  Leopard  

The first batch of Leopard tanks were built between September 1965 - July 1966, replacing the M47 within the German division of 1st Corps. The tank had an all-welded hull. Gunners primary sight is the Turmentfernungs-messer (TEM) 1A rangefinder sight (with 1720 mm basis length), linked to the unstabilised 105 mm British made L7A3 main gun.

 



Leopard 1 is modified several times from 1965 to 1995, bringing it to a modern standard today. The only backdraft is the thin armor and the small 105 mm main gun.

  Leopard 1A1  

A modernisation programme was launched in 1970 to enhance the combat effectiveness of the Bundeswehr's exisitng fleet. Most importantly, all Leopards received the hydraulic Cadillac-Gage main gun stabilisation system. This featured power-elevation and full stabilisation in both elevation and traverse. Targets could now be acquired and engaged on the move. The barrel of the main gun was equipped with a thermal sleeve to make the barrel temperature more stable. Metal-rubber side skirts were added to increase protection against HEAT shaped charges. New Diehl D640A double-pin tracks. For winter operations, a number of the detachable rubber pads could be replaced by special "X"-patterned metal pads (grousers). The IR (active) night sights for the driver and commander were replaced by passive image intensification night sights. This series of upgrades increased the combat weight to 41.5 tonnes.

From 1974 to 1977 all vehicles in the 1st to 4th batches, known as Leopard 1A1, were retrofitted with additional turret armor developed by Blohm und Voss. The add-on armor increased combat weight to 42.5 tonnes. Following modification, the vehicle was re-designated Leopard 1A1A1.

Leopard 1A1A2 received the PZB 200 from the Leopard 2 in 1980. This was because the Leopard 2 was fitted with thermal sights instead. The PZB 200 is a passive image intensification night vision system for aiming and observation. It consists mainly of the low-light-level television (LLLTV) camera, mounted on the gun mantlet in a pretective bar-shaped housing to the right-hand side of the vehicle's centreline. The system intensifies the night scene and transfer the image to TV monitor viewed by the gunner and/or commander. The Leopard 1A2 and A3 was also fitted with this system.

The Leopard 1A1A3 was fitted with the digital SEM80/90 VHF radio.

  Leopard 1A2  

Built 1972-1974, the 5th batch included 232 tanks with a cast steel turret of thicker armor. Designated Leopard 1A2, this tank is quite difficult to distinguish from the modernised Leopard 1A1 vehicles og the 4th batch, the former having oval (instead of circular) cover plates on the heads of its optical rangefinders. The Leopard 1A2 never received add on turret armor, but it did get an improved NBC protection system. Most vehicles from this batch saw service with the German 6th Panzer grenadier Division, which trained extensively with the Danish Army. The combat weight was 42.5 tonnes.

Leopard 1A2A1 received the PZB 200 from the Leopard 2 in 1980 along with the A1 and A3.

  Leopard 1A3  

The remaining 110 vehicles of the 5th batch were fitted with a new welded turret incorporating spaced armor and a wedge-shaped gun mantlet. Althoug the degree of armor protection remained unchanged, the internal volume of the turret was increased by 1.2 m². The improved TRP 2A independent sight was installed for the commander. The majority of this version Leopard went to the German 10th and 12th Panzer Divisions. Fahrgestell Nr- for the Leopard 1A2/A3 are 14001-14999. The combat weight was 42.5 tonnes.

  Leopard 1A4  

The Bundeswehr took delivery of the first 250 vehicles from the 6th batch in 1974, designated Leopard 1A4. This version had the welded turret introduced with the Leopard 1A3, but with new integrated fire control system. This comprised the PERI R12 stabilised independent sight for the commander, and the EMES 12A1 stereoscopic rangefinder and gunner's primary sight coupled to the fully stabilised main gun, controlled by a ballastic computer. The optical head of the PERI R12 is installed immediately in front of the commander's cupola on the turret roof. Installation of the fire control system used up additional space and consequently the ammunition load was reduced to 55 rounds, of which 42 were stored in the magazine to the left of the driver.

A new designation was prepared for the Leopard 1A4, but it was phased out before receiving the PZB 200 and SEM80/90 radios.

 

 

  Leopard 1A5  

In 1980 a research programme was undertaken to study further improvements to the Leopard 1, the aim being to maintain its survuvability and combat effectiveness beyond the year 2000. The tank was originally designed to combat the hordes of Soviet T-55 and T-62's, but now faced the more modern and formidable T-64B, T-72B, and T-72M1. The expected T-80B posed an even greater threat; the Leopard 1 would now have to operate effectively at night and poor visibility as well as shoot quickly and accurately on the move. Accordingly, a new thermal sight and fire control/ballistic computer fro the 105 mm main gun would be needed so as to ensure good penetration performance against increasingly sophisitcated Soviet armor.

After comparative trials, in December 1983 the Krupp-Atlas Electronik EMES 18 fire control system was selected. It was planned to convert 1,225 Leopard 1A1A1, re-designeted Leopard 1A5. The first modified vehicle was delivered to the Bundeswehr in early 1987.

The EMES 18 fire control system was developed from the proved EMES 15 installed in the Leopard 2. At its heart is the Hauptzielfernrohr (HZF) or primary sight, the optical block of which is installed in an armored housing on top of the turret to the right-hand side. This housing contains the thermal imaging system (made by Carl Zeiss) for target observation and acquisition at nigh or in bad weather, optical sighting lenses, as well as the laser rangefinder. The sights are viewed throug a 45° mounted movable gyro stabilized mirror. Two flaps provide protection when the sight or rangefinder is not in use. It is possible to view through a small hole in the right flap. The TEM 2A stereoscopic sight was removed, the resultant apertures on the turret sides being sealed with circular armored plates.

The ballistic computer is installed below the commander's seat on the bottom base plate of the turret. Derived from the one used in Leopard 2. The system stores ballistic information for up to seven different types of ammunition and is able to compute targeting solution out to 4000 m. The Danes fires their Leopard at a greater range, using hand help calculators to compute the sighting point. A built-in test/fault system locates any malfunctioning components. The computer control panel, installed above the gunner's seat, is common to Leopard 2.

The commander's TRP independent sight was retained, but is slightly taller for a clear view over the housing of the EMES 18. The original telescope (TZF 1A) for the gunner remained unchanged as a back up sight. A muzzle reference system was introduced, a Carl Zeiss colliminator being fitted at the end of the barrel for the gunner to rapidly check the adjustment of the HZF primary sight and main gun. The new SRK (Steuer und Regelkonzept) servo-hydraulic turret control system became available during the Leopard 1A5 conversion programme. From 1988, those vehicles already converted and delivered with the existing Cadillac-Gage system were retrofitted with the SRK. The Norwegian Leopard A5NO and A5NO2 were fitted with an all-electric turret control system with no hydraulic parts.

A crucial part of the Leopard 1upgrade was the introduction of more effective main gun ammunition, specifically APFSDS (armor piercing fin stabilized discarding sabot) rounds with advanced armor penetration material.

The running gears was also further improved with the addition of strengthened torsion bar suspension and shock absorber mointings. Other details changes included fitting hookeyes to vehicles in the 1st and 2nd batches and adding a cleaning system for the driver's vision blocks.

The Leopard 1A5A1 was fitted with the digital SEM80/90 VHF radio.

Interestingly, a single Leopard 1A5 was fitted with a Rheinmetall 120 mm smooth-bore gun for trials purposes. Althoug successful (all Leopard 1A5 being adapted to carry the weapon), plans to retrofit the 120 mm gun were eventually abandoned as being too impractical. The project ended in 1987. Note the additional armor mounted on the turret.

  Giat Industries new turret  

France's Giat Industries has teamed with DMD of the Slovak Republic to explore the feasibility of designing a low-profile turret armed with Giat's 120mm smoothbore gun and autoloader, developed for the Leclerc, to provide a cost-effective modernisation package for older main battle tanks (MBTs).

The proposed T-21 turret is intended for installation on T-72 series MBTs, therefore replacing the Soviet-built 125mm gun, and older Western MBTs such as the M60 and the Leopard 1, which are armed with 105mm guns. The T-21 weighs 15 tons compared to 18 tons for the Leclerc turret.

Compared to the Leclerc's autoloader, which carries 22 120mm rounds, the T-21 would carry 18 rounds. Another compromise would be a reduced level of armour protection, as at 15 tons it is not possible to guarantee 360° protection against hollow-charge warheads and protection against kinetic-energy rounds on the frontal arc. To limit weight, frontal protection has been reduced.

The fire-control system is a derivative of that of the Leclerc, as are many other components, while the electronic system is of the open architecture type, allowing easy interfacing with countermeasure and battlefield management systems chosen by the customer.

"We are able to provide nations that have numerous tanks with good chassis and outdated turrets with a modern tank that cost a fraction of that of a new MBT with 120mm armament," said a Giat source. Cost reduction is also linked to maintaining existing logistical support for the chassis, and retaining support equipment such as recovery vehicles and bridgelayers. (Source: Giat)
