The AMX Leclerc, is a main battle tank (MBT) built by GIAT, now Nexter of France. It was named in honour of General Philippe Leclerc de Hauteclocque who led the French element of the drive towards Paris while in command of the Free French 2nd Armoured Division (2ème DB) in World War II.

The Leclerc is in service with the French Army and the army of the United Arab Emirates. In production since 1991,[1] the Leclerc entered French service in 1992,[1] replacing the venerable AMX 30 as the country's main armoured platform. With production now complete, the French Army has a total of 406 Leclercs and the United Arab Emirates Army has 388. The current price in 2011 is €9.3 million, making it the most expensive tank in history.[5]

History[edit]

In 1964 studies were initiated about a possible replacement vehicle for the AMX 30: 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 that in 1977 agreed on a list of specifications. In February 1980 however, a Memorandum of Understanding was signed with the Federal Republic of 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). Importation of foreign equipment, like the M1 Abrams, the Leopard 2, or the Merkava had been studied and rejected.[6]

In contrast to most Western programmes of the time, much consideration was given to active, besides passive protection, to limit the overall mass of the vehicle. 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 at the same time protecting against shaped charges.[7]

Partnership with a foreign state was sought to limit the cost per unit, and this was found when the United Arab Emirates ordered 436 vehicles, adding to the 426 units already planned for the French Army.

In 1986, the project was started under the name of "Leclerc", six prototypes being built swiftly. 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 were shipped, with improvements in the turret and in the hull armour. These units were diagnosed with problems in the engine and suspension, and were quickly retired. Batch 3 followed with some improvements and have been used to define the doctrine of use, and instruction.

Batches 4 and 5 were better built, eliminating the recurrent problems in the powerplant, and are still in service, after having been refitted at the end of the 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 was a modernisation of the electronic system, and Batch 9 replaced the thermal imaging ATHOS by a SAGEM Iris with better resolution.

All previous batches will be modernised up to the standards of Batch 9 from 2005. In 2004, Batch 10 was presented, incorporating new information systems which could share the disposition of enemy and friendly units to all vehicles on the battlefield, and a new armor package. This was the beginning of the 96-unit third series. By 2007, 355 tanks should have been operational, 320 of them incorporated in four regiments, each of 80 Leclerc vehicles.

As of 2010, after a French defence review, each of the four regiments operates 60 Leclerc tanks for a total of 240 in operational units; with a further 100 Leclerc in combat ready reserve. Due to finance cuts, only 254 tanks are fully operational in 2011.[5]

The four regiments are:

Design[edit]

Armament[edit]

Note the commander's sight on the right and gunner's sight on the left side of the picture.

The Leclerc is equipped with a GIAT (Nexter) CN120-26 120mm smoothbore cannon. This cannon is capable of firing the same NATO standard 120mm rounds as the German Leopard 2 and US M1 Abrams, but in practice only French-produced ammunition is issued. The gun is insulated with a thermal sleeve and has an automatic compressed-air fume extraction system instead of the usual bore evacuator. The Leclerc has a unique autoloading system which was specifically designed for it, and reduces the crew to three by eliminating the human loader. The turret of the Leclerc was designed around the auto-loading system in order to avoid the problems common to other tanks with an autoloader. The Leclerc autoloader allows a rate of fire of 12 shots per minute and holds 22 rounds of ready ammunition; it can accommodate up to six different types of ammunition at once, although like most autoloader systems it cannot change ammunition types once a round has been loaded. The most common types are the armour piercing fin-stabilised discarding sabot (APFSDS) with a tungsten core and the high explosive anti-tank (HEAT) round. There are 18 other rounds available for reload. A Leclerc tank can fire while traveling at a speed of 50 km/h on a target 4,000 metres away[citation needed]. The gun is 52 calibres long instead of the 44 calibres common on most tanks of the Leclerc's generation,[1] giving the rounds a higher muzzle velocity.

The Leclerc is also equipped with a 12.7 mm coaxial machine gun and a remote-controlled 7.62mm machine gun, whereas most other NATO tanks use 7.62mm weapons for both their coaxial and top machine gun mounts; the major exception is the American M1 Abrams, which has a 7.62mm coaxial machine gun and two top-mounted machine guns, one 7.62mm and one 12.7mm.

Protection[edit]

The Leclerc has the GALIX combat vehicle protection system from GIAT, which fires a variety of smoke grenades and infra red screening rounds, as well as anti-personnel grenades.

The hull and the turret are made of welded steel fitted with modular armour, which can be replaced easily for repair or upgraded over the years. The French army in the late seventies rejected Chobham armour as being overly specialised in its optimisation to defeat hollow charge-weapons; it therefore opted to develop their own composite arrangement to defeat both hollow charge and sabot round. Due to the introduction of modernized threats, the batch 3 has a new armour package, including composite armor, titanium insert and on the sides of the turret, ERA blocks.

Fire control and observation[edit]

The last 96 AMX XL Leclerc 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 Leclerc in service (S2 and SXXI have ICONE BMS)

The Leclerc tank features the HL-60 gunners primary sight from SAGEM. The sights day channel offers X3.3 and X10 magnification (x14 in case of the UAE version). The night channel thermal intensifier offers X3, X6, X10 and X20 magnifications. No emergency or auxiliary sights are mounted. The laser range finder is of the Nd:YAG type at 1.06 µm. The tank commander can observe the surroundings through 7 periscopes and the HL-70 Panoramic sight. The HL-70 is equipped with a day channel at X2.5 and X10 magnification and a night channel with X2.5 magnification. On the Series XXI and UAE variant the HL-80 commanders panoramic sight is mounted. The sight offers X2.5 and X10 magnification (and an electronic zoom X2) for the thermal intensifier and a laser range finder of the Nd:YAG type at 1.06 µm. Both sights are also equipped with a semi auto tracker for target acquisition. The combination of the gunners primary sight and commanders panoramic sight allows the Leclerc to operate in a hunter-killer mode.

The Leclerc's 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.

Propulsion[edit]

The Leclerc has an eight-cylinder SACM (now Wärtsilä) V8X-1500 1,500 hp Hyperbar diesel engine and a SESM ESM500[8] automatic transmission, with five forward and two reverse gears. The official maximum speed by road is 72 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 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.[9] To compare, the largest diesel engine in the world (the Wärtsila RTA96) has a mean effective pressure of 18.6 bar.[10] In addition, being the boost available even at idle, this arrangement also works as an anti-lag system.

At a combat weight of just 56 tons, the Leclerc is one of the lightest main battle tanks in the world; this gives it one of the best power-to-weight ratios among the Western tanks (27 hp per ton) and makes it one of the fastest MBTs of its generation (0 to 32 km/h under 6 seconds).

The engine exhaust, exiting at the rear left, is cooled to reduce the thermal signature of the tank. Transmission is a hydromechanical type with five forward and two reverse gears. Fuel tanks carry 1,300 litres and act as extra protection; two 200-litre external tanks can be fitted on the rear of the turret, but have to be jettisoned before entering combat since they limit turret rotation.

The gear box 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.

Combat experience[edit]

In service only since 1992 (after the Persian Gulf War), the Leclerc has no notable experience in true warzone environments, but has seen deployment on multiple low-intensity conflicts, including 15 Leclerc stationed in Kosovo (KFOR) and others in Lebanon (UNIFIL) in the context of UN peace-keeping operations, where their performance was judged satisfactory by French officials.

Until 2010, 13 Leclerc were deployed in the south Lebanon for a peacekeeping mission with UNIFIL.

    • EuroPowerPack with the MTU 883 diesel engine of 1,100 kW. The United Arab Emirates have interests in the German company which builds them (MTU) and preferred an engine of their own. This powerplant is more reliable than the French UDV 8X (1,100 kW), though it has small problems with the clutch[citation needed].
    • Externally mounted Diesel auxiliary power unit with a tank infantry telephone fitted on its armored box.
    • Redesigned engine compartment (louver, access panels).
    • Engine-driven mechanical air-conditioning mounted in the left part of the hull to cool the tank without the use of electric current which could reveal the position of the tank.
    • HL-80 commander panoramic sight with Alis thermal camera and laser rangefinder.
    • ATO (Armement Télé-Opéré) remote-controlled mount for a 7.62 mm FN MAG machine-gun operated under-armour by the HL-80 panoramic sight.
