Rheinmetall UK Gun Hall opening ceremony.
Rheinmetall UK Gun Hall Telford: Britain has taken a significant step towards rebuilding its domestic defence manufacturing capabilities with the official opening of Rheinmetall’s new UK Gun Hall in Telford, marking the return of independent large-calibre weapons production to the country after a gap of around 20 years.
The facility, opened at a ceremony attended by Defence Secretary Wes Streeting and Rheinmetall AG chief executive Armin Papperger, will manufacture 120mm and 155mm weapon systems. These include components for the Challenger 3 Main Battle Tank programme and future artillery platforms, strengthening Britain’s ability to produce critical military equipment on home soil.
The development represents more than a new factory. It reflects a wider effort to strengthen the UK’s defence industrial base, reduce reliance on overseas manufacturing and ensure that the armed forces can access essential equipment as military demands grow across Europe and within NATO.
Rheinmetall’s investment also underlines the growing industrial relationship between Britain and Germany, supported by the Trinity House Agreement, which aims to deepen cooperation between the two countries.
What is the UK Gun Hall, and why does it matter?
Located in Telford, Shropshire, the UK Gun Hall is a specialised manufacturing facility designed to produce large-calibre weapon components, including gun barrels, breeches and breech blocks.
These components are essential to the operation of tank guns and artillery systems. Gun barrels guide projectiles as they are fired, while breeches and breech blocks form part of the mechanism that closes the rear of the barrel and helps contain the pressure generated during firing.
Manufacturing such components requires specialist engineering skills, precision equipment and rigorous quality control. Re-establishing this capability in Britain therefore provides more than additional factory space: it restores industrial expertise that is important to the country’s long-term defence requirements.
The facility has 11,500 square metres of production space and, at peak capacity, is expected to manufacture up to 245 barrels annually across the two calibres, alongside more than 50 breeches a year.
The production of 120mm systems is particularly relevant to Britain’s Challenger 3 tank programme, while 155mm systems support the country’s wider artillery requirements and future land warfare capabilities.
The factory is also intended to serve growing demand from the UK, NATO allies and international customers, potentially giving Britain a stronger role in the wider European defence manufacturing network.
From an empty building to production in eight months
One of the most notable aspects of the project is the speed at which the facility became operational.
Rheinmetall transformed an empty site into a functioning manufacturing operation in just eight months. During that period, the company installed and commissioned advanced machinery, transferred specialist technical knowledge from Germany and prepared its British workforce to manufacture complex weapon components.
Production milestones were achieved in quick succession. Manufacturing of breeches and breech blocks began in May 2026, followed by gun barrel production in June.
The successful manufacture of the first UK-produced breeches, breech blocks and barrels demonstrated that the facility could produce these components domestically.
The pace of development is significant because defence manufacturing projects often require substantial investment in equipment, workforce training and quality assurance before production can begin. Bringing these elements together within a short period demonstrates how an established international defence company can help restore industrial capacity when investment and technical expertise are available.
However, the factory’s opening is the beginning of a longer process. Building towards full production capacity, developing the workforce and establishing reliable supply chains will be essential to delivering its intended benefits over time.
More than 100 skilled jobs expected in Telford
The UK Gun Hall is also expected to provide a boost to the local economy.
Rheinmetall currently employs around 685 people in Telford, including 35 at the new facility. As production develops, the company expects the Gun Hall to support more than 100 highly skilled people.
The distinction between current staffing and projected employment is important: the workforce is expected to grow as manufacturing activity expands, rather than all the anticipated positions being in place at the time of opening.
The jobs will require expertise in precision engineering, advanced manufacturing, production processes and quality assurance. These are specialised skills that can support wider industrial development and create opportunities for workers seeking careers in engineering and defence manufacturing.
Rheinmetall has already recruited specialist workers from the Telford region, drawing on the area’s existing engineering and manufacturing expertise.
The company has also invested in training British employees at its production facility in Unterlüß, Germany. Workers gained experience in specialist manufacturing techniques before returning to apply that knowledge in Telford.
This transfer of skills is central to the project’s long-term value. Domestic manufacturing capability depends not only on machinery and buildings, but also on people who can operate equipment, maintain quality standards and develop production methods.
Rheinmetall’s Telford facility marks major step towards British defence manufacturing independence.
Strengthening British supply chains and the steel industry
The new facility could also create opportunities for British suppliers, particularly as production volumes increase.
Rheinmetall intends to work with UK small and medium-sized enterprises to develop resilient domestic supply chains. These businesses could benefit from demand for specialist components, engineering services and other manufacturing support, although the scale of individual contracts and their economic impact will depend on how the programme develops.
One important ambition is to introduce British steel from Sheffield Forgemasters into production.
Using domestically produced steel would help connect the Gun Hall with Britain’s wider industrial base, potentially supporting steelmaking expertise and reducing reliance on overseas sources for some critical materials.
The move would also reinforce the strategic importance of maintaining specialist manufacturing capabilities within the UK. Defence equipment can depend on complex international supply chains, and disruption to materials or component supplies can affect production schedules.
Developing more domestic capacity does not eliminate the need for international suppliers. Instead, it gives Britain additional options and may improve its ability to sustain manufacturing during periods of heightened demand or disruption.
A wider investment in Britain’s defence industry
The Gun Hall forms part of Rheinmetall’s investment of more than £200 million across its UK operations over the past five years.
The company’s activities also include work on the Boxer Mechanised Infantry Vehicle and the Challenger 3 Main Battle Tank programme, alongside future land capability projects.
These programmes serve different purposes, but together they demonstrate the breadth of Rheinmetall’s involvement in British defence manufacturing. The new factory adds another important capability by focusing on the production of large-calibre weapon systems and their components.
For the UK government, this fits into a broader ambition to make defence spending an engine for economic growth. Investment in military equipment can support jobs, industrial innovation and skills development, as well as the immediate objective of equipping the armed forces.
Speaking at the opening, Streeting described the facility as an example of rapid reindustrialisation, highlighting the return of large-calibre weapon production to British soil and the prospect of around 100 skilled jobs.
Papperger said the opening marked an important milestone for both Rheinmetall and the UK, adding that the company intended to expand its British industrial presence over the long term.
Rebecca Richards, managing director of Rheinmetall UK, also emphasised the role of British workers, skills and suppliers in turning the investment into an operational manufacturing capability.

The UK-Germany partnership and NATO security
The UK Gun Hall is also a practical example of industrial cooperation under the Trinity House Agreement between Britain and Germany.
The partnership combines Rheinmetall‘s established manufacturing expertise in Germany with production capability in the UK. This approach allows Britain to draw on existing technical knowledge while developing its own workforce and industrial infrastructure.
For NATO, stronger manufacturing capacity among member states can help improve the ability to equip armed forces and respond to changing security requirements. Russia’s war against Ukraine has underlined the importance of ammunition supplies, industrial readiness and the ability to sustain military operations over extended periods.
The Gun Hall’s planned output of tank and artillery weapon components contributes to this wider question of readiness. Its ability to support allied demand could also strengthen Britain’s position within Europe’s defence industrial network.
Nevertheless, a new facility alone cannot guarantee military readiness. Its contribution will depend on sustained production, access to materials, workforce development and the needs of the armed forces. The stated annual production figures represent peak capacity, not necessarily the output that will be achieved immediately.

A new chapter for British defence manufacturing
The opening of the UK Gun Hall marks an important milestone in Britain’s efforts to rebuild domestic defence production. It brings specialised manufacturing back to the UK, creates the foundations for skilled employment in Telford and offers opportunities to strengthen domestic supply chains.
Its significance lies in the combination of industrial capability, technical expertise and international cooperation. By transferring knowledge from Germany while developing production in Britain, Rheinmetall is helping establish a manufacturing base that could support current military programmes and future requirements.
The longer-term test will be whether the facility can expand production sustainably, deliver the expected employment benefits and integrate British suppliers into its operations.
If those ambitions are realised, the Gun Hall could become an important part of Britain’s defence industrial infrastructure, supporting the armed forces while contributing to the country’s wider manufacturing economy.
