Britain and Germany have formalized a £52 million agreement to jointly acquire and evaluate the RCH 155 8×8 self-propelled howitzer, launching an Early Capability Demonstrator program intended to fast-track artillery modernization and deepen defense collaboration under the Trinity House framework.
Under the arrangement, the UK will operate one prototype while Germany will test two systems, allowing both nations to combine technical assessments, operational trials, and data analysis ahead of any long-term procurement decisions. The initiative reflects a growing emphasis on cooperative development to accelerate capability delivery within NATO.
The RCH 155 is emerging as a potential cornerstone of the British Army’s future artillery architecture, supporting plans to replace aging platforms through the Mobile Fires Platform initiative. Built around a 155mm L52 gun mounted on the Boxer wheeled armored vehicle, the system offers a blend of mobility, automation, and long-range firepower, with engagement ranges extending to 70 km with advanced ammunition.
Unlike traditional tracked howitzers, the RCH 155 is optimized for rapid, networked operations, featuring an unmanned turret, automated ammunition handling, and digital fire-control systems. The platform can execute a fire mission shortly after halting and displace quickly to avoid detection, enhancing survivability in high-threat environments. Its fire-on-the-move capability represents a significant evolution in NATO artillery operations.
The turret design is based on Krauss-Maffei Wegmann’s AGM, operated entirely from within the protected Boxer hull. A 30-round automated magazine supports MRSI firing, allowing multiple shells to strike a target simultaneously. By leveraging the Boxer platform—already central to the UK’s mechanized forces—the RCH 155 offers substantial advantages in logistics, interoperability, and strategic mobility.
