Executing the largest defence contract in UK history with Rolls-Royce Submarines

Some contracts shape industries. Others strengthen economies. This one secures a nation.

As Rolls-Royce Submarines (RRS) continued its decades-long mission to support and modernize the UK Royal Navy’s nuclear submarine fleet, they needed a partner who could cut through complexity, align national security priorities, and drive industrial innovation — all while navigating one of the most significant defence agreements in UK history. Our team stood at the helm to ensure smooth sailing.

A contract built for impact.

More than just an agreement, Unity consolidates eight contracts into a single, strategic framework which:

1. Secures £400 million in taxpayer savings
2. Ensures long-term investment in the UK’s defence supply chain
3. Supports over 5,000 highly skilled roles
4. Creates over 1,000 new jobs across Derby, Glasgow, and Cardiff
5. Strengthens workforce development with over 200 apprentices trained annually at the Rolls-Royce Nuclear Skills Academy

“Unity ensures the UK remains a leader in defence innovation, economic growth, and strategic security for generations,” Adrian said. “Working collaboratively with Rolls-Royce and MoD, we’ve created a model that ensures efficiency, long-term stability, and critical skills development.”

Powering the future of UK defence.

As geopolitical threats shift, the UK’s nuclear deterrent remains a cornerstone of national (and global) security. Unity cements the country’s role within the AUKUS alliance, alongside the United States and Australia, advancing the development of next-generation nuclear-powered submarines.

In Parliament, Maria Eagle, UK Minister for Defence Procurement and Industry, underscored the agreement’s impact. “[Unity] underpins the Government’s triple-lock guarantee to our continuous at-sea nuclear deterrent and our important AUKUS defence and security partnership,
