LONDON, Oct. 22 (Xinhua) -- Britain has resumed domestic production of large-calibre gun barrels for the first time in 20 years, with a new facility in central England supporting 100 skilled jobs, the Ministry of Defence said on Thursday.

The facility, operated by German defense manufacturer Rheinmetall in Telford, manufactures barrels and breeches for 120mm and 155mm weapon systems, including the RCH 155 artillery platform.

British Defense Secretary Wes Streeting officially opened the facility alongside senior military and company officials on Thursday. "Britain is back in the business of making the weapons that our Armed Forces need to defend the nation against our adversaries," he said in a statement.

According to the Ministry of Defence, Rheinmetall UK transformed the site from an empty facility into a fully operational production plant in just eight months after taking it over in autumn 2025.

The ministry said that the project forms part of a broader defence industrial partnership between Britain and Germany under the Trinity House Agreement signed in October 2024, aimed at strengthening bilateral defence cooperation and NATO's collective deterrence.

The British government has committed 298 billion pounds (about 400 billion U.S. dollars) to defense over four years under its Defence Investment Plan.
