The agreement forms part of a wider strategy to build closer, long-term partnerships with key suppliers, creating a simpler and more consistent way to bring specialist engineering expertise into critical defence programmes. The framework enables suppliers to support multiple projects more quickly, helping streamline procurement and strengthen collaboration.

The award of the framework builds on decades of infrastructure support to Babcock’s Devonport Royal Dockyard, His Majesty’s Naval Base Clyde, and the Rosyth Royal dockyard, and enables on-going and future support to critical UK defence and submarine programmes, as well as broader support for platforms and infrastructure across the nuclear, marine, land, and air domains.

“Our decades of naval nuclear infrastructure experience, the breadth and depth of our engineering and architectural skills, together with our unrivalled scientific reach back, makes Amentum a one-stop shop for Babcock’s engineering, nuclear and technical requirements,” said Loren Jones, senior vice president and head of Amentum’s Energy & Environment-International business. “We are looking forward to supporting the delivery of programmes vital to the UK’s safety and security in the years ahead, deploying our proven experience of modernizing the UK’s naval bases, dockyards and defence systems, including specialized technical validation for critical infrastructure such as docks, berths and shiplifts for the maintenance of Astute and Dreadnought-class submarines, and for the wider Royal Navy fleet.”

Amentum provides complex programme, project and engineering solutions, including: requirements management; architectural design and building services; multi-disciplinary design engineering (marine, civil / structural, electrical, control and instrumentation and mechanical); and specialist technical support, such as safety case authoring, Human Factors, 3D Building Information Modelling, geotechnical studies, seismic / blast assessment and Independent Technical Assessment. Amentum also supports critical defence programmes more widely, providing research and technology services, safety case, and security services for the Royal Navy’s nuclear propulsion systems.
