Multiple rocket launcher

A multiple rocket launcher (MRL) or multiple launch rocket system (MLRS) is a type of rocket artillery system. Rockets have different capabilities than artillery, like longer range, and different payloads, for example considerably larger warheads, or multiple warheads. Unguided rocket artillery is notoriously inaccurate and slow to reload, compared to artillery. To overcome this, rockets are combined in systems that can launch multiple rockets simultaneously. Modern rockets can use GPS or inertial guidance, to combine the advantages of rockets with high accuracy.

History

The first multiple rocket launchers were made in Song-dynasty China. It was a primitive design where multiple fire arrows were fired from a gunpowder box. These also appeared later, in an expanded version, in the Joseon Dynasty of Korea.

World War Two

The first self-propelled multiple rocket launchers — and arguably the most famous — were the Soviet BM-13 Katyushas, first used during World War II and exported to Soviet allies afterwards. They were simple systems in which a rack of launch rails was mounted on the back of a truck. This set the template for modern multiple rocket launchers. The Americans mounted tubular launchers atop M4 Sherman tanks to create the T34 Calliope rocket launching tank, only used in small numbers, as their closest equivalent to the Katyusha. The Germans began using a towed six-tube multiple rocket launcher during World War Two, the Nebelwerfer, also called the "screaming mimi" by the allies.

M270 Multiple Launch Rocket System

The M270 Multiple Launch Rocket System (M270 MLRS) is an armored, self-propelled, multiple rocket launcher; a type of rocket artillery.

Since the first M270s were delivered to the U.S. Army in 1983, the MLRS has been adopted by several NATO countries. Some 1,300 M270 systems have been manufactured in the United States and in Europe, along with more than 700,000 rockets. The production of the M270 ended in 2003, when a last batch was delivered to the Egyptian Army.

Overview

The weapon can fire guided and unguided projectiles up to 42 km (26 mi). Firing ballistic missiles, such as the U.S. Army Tactical Missile System—ATACMS, it can hit targets 300 km (190 mi) away; the warhead in such shots reaches an altitude of about 50 km (164,000 ft). The M270 can be used in shoot-and-scoot tactics, firing its rockets rapidly, then moving away to avoid counter-battery fire.

MLRS was developed jointly by the United Kingdom, United States, Germany, France and Italy. It was developed from the older General Support Rocket System (GSRS). The M270 MLRS weapons system is collectively known as the M270 MLRS Self-propelled Loader/Launcher (SPLL). The SPLL is composed of three primary subsystems: the M269 Loader Launcher Module (LLM), which also houses the electronic Fire Control System, is mated to the M993 Carrier Vehicle. The M993 is a derivative of the Bradley Fighting Vehicle chassis.

United States Army

The United States Army (USA) is the largest branch of the United States Armed Forces and performs land-based military operations. It is one of the seven uniformed services of the United States, and is designated as the Army of the United States in the United States Constitution, Article 2, Section 2, Clause 1 and United States Code, Title 10, Subtitle B, Chapter 301, Section 3001. As the largest and senior branch of the U.S. military, the modern U.S. Army has its roots in the Continental Army, which was formed (14 June 1775) to fight the American Revolutionary War (1775–83)—before the U.S. was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784, to replace the disbanded Continental Army. The United States Army considers itself descended from the Continental Army, and dates its institutional inception from the origin of that armed force in 1775.
