Rolls-Royce Submarines breaks ground on major Derby expansion
Rolls-Royce Submarines has officially broken ground and started foundational work on its new manufacturing facility, as part of plans to double the size of its entire Raynesway site in Derby.
This wider expansion activity will help meet the increased demand from the UK and Australian Royal Navies to boost production output for current and future submarine programmes. It will see over 100,000m² of new manufacturing and office facilities being built and create 1,170 skilled roles across a range of disciplines, including manufacturing and engineering.
The ceremonial event saw Lord Coaker, minister of state for defence; Abi Clayton, president, Rolls-Royce Submarines; and Commodore Alistair Moody, director for nuclear propulsion at the Submarine Delivery Group, dig the first ground together.
In June 2023, it was announced that Rolls-Royce planned to double the size of its Submarines site, where it designs and builds the nuclear reactors that power all Royal Navy submarines and helps maintain the UK’s continuous at sea nuclear deterrent. As part of the AUKUS partnership between Australia, the UK and the US, the company will also provide reactors for the future Australian SSN-AUKUS attack submarines.

While on site, Lord Coaker also met with Rolls-Royce nuclear welding apprentices who recently secured first, second, third and fourth place in the SkillWeld 26 East Midlands heats – the first time that all top-three places have been won by the same company.
SkillWeld is a national competition designed to showcase and benchmark the talents of trainee and apprentice welders. It highlights the exceptional skill required to succeed as a nuclear welder and follows on from welding apprentice Jack Billingham being selected to represent Great Britain at the WorldSkills event in Japan.
Abi Clayton, president, Rolls-Royce Submarines, said: “Breaking ground is a significant step forward in the critical growth of our business. This expansion will more than double the size of our manufacturing facility, strengthening our capability and demonstrating our ongoing commitment to the Defence Nuclear Enterprise.
“Together with our trusted delivery partners, our commitment is to deliver this programme safely, efficiently and to the highest standards. This work will unlock much-needed manufacturing capacity on site, allowing us to enhance our delivery drumbeat to support the boat build programmes.”
Lord Coaker, minister of state for defence, added: “The expansion of the Rolls-Royce site is a clear demonstration of the government’s commitment to the UK’s nuclear deterrent. Witnessing the manufacturing of the fifth SSSN-AUKUS reactor and the hundreds of apprentices in action was inspiring – seeing defence investment creating jobs, driving growth, and keeping the UK safe.”
