A National Endeavour: Nuclear as part of the Defence engine for growth

Published 23 April 2026

Introduction

As the Strategic Defence Review made clear: the UK’s nuclear deterrent is the bedrock of our national security and the cornerstone of our commitment to NATO and global security.

The government’s support for defence nuclear is absolute, underpinned by its triple lock, guaranteeing (i) the building of four Dreadnought submarines, (ii) that we will maintain our nuclear deterrent, and (iii) the delivery of all future upgrades to ensure the safety and effectiveness of our submarines.

The UK’s Defence Nuclear Enterprise (DNE) is responsible for hundreds of projects of differing scope, scale and specialism. This includes two submarine build programmes – with a further one in design – the replacement warhead programme, major infrastructure upgrades including at two naval bases, and a new nuclear fuels programme.

Delivering this work is a National Endeavour: creating jobs, driving growth, and strengthening security. In every corner of the country the collective efforts of tens of thousands of people are helping our country to prosper and keeping us and our NATO Allies safe.

The Strategic Defence Review highlighted the need for sustained investment across the DNE. We are meeting that call: investing £15bn into the UK’s sovereign warhead programme during this Parliament; recapitalising critical elements of our infrastructure; modernising our naval bases and manufacturing processes; and investing £6bn over the Spending Review period to transform our industrial base and deliver continuous submarine production, allowing the UK to produce a submarine every 18 months.

The landmark AUKUS agreement is unlocking new opportunities for British industry as we develop the next generation of attack submarines and support Australia to build their own capabilities.

A strong Defence is a key foundation of a growing economy, and through the Defence Industrial Strategy we are embarking on a new era for our defence industry. DNE investments are transforming communities around our sites, creating opportunities across the country, stimulating development through our supply chain and establishing Britain as a global leader in innovation.

This booklet provides information on how defence nuclear is driving growth in your area, along with examples of the innovative and world-leading technology being developed and deployed through our partnerships with industry and academia.

The UK’s Defence Nuclear Enterprise: delivering security and growth.

The DNE is an engine for growth

Transforming communities

DNE investments boost regional and local economies. We are supporting regeneration and sustainability: unlocking opportunities in areas around our key sites, and funding initiatives that strengthen local infrastructure and services.

In Plymouth, a £4.4bn investment oven ten years in HMNB Devonport and Devonport Royal Dockyard and a new £50m Defence Growth Deal will support a range of programmes to transform the city’s future through defence-driven opportunity, innovation and growth. Building on existing government investment of £175m, ‘Team Plymouth’ will strengthen the city region through targeted initiatives in skills, housing, and transport to build long-term capability and prosperity.

Opened in 2024, The Bridge on Portland Walk provides a space where local organisations and third parties can promote the wide range of career opportunities in the area. As part of a major housebuilding expansion over 800 new homes are being built at Barrow Waterfront, and £23m is being invested to improve the road infrastructure connecting Barrow to other key industrial sites on the Cumbrian coast.

Recognising Barrow’s role as a strategic national asset, DNE spending is fuelling substantial growth and expansion. The economic certainty from the government’s commitment to the submarine building programme underpins the 10-year Plan for Barrow, backed by the £200m Barrow Transformation Fund. A £5m Social Impact Fund will support Barrow’s voluntary community and social enterprise sector, and a £5m Brilliant Future Fund investment in local schools is boosting aspiration and supporting the needs of Barrow’s young people.

Creating opportunities

The DNE supports over 47,000 jobs across the UK. This is expected to grow to 65,000 by 2030 as we transform our submarine production capacity and see increased demand in our programmes including AUKUS and Dreadnought. As well as nuclear expertise of scientists and engineers, the DNE depends on skilled trades such as welders, electricians, and mechanical fitters.

Thousands more construction jobs are being created to deliver infrastructure projects such as AWE’s new Future Materials Campus in Aldermaston and the redevelopment of HMNB Clyde, as well as at industrial sites in Plymouth, Barrow, Derby and Sheffield.

AUKUS will see both the UK and Australia benefit from the exchange of skills, people, and knowledge. The programme will further strengthen the UK’s submarine design, procurement and project management expertise. New educational and operational training programmes are being established to support AUKUS requirements, as we support Australia to build their capability to safely operate and maintain this next generation of attack submarine.

The Nuclear Skills Plan contains a range of initiatives to ensure we have the pipeline of future skills we need. In 2024/25, 778 graduates (up 27%) and 1,675 apprentices (up 20%) started with defence nuclear organisations, with 20 funded nuclear fission PhDs helping to develop a new generation of UK experts. We are working with industry and academia with the aim of creating 22,000 apprenticeships and 9,000 graduate roles in defence nuclear by 2034/35. Through compelling storytelling, real-life role models and targeted outreach, the Destination Nuclear Campaign is helping shift perceptions and spark interest in careers in the nuclear sector.

Regional Skills Hubs are now active in the South West, the Midlands, the North West and in Scotland, connecting local talent with national programmes and acting as anchors for training, outreach, and employer collaboration.

Our major industry partners – BAE Systems, Babcock International Group and Rolls-Royce Submarines – have established dedicated nuclear skills academies at their key sites in Barrow, Plymouth and Derby respectively. These provide current and future generations of our nuclear workforce with the skills and practical experience needed to sustain our largest and critical programmes. The new University of Cumbria Barrow campus – established with support from BAE Systems and the government’s Towns Fund – is supporting the town’s future economic, skills, cultural and social development.

Stimulating supply chain development

With a supply chain of over 6,000 UK-based companies, defence nuclear makes a pivotal contribution to the government’s mission to build a resilient, high growth UK defence industry. The government’s commitments send a clear demand signal to industry, and the long-term nature of DNE programmes incentivises and stimulates investment and development right through the supply chain.

The DNE spent over £9bn directly with its industry partners in FY24/25. This investment then cascades across the country through the supply chain. Large contractors and SMEs across the UK are seizing the opportunities presented by defence nuclear to modernise and expand their machinery, processes and workforce – kickstarting growth and creating jobs. Our Submarine Enterprise Supplier Development Programme is supporting several companies to improve performance, cost-effectiveness and upskill their workforce.

Submarines contain thousands of specialised components, many of which can only be sourced from suppliers with nuclear qualifications. The work of our industrial base is highly‑skilled, complex and often unique, and we continue to work to address entry barriers. Recent supply chain conferences, including one hosted by the Australian High Commission, have brought hundreds of organisations together, fostering understanding and deepening collaboration, and helping companies identify and secure new opportunities across our programmes.

With its trilateral supply chain AUKUS provides UK companies with significant new opportunities. Australia has made a commitment of £2.4bn over 10 years into our submarine industrial base to support their AUKUS requirements. The AUKUS programme is expected to deliver billions of pounds of exports for UK companies from enhanced demand into the supply chain from Australian orders.

Government investment in infrastructure, equipment and workforce capability is building a more resilient UK submarine manufacturing enterprise. More than £6bn will be spent over this Parliament with a range of suppliers and locations, including at BAE Systems in Barrow and Rolls-Royce in Derby, to deliver our commitment to continuous submarine production. £425m of additional funding (taking total Ministry of Defence investment to £1.3bn) is helping Sheffield Forgemasters to dramatically increase their efficiency, capacity and productivity. A new 13,000 tonne heavy forge and 30,000m² machine hall will feature 26 of the world’s most advanced, large heavy-duty machine tools, and secure over 700 jobs.

Driving innovation

The UK must maintain strategic advantage over our potential adversaries. The DNE’s multi-billion-pound investment in R&D ensures the UK remains at the forefront of emerging and advanced technology, driving innovation and increasing productivity across our industrial base.

This includes investing in seven ‘Catapult Centres’ across the UK to enable industry, scientists and engineers to work together on late-stage R&D. With a focus on emerging technology, this network of High Value Manufacturing Catapult Centres helps to commercialise the UK’s most advanced manufacturing ideas.

A new £110m Royal Navy Submarine Training Centre at HMNB Clyde will reach full operational capability in 2026. Alongside the Submarine Escape, Recovery and Survivability facility, UK submariners achieve true operational readiness through state-of-the-art training environments, deploying cutting-edge and highly immersive technology and simulators.

The Clyde Innovation Cell’s annual exhibition at HMNB Clyde enables industry and academia to showcase technologies aimed at increasing efficiencies in submarine maintenance.

AWE has established seven strategic partnerships with universities across the country, each providing world‑leading technical and research expertise in areas critical to the development and delivery of DNE programmes. They have committed to establishing five new Centres of Excellence to deliver strategic and collaborative R&D across scientific computing, future systems materials technology, quantum computing and sensing, actinides research and nuclear data. A partnership with Space Park Leicester has led to significant advancements in environmental testing and analysis.

AWE is also home of the Orion Laser Facility, one of the most powerful lasers in the world. Orion is a high energy density physics experimental facility that enables AWE scientists and physicists to improve their understanding of nuclear warhead science. The Orion laser can replicate conditions found at the centre of the sun and simulate supernovas in the lab.

Collaboration with our AUKUS partners in high-tech capabilities such as nuclear propulsion and advanced manufacturing is promoting UK academic excellence while driving groundbreaking achievements through knowledge-sharing. The second AUKUS Innovation Challenge was launched by the Defence and Security Accelerator in March 2025, with up to £6m of funding available for projects focused on undersea Command, Control and Communications.
