Leclerc tank

Leclerc tank
The Leclerc is a third-generation French main battle tank developed and manufactured by Nexter Systems. It was named in honour of Marshal Philippe Leclerc de Hauteclocque, a commander of the Free French Forces, who led the 2nd Armoured Division in World War II.
The Leclerc is in service with the French Army, Jordanian Army and the United Arab Emirates Army. In production since 1991, the Leclerc entered French service in 1992, replacing the AMX-30 as the country's main armoured platform. With production now complete, the French operate 222 Leclercs (with 184 more in storage, for a total of 406), while the United Arab Emirates (UAE) possesses 388.
Of the units in French service, 200 will be upgraded to the Leclerc XLR standard with deliveries expected to begin in 2022.
History
In 1964, studies were initiated about a possible replacement vehicle for the AMX-30 main battle tank: the Engin Principal Prospectif. In 1971, in view of the inferiority of the AMX-30 in comparison to the new generation of Soviet tanks about to be introduced, the Direction des Armements Terrestres ordered the beginning of the Char Futur project. In 1975, a working committee was created, and in 1977 it agreed on a list of specifications. In February 1980 however, a Memorandum of Understanding was signed with West Germany involving the joint development of a MBT, called the Napoléon I in France and Kampfpanzer III in Germany. Fundamental disagreements about its desired configuration led to a failure of this cooperation in December 1982. It was announced that a purely French battle tank would be developed, called "EPC" (Engin Principal de Combat). The importation of foreign equipment, like the M1 Abrams, the Leopard 2, or the Merkava, had been studied and rejected.
In contrast to most Western programmes of the time, more emphasis was placed on active than passive protection to limit overall vehicle mass. Mobility for evading enemy fire and fire control systems were given particular attention. Nevertheless, it was a stated design goal to achieve at least double the protection against KE-penetrators in comparison to the level attained in then-current MBTs of the fifty-ton weight class, the latter indicated at about 400 mm RHA equivalency. The higher level of protection would also protect against shaped charges.
Partnership with a foreign state was sought to limit unit cost, and found when the UAE ordered 436 vehicles, adding to the 426 units already planned for the French Army.
In 1986, the project was started under the name "Leclerc", and six prototypes were swiftly built. Mass production started in 1990 with the four-unit Batch 1, used mainly for comparative tests in foreign countries. The 17 units of Batch 2 shipped with turret and hull armour improvements, but were diagnosed with engine and suspension problems and quickly retired. Batch 3 followed with further improvements and used to define the doctrine of use as well as instruction. Batches 4 and 5 were better built, eliminating recurring powerplant problems, and are still in service after having been refitted in the late 1990s.
The second series started with Batch 6, with an added climate control system in the right rear of the turret. Batch 7 introduced a transmission system to the command vehicle, and a data system giving instantaneous vision of the state of all battle tanks and acquired targets. It also incorporated minor improvements in the visor. Batch 8 units had a modernised electronic system, and Batch 9 replaced the ATHOS thermal imaging with a SAGEM Iris providing better resolution.
In 2003, the Greek army sought to acquire a new tank and tested the T-80U, T-84, Leclerc, M1A2 Abrams, Challenger 2E and Leopard 2A5. The Leclerc received a perfect score at the firing range, with 20 rounds fired from 1500 and at 2000 m away. Its hunter-kill test performance was weaker, with the Leclerc scoring 13 out of 20, compared with 17 for the Leopard. Both the Leclerc and Leopard sustained a nine-round-per-minute firing rate, higher than those of the other tanks. The Leclerc achieved a 500 km range, higher than the others. But price tags seemed to be a determining factor and the Greek Army selected the Leopard.
All previous Leclerc batches were to be modernised to Batch 9 standards as of 2005. In 2004, Batch 10 was presented, incorporating a new armor package and information systems that could share the location of enemy and friendly units with all vehicles on the battlefield. This was the beginning of the 96-unit third series. By 2007, 355 tanks were to have been operational, 320 of them incorporated in four regiments, each with 80 Leclercs.
, after a French defence review, each of the four regiments operated 60 Leclerc tanks for a total of 240 in operational units; with a further 100 in combat ready reserve. Due to financial cuts, only 254 tanks were fully operational in 2011.
Main Ground Combat System
In 2015, Nexter Systems merged with German Krauss-Maffei Wegmann (KMW), maker of the Leopard 2 tank, to form KMW+Nexter Defense Systems (KNDS), and the German Ministry of Defence announced plans to develop a new tank jointly with France as a successor to both the Leopard 2 and Leclerc tanks, named Main Ground Combat System (MGCS). At the 2018 Eurosatory, KNDS presented a technology demonstrator tank combining the hull of a Leopard 2A7 with the lighter, two-man turret of a Leclerc.
System architecture definition and technology demonstration phase was to be completed by 2024, with production and testing to start in 2028.
UAE bribery allegation
In September 2018, Der Spiegel reported that an intermediary in the $3 billion-plus UAE tank sale was paid a commission of nearly US$200 million, and that part of the sum may have been used to bribe government officials.
Design
Armament
Primary
The Leclerc is armed with a 120 mm version F1 smoothbore gun designed by the arsenal of Bourges (EFAB) under the designation of CN120-26. Its barrel is 52 calibres long instead of the 44 calibre common on most main battle tanks of its generation, giving the projectile a higher muzzle velocity.
The Modèle F1 is compatible with 120x570mm NATO ammunition. This gun features a magnesium alloy thermal sleeve and an automatic loading mechanism. Elevation (+20°), depression (-8°), and turret traverse (360°) are electrically powered. The Leclerc EMAT used by the French Army relies on compartment overpressure for barrel fume extraction while the UAE tropicalized Leclerc uses a compressed-air fume extraction system.
Autoloader
Located inside the turret bustle, the autoloader is designated CHA ("automatic loading") and was designed by Creusot-Loire Industrie. The autoloader itself weighs 500 kg (empty) and has a total volume of 1.68 m (1.40 × 2.40 × 0.50 m). In case of ammunition cooking off, the deflagration is vented by two blow-out panels.
The autoloader allows the reloading of the gun while firing on the move, providing it a sufficient rate of fire to deal with six targets in one minute. The nominal firing sequence is below 8 seconds and the repetition rate (loading two ammunition of the same type one after another) is below 6 seconds. The autoloader is managed by a TM Motorola 68021 microprocessor.
The autoloader consists of a continuous link carrier magazine made of 22 cells and a rammer assembly. It can accommodate all types of ammunition that are to the NATO standard. Up to six different types of ammunition can be selected.
The cell positions the selected round for loading. At the same time, the main gun is decoupled from the stabilization system, indexed to 1.8° elevation and locked in alignment with the loading gutter. Then, a telescopic rammer pushes the round from the cell into the gun breech via a fiberglass gutter. After loading, the weapon is automatically driven back to the specified angle in accordance with the fire control system.
In case of power outage, the conveyor can be put into motion by using a hand-cranked electric generator.
The ammunition is normally inserted in the autoloader through a port in the rear wall of the turret bustle. A control panel allows the autoloader cells to be rotated to present a new empty cell. Two barcode readers identify the introduced ammunition in order to manage its position in the conveyor at any time. If the ammunition does not have a barcode, its type is entered through the control keyboard. It is possible to replenish the autoloader under armor, through a port in the inner bulkhead by using the 18 rounds cylinder located to the right of the driver's position.
Secondary
The Leclerc is also equipped with a 12.7 mm coaxial M2 heavy machine gun and a turret-mounted 7.62 mm machine gun, whereas most other NATO tanks use 7.62 mm weapons for both their coaxial and top machine gun mounts; the major exception is the American M1 Abrams, which has a 7.62 mm coaxial machine gun and two top-mounted machine guns, one 7.62 mm and one 12.7 mm.
Fire control and observation
The last 96 MBT XL Leclerc tanks have the ICONE TIS battle management system with digital communication system which integrates data from other tanks and upper levels of command. Since 2009, all the Leclerc tanks in service (S2 and SXXI) have ICONE BMS.
The digital fire control system can be operated independently by the gunner or the commander, and it offers real time integrated imaging from all of the tank's sensors and sights, including the gunner's SAVAN 20 stabilised sight, developed by SAGEM.
The Leclerc tank features the HL 60 gunner's primary sight from SAGEM. The sight has two day channels; a direct one with ×3.3 and ×10 magnification (×14 in case of the UAE version) and a video channel with ×10 magnification. The thermal channel offers ×3 and ×10 magnifications.
The Athos thermal imager has a detection range of 5000 m, can recognize targets at 2500 m and identify them at 2000 m. The laser range finder is of the Nd:YAG type. No emergency or auxiliary sights are mounted.
The tank commander can observe the surroundings through 7 episcopes and the SFIM HL 70 stabilized panoramic sight. The HL 70 is equipped with a day channel at ×2.5 and ×10 magnification and a night channel with ×2.5 magnification.
The UAE tropicalized Leclerc uses the improved HL 80 panoramic sight which features an electronic zoom ×2 and a laser range finder of the Nd:YAG type. The image intensifier is replaced by an Alis thermal imager.
The Leclerc SXXI uses the HL 120 panoramic sight that incorporates an Iris thermal imager.
Both sights are also equipped with a semi-auto tracker for target acquisition. The combination of the gunner's primary sight and commander's panoramic sight allows the Leclerc to operate in a hunter-killer mode.
Protection
Thermal signature
A feature of the Hyperbar system used by the V8X1500 engine is that it does not emit visible smoke during acceleration, allowing to reduce the infrared signature of the tank.
The exhaust temperature of the TM-307B gas turbine never exceeds 370°, whatever the engine speed.
Ballistic
The AMX-APX armament institution was responsible for the studies related to the configuration and the integration of the new ballistic protection concepts.
Original protection requirements were sent by the EPC project manager to AMX-APX on February 8, 1980. The protection of the future French main battle tank must guarantee a certain degree of invulnerability against 125 mm APFSDS and 130 mm shaped-charges warheads over its frontal arc. The whole fighting compartment must be protected against RPG-7 warheads and all-around protection should be provided against threats such as 30 mm autocannons.
Stéphane Ferrard (1947-2015), a military historian and French journalist, stated in his book, "The Leclerc System", that:
The turret and the hull are made of welded steel plates with a thickness ranging from 30 mm to 50 mm on which removable composite armor modules are mounted. Twelve modules surround the turret (six per side); they are numbered 1 to 6, starting from the front end. The modules are covered by an anti-slip coating made of fiberglass.
The turret bustle that contains the autoloader is protected on both sides against 30 mm armor-piercing rounds and shoulder-fired anti-tank weapon such as the RPG-7.
The composite storage boxes around and on the turret play a triple role: carrying the tool set, reducing radar cross-section and acting as spaced armor.
Structural self-sealing fuel tanks are located to the right forward part of the hull, in front and above the ammunition drum. Six heavy ballistic side skirts protect the front third of the hull sides; each is made of a composite panel covered by a steel outer shell.
SXXI
At the end of 1990s, a study was initiated to protect the Leclerc tank against the latest threats. These included ATGMs with tandem shaped-charge warheads capable of penetrating more than 1000 mm of RHA steel, as well as long-rod APFSDS with a length-to-diameter ratio of 30:1 with penetration performance exceeding 700 mm of RHA.
The technical approach consisted of replacing the passive composite modules protecting both sides of the turret bustle with lighter, reactive modules, incorporating semi-reactive layers. This weight-saving measure allowed the use of titanium in the ballistic protection of the turret frontal arc. It also shifted the center of gravity towards the front of the turret, closer to the traverse axis, facilitating the dynamic laying of the turret drives.
Block 10 and 11 (T10 and T11) Leclerc SXXI tanks are recognizable by their add-on ceramic armor plates bolted on the top of the reactive modules, protecting both sides of the autoloader compartment.
Passive counter-measures
Fourteen 80 mm dispensers of the Lacroix GALIX self-defence system are mounted onto the rear part of the turret. The French Army uses four types of ammunition:
Galix 3: three smoke grenades creating an opaque screen in the visual range for 50 seconds
Galix 4: two fragmentation grenades
Galix 6: one infrared decoy with a burn time of 10 seconds
Galix 13: three smoke grenades creating an opaque screen in the visual and infrared ranges for 30 seconds
Propulsion
The Leclerc has an eight-cylinder SACM (now Wärtsilä) V8X-1500 1,500 hp Hyperbar diesel engine and a SESM (now Renk AG) automatic transmission, with five forward and two reverse gears. The official maximum speed by road is 71 km/h and 55 km/h cross country (speeds in excess of 80 km/h were reported on road). The maximum range is given as 550 km, and can be extended to 650 km with removable external tanks. The "hyperbar" system integrates a small Turbomeca TM 307B gas turbine in the engine, acting both as a turbocharger and an APU giving auxiliary power to all systems when the main engine is shut down. The Hyperbar name comes from the unusually high boost pressure of 7.5 bar and the resulting mean effective pressure of 32.1 bar. For comparison, the turbocharged diesel engine in a typical passenger car has a mean effective pressure of about 20 bar. In addition, with boost available even when idling, this arrangement also works as an antilag system.
With a combat weight of 56 tons, the Leclerc is one of the lighter main battle tanks in the world, though still considerably heavier than Soviet and later Russian designs; this gives it one of the best power-to-weight ratios among Western tanks (27 hp per ton) and makes it one of the fastest MBTs of its generation (0 to 32 km/h in 5 seconds).
The engine exhaust, exiting at the rear left, is cooled to reduce the thermal signature of the Leclerc. Transmission is hydromechanical, with five forward and two reverse gears. Fuel tanks carry 1,300 litres and act as extra protection for the tank; two 200-litre external tanks can be fitted on the rear of the hull, though they have to be jettisoned before entering combat because they limit turret rotation.
The gearbox is equipped with a hydrokinetic retarder, which can slow the Leclerc down at a deceleration rate of 7 m/s2 (0.7 g) which is automatically used over 30 km/h.
Operational history
The four regiments which operate the Leclerc are:
1e régiment de chasseurs stationed near Verdun, part of the 7th Armoured Brigade
4e régiment de dragons stationed in Carnoux-en-Provence, part of the 7th Armoured Brigade
12e régiment de cuirassiers stationed in Olivet, part of the 2nd Armoured Brigade
501e régiment de chars de combat stationed in Mourmelon-le-Grand, 2nd Armoured Brigade
In service since 1992 (after the Persian Gulf War), the Leclerc has mostly seen deployment in low-intensity conflicts, including 15 Leclerc stationed in Kosovo (KFOR) and 13 others deployed in south Lebanon until 2010 for the UNIFIL peacekeeping operations, during which their performance was judged satisfactory by French officials.
As of August 2015, Leclerc tanks of the UAE were deployed in combat operations in Yemen (near Aden) as part of the Saudi-led coalition. It is estimated that 70 Leclerc MBTs were deployed by the UAE in Yemen, 15 of them equipped with the AZUR package. During one month, three tanks were damaged, two by antitank mines and one by an RPG, which damaged the grid without piercing the hull. One of the episcopes was hit by a ATGM, possibly of Konkurs or Konkurs-M type, killing the driver and injuring the commander's legs. None of these tanks were completely destroyed.
During the Iron Spear exercise, October 2019, Leclerc tanks crewed by the Lynx 6 Tactical Inter-Service Sub-Group (S-GTIA) participated in an inter-alliance exercise and surpassed the American M1A2 Abrams, German, Spanish and Norwegian Leopard 2s, Italian C1 Ariete and Polish PT-91.
As part of Mission Aigle, Leclerc tanks of the 1st Chasseur Regiment, 7th Armoured Brigade were deployed to Romania in November 2022. Currently, there are 13 tanks deployed with the Battle Group Forward Presence.

Proposed concept
Leclerc PTG (Poseur de Travure du Génie): proposed bridgelayer variant developed in 1996, no prototypes were built.
Leclerc 'Flakpanzer' SPAAG: Early 1990s proposal of a Leclerc fitted with a turret derived from that of the German Flakpanzer Gepard. It was imagined as armed with twin 35 mm Oerlikon KDA autocannons and two twin pack Mistral SAM launchers (total of four ready missiles). It was not adopted for service due to post-Cold War defence cutbacks.
Leclerc Crotale: A proposal from the same time period to fit the Crotale NG SAM system to a Leclerc chassis. Intended primarily to protect armored formations on the move against aerial attack. Again not proceeded with due to cutbacks. No prototype known to have been built.
Leclerc Koufra, or Leclerc T40: A proposal from the late 2000s to convert existing Séries 1 vehicles into a 'heavy' reconnaissance scout, primarily for urban warfare. The conversion included a brand new turret incorporating a CTA CT40 Case Telescoped Weapon System (CTWS) as well as grenade launchers, along with provision for two side-mounted anti-tank missiles.
Classified manual leak
In October 2021, in an attempt to improve the capabilities and accuracy of the vehicle's implementation in the war simulation game War Thunder, a crewman allegedly leaked excerpts of the tank's classified manual on the game's official forums. Forum moderators quickly removed the documents from their website, stating that they could not use the said classified documents due to legal problems that would ensue.
A similar incident had occurred in July 2021, when excerpts of the Challenger 2 tank's Army Equipment Support Publication (i.e. user manual), containing technical specifications of the vehicle, were posted on the official forums of the game by a UK tank commander, in a similar attempt to improve the capabilities and accuracy of the vehicle in the video game.
