BOXER tracked vehicle

Krauss-Maffei Wegmann (KMW) presented the BOXER tracked vehicle system for the first time at the EUROSATORY 2022 defence trade fair in Paris 13 to 17 June 2022. At Eurosatory, the tracked Boxer was equipped with a new RCT120 module weighing 14 tons. The turret itself, with a 120mm cannon, weighs eight to nine tons. KMW manufactures tanks and wheeled armored vehicles, but the medium-tracked vehicle was missing from its portfolio. Even Puma IFV (Infantry Fighting Vehicle) is a product of PSM (Project System Management), a joint venture between KMW and rival Rheinmetall. KMW, with the tracked Boxer, competes with the Rheinmetall Lynx. The tracked Boxer will attract the attention of users of wheeled Boxers.

Krauss-Maffei Wegmann (KMW) was incepted in 1999 when the military sector of Krauss-Maffei AG was acquired by Wegmann GmbH. Since then, it has grown to become the market leader for heavily armoured wheeled and tracked vehicles in Europe. The tried and tested BOXER system taken to the next level. The innovative tracked drive module has an increased level of protection and mobility that is otherwise only comparable to that of heavy tracked vehicles.

Although KMW calls its new machine the “Tracked Boxer,” the chassis section has no components in common with the wheeled Boxer. But the concept is the same. It's not a tracked Boxer in that they are not slapping tracks on the current wheeled drive module hull like GD did with the Stryker+TR. Both wheeled and crawler Boxers have a special storage tray on the body, into which special modules are inserted. Since the BOXER tracked is conceptually based on the modular system of the BOXER vehicle family, the drive module can be combined with all of the more than 20 different BOXER mission modules already introduced. The tracked variant is wider, so stowage room or additional armor can be added to the sides, with growth potential for active/reactive protection on mission modules and on the platform itself.

The tracked or wheeled Boxer can be used to create an armored personnel carrier, self-propelled howitzer 155 mm (RCH155), evacuation vehicle (MEDEVAC), command post, infantry fighting vehicle or tank destroyer with a 105mm cannon (Boxer MGS). With the new module with a 120 mm caliber tank cannon, Boxer has the potential to compete with Lynx. The chassis has a weight of around 28 tonnes, which leaves 17 tonnes for the payload, allowing to carry modules heavier than those designed for the Boxer, and obviously all those of the Boxer, mechanical and electric interfaces being exactly the same.

The chassis has six roadwheels, with the engine at the front left and the driver at its right. Propulsion is provided by an MTU 881 CR (common rail) turbodiesel engine giving up to 880 kW (1,180 hp) that considering the maximum GVW of 45 tonnes makes a power-to-weight ratio of over 26 hp/t. The engine is coupled to a Renk HSWL 256 fully digital controlled transmission with six forward and six backward gears, a derivative of the Puma tracked IF transmission. KMW experts underlined that the chassis is ready for accepting a hybrid propulsion system. The customer has the option to go for steel or rubber tracks.

In the military sector in particular, there are very specific requirements that military vehicles have to cope with. Therefore there is basically a specific vehicle for each task, such as transport vehicles, reconnaissance vehicles, rescue vehicles, but also combat vehicles with heavy armament. A modular vehicle system now offers the advantage over such a fleet of individual special vehicles that, depending on the requirements, different functional modules can optionally be used on the same carrier vehicle. For example, instead of a transport vehicle, a carrier vehicle can be equipped with a transport module, instead of a reconnaissance vehicle, the same carrier vehicle can be provided with a reconnaissance module, and instead of a recovery vehicle, the carrier vehicle can be equipped with a recovery module. The basic function of the vehicle can therefore be variably changed and adapted using a corresponding function module.

In terms of adaptability, it has been found to be advantageous if the modular vehicle system comprises several functional modules of different types, in particular a troop transport module, an artillery module, a howitzer module, an armored personnel carrier module, a battle tank module, a command post module, a medical module, a workshop module, a radar module, an anti-aircraft module, a supply module, a missile launch module, a mine clearance module, a pioneer module, a recovery module, a load transport module and / or a detection module. These different function modules can be arranged on the carrier vehicle as required.

With such modular vehicle systems, however, the adaptability is limited by the properties of the carrier vehicle. This is because, depending on the functional modules, the most important basic functions of the vehicle can be changed comparatively easily by replacing the functional module, but this does not apply to the vehicle properties, which are primarily determined by the carrier vehicle. For example, the off-road mobility of the vehicle cannot be changed by using a special functional module, and the selection or design of the functional modules is also limited in some cases, since they only have a limited load-bearing capacity and can only absorb limited forces.

Because of the recoil forces, this is a problem in particular in the case of functional modules that have large-caliber weapons. Proceeding from this, the invention has the task of specifying a modular military vehicle system that offers better adaptation to the requirements made. In a modular military vehicle system, this task is achieved in that at least two different carrier vehicle types, in particular a wheeled vehicle module with a wheeled chassis and / or a tracked vehicle module with a tracked chassis are provided, the functional module can be picked up by all carrier vehicle types.

The different carrier vehicle types mean that the properties of the carrier vehicle can also be adapted. The adaptability is therefore not limited to the selection of the function modules, but is expanded to include the selection of different carrier vehicle types. With a wheeled vehicle module, the corresponding function modules can be transported very easily on paved or unpaved roads, for example, but problems can arise on uneven terrain or on ice and snow due to the lack of traction of the wheels. In these situations, the tracked vehicle module offers an advantage, as it guarantees significantly more reliable progress on uneven terrain as well as on ice and snow.

Furthermore, tracked vehicle modules also offer advantages in the case of very heavy functional modules or those which, in particular, have large-caliber weapons. As a rule, tracked vehicle modules can absorb greater forces than wheeled vehicle modules.
