of reaching out to 300 km (186 miles) with the projectile reaching a maximal altitude of ~50 km (164,000 ft). The M270 is a very mobile unit, thus well suited for the so called shoot-and-scoot tactic: it can fire its rockets very rapidly and immediately move away to avoid the counter-battery fire.

MLRS was developed jointly by the United Kingdom, United States, Germany, and France. It was developed from the older General Support Rocket System (GSRS).

The rockets and ATACMS missiles are contained in interchangeable pods. Each pod contains six standard rockets or one guided ATACMS missile (the two types cannot be mixed). The launcher can hold two pods at a time, which it loads using an integrated crane. All twelve rockets or two ATACMS missiles can be fired in under a minute. One launcher firing twelve rockets can completely blanket one square kilometer with submunitions. For this reason, the MLRS is sometimes referred to as the "Grid Square Removal Service". The U.S. Army is currently working on developing and fielding unitary (one large warhead instead of submunitions) rocket and ATACMS variants, as well as a guided rocket.

MLRS has recently been upgraded with guided rounds. Phase I testing of a guided unitary round (XM31) was completed on an accelerated schedule in March 2006. Due to an Urgent Need Statement the guided unitary round has already been fielded and used in action in Iraq. Lockheed Martin also received a contract to convert existing M30 DPICM GMLRS rockets to the XM31 unitary variant.

MLRS Rockets and Missiles

The M270 system can fire MFOM, MLRS Family Of Munition rockets and artillery missiles, which are manufactured by a number of countries. These include:

o M26A1 (United States): Extended Range Rocket (ERR), with range of 45 km and using improved M85 submunitions.
o M26A2 (United States): As M26A1, but using M77 submunitions.
* M27 (United States): Completely inert training Launch Pod/Container to allow full loading cycle training.
* M28 (United States): Training rocket. M26 with three ballast containers and three smoke marking containers in place of submunition payload.
o M28A1 (United States): Reduced Range Practice Rocket (RRPR) with blunt nose. Range reduced to 9 km.
