    multiple rocket launcher mlrs multiple rocket launcher MLRS is designed to perform at any time and under different weather conditions combat missions for the defeat and destruction of weapons and capabilities of rocket artillery, the areas of concentration of forces and air defense equipment, trucks cars, light-armored armored vehicles, as well as a staging area, and technical positions.

    Originally developed variant intended to equip compounds tactical and operational-tactical level (division, building), named as a reactive system of general support GSRS (General Support Rocket System). In early 1976, began preparatory work for the development of the concept of its creation. In March 1976, representatives of five companies: (Boeing, Emerson Electric, Martin Marietta, Northrop and Vought (now Lockheed Martin Missiles and Fire Control Dallas) signed a contract to evaluate the concept of a reactive system of general support GSRS. In September 1977, representatives of firms Boing Aerospace and Vought Corporation signed a 29-month period of ratification (approval) of the competition to develop GSRS. Under the contract, each company has delivered three prototype combat vehicle and unguided rockets for the comparative tests on the missile range, White Sands (New Mexico). < / p>

    In early 1978, the management of research and development work in the field of missiles the U.S. Army has changed the direction of further development of the GSRS with the possibility of production in both the U.S. and Europe. The program was renamed the Multiple Launch Rocket System, or MLRS. In April 1980 Ling Tempco Vought of Dallas, Texas (now Lockheed Martin Missiles and Fire Control Dallas), was chosen as the prime contractor to coordinate the development of MLRS.

    first shells collected by the small-scale production were delivered in May 1982. Combat vehicles, collected in primary production were put into the army in August 1982. Were performed by an investment of over 42 million U.S. dollars to build automated manufacturing facilities located in East Camden (Arkansas), in which production takes place units (combat vehicles) and shells.

    In 1983, a new multiple rocket launcher MLRS began to come into service at the U.S. Army. After 2-3 years it has become by the armed land forces armies of other states.

    second multiyear contract for the purchase of MLRS system for years 1989-1993 was signed in July 1989. In 1989 fiscal year began joint production system MLRS experts USA, UK, Germany, France and Italy. As of September 1995 were put 857 combat vehicles - 772 in the army and 185 in the National Guard USA. Organizational systems are summarized in the MLRS battery and field artillery battalions. In Division and the Army Corps are respectively 9 and 27 military vehicles. According to others, they are deployed in a number of three in the battery and 29 in the division.

    One of the available photos 80s suggests that also offers the option of fighting machine with one TPK crawler.

    Composition

    multiple rocket launcher mlrs Initially the MLRS MLRS included:

    Fighting Vehicle M270 (stowed side view, front view);

    unguided projectiles (NURS) 227mm caliber in transport-launch containers;

    Transport-loading machine (see photo);

    communication and control systems.

    two main parts are fighting vehicle chassis and M270 artillery unit. BM M270 artillery unit is mounted on a modified elongated crawler infantry fighting vehicle M2 Bradley (load carrier M993). Through the use of this combat vehicle chassis is capable of driving on rough terrain, comparable with the same potential for M-1 tank. Chassis BM M270 is equipped with eight-cylinder diesel engine Cummins VTA-903 turbocharged power of 500 hp. s. The engine is located under the cab that can be folded forward to provide access to its sites. Transmission "General Electric" three-speed hydromechanical HMPT. Suspension torsion plate, with three independent shock absorbers on each side. Be cut off torsion suspension first, fifth and sixth rollers using multiple disc friction devices to provide the necessary stiffness support combat vehicle on the ground with a volley.

    cab chassis combat vehicle equipped with M270 (see wiring diagram):

    board positioning system that requires regular artillery topographic data, and through which the calculation of numbers determine their location.

    computerized fire control system that requires data on the target location and weather data in the target area for the calculation of the flight task and automated input of the various amendments after each shot. It includes: remote control with monitor and navigation system (topoprivyazchik);

    automated control system for targeting, which helps in automatic adjustment of tilt installation aimed coordinate system to determine the angles of the horizontal guidance and declination angles.

    sealing system, insulation and heating as well as a filtering unit designed to protect the rooms from the calculation of weapons of mass destruction.

    Cab protected from small arms and machine-gun fire and shell fragments of aluminum alloy armor, bulletproof glass when shooting close armored shutters.

    Artillery unit comprises a fixed base with a rotating frame, mounted on the chassis and body gyrostabilized rotating platform attached to her starting the charging module (PZM) M269, as well as guidance mechanisms in elevation and horizontal with elektrogidroprivodami. The composition of TZM M269 (see photo) includes armored box-farm under two transport-launch container reloading mechanism. Horizontal guidance mechanism is mounted on a stationary base. Structurally it is designed in one unit, and includes a level with the working fluid, a motor, hydraulic pump and the hydraulic servo motor. Vertical guidance mechanism is mounted on a rotating frame. Linkage starting charging unit formed as two paired screws actuated by pairs of bevel gears. These pairs of driving gears are rotatably driven hydraulic motor or manual drive (the latter is used in case of failure of the main drive).

    reloading mechanism consists of two sliding console with electric winches. Management can be implemented individually or together directly from the cockpit combat vehicle or using the keypad. TPK holder for charging PZM mounted in a horizontal position, the console reloading mechanism are put forward. Lifting transport and launch container by means of a winch, an exciting device which is attached to the center of gravity of the container (see photo). Once inserted into the clip TPK, he descends to the locating pins and locks into firing position with three clamping jaws. Each seat also has a manual locking mechanism to hold the WPK, crank which is at the bottom front of the nest. After fixation, the WPK and the connection of the electrical cable from the fire control system is automatically disconnected winches loading mechanisms.

    Loading the launcher carried kitted transport and launch container disposable. TPK loaded with rockets and sealed at the factory. Standard transport and launch canisters, which are also storage containers weigh 2270 kg and include six of fiber glass tubes, rigidly collar made of aluminum alloy. Inside the guide has spiral metal guides of NURS rotation to give a frequency of 10-12 rev / min with the shot to ensure the sustainability of the projectile in flight and eccentricity compensation traction. Start shells carried out directly from removable containers. Rockets can be stored in such containers for 10 years, being ready to use. For loading, aiming and a volley of 12 shells takes five minutes.

    fighting vehicle can be prepared to transport the plane Air Force C-141 on a limited basis, as well as Air Force aircraft C-5 and C-17. Payment consists of the commander and the rooms: the driver, operator guidance. However launches projectiles can be produced in two rooms of calculation, and in extreme cases - one number calculation.

    considering options towed launcher system MLRS (see diagram).

    In 90-ies of XX century was performed combat vehicle modernization, and its new model received the designation M270A1 (see layout scheme). The main directions of modernization of equipment were BM improved fire control system with the ability to display video information, a full keyboard, a memory for storing programs 1GB, improved mechanical system and modern navigation equipment GPS. This ensures a more rapid preparation to fire fighting vehicle, reducing reload time by 38%, reducing the cost of operation and maintenance. When performing a typical combat mission using combat vehicle M270A1 time required to accomplish it six times less than the time required when using BM M270. The machine has a built-in diagnostic system for timely failure detection. Modernization of BM to the U.S. Army M270 M270A1 version began in 2002.

    Usually, to serve one fighting machine uses two freight-loading vehicle with trailers. TPM is a 10-ton all-terrain vehicle M985 (8x8). His body is mounted 2.5-ton crane lifting and turning, through which the loading and unloading of containers. By car and trailer carrying four TPK (six missiles each). Ammunition Ammo one launcher, including its 12 missiles, is respectively 108 NUR.

    After the introduction of fire-control equipment for firing installations (including response time fuze head) PU guidance provided by the team using electrohydraulic actuators. Gorizontirovat launcher before firing is not required because the necessary amendments are continuously fed into the fire control equipment. It is provided with an appropriate system of gyro-stabilized platform. This system provides the necessary accuracy and in salvo firing.

    In ammunition

    MLRS MLRS includes the following types of unguided missiles:

    M26 with a range of 32 km.

    M26A1/A2 with a range of 45 km.

    M28 for anti-mining with a range of 40 km.

    trainer M28A1 (RRPR) with a range of up to 14.3 km.

    Consortium enterprises USA, Germany, UK and France development work HM29 projectile with submunitions equipped with a self-guided submunitions (SNBE). HM29 options worked for equipping the head of three or six SNBE BAT SNBE SADARM. According to the developers of the projectile HM29 prototype was successfully tested against the T-72 tank. Weight warhead with SNBE was 111 kg.

    In early 1987, argued that to equip NURS MLRS MLRS developed binary chemical warhead - HM135. Originally planned her arrival in 1991, but the procedure was delayed because of budgetary and political factors. Current state of development is unknown.

    Since the late 80-ies of the works on the new types of missiles with extended range, some samples of which have already been used in combat. They belong to the class of controlled and equipped with inertial guidance unit, based on the Global Positioning System GPS and small aerodynamic control surfaces that give effect to the overall increase in maneuverability and accuracy (see photo). In 2006, the pulsed power was demonstrated trajectory correction (see photo © Miroslav Gyurosi) for projectile system MLRS.

    Projectile M30 GMLRS (Guided MLRS) with a maximum range of 70 km (see diagram). M30 GMLRS development began in 1987.

    guided missiles XM30 GUMLRS (Guided Unitary MLRS) with a range of up to 70 km. Development projectile GUMLRS conducted by "Lockheed Martin" in cooperation with the firms UK, Germany, France and Italy in October 2003 missile tests were conducted at the site "White Sands" from 2004 to 2005 XM30 is equipped with high-explosive warhead undetached penetrating type (weight up to 89 kg) and is intended for destruction of protected objects of military-industrial infrastructure of the enemy (fortifications, runways, bridges, dams, warehouses, communication centers, etc.). The head part is equipped with a fuse with three settings that give effect to undermine in the air, at a meeting with the barrier and the undermining of a slowdown after penetrating the target. Caliber 227 mm, length - 4000 m, shell weight - 308 kg. For fire fighting vehicles can be used M270 and M270A1 MLRS MLRS M142 MLRS BM and HIMARS. First GUMLRS 498 shells were supplied to the U.S. Army in 2005. July 10, 2006 the company "General Dynamics Ordnance and Tactical Systems" was chosen by representatives of the U.S. Army and the company "Lockheed Martin" as a producer for the head of the projectile GUMLRS. The contract provides for delivery until 2020. Planned date of receipt of the troops was GUMLRS 2007.

    In 2008, Lockheed Martin announced the testing projectile GMLRS extended range, which hit a target located at a distance of 85 km from the starting point. According to a press release, the company Lockheed Martin from November 5, 2009, its experts on missile range White Sands carried out a successful launch of the projectile GMLRS, which amounted to a maximum range of 92 km. Start projectile was done with the help of the combat vehicle MLRS HIMARS. It is worth noting that there is no information about the tactics application of guided missiles. It is not clear whether the problem is solved their salvo start with the identification of each projectile its purpose or use of such shells implies a departure from the salvo firing.

    Work continues on improving the combat equipment shells. For example, modification of the GMLRS Unitary EBW is equipped with high-explosive fragmentation warhead effects due to excess pressure and is designed for use in urban environments.

    There is also information about Guided Missiles GMLRS Unitary.

    March 28, 2008 in a press release the company Lockheed Martin has been reported about the first four guided missiles start using a new universal fire control system, which is an evolutionary unit with the ability to upgrade the fire control system MLRS MLRS and enables firing guided missiles in Interference-proof design which used technology.

    December 13, 2010 the company Lockheed Martin announced the successful testing at the landfill White Sands (New Mexico pcs) guided missile GMLRS +, equipped with semi-active laser seeker.

    tests and operation

    MLRS Multiple rocket launchers were widely used by multinational forces in 1991. against Iraq during Operation "Desert Storm". At Kuwaiti theater of war American troops delivered 189 military vehicles. They were released on NURS 9600 targets such as artillery positions, the positions of defense, the accumulation of armor and automotive equipment, manpower enemy helicopters landing sites. According to others, during "Operation Desert Storm" the United States deployed more than 230 combat vehicles, Army UK - 16 MB.

    It should be noted that during these hostilities of the first combat vehicles MLRS MLRS was held shooting new tactical ballistic missiles of the U.S. Army ATACMS. Especially for firing the missiles were upgraded three batteries - 27 combat vehicles. However, details are not reported, in particular, the possibility of using the same chassis for mounting TPK firing shells of various calibres, since there is the view that on the same chassis platform chassis of the same type can be mounted only one TPK with shells caliber.

    fighting showed that was the only system MLRS Field Artillery USA, able to work in conjunction with tanks Abrams, BMP Bradley, as well as tactical assault aircraft, receiving from her targeting. As disadvantages MLRS members fighting noted a relatively small range of fire Nursi and what M77 bomblets were virtually ineffective against Iraqi armored targets.

    system was deployed by the U.S. Army in Albania for a potential combat support military operations in the Balkans.

    In 2007, Britain has deployed several combat vehicles MLRS M270 MLRS in Afghanistan. According to the command of the multinational NATO forces use guided missiles with GPS-guided provides hitting targets "with stunning precision".
