UK orders 37 artillery weapon systems for RCH 155
The British Army has taken a significant step toward modernising its artillery forces, placing an order for 37 artillery weapon systems in support of its next‑generation Remote Controlled Howitzer (RCH 155) programme. The £53 million contract, awarded by the Organisation for Joint Armament Co‑operation (OCCAR) on behalf of the British Army, represents a long‑lead production agreement that will supply key components of the RCH 155’s artillery modules and support the early phases of the Mobile Fires Platform capability.
Officials describe the procurement as part of a broader effort to replace the Army’s legacy self‑propelled guns and restore artillery lethality aligned with modern operational requirements. The RCH 155, mounted on the Boxer armoured vehicle chassis, is envisioned as a highly mobile 155 mm howitzer capable of firing on the move, striking targets at extended ranges and improving survivability in high‑intensity conflict environments.
Closing the Capability Gap
The British Army’s artillery fleet has been challenged in recent years by the retirement or transfer of older systems. In particular, its fleet of AS‑90 self‑propelled guns was donated to allied forces, notably to support Ukraine’s defence against Russian aggression. This has created a gap in the Army’s long‑range cannon artillery capability that the RCH 155 is intended to fill.
To bridge this gap, the Army initially procured 14 Archer artillery systems from Sweden as an interim solution. While useful, these systems do not fully match the strategic depth and advanced features expected of the future Mobile Fires Platform. The RCH 155’s advanced automation, mobility, and firepower are designed to address that shortfall.
What the New Order Entails
The recent order for 37 weapon systems does not equate to 37 complete howitzer vehicles; rather, it focuses on the production of the artillery gun modules and related subsystems that will eventually be integrated into full vehicles. These include the 155 mm barrel, recoil mechanisms, automated loading systems, breeches and other critical artillery elements. The contract also supports significant investment in the UK’s defence industrial base, particularly in gun barrel manufacturing capacity. Around £30 million of the contract’s value is allocated to expanding facilities such as Rheinmetall’s “Gun Hall” in Telford, which is expected to create skilled jobs and bolster sovereign production capability.
By securing these long‑lead items now, the Ministry of Defence (MoD) aims to mitigate future production delays and ensure that the RCH 155 programme progresses smoothly. Long‑lead contracts are a common procurement practice in defence when key components must be manufactured well in advance of final assembly and delivery.
Technical Edge and Operational Promise
The RCH 155 system itself represents a leap forward in artillery technology compared with legacy guns. Developed by ARTEC GmbH—a joint venture between German and European defence firms—and integrated into the Boxer wheeled chassis, the RCH 155 combines automation, mobility and firepower. Advanced features include fully automated loading, remote operation of the gun module, and the ability to execute rapid “shoot‑and‑scoot” manoeuvres that reduce vulnerability to counter‑battery fire. The system is expected to fire up to eight rounds per minute and hit targets at ranges up to around 70 km depending on ammunition type.
Mounted on a wheeled vehicle capable of traversing road and off‑road terrain at speeds up to 100 km/h, this mobility is a crucial factor in modern artillery concepts, offering rapid repositioning and enhanced tactical flexibility.
Industrial and Strategic Dimensions
The RCH 155 procurement is not solely about military capability; it also reflects strategic defence industrial considerations. The UK’s investment in domestic production lines and technological infrastructure aims to enhance sovereign manufacturing capability and reduce reliance on external suppliers. The expansion of facilities like the Telford gun barrel plant is expected to sustain skilled employment and anchor artillery production within the UK industrial base.
This is seen as part of a broader effort to strengthen the UK’s defence supply chain, creating resilience against geopolitical disruptions and aligning production capacity with long‑term military needs. The collaboration with Germany under OCCAR also underscores continued bilateral cooperation on major defence equipment, as both nations look to standardise systems and share testing and evaluation data.
Uncertainties and Next Steps
Despite the recent contract award, the overall scale and timeline of the RCH 155 programme remain subject to further decisions. The MoD has previously stated that definitive delivery dates and fleet sizes are still under assessment, with the programme expected to achieve initial operating capability later in the decade once full production decisions are taken.
In the interim, the Army will continue trials and evaluation of prototype systems to inform future procurement phases. Assessments carried out jointly with German partners will help shape final configurations and operational requirements. The long‑lead contract for 37 weapon systems symbolises confidence in the programme’s direction, even if the complete buy plan has yet to be confirmed.
Broader Context
The push to renew artillery capabilities is driven by evolving battlefield realities and lessons learned from recent conflicts, including the importance of long‑range fires and rapid manoeuvre artillery on modern battlefields. The RCH 155 is part of an emerging generation of self‑propelled artillery systems that prioritise automation, mobility, and survivability.
As the British Army moves toward finalising production contracts and preparing for future delivery, the 37 weapon systems order stands as a key milestone in a long‑term effort to equip ground forces with agile and potent fire support.
