Panhard AML


The Panhard AML is an armoured car with reconnaissance capability. Designed by Panhard on a lightly armoured 4×4 chassis, it weighs an estimated 5.5 tonnes, and is thus suitable for airborne deployment. Since 1959, AMLs have been marketed on up to five continents; several variants remained in continuous production for half a century. These have been operated by fifty-four national governments and other entities worldwide, seeing regular combat.
The AML-245 was once regarded as one of the most heavily armed scout vehicles in service, fitted with a low velocity DEFA D921 90 mm rifled cannon firing conventional high explosive and high explosive anti-tank shells, or a 60 mm breech loading mortar with 53 rounds and dual 7.5mm MAS AA-52 NF-1 machine guns with 3,800 rounds, all mounted coaxially in the turret. An AML is capable of destroying targets at 1,500 meters with its D921 main gun. In this configuration it is considered a match for second-line and older main battle tanks.
AMLs have appeared most prominently in Angola, Iraq, and Chad, as well as in the Lebanese Civil War between 1975 and 1990.

History

During World War II, the French Army and their Free French successors used a wide variety of vehicles for reconnaissance duties, ranging from the compact Laffly S15 to the Panhard 178, which could mount the same 75 mm armament as contemporary heavy tanks, and multi-wheeled designs such as the Type 201. After the war it became less desirable to maintain this plethora of armoured cars. In July 1945 Paris issued a requirement for a postwar design combining those features of previous assets – especially the Type 201 – that had shown potential both during and prior to the Battle of France. This led to the 8x8 Panhard EBR which entered service in 1950. Similarly, in 1956 the French Ministry of Defense was persuaded to commission a replacement for the Daimler Ferret scout car. Also manufactured by Panhard, the successor was the AML which entered service in 1961.
As with much postwar hardware based on the experience of subsequent colonial theatres, the AML was recognized for its outstanding ruggedness, dependability, firepower-to-weight ratio, and adaptability to the numerous minor conflicts waged since 1945. This reputation has led to export success in over forty countries, Africa being one of its biggest markets.

Development

The Panhard AML was birthed as a private venture by the Société de Constructions Panhard et Levassor, a military subsidiary of PSA Peugeot Citroën. It was derived in part from the Daimler Ferret, offering important similarities in external design. The first prototype appeared in 1959 and the vehicle was put into production in 1960, with more than 4,000 examples constructed by the time production ended.
In the late 1950s, the French Army successfully operated a number of Ferret scout cars in Algeria. Impressive as they were from a conventional standpoint, the rest of France's existing light armour—such as the Panhard EBR and M8 Greyhound—were not suitably equipped for counter-insurgency; battles of the Algerian War often involved short, sharp, skirmishes which required indirect fire support weapons such as mortars rather than solid shot and shell. In addition, the North African conditions demanded a lighter, less sophisticated, vehicle which would be simpler to maintain and operate. As an interim measure France had purchased two hundred Ferrets from the United Kingdom. These were light enough but carried only a single general-purpose machine gun, which was inadequate for offensive purposes. Nevertheless, they were sufficiently successful that there was a possibility of producing the Ferret under licence in France. However, Saviem, Berliet, and Panhard petitioned for bidding on a home-grown vehicle, and in 1956 the Ministère de la Défense issued specifications for an indigenous wheeled armoured car of similar dimensions and layout to the Ferret but mounting a breech-loading mortar. By 1959, this had emerged as the Auto Mitrailleuse Légère, designated Model 245 "B" by Panhard. Early prototypes were completed in mid-1959 and by the end of 1961 at least one regiment in Algeria was receiving them. The AML was equipped with a 60mm Brandt gun-mortar and two medium MAS AA-52 NF-1 machine guns. Until Panhard's acquisition by Citroën later in the 1960s, it was manufactured at a single plant near the Porte de Choisy in the 13th arrondissement of Paris.
The AML was immediately successful, but as the Algerian conflict diminished so did the need for a light mortar carrier deployed in anti-guerrilla operations. A more primary concern was the conventional threat posed by Soviet airborne armoured vehicles such as the ASU-85 in the event of a Warsaw Pact invasion by air, which was then a major concern of French military strategists. Meanwhile, South Africa, an AML customer which had considered adopting the British Alvis Saladin, also charged Panhard technicians to look into the development of an AML variant with equal or superior fire support capability. This and the adoption of a highly effective 90 mm rifled cannon led to all new AML-245 "C"s being refitted with the H-90 turret sporting the new gun. It fired fin-stabilised, shaped charge, projectiles boasting a muzzle velocity of 760 m/s and more than capable of penetrating 320 mm of rolled homogeneous armour. In consequence, the later AMLs could even engage main battle tanks. In addition to its high explosive anti-tank shells the H-90 also carries fin-stabilised high-explosive projectiles, the total number of rounds stored being 20, compared with the 53 of the original 60 mm mortar version.
To provide a complete family of wheeled armoured cars, Panhard used AML components to engineer a small personnel carrier, the Véhicule Transport de Troupes, better known as the Panhard M3. The M3 consisted of a boxy, all-welded, hull with an engine relocated behind the driver in order to provide a large troop compartment at its rear. Its wheelbase was also increased from the AML's 2.5m to a higher 2.7m. and the track from 1.62 to 2.5m. In spite of this, maintenance alongside the AML fleet is rather simplified, given that both vehicles share a 95% interchangeability in automotive parts. The export success of the AML and M3 led directly to the development of the Panhard ERC 90 Sagaie and Panhard VCR, respectively, which were six-wheeled and could carry a wider range of heavy weapon systems.
Mass production of the AML likely ceased at some point prior to the early 1980s. However, AMLs continued to be sold from French Army surplus stocks as late as 1999, when the final export orders were placed by Yemen and Tunisia. They were also marketed by a number of other second-hand suppliers, including South Africa, Israel, and Saudi Arabia.

Specifications

Fitted with coil spring suspension and drum brakes, the AML lacks hydraulic assist on either brakes or steering; only front wheels steer. Consequently, the steering wheel requires considerable strength to turn while the vehicle is in motion—while stationary it remains effectively locked. Much like the Ferret, rear wheel drive is transmitted directly to epicyclic hub reduction gears, also known as bevel boxes. The motor and gearbox have been harnessed via a centrifugal clutch with electromagnetic control, eliminating the need for a clutch pedal. This type of clutch is automatically engaged by gripping the knob of the gearshift lever, which is located behind the driver's seat in the hull floor. The gearbox assembly consists of two separate gearboxes, one for high and the other for low gear. The low-range gearbox is designed for off-road use and has a reverse gear and a top gear, while the high-range box is for operation on roads and has three low gears and one overdrive. There is a hydraulic dual-circuit handbrake operating on the gearbox output shaft.
An AML's crankshaft is carried in three ball bearings to reduce motor friction. Powerplant design was inspired by the Panhard EBR and incorporates an air-cooled 1.99 litre four cylinder engine developing 67 kW. The Panhard engine was somewhat underpowered for the five to six tonne armoured car, and remained prone to mechanical failure in humid climates. Under temperate conditions it was capable of providing good operational service up to 26,000 kilometres before needing replacement. AMLs may also be fitted with a variety of liquid-cooled engines, although as demonstrated by its Eland Mk7 counterpart this requires a costly reconstruction of the rear hull to accommodate the new cooling apparatus.
AML hulls are assembled from only 13 welded pieces, with a driver seated at the front of the hull and the turret to his immediate rear. Above both doors the hull widens into a circular flange onto which the turret is bolted. This makes the turret basket extremely cramped, and little space is available above an AML-90's turret ring due to the massive gun breech and somewhat haphazard ammunition stowage. There are optical ring sights in front of both turret seats for quick laying of the main armament. AML turrets have a two-man crew, with the commander seated on the left and the gunner on the right. Depending on the variant, either may operate the roof-mounted searchlight. Seven periscopes are provided for the turret crew and three for the AML's driver. One of the three driving periscopes may be substituted with an infrared or image intensification periscope for night operations.
On either side of the hull below the turret ring is an access door, one for the driver on the right and one intended for emergency purposes on the left. The left hull door, on which a spare wheel and tyre or fuel cans may be mounted, opens to the rear while the right hull door opens to the front. The engine housing at the rear of the hull is accessed through two access panels, and is insulated from the crew compartment by a removable bulkhead. Two sand channels resembling those on the Ferret are bolted to the hull front for crossing ditches and other obstacles.
The AML uses nitrogen inner tubes adopted from the EBR, providing run flat capability on 41 cm -diameter wheels; its 280 mm wide Michelin tyres can be deflated to reduce ground pressure to as low as. These have been replaced in some Anglophone armies by the Dunlop Trak Grips also favoured in Bedford and Alvis military vehicles.
