102-575: The system is fully autonomous, the crew sitting in the cab, with similar performance to the PzH 2000, but with reduced cost, crew levels and weight. The AGM uses the PzH 2000 ballistic fire-control computer with integrated NATO Armaments Ballistic Kernel and the Krauss-Maffei Wegmann Artillery Command and Control System. It is a modular system, the gun module can be fitted on a tracked or wheeled chassis. Costs can be reduced by fitting it to

204-542: A GPS -aided inertial navigation system and extended range. Flight control is accomplished by four forward-mounted canards driven by electromechanical actuators. GMLRS rockets were introduced in 2005 and can be fired from the M270A1 and M270A2, the European M270A1 variants ( British Army M270B1, German Army MARS II, French Army Lance Roquette Unitaire (LRU), Italian Army MLRS Improved (MLRS-I), Finnish Army M270D1), and

306-433: A diesel engine ; modern technology, including the use of turbo-charging , helps to overcome the lower power-to-weight ratio of diesel engines compared to petrol. Gas turbine (turboshaft) engines offer a very high power-to-weight ratio and were starting to find favour in the late 20th century – however, they offer very poor fuel consumption and as such some armies are switching from gas turbines back to diesel engines (i.e.

408-447: A main battle tank will normally be designed to take hits from other tank guns and anti-tank missiles , whilst light reconnaissance vehicles are often only armoured "just in case". Whilst heavier armour provides better protection, it makes vehicles less mobile (for a given engine power), limits its air-transportability, increases cost, uses more fuel and may limit the places it can go – for example, many bridges may be unable to support

510-494: A turret or cupola. The greater the recoil of the weapon on an AFV, the larger the turret ring needs to be. A larger turret ring necessitates a larger vehicle. To avoid listing to the side, turrets on amphibious vehicles are usually located at the centre of the vehicle. Grenade launchers provide a versatile launch platform for a plethora of munitions including, smoke , phosphorus, tear gas , illumination, anti-personnel, infrared and radar-jamming rounds. Turret stabilization

612-726: A British Army engineer. They were very popular with smaller countries. Some saw some combat (with limited success) in World War II. However, the vulnerability of their light armour eventually caused the concept to be abandoned. However, the German Army uses a modern design of air-transportable armoured weapons carriers, the Wiesel AWC , which resembles the concept of a tankette. The term "super-heavy tank" has been used to describe armoured fighting vehicles of extreme size, generally over 75 tonnes. Programs have been initiated on several occasions with

714-565: A GMLRS rocket with a new cluster munition warhead developed under the Alternative Warhead Program (AWP), aimed at producing a drop-in replacement for DPICM bomblets in M30 guided rockets. It was fired by an M142 HIMARS and traveled 35 km (22 mi) before detonating. The AWP warhead will have equal or greater effect against materiel and personnel targets, while leaving no unexploded ordnance behind. In October 2013, Lockheed conducted

816-639: A July 2008 Department of Defense policy directive, issued under President George W. Bush, that US cluster munitions that leave more than 1% of submunitions as unexploded ordnance must be destroyed by the end of 2018. (The United States is not a party to the Convention on Cluster Munitions , which prohibits them). The last use of the M26 rocket prior to its use with the GLSDB occurred during Operation Iraqi Freedom in 2003. Guided multiple launch rocket system (GMLRS) rockets have

918-747: A Vickers QF-1 "Pom-Pom" gun of 40 mm. The Germans fielded the Sd.Kfz. 10/4 and 6/2, cargo halftracks mounting single 20 mm or 37 mm AA guns (respectively) by the start of the war. Rocket launchers such as the Soviet Katyusha originated in the late 1930s. The Wehrmacht fielded self-propelled rocket artillery in World War II – the Panzerwerfer and Wurfrahmen 40 equipped half-track armoured fighting vehicles. Many modern multiple rocket launchers are self propelled by either truck or tank chassis. The level of armour protection between AFVs varies greatly –

1020-766: A candidate for the Feux Longue Portée-Terre (FLP-T) or Land Long Range Fires procurement program, the Thundart guided artillery rocket is designed to have a range of 150 km and the ability to be fired from the French version of the M270, the Lance-Roquettes Unitaire (LRU). In April 2012, Lockheed Martin received a $ 79.4 million contract to develop a GMLRS incorporating an Alliant Techsystems -designed alternative warhead to replace DPICM cluster warheads. The AW version

1122-459: A cannon battalion over an hour to fire. In early February 1991, 4-27 FA launched the biggest MLRS night fire mission in history, firing 312 rockets in a single mission. When ground operations began on 24 February 1991, 414 rockets were fired as the U.S. VII Corps advanced. Out of the 57,000 artillery rounds fired by the end of the war, 6,000 were MLRS rockets plus 32 ATACMS. The MLRS has since been used in numerous military engagements, including

1224-563: A crew of two being seated in the fully armoured protected cab. A further development of the AGM was revealed in 2008 as the Donar 155 mm self-propelled artillery system. The system uses a modified ASCOD 2 IFV chassis with a newer, more efficient two-man turret with a fully automatic ammunition loading and handling system. This variant is known as the RCH-155 (Remote Controlled Howitzer). The development

1326-435: A highly mobile and protected fighting unit has been around for centuries; from Hannibal 's war elephants to Leonardo 's contraptions , military strategists endeavoured to maximize the mobility and survivability of their soldiers. Armoured fighting vehicles were not possible until internal combustion engines of sufficient power became available at the start of the 20th century. Modern armoured fighting vehicles represent

1428-488: A maximum range of about 90 km (56 mi). In 2009 Lockheed Martin announced that a GMLRS had been successfully test fired 92 km (57 mi). During the Russo-Ukrainian War , Russian forces have relied on electronic warfare to jam GPS signals. The inertial navigation system is immune to jamming, but less accurate than when paired with GPS coordinates and can miss the target. Ukraine attempted to mitigate

1530-471: A multi-mode fuse adding a proximity airburst mode for use against personnel in the open; proximity mode can be set for 3 or 10 meters (9.8 or 32.8 ft) Height of Burst (HOB). The GMLRS has a minimum engagement range of 15 km (9.3 mi) and can hit a target out to 70 km (43 mi), impacting at a speed of Mach 2.5. In 2009 Lockheed Martin announced that a GMLRS had been successfully test fired out to 92 km (57 mi). In April 2011,

1632-529: A number of platforms and countries. These include: M26 and M28 rocket production began in 1980. Until 2005 they were the only rockets available for the M270 system. When production of the M26 series ceased in 2001, a total of 506,718 rockets had been produced. Each rocket pod contains 6 identical rockets. The M26 rocket and its derivatives were removed from the US Army's active inventory in June 2009, as they did not satisfy

1734-542: A range of up to 300 kilometres (190 mi). Each rocket pod contains one ATACMS missile. As of 2022 only the M48, M57, and M57E1 remain in the US military's active inventory. The Precision Strike Missile (PrSM) is a new series of GPS-guided missiles, which will begin to replace ATACMS missiles from 2024. PrSM carries a newly designed area-effects warhead and has a range of 60–499 kilometres (37–310 mi). PrSM missiles can be launched from

1836-556: A reloading point, then move to a completely new hiding position near a different firing point. These shoot-and-scoot tactics were planned to avoid susceptibility to Soviet counter-battery fire. One M270 firing 12 M26 rockets would drop 7,728 bomblets, and one MLRS battery of nine launchers firing 108 rockets had the equivalent firepower of 33 battalions of cannon artillery. The system can fire rockets or MGM-140 ATACMS missiles, which are contained in interchangeable pods. Each pod contains six standard rockets or one guided ATACMS missile;

1938-467: A tank being first deployed as a medium tank, but in later years relegated to light tank roles. Tanks were also classified by roles that were independent of size, such as cavalry tank , cruiser tank , fast tank , infantry tank , "assault" tank, or "breakthrough" tank. Military theorists initially tended to assign tanks to traditional military infantry, cavalry, and artillery roles, but later developed more specialized roles unique to tanks. In modern use,

2040-414: A tank chassis. During World War II, most major military powers developed self-propelled artillery vehicles. These had guns mounted on a tracked chassis (often that of an obsolete or superseded tank) and provided an armoured superstructure to protect the gun and its crew. The first British design, "Bishop" , carried the 25 pdr gun-howitzer in an extemporised mounting on a tank chassis that severely limited

2142-702: A target area with large numbers of truck-mounted multiple rocket launchers (MRLs), such as the BM-21 "Grad" . By contrast, U.S. artillerists favored conventional large-caliber artillery for its relative accuracy and logistical efficiency. As a result, U.S. rocket artillery was limited to the remaining stock of World War II -era systems. This mindset began to change following the 1973 Yom Kippur War , which saw heavy casualties, especially from rear-area weapons like surface-to-air missiles (SAMs). Israel effectively employed rocket artillery against these targets. The United States predicted that this requirement would persist in

2244-630: A tracked variant of the Boxer that would be able to use all the weapon modules of the existing wheeled Boxer . Therefore it can become with a lot of ease one of the next tracked artillery system. In 2023, Switzerland selected 2 systems to compete for the replacement program of the M-109 ( "Artillerie Wirkplattform und Wirkmittel 2026" ), the RCH-155, and the BAE Archer . For the RCH-155, two platforms are offered by KNDS ,

2346-409: A user's suitable chassis of choice. Current development vehicles use a MLRS chassis. A vehicle independent auxiliary power unit (allowing the gun to be used with the carrier engine shut down) and an inertial reference unit with a Global Positioning System (GPS) connection are fitted. During trials in 2006, a demonstrator vehicle fired a volley of ten 155 mm rounds in 2 minutes and 19 seconds with

2448-446: A very large movable siege tower, the helepolis , as early as 340 BC, and Greek forces used such structures in the Siege of Rhodes (305 BC). The idea of a protected fighting vehicle has been known since antiquity. Frequently cited is Leonardo da Vinci 's 15th-century sketch of a mobile, protected gun-platform ; the drawings show a conical, wooden shelter with apertures for cannons around

2550-488: A wide variety of both ground targets and air targets. Despite significant advances in anti-tank warfare , it still remains the most versatile and fearsome land-based weapon-systems of the 21st-century, valued for its shock action and high survivability . A tankette is a tracked armed and armoured vehicle resembling a small "ultra-light tank" or "super-light tank" roughly the size of a car, mainly intended for light infantry support or scouting . Tankettes were introduced in

2652-463: Is a highly capable shoot and scoot system, and demonstrations have shown its capability to shoot at 360°, and even with some shooting in movement. All the Boxer can receive this module, but as it is a heavy vehicle, some modifications to bring it to the A3 chassis standard are required. And a remote weapons station with a .50 caliber machine gun can be fitted on the roof, but with a rather low profile to remain in

2754-616: Is a tank fulfilling the role of a main battle tank, but using only anti-tank surface-to-surface missiles for main armament. Several nations have experimented with prototypes, notably the Soviet Union during the tenure of Nikita Khrushchev (projects Object 167, Object 137Ml, Object 155Ml, Object 287, Object 775), A flame tank is an otherwise-standard tank equipped with a flamethrower , most commonly used to supplement combined arms attacks against fortifications , confined spaces, or other obstacles. The type only reached significant use in

2856-445: Is an armed combat vehicle protected by armour , generally combining operational mobility with offensive and defensive capabilities. AFVs can be wheeled or tracked . Examples of AFVs are tanks , armoured cars , assault guns , self-propelled artilleries , infantry fighting vehicles (IFV), and armoured personnel carriers (APC). Armoured fighting vehicles are classified according to their characteristics and intended role on

2958-430: Is an important capability because it enables firing on the move and prevents crew fatigue. Modern AFVs have primarily used either petrol (gasoline) or diesel piston engines. More recently, gas turbines have been used. Most early AFVs used petrol engines , as they offer a good power-to-weight ratio . However, they fell out of favour during World War II due to the flammability of the fuel. Most current AFVs are powered by

3060-457: Is caused to a large area while leaving behind only solid metal penetrators and inert rocket fragments from a 90 kilograms (200 lb) warhead containing approximately 182,000 preformed tungsten fragments. The unitary GMLRS also has an airburst option, but while it produces a large blast and pieces of shrapnel, the AW round's small pellets cover a larger area. In May 2013, Lockheed and ATK test fired

3162-420: Is designed as a drop-in replacement with little modification needed to existing rockets. An Engineering and Manufacturing Development (EMD) program was to last 36 months, with the alternative warhead GMLRS expected to enter service in late 2016. The AW warhead is a large airburst fragmentation warhead that explodes 30 ft (9.1 m) over a target area to disperse penetrating projectiles. Considerable damage

3264-426: Is distinguished by its high level of firepower, mobility and armour protection relative to other vehicles of its era. It can cross comparatively rough terrain at high speeds, but its heavy dependency on fuel, maintenance, and ammunition makes it logistically demanding. It has the heaviest armour of any AFVs on the battlefield, and carries a powerful precision-guided munition weapon systems that may be able to engage

3366-813: Is increased from 154 inches (390 cm) to 170.5 inches (433 cm). Originally called the Fighting Vehicle System, the M987 chassis was designed to serve as the basis for many other vehicles. These included the XM1070 Electronic Fighting Vehicle, the M4 Command and Control Vehicle, the Armored Treatment and Transport Vehicle and the Forward Area Armored Logistics System, the latter encompassing three vehicles, including

3468-685: The 2003 invasion of Iraq . In March 2007, the British Ministry of Defence decided to send a troop of MLRS to support ongoing operations in Afghanistan's southern province of Helmand , using newly developed guided munitions. In September 2005, the GMLRS was first used in Iraq, when two rockets were fired in Tal Afar over 50 kilometres (31 mi) and hit insurgent strongholds, killing 48 Iraqi fighters. During

3570-598: The 2023 Israel–Hamas war , Israel used the M270 for the first time since 2006, to fire on Hamas targets in the Gaza Strip . During the 2022 Russian invasion of Ukraine , the United States considered sending the MLRS as part of military aid to Ukraine. Concerns were raised that this system could be used to hit targets inside Russia. US President Joe Biden initially declined to send it to Ukraine, but on May 31 he announced that

3672-678: The Boxer and the Mowag Piranha IV 10×10 . As 132 Piranha IV will enter service of the Swiss Army from 2023 (48 " 12 cm Mörser 16  [ de ] " and 84 " PI PZ 21" combat engineer vehicle), the variant of the RCH-155 based on the Piranha IV is a likely winner. A design of such a vehicle exists. It is based on a 40t capable military truck which is already in use in the German Army. It keeps

3774-749: The Hussite Wars . These heavy wagons were given protective sides with firing slits; their heavy firepower came from either a cannon or from a force of hand-gunners and crossbowmen , supported by light cavalry and infantry using pikes and flails . Heavy arquebuses mounted on wagons were called arquebus à croc . These carried a ball of about 3.5 ounces (100 g). By the end of World War II , most modern armies had vehicles to carry infantry, artillery and anti-aircraft weaponry . Most modern AFVs are superficially similar in design to their World War II counterparts, but with significantly better armour, weapons, engines, electronics, and suspension. The increase in

3876-566: The M142 HIMARS , another vehicle capable of firing GMLRS rockets, would be supplied. On 7 June 2022, British defence secretary Ben Wallace announced that the UK would send three (later increased to six) MLRS to aid Ukrainian forces. On 15 June, Germany announced it would send three of its MARS vehicles from German Army stocks. Ukraine announced they had received the first M270s on 15 July. The German defence secretary Christine Lambrecht announced

3978-595: The MOWAG Piranha , originally designed as an APC, has been adapted to fill numerous roles such as a mortar carrier , infantry fighting vehicle, and assault gun. Armoured fighting vehicles began to appear in use in World War I with the armoured car, the tank, the self-propelled gun, and the personnel carrier seeing use. By World War II, armies had large numbers of AFVs, together with other vehicles to carry troops this permitted highly mobile manoeuvre warfare . The concept of

Modern main battle tanks or "universal tanks" incorporate recent advances in automotive, artillery, armour, and electronic technology to combine the best characteristics of the historic medium and heavy tanks into a single, all-around type. They are also the most expensive to mass-produce. A main battle tank

4182-476: The Second World War (1939–1945). The armoured personnel carrier, designed to transport infantry troops to the frontline, emerged towards the end of World War I. During the first actions with tanks , it had become clear that close contact with infantry was essential in order to secure ground won by the tanks. Troops on foot were vulnerable to enemy fire, but they could not be transported in the tank because of

4284-518: The Second World War , during which the United States, Soviet Union , Germany , Italy , Japan and the United Kingdom (including members of the British Commonwealth ) all produced flamethrower-equipped tanks. Usually, the flame projector replaced one of the tank's machineguns, however, some flame projectors replaced the tank's main gun. Fuel for the flame weapon was generally carried inside

4386-565: The "Menatetz", an upgraded version of the M270 MLRS. As part of the circa £2bn Land Deep Fires Programme (LDFP), the British Army intends a large scale modernization effort of its GMLRS capability involving both a increase in the number of launchers and an expansion in the variety of effectors available. The British Army launchers will be upgraded to the M270A2 standard and additional launchers will be purchased and upgraded from stockpiles likely from

4488-766: The 41st Field Artillery Brigade (Babenhausen) and 4/27th FA (MLRS) (Wertheim) deployed in support of Operation Desert Shield from their bases in Germany and 1/ 158th Field Artillery from the Oklahoma Army National Guard deployed in January 1991. MLRS launchers were deployed during Operation Desert Storm. Its first use was on 18 January 1991, when Battery A of the 6th Battalion, 27th Field Artillery fired eight ATACMS missiles at Iraqi SAM sites. In one engagement, three MLRS batteries fired 287 rockets at 24 separate targets in less than five minutes, an amount that would have taken

4590-513: The Army. The Army evaluated the MLRS prototypes from December 1979 – February 1980. In May 1980, the Army selected the Vought system. In early 1982, Vought began low-rate initial production. In August 1982, the first production models were delivered. In early 1983, the first units were delivered to the 1st Infantry Division . In March 1983, the first operational M270 battery was formed. In September 1983,

4692-505: The Battalion was the first U.S. Field Artillery unit to fire into Iraq. Over the course of the war, the 6th Battalion, 27th Field Artillery provided timely and accurate rocket and missile fires for both U.S. corps in the theater, the 82nd Airborne Division, the 6th French Light Armored Division, the 1st Armored, 1st Infantry Division, the 101st Airborne Division, and the 24th Infantry Division (Mechanized). A Battery 92nd Field Artillery (MLRS)

4794-564: The GSRS could be manufactured in Europe. This was to allow European nations, who had been independently pursuing their own MLRS programs, to buy in to the program. In July 1979, the United States, West Germany , France and the United Kingdom signed a memorandum of understanding for joint development and production of GSRS. In November 1979, GSRS was accordingly redesignated the multiple launch rocket system. Both competitors delivered three MLRS prototypes to

4896-725: The IDF had selected a development of the ATMOS 2000 instead, possibly because they preferred a wholly Israeli produced system for legal reasons. M270 Multiple Launch Rocket System The M270 Multiple Launch Rocket System ( M270 MLRS ) is an American armored self-propelled multiple launch rocket system . The U.S. Army variant of the M270 is based on the chassis of the Bradley Fighting Vehicle . The first M270s were delivered in 1983, and were adopted by several NATO and non-NATO militaries. The platform first saw service with

4998-638: The M270 MLRS Self-Propelled Loader/Launcher (SPLL). The SPLL is composed of two primary subsystems; the M269 Launcher-Loader Module (LLM) houses the electronic fire-control system and sits atop the M993 Carrier Vehicle. The M993 is the designation of the M987 carrier when it is used in the MLRS. The M987/M993 is a lengthened derivative of the Bradley Fighting Vehicle chassis, in which the ground contact length

5100-705: The M270A2 and the M142, with rockets pods containing 2 missiles. As of 2022 the PrSM is in low rate initial production with 110 missiles being delivered to the US military over the year. PrSM will enter operational service in 2023. In the Turkish SAGE-227 project A/B/C/D medium-range composite-fuel artillery rocket and SAGE-227 F experimental guided rocket were developed from reverse engineering HIMARS missiles due to trust issues in 2019. Israel developed its own rockets to be used in

5304-447: The M31 could hit targets accurately with less chance of collateral damage while needing fewer rockets to be fired, reducing logistical requirements. The unitary warhead also made the MLRS able to be used in urban environments. The M31 had a dual-mode fuse with point detonation and delay options to defeat soft targets and lightly fortified bunkers respectively, with the upgraded M31A1 equipped with

5406-543: The MLRS occurred in the Gulf War. The U.S. deployed over 230 MLRS during Operation Desert Storm, and the UK an additional 16. In September 1990, the 6th Battalion, 27th Field Artillery deployed to Saudi Arabia in support of Operation Desert Shield . Assigned to the XVIII Airborne Corps Artillery, the unit played a critical role in the early defense of Saudi Arabia. As Desert Shield turned into Desert Storm ,

5508-505: The Russian T-80 used a gas turbine engine, whereas the later T-90 does not). The US M1 Abrams is a notable example of a gas turbine powered tank. Notable armoured fighting vehicles extending from post-World War I to today. The tank is an all terrain AFV incorporating artillery which is designed to fill almost all battlefield roles and to engage enemy forces by the use of direct fire in

M270s provided by the United Kingdom have seen use in the Russian invasion of Ukraine . In the early 1970s, the Soviet Union had a clear advantage over U.S. and NATO forces in terms of rocket artillery. Soviet doctrine dictated large-scale bombardment of

5814-432: The XM1007 AFARV rearm vehicle. The original GSRS plan called for 210 mm diameter rockets. After European allies became involved with the project, these were replaced with 227 mm rockets in order to accommodate the AT2 mine . Cold War doctrine for the M270 called for the vehicles to spread out individually and hide until needed, then move to a firing position and launch their rockets, immediately move away to

5916-479: The aim of creating an invincible siegeworks / breakthrough vehicle for penetrating enemy formations and fortifications without fear of being destroyed in combat. Examples were designed in World War I and World War II (such as the Panzer VIII Maus ), along with a few in the Cold War . However, few working prototypes were built and there is no clear evidence any of these vehicles saw combat, as their immense size would have made most designs impractical. A missile tank

6018-420: The amount charged to the U.S. Army. According to the U.S. Army's budget, it will pay about $ 168,000 for each GMLRS in 2023. Both Lockheed Martin and the U.S. Army report that the GMLRS has a maximum range of 70+ km (43+ mi). According to a U.S. Department of Defense document the maximum demonstrated performance of a GMLRS is 84 km (52 mi), a figure also reported elsewhere. Another source reports

6120-510: The arrival of the vehicles they contributed on 26 July 2022, and on 15 September Lambrecht announced that Germany would transfer two more. During the Russo-Ukrainian War , Russian forces have relied on electronic warfare to jam GPS signals. The inertial navigation system is immune to jamming, but less accurate than when paired with GPS coordinates and can miss the target. The M270 system can fire MLRS Family of Munitions (MFOM) rockets and artillery missiles, which are manufactured and used by

6222-400: The battlefield. The classifications are not absolute; two countries may classify the same vehicle differently, and the criteria change over time. For example, relatively lightly armed armoured personnel carriers were largely superseded by infantry fighting vehicles with much heavier armament in a similar role. Successful designs are often adapted to a wide variety of applications. For example,

6324-404: The best technical approach for the GSRS. In March 1976, the Army awarded contracts to Boeing , Emerson Electric , Martin Marietta , Northrop and Vought to explore the concept definition of the GSRS. In September 1977, Boeing Aerospace and Vought were awarded contracts to develop prototypes of the GSRS. In 1978, the U.S. Army Aviation and Missile Command made changes to the program so that

6426-409: The bottom of the hull. Weaponry varies by a very wide degree between AFVs – lighter vehicles for infantry carrying, reconnaissance or specialist roles may have only a autocannon or machine gun (or no armament at all), whereas heavy self-propelled artillery will carry howitzers , mortars or rocket launchers. These weapons may be mounted on a pintle , affixed directly to the vehicle or placed in

6528-413: The capability to be used in direct hit fashion with optronics capabilities. It is equipped with a hydraulic compartment, and can receive an auxiliary power unit to power the turret and the electronic while keeping the engine of the truck off. The Artillery Gun Module was a potential choice for the Israel Defense Forces as they seek to replace the M109 in their service. However, in 2017, it appeared that

6630-425: The capacity of transport aircraft makes possible and practicable the transport of AFVs by air. Many armies are replacing some or all of their traditional heavy vehicles with lighter airmobile versions, often with wheels instead of tracks. The first modern AFVs were armed cars, dating back virtually to the invention of the motor car . The British inventor F. R. Simms designed and built the Motor Scout in 1898. It

6732-573: The circumference. The machine was to be mounted on four wheels which would be turned by the crew through a system of hand cranks and cage (or "lantern") gears . Leonardo claimed: "I will build armoured wagons which will be safe and invulnerable to enemy attacks. There will be no obstacle which it cannot overcome." Modern replicas have demonstrated that the human crew would have been able to move it over only short distances. Hussite forces in Bohemia developed war wagons – medieval horse-drawn wagons that doubled as wagon forts – around 1420 during

However, at a two percent dud rate, that would leave approximately 400 undetonated bombs scattered over the area, which could endanger friendly troops and civilians. Production of the M270 ended in 2003, when a last batch was delivered to the Egyptian Army . In 2003, the U.S. Army began low-rate production of the M142 HIMARS . The HIMARS fires all of

Thus, the need had arisen for a system that could engage enemy air defenses and provide counter-battery fire , freeing large-caliber artillery units to provide call-for-fire artillery support for ground forces. The MLRS was initially conceived as the General Support Rocket System (GSRS). In December 1975, the U.S. Army Missile Command issued a request for proposal to industry to assist in determining

7038-399: The first Self-propelled artillery , was fielded in 1917. It was based on the first tank, the British Mark I , and carried a heavy field-gun. The next major advance was the Birch gun (1925), developed for the British motorised warfare experimental brigade (the Experimental Mechanized Force ). This mounted a field gun, capable of the usual artillery trajectories and even anti-aircraft use, on

7140-400: The first modernized MLRS II and M31 GMLRS rocket were handed over to the German Army's Artillery School in Idar Oberstein. The German Army operates the M31 rocket up to a range of 90 kilometres (56 mi). A German developmental artillery system, called the Artillery Gun Module , has used the MLRS chassis on its developmental vehicles. In 2012, a contract was issued to improve the armor of

7242-401: The first unit was sent to West Germany. European nations produced 287 MLRS systems, with the first being delivered in 1989. Some 1,300 M270 systems have been manufactured in the United States and in Western Europe to date, along with more than 700,000 rockets of all kinds, including over 70,000 GMLRS guided munitions as of March 2024. The M270 MLRS weapons system is collectively known as

7344-438: The frontal assault role. Though several configurations have been tried, particularly in the early experimental "golden days" of tank development, a standard, mature design configuration has since emerged to a generally accepted pattern. This features a main tank gun or artillery gun , mounted in a fully rotating turret atop a tracked automotive hull, with various additional secondary weapon systems throughout. Philosophically,

7446-674: The gun's performance. It was replaced by the more effective Sexton . The Germans built many lightly armoured self-propelled anti-tank guns using captured French equipment (for example Marder I ), their own obsolete light tank chassis ( Marder II ), or ex-Czech chassis ( Marder III ). These led to better-protected tank destroyers, built on a medium-tank chassis such as the Jagdpanzer IV or the Jagdpanther . The Self-propelled anti-aircraft weapon debuted in WWI. The German 88  mm anti-aircraft gun

7548-400: The heavy tank has fallen out of favour, being supplanted by more heavily armed and armoured descendant of the medium tanks – the universal main battle tank . The light tank has, in many armies, lost favour to cheaper, faster, lighter armoured cars ; however, light tanks (or similar vehicles with other names) are still in service with a number of forces as reconnaissance vehicles , most notably

7650-494: The individual vehicle too, depending on the role of the vehicle and the likely direction of attack. For example, a main battle tank will usually have the heaviest armour on the hull front and the turret, lighter armour on the sides of the hull and the thinnest armour on the top and bottom of the tank. Other vehicles – such as the MRAP family – may be primarily armoured against the threat from IEDs and so will have heavy, sloped armour on

7752-505: The intense heat and noxious atmosphere. In 1917, Lieutenant G. J. Rackham was ordered to design an armoured vehicle that could fight and carry troops or supplies. The Mark IX tank was built by Armstrong, Whitworth & Co. , although just three vehicles had been finished at the time of the Armistice in November 1918, and only 34 were built in total. Different tank classifications emerged in

7854-765: The interwar period. The tankette was conceived as a mobile, two-man model, mainly intended for reconnaissance. In 1925, Sir John Carden and Vivian Loyd produced the first such design to be adopted – the Carden Loyd tankette . Tankettes saw use in the Royal Italian Army during the Italian invasion of Ethiopia (1935–1936), the Spanish Civil War (1936–1939), and almost everywhere Italian soldiers fought during World War II . The Imperial Japanese Army used tankettes for jungle warfare . The British Gun Carrier Mark I ,

7956-491: The jamming by changes to the software and attacking Russian jamming systems by artillery. The Ground Launched Small Diameter Bomb is a weapon made by Boeing and the Saab Group , who modified Boeing's GBU-39 Small Diameter Bomb (SDB) with the addition of a rocket motor. It has a range of up to 150 km (93 mi). The Army Tactical Missile System (ATACMS) is a series of 610 mm surface-to-surface missile (SSM) with

8058-434: The lighter M142 HIMARS launchers. M30 rockets have an area-effects warhead, while M31 rockets have a unitary warhead, but the rockets are otherwise identical. By December 2021, 50,000 GMLRS rockets had been produced, with yearly production then exceeding 9,000 rockets. Each rocket pod contains 6 identical rockets. The cost of an M31 missile is estimated at $ 500,000, though this may be the "export price", always higher than

8160-474: The mid-1920s as a reconnaissance vehicle and a mobile machine gun position They were one or two-man vehicles armed with a machine gun. Colloquially it may also simply mean a "small tank". Tankettes were designed and built by several nations between the 1920s and 1940s following the British Carden Loyd tankette which was a successful implementation of "one man tank" ideas from Giffard Le Quesne Martel ,

8262-507: The muddy, pocked terrain and slit trenches of the Battle of the Somme . The tank eventually proved highly successful and, as technology improved, it became a weapon that could cross large distances at much higher speeds than supporting infantry and artillery . The need to provide the units that would fight alongside the tank led to the development of a wide range of specialised AFVs, especially during

8364-496: The munitions of the MLRS, and is based on the chassis of the Family of Medium Tactical Vehicles . As of 2012, BAE Systems still had the capability to restart production of the MLRS. In 2006, MLRS was upgraded to fire 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

8466-484: The opposing force who can often hear and even feel their arrival. Tanks were classified either by size or by role. Classification by relative size was common, as this also tended to influence the tanks' role. Over time, tanks tended to be designed with heavier armour and weapons, increasing the weight of all tanks, so these classifications are relative to the average for the nation's tanks for any given period. An older tank design might be reclassified over time, such as

8568-443: The railroad loading gauges. As of 2019, firing trials with the turret traversed front and to its sides were carried out at WTD 41 proving ground. The trials demonstrated the ability to fire an 8-round burst and redeploy under 90 seconds, and carry out multi-round simultaneous impact missions. A variant of the Boxer for resupply has been designed. It enables the resupply of the artillery module without being outside. KMW designed

8670-527: The realization of an ancient concept – that of providing troops with mobile protection and firepower. Armies have deployed war machines and cavalries with rudimentary armour in battle for millennia. Use of these animals and engineering designs sought to achieve a balance between the conflicting paradoxical needs of mobility, firepower and protection. Siege engines , such as battering rams and siege towers , would often be armoured in order to protect their crews from enemy action. Polyidus of Thessaly developed

8772-641: The rocket's range to 150 km (93 mi). Later in March the ER GMLRS was fired out to 135 km (84 mi). In September 2023, Lockheed announced an ER GMLRS test achieved its maximum range of 150 km (93 mi). The U.S. Army approved the ER GMLRS for production in May 2024. When first deployed with the U.S. Army, the MLRS was used in a composite battalion consisting of two batteries of traditional artillery ( howitzers ) and one battery of MLRS SPLLs (self-propelled loader/launchers). The first operational Battery

8874-439: The tank is, by its very nature, an offensive weapon. Being a protective encasement with at least one gun position, it is essentially a pillbox or small fortress (though these are static fortifications of a purely defensive nature) that can move toward the enemy – hence its offensive utility. Psychologically, the tank is a force multiplier that has a positive morale effect on the infantry it accompanies. It also instills fear in

8976-597: The tank, although a few designs mounted the fuel externally, such as the armoured trailer used on the Churchill Crocodile . Flame tanks have been superseded by thermobaric weapons such as the Russian TOS-1 . The idea for this tank was developed during World War I by British and French. The infantry tank was designed to work in concert with infantry in the assault, moving mostly at a walking pace, and carrying heavy armour to survive defensive fire. Its main purpose

9078-698: The third and final engineering development test flight of the GMLRS alternative warhead. Three rockets were fired from 17 kilometers (11 mi) away and destroyed their ground targets. The Alternative Warhead Program then moved to production qualification testing. The fifth and final Production Qualification Test (PQT) for the AW GMLRS was conducted in April 2014, firing four rockets from a HIMARS at targets 65 kilometers (40 mi) away. Armoured fighting vehicle An armoured fighting vehicle ( British English ) or armored fighting vehicle ( American English ) ( AFV )

9180-435: The two types cannot be mixed. The LLM can hold two pods at a time, which are handloaded using an integrated winch system. All twelve rockets or two ATACMS missiles can be fired in under a minute. One launcher firing twelve rockets can completely blanket one square kilometre with cluster munitions ; a typical MLRS cluster salvo would involve three M270 vehicles firing together. With each rocket containing 644 M77 submunitions,

9282-475: The weight of a main battle tank. A trend toward composite armour is taking the place of steel – composites are stronger for a given weight, allowing the tank to be lighter for the same protection as steel armour, or better protected for the same weight. Armour is being supplemented with active protection systems on a number of vehicles, allowing the AFV to protect itself from incoming projectiles. The level of protection also usually varies considerably throughout

9384-445: Was C Battery, 3rd Battalion, 6th Field Artillery, 1st Infantry Division (Ft. Riley, Kansas) in 1982. The first operational organic or "all MLRS" unit was 6th Battalion, 27th Field Artillery . Originally, a battery consisted of three platoons with three launchers each for nine launchers per battery; by 1987, 25 MLRS batteries were in service. In the 1990s, a battery was reduced to six launchers. The 6th Battalion, 27th Field Artillery

9486-460: Was announced in April 2014, KMW decided to integrate the module onto the Boxer 8×8 armoured vehicle. The concept was shown at the Eurosatory weapon trade fair in June 2014. Contrary to all other wheeled artillery systems, the RCH-155 doesn't require an additional ground support to ensure the precision and the durability. It is stable enough as it is, and doesn't require hydraulic stabilisers. It

9588-509: Was deployed to the Gulf War in 1990 from Ft. Hood Texas. 3/27th FA (MLRS) out of Fort Bragg deployed in support of Operation Desert Shield in August 1990. A/ 21st Field Artillery (MLRS) – 1st Cavalry Division Artillery deployed in support of Operation Desert Shield in September 1990. In December 1990, A- 40th Field Artillery (MLRS) – 3rd Armored Division Artillery (Hanau), 1/27th FA (MLRS) part of

9690-442: Was equipped with a Hotchkiss machine gun , and with 7 mm armour for the gunner. Armoured cars were first used in large numbers on both sides during World War I as scouting vehicles. In 1903, H. G. Wells published the short story " The Land Ironclads ," positing indomitable war machines that would bring a new age of land warfare, the way steam-powered ironclad warships had ended the age of sail . Wells's literary vision

9792-591: Was powered by a four-cylinder 3.3-litre 16 hp Cannstatt Daimler engine giving it a maximum speed of around 9 miles per hour (14 kilometres per hour). The armament, consisting of two Maxim guns, was carried in two turrets with 360° traverse. Another early armoured car of the period was the French Charron, Girardot et Voigt 1902 , presented at the Salon de l'Automobile et du cycle in Brussels , on 8 March 1902. The vehicle

9894-529: Was quickly fielded and used in action in Iraq . Lockheed Martin also received a contract to convert existing M30 Dual-Purpose Improved Conventional Munition (DPICM) GMLRS rockets to the XM31 unitary variant. The M31 GMLRS Unitary rocket transformed the M270 into a point target artillery system for the first time. Due to Global Positioning System (GPS) guidance and a single 200 lb (91 kg) high-explosive warhead,

9996-589: Was reactivated as the Army's first MLRS battalion in October 1984, and became known as the "Rocket Busters". In March 1990, the unit deployed to White Sands Missile Range , New Mexico to conduct the Initial Operational Test and Evaluation of the Army Tactical Missile System. The success of the test provided the Army with a highly accurate, long range fire support asset. The first combat use of

10098-629: Was realized in 1916, when, amidst the pyrrhic standstill of the Great War , the British Landship Committee deployed revolutionary armoured vehicles to break the stalemate. The tank was envisioned as an armoured machine that could cross ground under fire from machine guns and reply with its own mounted machine guns and naval artillery . These first British tanks of World War I moved on caterpillar tracks that had substantially lower ground pressure than wheeled vehicles, enabling them to pass

10200-578: Was the first armed, petrol-engine powered vehicle ever built. It consisted of a De Dion-Bouton quadracycle with a Maxim machine gun mounted on the front bar. An iron shield offered some protection for the driver from the front, but it lacked all-around protective armour. The armoured car was the first modern fully armoured fighting vehicle. The first of these was the Simms's Motor War Car , also designed by Simms and built by Vickers, Sons & Maxim in 1899. The vehicle had Vickers armour 6 mm thick and

10302-499: Was to suppress enemy fire, crush obstacles such as barbed-wire entanglements, and protect the infantry on their advance into and through enemy lines by giving mobile overwatch and cover . The French Renault FT was the first iteration of this concept. The British and French retained the concept between the wars and into the Second World War era. Because infantry tanks did not need to be fast, they could carry heavy armour. One of

10404-646: Was truck-mounted and used to great effect against British tanks, and the British QF 3-inch 20 cwt was mounted on trucks for use on the Western Front . Although the Birch gun was a general purpose artillery piece on an armoured tracked chassis, it was capable of elevation for anti-aircraft use. Vickers Armstrong developed one of the first SPAAGs based on the chassis of the Mk.E 6-ton light tank/ Dragon Medium Mark IV tractor , mounting
