Rheinmetall Unveils HX3-based Wheeled Self-propelled Howitzer

Since its foundation in 1889, Rheinmetall has been a world-leading centre of expertise for heavy artillery. The company’s new wheeled self-propelled howitzer is highly advanced, being specifically designed to meet international specifications for future-proofed indirect fire systems. The Rheinmetall wheeled self-propelled howitzer is mounted on a high-mobility HX 10×10 chassis made by Rheinmetall MAN Military Vehicles. Key criteria governing the system’s design include combining the operational reach of Rheinmetall’s high-mobility, operationally proven, HX military trucks with state-of-the-art howitzer technology, while simultaneously substantially extending the range of cannon artillery to gain range superiority over any enemy capability.

It is equipped with a highly protected cab and a fully automatic, remote-controlled artillery turret, which, though unmanned, can be entered by the crew. This means that it takes only two soldiers to operate the system from the safety of the armoured cab. The turret can rotate and fire through 360 degrees, drawing on a turret magazine containing projectiles and propelling charges for forty rounds. The tried, tested and inservice Rheinmetall L52 gun has been selected as the system’s main armament, with the L60 gun, now in development, offering future growth potential. The L60 can project low-cost standard projectiles (boattail; base bleed; V-LAP) more than 80 kilometres. Precision guided munitions such as the Vulcano will allow to engage high-value targets at even greater ranges.

Compared to other wheeled platforms, which are already hitting their weight and payload limits, using the HX 10×10 offers the advantage of unused growth potential of circa five tonnes of additional load capacity. Given an assumed service life of 30-40 years, this additional payload could be used to incorporate a multitude of additional mission systems as well as for carrying extra ammunition. Moreover, because the howitzer was designed from the start for remote-control and semi or full automatic operation, it can function without a crew. In keeping with the “human in the loop” principle, however, the fire order is never an autonomous decision.

When it comes to procurement and utilization, the howitzer offers an excellent price-performance ratio compared to traditional tracked self-propelled howitzers as well as other wheeled tactical vehicle-based systems, while at the same time substantially enhancing a core capability intrinsic to all howitzers: achieving favourable outcomes through range superiority. Thanks to the high-mobility HX 10×10 truck chassis, the artillery system can flexibly redeploy over large distances without additional logistic support, and with no need for routine maintenance or repairs upon arrival. Made by Rheinmetall MAN Military Vehicles, the HX family is among the most widely used range
of military trucks anywhere. Over 15,000 vehicles are now in service worldwide. A military-offthe-shelf family of vehicles, HX trucks are systematically designed for maximum durability, mobility, ease of use and modularity, effectively placing them in a class of their own.
