£708 Million Contract Accelerates UK Future Combat Air System as Supply Chain of 600 Companies Mobilises

Air July 27, 2026

A major contract extension with BAE Systems and Team Tempest partners will sustain more than 4,500 jobs across the UK and draw on a nationwide supply chain of around 600 companies as the UK’s Future Combat Air System programme moves into its next phase of development.

The government has announced a £708 million contract to accelerate development of advanced technologies for the UK’s Future Combat Air System, with the work to be led by BAE Systems alongside Team Tempest partners Leonardo UK, MBDA UK and Rolls-Royce. The investment, announced at Farnborough International Airshow by Defence Secretary Wes Streeting, extends the existing FCAS programme and builds on more than £5 billion invested by the UK government since 2018, with a further £8.6 billion committed to GCAP over the next four years through the recently published Defence Investment Plan.

The contract sustains more than 4,500 workers developing cutting-edge capabilities across artificial intelligence, advanced software, digital engineering, augmented reality, additive manufacturing and robotics. Approximately 90 per cent of those roles are based outside London and the south-east, reinforcing the programme’s role as a genuine engine for regional economic growth. Around 600 companies and academic institutions form the programme’s supply chain, making FCAS one of the most geographically distributed and industrially significant defence programmes currently running in the UK.

The technologies being developed under this phase span both military and dual-use applications. Digital engineering capabilities – described as first-in-the-UK – are a central focus, alongside AI integration and advanced manufacturing methods that have applicability well beyond combat air. The previous phase of the programme delivered measurable progress across digital engineering infrastructure, physical capability expansion and the maturation of technologies required for future combat air systems, providing the foundation on which this latest investment builds.

The contract’s relationship to the Global Combat Air Programme is direct and strategically significant. GCAP – the trilateral programme being developed by the UK, Japan and Italy to deliver a sixth-generation combat aircraft – requires a robust and technically advanced domestic industrial base to underpin the UK’s contribution. The FCAS programme provides that foundation, developing the sovereign technology, skills and infrastructure that position the UK as a leading partner in GCAP rather than a dependent one. BAE Systems Group Managing Director Simon Barnes described FCAS as representing the UK’s ambition to shape the future of combat air and secure a leading role in the technologies and capabilities that will define air power for decades to come.

For the wider defence technology ecosystem, the announcement signals continued and expanding demand across a set of capability areas – AI, digital engineering, advanced manufacturing and systems integration – that sit at the intersection of defence and the broader technology economy. The programme’s scale, its supply chain reach and its long-term investment horizon make it one of the most significant sources of sustained demand in the current UK defence pipeline.

For the UK defence supply chain

The FCAS programme’s supply chain of approximately 600 companies represents one of the largest and most technically demanding industrial ecosystems in UK defence. For businesses with capabilities in advanced engineering, digital technologies, AI, precision manufacturing and systems integration, the programme’s continued expansion – backed by £8.6 billion committed to GCAP over the next four years – signals a long and visible pipeline of opportunity across multiple tiers of the supply chain. The emphasis on regional distribution and the involvement of academic institutions also points to opportunities for businesses and research organisations across the UK that may not yet see themselves as part of the combat air supply chain.
