Rolls-Royce Submarines has entered into a memorandum of understanding (MOU) with global technology leader Siemens, marking a significant step in advancing digital optimisation across engineering and manufacturing processes. Signed at the Defence & Security Equipment International (DSEI) event in London this September, the agreement aims to accelerate the development of new Rolls-Royce technologies while reducing costs and mitigating risks within an increasingly complex operational environment.

Shared Expertise to Minimise Time to Production

The MOU encourages close collaboration between the two organisations, promoting the sharing of knowledge, expertise, and best practices. The primary goal is to reduce the time required to bring new technologies into production, ensuring that Rolls-Royce can deliver innovations faster, more efficiently, and with greater reliability.

Supporting the Royal Navy’s Submarine Fleet 

With a workforce of over 5,000 employees, Rolls-Royce Submarines designs, manufactures, and provides in-service support for the pressurised water reactors that power every submarine in the Royal Navy fleet. By leveraging digital tools and Siemens’ technology, the company aims to further strengthen its engineering and operational capabilities, ensuring optimal performance and readiness of the fleet.

Siemens Xcelerator Platform: Driving Digital Transformation 

Siemens contributes its proven software and hardware solutions through the Siemens Xcelerator open business innovation platform. This platform enables organisations to transform processes, accelerate innovation, enhance productivity, and improve overall efficiency. By integrating these tools, Rolls-Royce Submarines can better manage complex engineering tasks and streamline operations across the lifecycle of its products.
