ATKINSREALIS SECURES MULTI-YEAR NUCLEAR PARTNERSHIP WITH ROLLS-ROYCE SUBMARINES

Atkinsrealis Group Inc. has been appointed to deliver nuclear propulsion and engineering capabilities to Rolls-Royce Submarines Ltd., supporting the United Kingdom's growing submarines program.

Under this framework agreement, Atkinsrealis will work alongside Frazer-Nash and Assystem to provide Rolls-Royce Submarines with the collective engineering expertise, nuclear capabilities and other professional services required to meet growing demand from the U.K. Ministry of Defence (MoD) and allied nations. The framework has a total value of up to 400 million British pounds over five years, with the option to extend for a further two years.

The Capability Assured Strategic Partnership (CASP) brings together nuclear capability to support the Royal Navy's submarines program and the U.K.'s wider Defence Nuclear Enterprise. The U.K. government has reaffirmed its commitment to nuclear as a cornerstone of its national security strategy, investing significantly to maintain and expand its world-class submarine program and enable the trilateral AUKUS (Australia, the United Kingdom and the United States) security agreement, which will support Australia in acquiring its first conventionally armed, nuclear-powered submarine fleet.

"Global defence investment is accelerating as nations seek to reinforce security and resilience," said Ian L. Edwards, president and chief executive officer of Atkinsrealis. "Atkinsrealis is uniquely positioned to support this growth through our multidisciplinary expertise in nuclear programs and complex infrastructure. This partnership with Rolls-Royce Submarines reflects our ability to deliver highly specialized capabilities that are critical to the safe and effective operation of future submarine fleets and wider defence programs."

"Nuclear propulsion systems for submarines require exceptional precision, safety and technical depth," said Joe St. Julian, president, nuclear, Atkinsrealis. "Our position in this new strategic partnership builds on 27 years working with Rolls-Royce Submarines on their defence programs and our end-to-end experience in nuclear life-cycle management. Together with our industry partners, we will help ensure the U.K.'s submarine enterprise remains robust, agile and ready to meet evolving defence needs."

Under the new partnership, Atkinsrealis will provide specialist support in nuclear propulsion systems, safety assurance, systems engineering and program delivery -- critical for the design, integration and life-cycle management of submarine reactor plants -- alongside consulting, environmental services, asset management, cyber resilience, digital solutions, and reactor design and substantiation.

The appointment follows Atkinsrealis and Mott MacDonald being announced as Rolls-Royce Submarines' joint fissile design partner in January, 2025, as part of plans to double the size of its submarines site in Derby, England. Combined, these appointments demonstrate Atkinsrealis's continuing and growing role in supporting the U.K.'s Defence Nuclear Enterprise and its commitment to delivering safe, reliable propulsion capability for future submarine fleets.

Rolls-Royce Submarines is currently supporting the existing Astute and Dreadnought boat build programs through the delivery of reactor plant and associated components. In March, 2023, it was confirmed that Rolls-Royce Submarines would provide all the nuclear reactor plants that will support the next generation of nuclear-powered submarines as part of the trilateral AUKUS agreement between Australia, the United Kingdom and the United States.

Notes

Atkinsrealis is providing design and engineering services to the new gigawatt-scale nuclear build program at Hinkley Point C and Sizewell C as well as working on operations, maintenance, decommissioning and nuclear waste management at nuclear sites across the United Kingdom.

Through its global defence market, Atkinsrealis supports critical defence programs to strengthen national security, from infrastructure design and complex program delivery to strengthening cyber resilience in the face of evolving threats. In the United Kingdom, Atkinsrealis has supported the U.K. Ministry of Defence (MoD) in major programs across the land, maritime, air and joint environments and is one of three firms jointly appointed as engineering delivery partners to the MoD's Defence Equipment & Support (DE&S) function.
