MBT Revolution by Rheinmetall

The Leopard 2 MBT Revolution is a former upgrade package, developed and manufactured by Rheinmetall for the Leopard 2A4 Tank. A number of sources confuse the Leopard 2 Evolution as the Leopard 2 MBT Revolution.

The  IBD Deisenroth Engineering Evolution, which only featured AMAP armor upgrades, was unveiled at the CANSEC 2009 show in Ottawa, Canada. The MBT Revolution was unveiled at Eurosatory 2010 and featured an AMAP Armor package and a new digital architecture.

Rheinmetall have since introduced a new version of the Leopard 2 Evolution, called “MBT Evolution“. The  Leopard 2 MBT Revolution package has also been improved and is now marketed as the “MBT Advanced Technology Demonstrator“. Source fighting-vehicles.com

By combining numerous individual components and measures, Rheinmetall created a comprehensive 360° protection concept that addresses virtually every current threat. Thanks to the use of highly advanced materials and technologies, the increase in weight is comparatively small. Further advantages include easy mounting and dismounting of the protective modules on the vehicle’s exterior; the need for structural alteration is negligible.

Modular in design, the protection package contains the following elements:

  • Lateral protection of turret and hull against IED blasts, including shrapnel resulting from the detonation of multiple artillery shells or large explosively formed projectiles.
  • Protection of the hull against large-calibre KE rounds, precision guided munitions and guided and unguided antitank weapons.
  • Protection of the roof against artillery bomblet fragments.
  • Protection of the turret against large-calibre KE rounds, precision guided munitions and guided and unguided antitank weapons.
  • Protection of the vehicle’s underside and interior from mine blasts.
  • Decoupled magazine
  • ROSY, Rheinmetall’s unique new smoke/obscurant system, provides 360° protection against TV-, EO-, IR-, IIR-, laser and SCALOS-guided weapons. Unlike conventional smoke/obscurant systems, ROSY not only generates an instantaneous multispectral interruption of the line of sight in less than 0.6 seconds, it also produces a dynamic wall of smoke/obscurant which provides moving vehicles with lasting protection from multiple attacks.

The Revolution main battle tank is better suited for urban warfare and low-intensity conflicts. It is worth noting that original Leopard 2 tanks were developed during the Cold War and were intended for high intensity conflicts based on tank battles in open terrain. The tank has improved overall protection. It is fitted with new Advanced Modular Armor Protection (AMAP) composite armor package. It uses new nano-ceramics materials and modern titanium and steel alloys. This armor provides higher level of protection against wide range of threats. The AMAP armor can be done is different compositions and armor configuration depends on customer requirements. Various configurations do different jobs. Some are used for RPG attacks, the other are used for IED attacks.

AMAP composite armor

Advanced Modular Armor Protection (AMAP)

The MBT Revolution has a new Advanced Modular Armor Protection (AMAP) upgrade, which contains the various passive AMAP composite armor offered by Rheinmetall Chempro GmbH. The modular armor extends the length of the turret and most of the hull for improved protection in built-up/urban area’s. The rear section of the hull is fitted with cage armor. Source fighting-vehicles.com

The tank is also fitted with a mine protection package. This MBT has a modular armor, so damaged modules can be easily replaced in field conditions. Tank is also fitted with new Rheinmetall ROSY smoke grenade dischargers. These set up a smoke screen within 0.6 seconds. Overall the Revolution MBT is less vulnerable to ambushes, RPG rounds, anti-tank missiles, improvised explosive devices and mines.

ROSY smoke screen system

The unique 40mm Rosy_L smoke protection system offers light military and civilian vehicles protection from unexpected attacks, e.g. during patrols or when travelling in convoys. Unlike the conventional smoke protection systems in use, Rosy_L is able to generate dynamic smoke screens as well as spontaneous, large-area and multispectral interruption of the line of sight (LOS). Moreover, its multimission capability represents a sure defence against stream and wave attacks. Due to its integrated IR jamming and decoying capabilities, Rosy_L effectively counters all TV-, EO-, IR-, IIR-, laser- and SACLOS-guided weapons. Rosy_L comprises a basic system with a control device and one to four ROSY launchers per vehicle. By means of a one-click adapter, the system can be quickly mounted to the vehicle without tools, and just as quickly removed and stowed.

The latest version of Rosy is the modular Rosy_Mod. It is designed for small weapon stations and light vehicles of the kind used by special operations forces. Rosy_Mod is integrated directly into the vehicle without a surface-mounted launcher, thus making it undetectable. Source rheinmetall-defence.com

The Revolution MBT is only slightly heavier than its predecessor. It weights 60 t, comparing with 56.6 t of the original Leopard 2A4.

In 2010 Singapore upgraded its 96 ex-German Leopard 2A4 tanks with the AMAP composite armor, which is a part of the Revolution upgrade package. Upgraded tanks are known as the Leopard 2SG. (*Note Singapore only operates 66 the remaining 30 are used as spare parts)

Singapore Leopard 2SG and Leo 2A4

The Revolution MBT retains a fully-stabilized 120-mm / L44 smoothbore gun of the Leopard 2A4. The gun is loaded manually. It is compatible with all standard NATO 120-mm tank munitions, as well as the latest programmable HE rounds. These rounds enable to engage targets behind cover and within buildings. A total of 42 rounds are carried for the main gun. 15 rounds are stored in the turret bustle and are ready to use, while remaining rounds are stored in the hull.

It did complete trials on the British Challenger II, but there are no plans in the near future to equip it. It can fire the same rounds as the L44. Source tanknutdave.com

120mm HE DM 11 Tank Ammunition

Rheinmetall developed its 120mm x 570 DM11 cartridge on behalf of the German MoD. From the technical standpoint, it is characterised first and foremost by the programmability of the chambered round and by its airburst capability. The necessary system modifications (programmability) can be retrofitted into any modern MBT with a 120mm smoothbore gun. Modular in design, the DM11 consists of warhead with a programmable fuse as well as a ballistic cowl, tailfin assembly, drive band, combustible casing with propelling charge, and a newly designed case base containing the primer and an integrated data cable for programming.

The DM11 is designed for engaging lightly armoured targets such as vehicles, antitank positions (whether dug-in or in the open), field fortifications, double reinforced concrete walls as well as earth and timber bunkers .

Furthermore, thanks to its high precision and maximum effective range of up to five kilometres, it can be used for penetrating barriers and engaging targets taking cover behind walls, etc., as well as for breeching enemy defences and creating avenues of approach for friendly forces in built-up areas.

120mm KE DM63 / DM53 A1 Tank Ammunition

dm_63_grDM53 120mm KE Projectile (Rheinmetall)

The DM53 round was designed to maximize the performance of KE projectiles fired from 120mm smoothbore guns such as the L44 (15% improvement) or L55 (30% improvement in muzzle energy). The DM53 is in service with the German, Swiss and Netherlands Armies. The complete round weighs 21.4kg, the projectile (with sabot) weighs 8.35kg and propellant: 8.9kg. The projectile’s length is 745mm, and with chamner pressure of 5,450 generated during firing, the muzzle velocity is 1,750 m/sec (L55 barrel) and 1,670 m/sec. (L44 barrel). The DM53 has been optimized to lass than 0.2 mil accuracy.

DM 53-A1 is an advanced version of the DM 53. Currently being supplied in series to the armed forces of Germany, Austria and Turkey as the DM 63. DM53-A1 was selected by the armed forces of Finland and Denmark.

DM63 KE Cartridge (Rheinmetall)

The DM63 round is based on the DM53, with modified propulsion-based Temperature Independent Propulsion System (TIPS) utilizing the SCDB technology. The new type uses 8.45 kg of pure bulk powder to achieve nearly the same muzzle velocity of the DM53 (1,650 m./sec on L44 barrel). The propellant modifications aimed at improving the accuracy through a wide operational temperatures (-46 +63C) ensuring safe operation extreme climate zones, and minimizing the erosion of the barrel.

120mm PELE Tank Ammunition

120pele

PELE technology makes it possible to produce fully inert projectiles. The new technology modifies the projectile performance characteristics, significantly enhancing the accuracy of tank and artillery fire, while substantially reducing the risk of collateral damage. Non-explosive PELE ammunition consists of a high-density casing containing a core made of low-density, low-compressibility material. Upon impact with the target, the low-density material inside the shell is compressed to such an extent that the casing bursts, generating numerous fragments that are propelled in the direction of fire. This way, the round’s lethal impact is restricted to a defined space or limited area, reducing the likelihood of collateral damage. PELE and ALP make it possible to manufacture warheads containing little or no explosive. Moreover, existing ammunition can be inexpensively retrofitted with PELE and ALP technology. Both technologies can be integrated in full- and sub-caliber rounds, and fired from current and future weapon systems.

In August 2006 Rheinmetall Defense acquired the industrial property and trademark rights of PELE and ALP. According to Rheinmetall, the company plans to market them in conjunction with ammunition procurement and upgrade programs both at home and abroad. Concurrently, negotiations are underway with Diehl BGT Defence GmbH & Co. KG of Überlingen, Germany to acquire licenses in various special caliber segments. Source defense-update.com

Climate control

An entirely new air conditioning and ventilation concept ensures maximum crew comfort even in warmer climates. Air conditioning and thermal insulation in the fighting compartment, coupled with optimum ventilation and separate cooling of the driver’s compartment, result in a level of efficiency never attained before. Moreover, by ensuring that the ammunition on board remains fully functional, thermal insulation of the magazine contributes to operational safety. Thanks to intelligent control, the new climate control system automatically adapts to changing ambient conditions, assuring optimum use of energy. Simple cleaning and maintenance procedures are an added plus. source rheinmetall-defence.com

Auxiliary power unit

APU unit for illustration – Image: jenoptik.com

APUs have become increasingly important, especially in light of recent technical developments. Using an APU can optimize a vehicle’s energy balance. In many cases battery capacity is insufficient, especially when older types are used. If the battery power drops below a certain level the engine has to be started to recharge them. This results in excessive fuel consumption as well as producing unwelcome noise and heat. Fitting an APU can solve this problem. source rheinmetall-defence.com

The Revolution MBT also retains the MTU MB-837 Ka501 turbocharged diesel engine, developing 1 500 horsepower. Vehicle is fitted with auxiliary power unit, which powers all systems when the main engine is turned off. Cross-country performance is similar to that of its predecessor. (*Error it is MTU-873)
