The UK Gun Hall in Telford, Shropshire, will produce barrels and breaches for 120mm and 155mm weapon systems, including for the RCH 155 howitzer and future artillery platforms. The facility has already created 100 jobs, with Rheinmetall indicating it plans to expand its workforce as production increases.
Staff at the plant received training at a Rheinmetall facility in Germany, specialising in precision manufacturing, quality assurance and specialist weapon production.
Defence Secretary Wes Streeting said the site marked a return of large calibre weapon production to UK soil for the first time in 20 years. "From an empty site to full production in eight months, this is rapid reindustrialisation in action," he said. "One hundred skilled jobs in world class manufacturing and the return of large calibre weapon production to UK soil for the first time in 20 years - this is what defence as an engine for growth looks like."
Rheinmetall CEO Armin Papperger said the gun hall was an "important milestone" that would strengthen the country's industrial base "for decades to come". The company has only one other similar production line, in Germany. "At the moment, we have a lot of orders and we need the capacity," Papperger told BBC Radio Shropshire. "Telford has very well-educated people, highly-motivated people."
Rheinmetall already contributes to the UK's Boxer combat vehicle programme and is involved in upgrading Challenger tanks. Papperger said the firm currently employs 1,300 people in the UK and aims to grow that number further. Streeting described Telford as "synonymous with engineering and manufacturing" and called the opening "a vote of confidence in our country."
