LONDON : The British Army is preparing to enter a decisive new phase of artillery modernisation, with the first RCH 155 wheeled artillery demonstrator now expected to be delivered in 2028 under a joint programme with Germany, according to a parliamentary disclosure issued in January 2026. The move reflects a broader reassessment of British long-range fires capability shaped by the war in Ukraine, the donation of legacy systems to Kyiv, and the renewed centrality of land warfare on NATO’s eastern flank.
Defence Minister Luke Pollard confirmed that the United Kingdom will receive an Early Capability Demonstrator as part of a bilateral agreement with Berlin, marking the earliest point at which the British Army can begin formal trials of a wheeled self-propelled artillery concept under national service conditions. While the demonstrator does not constitute a production commitment, it feeds directly into the Army’s Mobile Fires Platform programme, intended to deliver a durable replacement for retired and transferred tube artillery later in the decade.
A Joint Investment With Strategic Weight
The RCH 155 demonstrator is funded through a £52 million agreement signed in December, committing both governments to a shared assessment and demonstration phase. Delivery is scheduled for the second quarter of 2028, with a joint evaluation period running through late 2029. Officials on both sides have indicated that testing and demonstration will proceed in parallel, an approach designed to compress timelines and enable earlier decisions on configuration, cost and production standards.
Beyond national capability development, the programme carries wider geopolitical significance. By aligning requirements and assessment schedules, London and Berlin are reinforcing defence-industrial ties at a moment when European allies are under pressure to regenerate heavy forces and sustain credible deterrence. A shared artillery solution enhances interoperability within NATO formations and contributes to a more coherent allied fires architecture, particularly as the alliance confronts the prospect of prolonged confrontation on its eastern frontier.
The programme is embedded within the Trinity House Agreement, the bilateral defence cooperation framework governing joint procurement, industrial collaboration and operational alignment between the United Kingdom and Germany. Officials have made clear that the objective is to converge on a common build as soon as a fully costed proposal becomes available, reducing divergence and avoiding the fragmentation that has historically undermined European land systems.
From PzH 2000 to Boxer
At the heart of the system, the RCH 155 combines the Artillery Gun Module derived from Germany’s Panzerhaubitze 2000 (PzH 2000) with the Boxer 8×8 armoured vehicle developed by ARTEC. The result is a highly automated, unmanned turret mounting a 155 mm L52 cannon compatible with NATO-standard ammunition.
With conventional projectiles, the system is assessed to achieve ranges beyond 40 kilometres, extending to approximately 54 kilometres when firing extended-range munitions. The turret provides full 360-degree traverse and operates across all elevations and charge combinations without stabilising outriggers, relying instead on inherent firing stability and a reinforced chassis.
Automation defines much of the RCH 155’s design philosophy. Integrated command, navigation and fire-control systems enable automated gun laying, projectile handling and modular charge loading. From a road-march position, the system can deliver its first round in under 20 seconds, sustain rates of fire of up to nine rounds per minute, and conduct Multiple Rounds Simultaneous Impact (MRSI) missions, with as many as five projectiles arriving on target within a two-second window.
German trials in 2021 also demonstrated firing-on-the-move capability, expanding mission profiles to include convoy protection, encampment defence, and rapid response fires against fleeting or time-sensitive targets.
Mobility, Protection and Crew Concept
Survivability and mobility are closely linked to the Boxer platform. The forward-mounted crew compartment houses a two-person crew comprising a driver-operator and commander, both remaining under armour throughout operations. Ballistic protection is provided by AMAP modular armour, reaching STANAG 4569 Level 4, with resistance against 14.5 mm armour-piercing rounds and an assessed ability to withstand 30 mm threats across the frontal arc.
Mine protection is enhanced by a multi-layered floor designed to absorb blasts equivalent to 10 kilograms of TNT beneath the hull or wheels. Power is supplied by an MTU V8 diesel engine producing more than 800 horsepower, enabling road speeds of up to 100 kilometres per hour and an operational range of around 700 kilometres. These characteristics support rapid redeployment across dispersed theatres, a key requirement for modern artillery operating under persistent surveillance and counter-battery threat.
Doctrine Shaped by Ukraine
The British Army’s interest in the RCH 155 is closely tied to lessons emerging from Ukraine, where artillery units operate under constant observation by drones, counter-battery radars and precision strike systems. Rapid emplacement and displacement, often described as “shoot and scoot”, have become essential for survival, placing a premium on automation, mobility and digital fire control.
Networked data links allow wheeled artillery units to operate in a more dispersed posture while remaining responsive to manoeuvre forces and higher-level fires coordination. These attributes align with the Army’s evolving doctrine for deep fires, as it seeks to integrate long-range artillery more closely with sensors, intelligence and joint effects.
Bridging the Capability Gap
The demonstrator phase will also allow the Army to examine how a wheeled artillery system integrates with existing brigade structures, logistics chains, and command architectures. Issues such as ammunition resupply under fire, maintenance demands, and compatibility with British communications and sensor suites remain central to the evaluation.
This process is informed by experience with the Swedish Archer system, acquired as an interim capability following the transfer of AS90 self-propelled guns to Ukraine. While Archer has highlighted the operational advantages of automation and reduced crew burden, it has also underscored the constraints associated with limited fleet size and bespoke sustainment arrangements.
Looking Beyond 2028
By the time the joint UK-German assessment concludes in the fourth quarter of 2029, London aims to be positioned to make a decision on a long-term production solution for its future artillery force. If successful, the RCH 155 programme would not only restore a critical British capability but also stand as a concrete example of coordinated European defence procurement in response to a more dangerous security environment.
As NATO adapts to the realities of high-intensity land warfare, the British Army’s pursuit of a modern, mobile and interoperable artillery system underscores how lessons from Ukraine are reshaping force design, alliance cooperation and the balance of deterrence across Europe.
