The Leopard (or Leopard 1) is a main battle tank designed and produced in West Germany that first entered service in 1965. Developed in an era when HEAT warheads were thought to make conventional heavy armour 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. Since 1990, the Leopard 1 has gradually been relegated to secondary roles in most armies. In the German Army, the Leopard 1 MBTs were phased out in 2003, while Leopard 1 derived vehicles are still widely used. The Leopard 2 MBTs have taken over the MBT role. Leopard hulls have been re-used in a wide variety of roles.
Model:
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.
Between 1974 and 1977, all of the machines in the first four batches were brought to the same Leopard 1A1A1 standard, and given additional turret armor developed by Blohm & Voss. A further upgrade in the 1980s added leftover image-intensifier night sights, which were being handed down from the Leopard 2 as they were themselves upgraded. The PZB 200 image intensification system was mounted in a large box on the upper right of the gun, creating the Leopard 1A1A2. A further upgrade with SEM80/90 all-digital radios created the Leopard 1A1A3. Later improvements to the image intensifier created the Leopard 1A1A4.
Leopard 1A2
The first 232 tanks of the fifth production batch was 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 armour 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 lexan armour panels, which have increased the effectiveness of the armour. These "modified" tanks have proved themselves in the field.
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 can be considered the "standard" Leopard 1 today.
Leopard 1A6
A single 1A1A1 was also modified with additional armor on the turret and had the 120 mm gun as the Leopard 1A6. The project was ended in 1987, as the Leopard 2 was in widespread service at this point and the 1A5 offered a reasonable upgrade path for a fraction of the cost.
