UK Defence Manufacturing: Seizing the £270bn Spending Surge

The UK defence manufacturing sector is experiencing its most significant expansion since the Cold War. Manufacturers across the country are being urged to seize the opportunity. With the government committing to lift defence and national security spending to 5% of GDP by 2035, including a core 3.5% defence budget, the impact on British manufacturing is huge.

This is not just a policy announcement. It marks a fundamental shift in how defence is viewed within the British economy. Defence has moved from a necessary expenditure to an engine of industrial growth. For manufacturers willing to adapt, the rewards could be substantial.

The Scale of the Opportunity

The numbers tell a compelling story. Defence spending is set to reach 2.6% of GDP by 2027, backed by £270 billion of investment this Parliament. The Ministry of Defence awarded 2,674 contracts worth a combined £23 billion between July 2024 and June 2025. Of these, 1,244 contracts, valued at £17 billion, went to UK-based suppliers.

Record Order Backlogs Signal Long-term Demand

BAE Systems, Europe’s largest defence contractor, reported a record order backlog of £83.6 billion in February 2026. This is up from £77.8 billion the previous year. Chief Executive Charles Woodburn described the current environment as a “new era” of defence spending that would drive growth for years to come.

The sector already supports over 272,000 jobs across the UK. Government estimates suggest another 50,000 will be created by 2035. Foreign direct investment has reached £1.4 billion since 2024, whilst defence exports hit a 40-year high of £20 billion in 2025.

Recent Contracts Show Government Commitment

The £1 billion New Medium Helicopter contract awarded to Leonardo in February 2026 shows the government’s commitment to UK defence manufacturing. The deal will see 23 AW149 helicopters built at Leonardo’s Yeovil facility. It sustains 3,300 jobs directly and supports 12,000 more across the UK supply chain.

Global Export Potential

The agreement positions Yeovil as Leonardo’s global centre for military helicopter production and exports. International orders could generate over £15 billion in export revenue over the next decade. The contract also establishes the UK as a leader in autonomous systems, with continued investment in the Proteus uncrewed air system.

The £453M Radar Contract Secures 1,300 highly skilled jobs across Edinburgh, Lancashire, and Luton. These are not isolated examples but part of a systematic effort to rebuild Britain’s defence industrial base.

Two-Thirds of Manufacturers Forecast Growth

Despite ongoing challenges including high energy costs, supply chain issues, and skills shortages, British manufacturers remain upbeat. Research from Crowe, conducted with the Confederation of British Metalforming, found that 66% of manufacturing businesses expect to grow in the next 12 months.

Resilience Despite Headwinds

This optimism is notable given the headwinds the sector has faced. The Jaguar Land Rover cyberattack exposed supply chain weaknesses. Rising employment costs and geopolitical tensions have created uncertainty. Yet manufacturers recognise that defence spending offers one of the few reliable growth drivers available.

As Johnathan Dudley, Partner and Head of Manufacturing at Crowe, noted: “The government’s call for defence ‘reinvestment’ is a welcome sign of encouragement. Manufacturers now have a patriotic duty to play their part in revitalising growth.”

The SME Challenge and Opportunity

Despite roughly 12,000 SMEs already working in defence and national security, only around 4% of Ministry of Defence contracts are awarded directly to smaller businesses. The government has set clear targets to increase SME involvement to £7.5 billion annually by 2028.

New Support for Smaller Firms

To address barriers that have historically excluded smaller firms, the Ministry of Defence launched the Defence Office for Small Business Growth in January 2026. This service aims to simplify procurement processes and help SMEs navigate defence contracting.

Luke Pollard, Minister for Defence Readiness and Industry, was direct about the strategic importance: “In more difficult times, being able to bring more of our supply chain to Britain, or to friendly NATO partners, is absolutely vital to building our war-fighting readiness and deterrence.”

Babcock has also launched an SME charter to strengthen the defence supply chain. It focuses on proportionate contracting requirements and helping smaller firms test and develop technologies for defence programmes. Similarly, the £20M Fund Opens Defence Contracts to UK startups, creating new pathways into the sector.

Regional Manufacturing Benefits

One of the most compelling aspects of UK defence manufacturing investment is its regional distribution. Around 70% of defence industry jobs are located outside London and the South East. They are concentrated in manufacturing heartlands across the West Midlands, South West, and North of England.

Investment Across Britain

The Ministry of Defence spends nearly £7 billion annually with the defence industry in the South West alone, supporting more than 37,000 jobs. Scotland has recently benefited from a £50 million defence growth deal. This includes a £10 million skills package for two Defence Technical Excellence Colleges.

This regional dimension matters because defence sector roles tend to be highly skilled and well-paid compared to other regional jobs. Defence firms are also more likely to invest in apprenticeships and retraining programmes. This creates a virtuous cycle that builds the skilled workforce the sector needs.

Beyond Military Hardware

Manufacturers considering defence opportunities should understand that the sector’s needs extend far beyond sophisticated military equipment. The reality is much more diverse, and that breadth creates opportunities for businesses across multiple disciplines.

Diverse Contract Types

The government has committed to upgrading 40,000 military homes over the next decade. This creates work for construction firms, building materials suppliers, heating and ventilation specialists, and facilities management companies. Modern defence increasingly depends on digital systems, cybersecurity, data management, communications infrastructure, and supply chain solutions.

Food supply, textiles for uniforms, maintenance services, training facilities, and logistics all fall within the defence procurement footprint. Manufacturers with precision engineering capabilities developed for automotive or aerospace clients may find their skills directly transferable to defence applications.

Financing and Investment Requirements

Entering the defence supply chain often requires significant upfront investment. Businesses may need to achieve specific certifications, expand facilities, hire additional staff, or adapt operations to meet security requirements. For SMEs, these barriers can seem daunting.

Funding Options Available

Lloyds Banking Group has made £35 billion of funding available to firms operating or investing in the UK in 2026. Of this, £9.5 billion is specifically allocated for SMEs. Dave Atkinson, UK Head of Manufacturing at Lloyds, emphasised the bank’s commitment: “We’re here to support companies entering or expanding in the defence space.”

However, the Crowe research revealed a concerning trend: 82% of manufacturers are funding growth through internal reserves. This is a 30% increase from the previous year. This reliance on self-financing is unsustainable and suggests that external capital remains difficult to access despite stated availability.

The research also showed that 54% of manufacturers cite uncertain return on investment as the main barrier to innovation and R&D spending. For defence applications, where development timelines can be lengthy and procurement processes complex, this uncertainty is understandable but must be overcome.

Strategic Imperatives for Next-Generation Manufacturing

At the Make UK National Manufacturing Conference in March 2026, Business Secretary Jonathan Reynolds outlined the government’s vision for next-generation manufacturing. His message was clear: “Securing Britain’s transition to next generation manufacturing is not an option. It’s a strategic imperative.”

The Three Pillars

The speech emphasised three pillars: conception (how products are designed), production (how they are made), and utilisation (how they are sold globally). British manufacturers must invest in digital twin technology, advanced simulation, and AI-driven engineering. They must also modernise production facilities and develop export capabilities.

Rolls-Royce’s pioneering work in digital twin technology and BAE Systems’ integration of advanced modelling and AI into defence platforms demonstrate what’s possible. The challenge is extending these capabilities across the broader manufacturing base. Developments like the UK and EU Restart Defence procurement talks could further expand opportunities for British manufacturers.

Practical Steps for Manufacturers

For manufacturers considering defence opportunities, several practical steps warrant consideration.

Getting Started

First, assess existing capabilities through the lens of defence needs. Precision engineering, robust quality assurance, and reliable logistics are valued across defence applications. Many manufacturers already possess transferable skills.

Second, understand the certification and security requirements early. These vary by contract type but can take time to achieve. Starting the process before specific opportunities arise provides competitive advantage.

Third, engage with the ecosystem. The Defence Office for Small Business Growth, regional defence clusters, and industry bodies such as Make UK provide pathways into the sector. Networking with businesses already working in defence can provide invaluable insights.

Building Partnerships

Fourth, consider collaboration. Larger defence contractors need capable suppliers and are increasingly open to partnerships with SMEs that can deliver quality and reliability. Babcock’s SME charter specifically aims to facilitate such relationships.

Fifth, secure appropriate financing. Whether through banks, the National Wealth Fund, or UK Export Finance for export-focused activity, external capital may be necessary to scale operations appropriately.

The Window of Opportunity

The current moment represents a genuine inflection point. European defence spending is increasing substantially in response to geopolitical pressures. The UK government has positioned defence as a cornerstone of its industrial strategy.

Market Growth Projections

The Defence Investment Plan, expected this spring, will provide detailed guidance on procurement priorities. It will help businesses understand where they might fit. The UK defence market, valued at $26.76 billion in 2026, is forecast to reach $38.05 billion by 2031. This represents a compound annual growth rate of 7.29%.

Early movers typically gain advantages that become difficult for later entrants to replicate. The businesses that invest now in understanding defence requirements, achieving necessary certifications, and building relationships within the sector will be best positioned to capture their share of this historic investment.

Conclusion

The UK’s commitment to increased defence spending represents more than a security policy. It is an industrial strategy with huge implications for UK defence manufacturing. The scale of investment, the regional distribution of opportunities, and the breadth of goods and services required create openings for manufacturers across the country.

The challenge is execution. Manufacturers must move beyond viewing defence as a distant and inaccessible market. With the right preparation, investment, and support, businesses of all sizes can participate in what the government explicitly describes as making “defence an engine for growth.”

The two-thirds of manufacturers forecasting growth despite challenging conditions demonstrate the sector’s underlying resilience. Channelling that resilience towards defence opportunities could prove transformative. Not just for individual businesses, but for British manufacturing as a whole.

The window is open. The question is whether British manufacturers will walk through it.
