Defence Nuclear Enterprise 2025 Annual Update to Parliament

I am today placing in the Library of the House the Defence Nuclear Enterprise 2025 Annual Update to Parliament.

This Government has been clear that we are wholly committed to maintaining our nuclear deterrent. This has been reinforced through our triple lock, which guarantees the building of the four Dreadnought nuclear submarines in Barrow-in-Furness, that we will maintain our Continuous At-Sea Deterrent, and the delivery of all future upgrades to ensure the safety and effectiveness of our deterrent. Alongside this triple lock, we are committed to keeping Parliament informed on the work of our Defence Nuclear Enterprise (DNE) and providing regular updates on the progress of our key activities.

The work of the DNE is vast. Bringing together the Defence Nuclear Organisation, the Royal Navy, UK Strategic Command, the Submarine Delivery Agency and AWE Nuclear Security Technologies, the DNE is working on hundreds of projects and programmes across the breadth of the UK, including some of the largest, most complex and technologically advanced programmes the Government has ever undertaken. The DNE has a supply chain of over 3,000 UK-based businesses and a workforce demand of over 48,000 jobs across the UK, with this demand set to grow to 65,000 by 2030. The DNE’s programmes represent a substantial investment into industry and the UK’s economy. It spent £10.9 billion in financial year 2024-25, with final figures subject to audit, and has a projected spend of over £100 billion through UK suppliers over the next ten years.

Taken together this work constitutes a National Endeavour for the UK and is driving economic growth in every corner of the country. I am hugely grateful to other Government Departments for their continued support to us in delivering our deterrent.

In an era of rising global threats and uncertainty and conflict in Europe, it is as critical as ever that we work together to demonstrate our enduring resolve. I look forward to continued engagement with my Parliamentary colleagues over the next year as we update you on the progress on maintaining and renewing our nuclear deterrent.
