Counting the United States and the NATO countries that helped develop it, some 13 nations currently use the MLRS, including Israel, South Korea, Egypt, and Norway. Many of these nations have simply bought launchers and rockets directly from the United States while others have undertaken production on their own. Since many thousands of Soviet-pattern MLRs are in service around the globe, the MLRS is not the world’s most numerous rocket system, although it is likely the most widely used Western launcher in current service.
On February 24, 1991, the ground phase of Operation Desert Storm began. Over the next four days, the soldiers of an international coalition, formed to eject the Iraqi army of Saddam Hussein from the neighboring nation of Kuwait, carried out a whirlwind offensive that quickly overwhelmed their foe. During this time, tens of thousands of Iraqi soldiers were taken prisoner.
Many of them, arms thrust upward in a sign of surrender, said one thing when they were taken into custody: “No more steel rain.” For weeks before the ground attack, these men had been systematically pummeled by the entire range of weaponry available to their opponents—B-52 bombing strikes, air attacks using tons of precision “smart” weapons, plus many more thousands of tons of traditional unguided bombs and rockets. Added to this was the close air support of fighter-bomber aircraft and attack helicopters. Artillery barrages dropped down on them by the dozens and hundreds, adding yet another level to the pounding they received.
The cries of “no more steel rain” applied to none of these, however. Instead, it was the nickname of a deadly new artillery weapon seeing its debut in combat: the M270 Multiple Launch Rocket System, or MLRS. Batteries of these weapons had been deployed to the Gulf with U.S. and British forces, who used them to blanket their target areas with hundreds of rockets releasing thousands of explosive submunitions, or bomblets, that devastated armored vehicles, trucks, equipment, and men. Volleys of rockets pounded the hapless Iraqi troops and paved the way for the sweeping infantry and armor assaults that followed. The MLRS proved itself alongside such other late-Cold War weapons as the M1 Abrams tank, M2 Bradley Fighting Vehicle, and AH64 Apache helicopter. Like these weapons, the MLRS had its origins in the 1970s development programs of the post-Vietnam era.
The MLRS Concept Takes Shape
During the late 1960s and early 1970s, America’s involvement in the Vietnam War drew most of the focus away from the traditional enemies of the time, the Soviet Union and its Warsaw Pact allies. As the United States gradually withdrew from the conflict in Asia, its attention once again returned to Eastern Europe, and the U.S. Army was not happy encountering the Russians’ new claws. The Soviets had taken advantage of America’s distraction to build up its conventional forces to unprecedented levels. The Warsaw Pact now sat across the Iron Curtain with tens of thousands of new tanks, armored vehicles, cannons, and rocket artillery pieces. Artillery had always weighed heavily in Soviet planning, and they now had new, longer-ranged cannons than most comparable American weapons.
The disparity in rocket artillery was even more one-sided. Soviet tactics used barrages of thousands of rockets fired from truck-mounted multiple rocket launchers (MRLs) such as the BM-21. American artillery was only scantily supplied with rocket launchers, many of them left over from World War II. With some exceptions, U.S. planners heavily favored cannon artillery, primarily for its relative accuracy. Rockets at that time were considered “area fire” weapons; that is, they were fired en masse at an area of ground where the enemy was thought to be, rather than at a “point” target such as a bunker or trenchline. Existing rockets simply were not accurate enough for such pinpoint work, although they packed quite a punch and tended to have a terrifying psychological effect on the enemy. The Soviets were willing to saturate a target area with rockets, figuring that some, at least, would find their mark. For American artillerists, weaned on the concepts of accuracy and economy of expenditure in ammunition, large-scale use of indiscriminate rockets simply was not palatable.
A number of occurrences changed that mindset. In 1973, the Arab-Israeli War broke out. Attrition rates in that conflict were far higher than expected, greater than any possible rate of replacement for lost armor and aircraft. One of the more effective Israeli tactics had been to hit enemy Surface-to-Air Missile (SAM) sites with MRLs. The American military establishment noted this. It also noted that in the event of war in Europe, NATO would have to fight outnumbered against a well-equipped enemy in intense, destructive combat.
After long debate, the U.S. Army finally wrote a requirement for a new rocket launcher in March 1974, calling it the GSRS, or General Support Rocket System. It would be used to engage enemy air defenses and for counterbattery fire, neutralizing opposing artillery. The new launcher would have long-range and massive firepower, freeing the cannon units to provide close support to the infantry and armor. Several NATO allies, including the United Kingdom, France, and West Germany, were consulted and agreed to collaborate on the project. Since the Europeans already had looked at a similar system independently, their name was adopted, changing GSRS to MLRS.
Design and Development
Actual development began in September 1977, undertaken by the Boeing and Vought Aerospace companies, which beat out three other competitors for the contract. Development continued into the 1980s and eventually became the highest priority for the Field Artillery School, which considered it the Army’s “most spectacular new weapons system.” After initial testing proved successful, the MLRS was adopted, with the first production models, designated M270, arriving at Fort Sill, Oklahoma, in August 1982. The first operational battery of M270s was formed in March 1983, and the new unit was sent to West Germany the following September. These batteries were composed of three platoons of three launchers each, a total of nine launchers per battery. By 1987, 25 such batteries were in service.
The basic M270 was a self-propelled armored vehicle that mated two main subcomponents: the Launcher-Loader Module (LLM) containing the rocket pods and the hardware needed to load and unload them and the carrier vehicle, essentially an enlarged version of the Bradley Fighting Vehicle chassis. The vehicle was not quite 23 feet long, 9.5 feet wide, and 8.5 feet high. It weighed 52,990 pounds ready for combat. The three-man crew sat in a cab above the engine compartment. This cab was armored to protect against small-arms fire and artillery fragments. The engine was a Cummins 8-cylinder diesel developing 500 horsepower for a top speed of 40 miles per hour and a range of 483 kilometers. Directly behind the cab was the LLM, which carried two pods of six rockets each, one next to the other. For firing, the LLM raised and rotated to point to the vehicle’s side. It could fire single rockets or any number up to its full load of 12 within 60 seconds.
The crew consisted of a crew chief, gunner, and driver. The crew chief commanded the vehicle, oversaw firing operations, and performed checks of the other two crewmen. The gunner operated a firing panel to aim and fire the rockets at selected targets. The M270’s computer calculated the data for the rocket’s direction of fire, point of impact, and range; these calculations were based on information received digitally via radio or entered manually by the gunner. The driver operated the M270 and performed maintenance.
The heart and purpose of the M270 were its munitions. The basic rocket was the M26, with a range of 32 kilometers. It carried 644 grenade-sized submunitions. A single M270 could blanket a 600-square-meter area with 7,728 bomblets, devastating to men, material, and light vehicles, with a limited effect on armored vehicles. One battery of MLRS firing a complete volley of 108 rockets had the equivalent firepower of 33 battalions of cannon artillery. These rockets were packaged in pods of six rounds each. Rockets were only part of the picture, however. The M270 also fired the M39 Army Tactical Missile System (ATACMS) missile, each launcher carrying two missiles in place of the normal 12 rockets. The ATACMS carried 950 bomblets and had a range of 165 kilometers, giving MLRS the ability to range deep in enemy territory, hitting command posts, logistics depots, air defenses, and assembly areas for advancing units. ATACMS started development in 1985 and was rushed into service for Desert Storm.
The MLRS Doctrine
The doctrine for the use of MLRS sought to take advantage of its mobility and firepower. To avoid the expected Soviet counterbattery fire, M270s would spread out individually and hide themselves until needed for a mission. The launcher would then move to a firing position, launch its rockets, and immediately move away, hopefully before the Soviets could calculate the launch point using radar and fire on it. The M270 crew would then proceed to a reloading point, load fresh rocket pods, and move to a completely new hiding position near a different firing point. This would prevent the enemy from destroying the valuable launchers as they poured volley after volley into the advancing Soviet armored hordes.
