Defence

We play a vital role in supporting the UK’s Defence Nuclear Enterprise

We deliver complex engineering and infrastructure solutions that maintain, upgrade and protect the country’s deterrent system.

From designing secure facilities to supporting the UK’s submarine fleet, our work ensures critical defence assets operate safely and reliably. As a long-term strategic partner to the Ministry of Defence and AWE, we provide integrated services across the entire defence nuclear lifecycle, from initial design through to final dismantling.

We lead the way in submarine decommissioning, including the world’s first nuclear submarine dismantling pilot at Rosyth and ongoing support at HMNB Devonport and HMNB Clyde. Our teams also help modernise naval dockyards and deliver engineering solutions for fissile material production facilities. With decades of experience and a strong reputation for safety and precision, we are trusted to deliver the infrastructure and expertise that underpin national security – today and into the future.
