UK Orders 72 RCH 155 Howitzers in £1bn Trinity House Deal

Technical Summary

On 13 May 2026 the UK MoD announced a nearly £1 billion contract for 72 Remote Controlled Howitzer (RCH) 155 systems, awarded by the Organisation for Joint Armament Cooperation (OCCAR) on behalf of the British Army to ARTEC GmbH, the KNDS–Rheinmetall joint venture. The package includes initial training and in-service support. First deliveries are scheduled for 2028, with a minimum deployable capability planned within the decade.

The RCH 155 mounts a 155mm/L52 ordnance — identical in calibre and chamber to the PzH 2000 turret family — on a wheeled BOXER drive module. UK MoD figures cite a maximum range of 70 km (consistent with extended-range projectiles such as the Nammo HE-ER and Rheinmetall’s assisted natures) and a maximum rate of fire of eight rounds per minute. Automation of the turret reduces crew to two soldiers and enables shoot-and-scoot from the cab without dismounting.

Industrial and Supply Chain Analysis

Weapon system production — barrel, breech, recoil system and trunnions — will be performed at Rheinmetall’s new large-calibre facility in Telford, supplied with specialist gun-barrel steel from Sheffield Forgemasters. The BOXER chassis, engine and drive train will be manufactured by KNDS UK in Stockport. The MoD asserts 500 UK jobs across the prime sites and supply chain: 100 at Telford, 100 at Stockport, ~300 in the wider industrial base.

The contract follows a £52m Early Capability Demonstrator contract (December 2025) and a £53m Long Lead Item procurement contract earlier in 2026 that pre-funded long-lead forgings and machine tooling at Telford. From a procurement-engineering standpoint, this is the standard NATO de-risking pattern for a foreign-design adoption: incremental commitment ahead of the production buy.

Personnel and Safety Considerations

For ammunition technical officers and ammunition technicians, the RCH 155 adoption signals continued UK reliance on the NATO 155mm/L52 ecosystem and DM121/DM131-family bagged charges or modular charge system (MCS) increments. UK stockpile planning must accommodate extended-range natures (HE-BB/HE-RAP) at increased Net Explosive Quantity (NEQ) per round relative to legacy AS90 L15A2 HE. Hazard Division (HD) 1.1 (Compatibility Group D) remains the dominant classification for the HE filled natures; charge increments are typically HD 1.1 C. Storage and transport licensing under JSP 482’s successor (DSA 03.OME Part 2) should be reviewed against expected uplift in held stocks.

The RCH 155 replaces the AS90 batteries gifted to Ukraine in 2023; the Archer system remains the interim capability. The two-soldier crew concept compresses training pipelines but raises competence-assurance questions for the Royal School of Artillery: load-and-clear procedures, misfire drills (cook-off envelope on autoloader-fed natures), and storage-to-feeder transfers all require revised technical instructions.

Data Gaps

DATA GAP: Specific projectile families and charge systems to be procured alongside the platform have not been disclosed. NEQ figures for the chosen extended-range natures, the autoloader magazine capacity (typically 30 rounds for RCH 155), modular charge system selection (M231/M232A1 vs. UNI-MCS vs. bi-modular charge), expected stockpile depth at initial operating capability, and the precise variant of fuze (multi-option fuze, course-corrected, programmable) all remain open. The Long Lead Item contract scope has not been publicly itemised. Production capacity at Telford for steady-state output beyond the UK order is also not stated.
