Amentum said it will create 3,000 new jobs in the U.K. over the next four years, citing rising demand in nuclear power and defense.
CEO John Heller, who met President Donald Trump and Prime Minister Sir Keir Starmer at Chequers earlier Friday, said:
“The U.S. State visit reflects the unique strength of the UK-U.S. partnership and our shared determination to drive economic growth and prosperity. The energy resilience and national security of both nations depend on continued leadership and advances in energy and technology – the focus of this visit. Commitments by both governments to back and invest in these industries help drive Amentum’s continued growth and investment in innovation, jobs and skills on both sides of the Atlantic.”
Amentum is a lead delivery partner for the Hinkley Point C and Sizewell C nuclear power stations and provides project support for small modular reactors and fusion research. The company said stronger coordination between the U.K. and U.S. nuclear sectors will be critical to meeting Trump’s executive order calling for a fourfold increase in nuclear generating capacity by 2050.
“We are stepping up collaboration between our people on both sides of the Atlantic to ensure that we seize opportunities which are tailor-made for our company,” said Mark Whitney, president of Amentum Energy & Environment. “Based on current demand projections, we expect to increase our UK headcount by 50% over the next four years. And we are also investing in digital engineering, AI, and automation to improve the delivery of critical infrastructure and government programmes in the UK and the U.S.”
In addition to its nuclear work, Amentum provides safety and technology services for the Royal Navy’s nuclear submarines, manages the U.K. training estate for the Defence Infrastructure Organization and supports the Atomic Weapons Establishment with program management and engineering services.
