MBT Leopard 2 Revolution

The MBT Revolution is a modular upgrade package to the Leopard 2A4 main battle tanks. It was developed by Rheinmetall. This MBT was first revealed in 2010. It is also referred as Leopard 2A4 Evolution. The Leopard 2A4 was the most widespread version of the Leopard 2. It is still used by a number of countries in large numbers. So the market for upgrades remains substantial. 

MBT Leopard 2 Revolution
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. 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. 

MBT Leopard 2SG
The Revolution MBT is only slightly heavier than it's predecessor. It weights 60 t, comparing with 56.6 t of the original Leopard 2A4.

In 2010 Singapore upgraded it's 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.

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.

The Revolution MBT is also fitted with a remotely controlled weapon station, armed with a 12.7-mm machine gun. There is also a coaxial 7.62-mm machine gun. 

This main battle tank is fitted with new state-of-the-art fire control system. It has improved first round hit probability. The Revolution MBT also has improved reconnaissance and observation capabilities. The commander has new 360° periscope, which gives the vehicle a hunter/killer capability. The tank is also fitted with a battlefield management system.

Vehicle has a crew of four, including commander, gunner, loader and driver.

The Revolution MBT also retains the MTU MB-837 Ka501 turbocharged diesel engine, developing 1500 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 it's predecessor.

Since 2011 a broadly similar upgrade programme is offered by the Aselsan of Turkey. These are referred as the Leopard 2 Next Generation. It was locally developed as a private venture to meet a possible requirement of the Turkish Army.

 Rheinmetall’s mission-oriented, modular upgrade for main battle tanks

The altered mission spectrum of today’s armed forces has drastically changed the requirements imposed on modern main battle tanks. It is clear that they will continue to play an important role in current and future conflicts. But in the vast majority of cases, that role will have far less to do with winning tank battles than with securing positive outcomes in asymmetric scenarios. By presenting a massive show of force, MBTs deliver an uncompromising message to friends and foes alike, acting as a game-changer in conflict situations worldwide. New missions and new threats, coupled with availability of new technologies, are driving the need for modernization of fielded systems. What armies need now are efficient, cost-effective solutions.

Recent advances in survivability, lethality, command and control capabilities as well as reconnaissance and sighting systems mean that there are now new ways of significantly improving overall MBT performance. Moreover, new solutions for optimizing crew performance in all environmental conditions, especially in hot climatic zones, are available too.

Given the projected remaining service life of today’s main battle tanks – the Leopard 2, for example, is likely to be in military inventories for least another thirty years – a made-to-order extension of capabilities is clearly a worthwhile investment.

As Europe’s foremost supplier of systems and equipment for ground forces, Rheinmetall offers not only a full range of tactical vehicles, but also a unique array of C4I, fire control and sensor technologies, lethal systems and force protection solutions. Comprehensive service and maintenance support also form an integral part of the Group’s expertise base, as do its wide spectrum of simulation and training systems, which includes state-of-the-art combat training centres.

These capabilities – deriving from a single source – are particularly pertinent in upgrade programmes, where the optimum interplay of new and existing components is crucial. Moreover, Rheinmetall has an extensive international network of partner companies. The Leopard for example, embodies the combined expertise of Krauss-Maffei Wegmann and Rheinmetall, two of the most trusted names in the German defence industry. Today, some 5,000 of these tanks are in service with many satisfied user nations around the globe. Rheinmetall also serves as prime contractor for all Leopard-based armoured engineering and armoured recovery vehicles as well as bridge-laying tanks based on the Leopard 1.

Labelled the MBT Revolution, Rheinmetall now offers a comprehensive upgrade approach for main battle tanks – a modular concept capable of meeting the current operational needs of user nations as well as assuring adequate future growth potential.

Revolutionary aspects of the Rheinmetall concept include, in particular, a protection package as well as an extensive array of reconnaissance and target acquisition systems with a comparatively modest increase in weight, keeping it within the MLC 70 weight class. Moreover, an optimized stowage concept keeps alteration of the vehicle’s contours to a minimum.

  • Weight class: MLC 70
 Protection concept

By combining numerous individual components and measures, Rheinmetall has 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.
 Commander’s brake

Using tanks in contemporary conflict zones imposes certain requirements, some of them entirely new. Today, military operations often take place in built-up, heavily populated places, where great care has to be taken to avoid harming innocent civilians, causing friendly casualties or inflicting other forms of collateral damage; if not, the ensuing political fallout can easily wipe out weeks of operational gains.

In cooperation with RENK, Rheinmetall has developed a commander’s brake for the Leopard 2, which enables the commander to bring the tank to a partial or total halt. Observing, reconnoitring, identifying and engaging targets have long been subject to commander/gunner redundancy; now, for the first time, the critical safety feature of stopping the vehicle is available as an optional backup as well.

The commander’s brake can be integrated into any Leopard 2-type tank or combat support vehicle quickly and cheaply.

 Digital turret concept

http://www.military-today.com/tanks/revolution_l1.jpgToday’s tanks are equipped with analogue turret systems which fail to provide the commander with a night vision capability, and which offer only limited possibilities for observing the effectiveness of fire, for example, and no means of digitally transmitting or processing video signals.

Rheinmetall has developed two ways of improving performance here. The first keeps the core analogue systems in place while adding advanced components (laser rangefinder, commander’s periscope, gunner’s thermal imaging system, etc.), which are integrated via interfaces. This economical solution makes it possible to bring important components up to date, and enables at least partial digitization of the system. However, this solution fails to make the best use of the limited space in the turret, and makes obsolescence unavoidable.

Rheinmetall’s globally unique digital turret concept, on the other hand, involves a complete overhaul of the core system, and is in many respects the optimum solution. This system requires considerably less space, and integrates all the components – from the vision system and fire control unit to the weapon engagement system to the C4I technology – into a single, highly efficient digital network, combining outstanding ergonomics, reliability and ease of use even in high-stress situations. The digital system reduces reaction times significantly, and increases the probability of a first-round hit. For the first time anywhere, an automated operating and weapon engagement concept gives the Rheinmetall system a hunter/killer capability. In connection with an intelligent C4I system, moreover, it features augmented reality as well as enabling training to take place directly in the vehicle in simulation mode.

 Reconnaissance systems

The Seoss digital fire control unit, which stands for "stabilized electro-optical sensor system", provides an enhanced vision capability. Two-axis stabilized, it is equipped with a Saphir thermal imaging device, a daylight camera and an eye-safe laser rangefinder. The data required for evaluating the situation – including the target, system status, range and ammunition type – appear on a display in the fighting compartment. Seoss enables day and night engagement of targets even when the tank is on the move, including in periods of poor visibility. The user can choose between a 360° panoramic view of the battlefield or a coaxial, weapon-aligned perspective. Seoss also features an integrated fire control computer for six different types of ammunition.

In addition, an integrated situational awareness system (SAS) permits panoramic surveillance of the immediate vicinity of the tank, automatically detecting and tracking potential targets, helping to relieve pressure on the crew. The SAS consists of two to four modules, each covering 3 x 60°, plus high-definition colour cameras and high-performance night vision components. An interface to the fire control unit enables instant transmission of detected target data, enabling immediate engagement of emerging threats, primarily with the RCWS.

 Remote control weapon stations

A remote control weapon station (RCWS) forms an essential part of a tank’s self-defence capability. One possible solution is the QIMEK, developed by Rheinmetall Canada, and mounted on the MBT Revolution tank. Modular design and a high degree of flexibility are the twin hallmarks of this fully stabilized remote control weapon station. Equipped with a universal cradle, the system can be fitted with a variety of different weapons, including a 40mm automatic grenade launcher. Moreover, virtually any optical system can be built into the QIMEK. Other RCWS models, e.g. from Kongsberg, can be easily integrated as well.

 Lethal systems

Rheinmetall is one of the world’s leading suppliers of large-calibre weapons and ammunition. The company’s globally acclaimed smoothbore L44 and L55 tank guns combine tremendous firepower with a high first round hit probability, even when the tank is on the move. Particularly in the field of weapons and ammunition, recent technological breakthroughs have let Rheinmetall make a vital contribution to the unsurpassed combat effectiveness of the Leopard MBT.

Rheinmetall’s latest ammunition product is the DM11, a 120mm HE tank round. Owing to its time-delay fuse, it is especially suitable for supporting infantry units tasked with taking lightly fortified positions as well as for engaging light and medium-weight armoured vehicles. After loading, an electronic module programs the time-delay fuse to detonate at a specific point in the projectile’s flight path: the round can be timed to explode for maximum effect either above, in front or inside of a target (e.g. after penetrating a wall). The DM 11 is thus a perfect match for the altered operational requirements of modern main battle tanks.

Based on the kinetic energy principle, the DM 53 (LKE II) is specifically designed to penetrate the latest multilayer tank armour, including reactive armour modules. The penetrator consists of a special tungsten alloy. The DM 53 can be fired from Rheinmetall L 44 and L55 tank guns.

Rheinmetall has developed the world’s first temperature-independent high-performance tank ammunition, the DM 63 and DM 53A1 (the latter is an upgraded version of the DM 53). What sets this round apart is its temperature-independent propulsion system (TIPS), which maintains its internal ballistic characteristics at a constant level through a broad temperature span. This new generation of ammunition is considerably more accurate and causes substantially less barrel erosion. The DM 63 can be used in climatic zones C2 to A1, and fired from any 120mm smoothbore tank gun.

The company’s newly developed 120mm PELE is an inert round. It contains no explosive and is therefore extremely safe to handle. When it hits its target, the low-density material inside the projectile becomes so compressed that it causes the warhead to burst, resulting in a large number of fragments, which travel exclusively in the round’s trajectory. This is especially advantageous in the case of semi-hard targets. PELE can be retrofitted into multipurpose ammunition or armour piercing rounds.

 C4I and network-enabled warfare capabilities

Featuring uniform system architecture, Rheinmetall’s Iniochos command and information system is available for every echelon from brigade headquarters all the way down the individual soldier on the ground. A growing number of countries, including Greece, Spain, Sweden and Hungary have already opted for C4I solutions from Rheinmetall.

Iniochos is a family of tactical command and control systems whose functionalities can be adapted to specific operational spheres, e.g. a tactical operations centre, tactical vehicle or dismounted infantry. One of its most prominent features is systematic application of NATO interoperability standards, a critical advantage during international operations. This standardized system enables soldiers from participating nations to generate and share a common, role-oriented operating picture.

The Iniochos family consists of a command post system for brigade and battalion level operations (Iniochos C), a tactical vehicle C4I system (Iniochos V), and an application optimized for dismounted troops, Iniochos S.

Designed to support modern tactical operations, Iniochos incorporates the full range of current interoperability standards used in combined and joint operations. User- and role-specific configurability, scalability and a concept enabling joint use mean that this system is equally effective at every level from brigade to individual soldier. The flexible communications concept enables all participants to remain in direct contact via the combat radio net.

 Climate control

An entirely new air conditioning and ventilation concept ensures maximum crew comfort even in hot 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.

 Auxiliary power unit

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.

 Service portfolio

Both at home and abroad, Rheinmetall’s longstanding experience in the defence technology sector makes it a competent and reliable partner, and service is no exception. The company’s service portfolio encompasses logistical analysis and support, efficient project management as well as innovative holistic concepts such as embedded logistics and telemaintenance for optimizing logistics during deployed operations, etc.

Rheinmetall’s Contractor Logistics Support (CLS) programme merits special mention. CLS is an integrated package of services that guarantees the availability and readiness of an entire fleet of vehicles for . The CLS programme encompasses weapon systems as well as vehicles, and is by no means restricted to routine peacetime operations.

The first service contract of this kind was signed in 1991 with the US Army, primarily in support of operations in the Gulf. Today, along with the US military, CLI clients include the armed forces of the UK, the Netherlands, Norway and the United Arab Emirates. In Germany, the Rheinmetall subsidiary Heeresinstandsetzungslogistik GmbH is responsible for keeping much of the German Army’s fleet of vehicles up and running.

To sum up. Balancing force protection and force projection, the main battle tank clearly has an important part to play in modern warfare and conflict management. No other land system combines firepower, survivability and mobility in quite the same way: its mere presence on the battlefield has the power to reassure friendly troops and break enemy morale. By creating greater operational flexibility, the many options of the MBT Revolution make it an economical solution that enables greater use of potentially decisive weapons systems already in military inventories.
