ATKINSREALIS AND MOTT MACDONALD APPOINTED TO ROLLS-ROYCE SUBMARINES PROGRAM

Atkinsrealis Group Inc. has been appointed to provide nuclear and infrastructure expertise to deliver critical nuclear-powered submarine facilities in the UK.

Rolls-Royce Submarines has jointly appointed AtkinsRealis and Mott MacDonald as its new fissile design partner as part of plans to double the size of its submarines site in Derby, England. The facility expansion is addressing significant growth in demand from the United Kingdom Royal Navy and the trilateral AUKUS submarine program, which will support Australia in acquiring its first conventionally armed, nuclear-powered submarine fleet. AtkinsRealis and Mott MacDonald, working together as the Propel joint venture, will design the new nuclear manufacturing facilities and work with the incoming fissile construction partner to deliver them.

Ian L. Edwards, president and chief executive officer of AtkinsRealis, said: "Demand for defence equipment and infrastructure is increasing, driven by the shift to strengthen national security from governments worldwide. AtkinsRealis is well positioned to support this rapid rise in major defence programs through our multidisciplinary expertise across defence, nuclear and complex infrastructure. This appointment reflects our ability to design and deliver highly specialized facilities that will help to increase the delivery rate of submarines for this critical program."

Rolls-Royce 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 security agreement between Australia, the United Kingdom and the United States.

Joe St. Julian, president, nuclear, AtkinsRealis said: "The design and build of nuclear-powered submarines involves highly complex platform requirements and safety standards as well as extensive knowledge of maritime infrastructure and submarine facilities. Alongside our nuclear fuel management knowledge, AtkinsRealis will bring significant experience to the program through our expertise in maritime and complex defence infrastructure as well as designing civil nuclear at scale.

"Our appointment builds on our long-standing relationships with Rolls-Royce and within the U.K. defence sector, and we look forward to bringing the best of our defence nuclear capabilities in support of this internationally significant program."

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 United Kingdom 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.
