Description

Leopard 1A2 The first 232 tanks of the fifth production batch were delivered as the Leopard 1A2 between 1972 and 1974. The A2 included a heavier and better armored turret, and therefore did not receive the B&V armor add-ons as did the earlier machines. However, they did receive the other upgrades; the Leopard 1A2A1 received the PZB 200, the Leopard 1A2A2 received digital radios, and the Leopard 1A2A3 got both. The Leopard (or Leopard 1) is a main battle tank designed and produced by Porsche in West Germany that first entered service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armor of limited value, the Leopard focused on firepower in the form of the German-built version of the British L7 105-mm gun, and improved cross-country performance that was unmatched by other designs of the era. The design started as a collaborative project during the 1950s between West Germany and France, and later joined by Italy, but the partnership ended shortly after and the final design was ordered by the Bundeswehr, with full-scale production starting in 1965. In total, 6,485 Leopard tanks have been built, of which 4,744 were battle tanks and 1,741 were utility and anti-aircraft variants, not including 80 prototypes and pre-series vehicles. The Leopard quickly became a standard of European forces, and eventually served as the main battle tank in over a dozen countries worldwide, with West Germany, Italy and the Netherlands being the largest operators until their retirement. Since 1990, the Leopard 1 has gradually been relegated to secondary roles in most armies. In the German Army, the Leopard 1 was completely phased out in 2003 by the Leopard 2, while Leopard 1-based vehicles are still widely used in utility roles. The Leopard 2 has replaced the Leopard 1 in service with many other nations as well, with derived vehicles using the Leopard 1 hull still seeing service. Currently, the largest operators are Greece, with 520 vehicles, Turkey, with 397 vehicles and Brazil with 378 vehicles. Most of these vehicles have been upgraded with various improvements to armor, firepower and sensors to maintain their ability to engage modern threats.

Variants

Leopard 1 The Leopard project started in November 1956 in order to develop a modern tank, the Standard-Panzer, to replace the Bundeswehr's American-built M47 and M48 Patton tanks, which, though just delivered to West Germany's recently reconstituted army, were rapidly becoming outdated. On 25 July 1957, the detailed specifications were released; the new design needed to weigh no more than 30 tons, have a power-to-weight ratio of 30 horsepower per ton, be able to withstand hits by 20 mm rapid-fire guns on every side as well as to operate in a battlefield contaminated with chemical weapons or radioactive fallout, the then-standard baseline for combat with the Warsaw Pact. In addition, the main armament had to consist of a 105 mm caliber weapon (the new British L7A3 105 mm gun was selected), carrying at least as many rounds as current US tank designs. Mobility had priority, while firepower came second; armor was seen as less essential, as it was believed that no real protection against hollow charge weapons was possible anyway.

Leopard 1A1 After the first batch was delivered, the next three batches were the Leopard 1A1 model, which included a new gun stabilization system from Cadillac Gage that allowed the tank to fire effectively on the move. The 1A1 also added the now-famous "skirts" along the sides to protect the upper tracks, and a new thermal jacket on the gun barrel to control heating. A less important change was to use rectangular rubber blocks fastened to the treads with a single pin instead of the earlier two-pin "shaped" versions. The rubber blocks could be easily replaced with metal X-shaped crampons for movement on ice and snow in the winter.

Leopard 1A2 The first 232 tanks of the fifth production batch were delivered as the Leopard 1A2 between 1972 and 1974. The A2 included a heavier and better armored turret, and therefore did not receive the B&V armor add-ons as did the earlier machines. However, they did receive the other upgrades; the Leopard 1A2A1 received the PZB 200, the Leopard 1A2A2 received digital radios, and the Leopard 1A2A3 got both.

Leopard 1A3 The next 110 vehicles in the fifth batch were fitted with a new welded turret, which was equipped with a new armor consisting of two spaced steel plates with a plastic filling between them (high-hardness armor, and a wedge-shaped gun mantlet, creating the Leopard 1A3. Although the level of armor area density was equivalent to the A2's new welded version, the internal volume was increased by 1.2 m³ and the effective protection level was increased by half. The improved TRP 2A independent sight was installed for the commander. Upgrades were identical to the 1A2 models, the Leopard 1A3A1 with the night sights, Leopard 1A3A2 with the new radios, and the Leopard 1A3A3 with both.

Leopard 1A4 The Leopard 1A4 formed the sixth batch of 250 vehicles, delivery starting in 1974. The 1A4 was externally similar to the 1A3, but included a new computerized fire control system and the new EMES 12A1 sighting system to aim it. In addition, the commander was provided with his own independent night sighting system, the PERI R12. The new equipment used up space and the ammunition load was reduced to 55 rounds, of which 42 were stored in the magazine to the left of the driver.

Leopard 1A5 In 1980, a research program was undertaken to study further improvements to the Leopard 1, providing it with a completely modern fire control system and fully effective night/bad-weather vision system. The decision was made to base the upgrades on the earlier models, which were no longer competitive. The resulting Leopard 1A5 was based on 1,225 vehicles of the Leopard 1A1A1 model. The turrets were again modified for the 1A5, both in order to store all of the new equipment, as well as to move more of the ammunition into the rear of the turret, as opposed to the left side of the driver where it had previously been stored. The new turret was also able to mount the newer 120 mm gun from the Leopard 2 if desired, although this option has not been used. After trials, the Krupp-Atlas Elektronik EMES 18 fire control system, which was developed from the EMES 15 used on the Leopard 2, was selected in December 1983. The EMES 18 included two new sights on the top of the turret, and no longer required the "bumps" as did the earlier optical systems. A crucial part of the upgrade was the introduction of more effective ammunition, including new APFSDS rounds. The Leopard tank could also be fitted with bolt-on polycarbonate (Lexan) armour panels, which have increased the effectiveness of the armour. The first modified vehicle was delivered in early 1987. Since then, almost all users of the Leopard 1 have also applied similar changes to their own vehicles, and in most ways the 1A5 be considered the "standard" Leopard 1 today. In the Netherlands, an improved version equivalent to the A5 called "Leopard 1 Verbeterd" (improved) was developed, the same version is used by the Chilean Army.

Leopard 1A6 The Leopard 1A6 prototype was a single Leopard 1 A1A1 testbed, modified with additional armor on the turret and equipped with a 120 mm L/44 gun. The project was ended in 1987, as the Leopard 2 was in widespread service at this point and the 1A5 offered a more reasonable upgrade path for a fraction of the cost.
