The UK Aerospace and Defence Market: A Guide for Overseas Suppliers

Overview

The UK has the world's second-largest aerospace industry after the United States, and is one of Europe's two largest defence spenders. Aerospace sector turnover was £30.5 billion in 2024 with over £20 billion exported, and the sector directly employed 104,000 people (ADS Facts 2025). The sector's export orientation means overseas suppliers compete for UK work on the same footing as UK competitors, and most of what they help produce is destined for international customers. The UK's Ministry of Defence (MOD) budget is rising to 2.5% of GDP by April 2027 under the Strategic Defence Review 2025 (SDR 2025), giving sustained programme funding that is politically locked in. UK space sector income stood at £18.6 billion for 2022/23 (Size and Health of the UK Space Industry 2024), a growing domestic market independent of defence.

The UK's civil aerospace industry is concentrated at a handful of sites. Airbus wing final assembly at Broughton is the only Airbus wing assembly site outside Germany, covering the A320 family today with A330 and A350 work expanding as build transfers from Airbus Belfast (the former Spirit AeroSystems Belfast operation, transferred to Airbus in 2025). Airbus wing design sits at Filton in Bristol, the centre of Airbus wing engineering. Rolls-Royce Civil Aerospace at Derby is one of only three companies in the world, with GE Aerospace and Pratt & Whitney, capable of designing and producing large civil engines end-to-end. GKN Aerospace at Filton and Western Approach in Bristol is the tier-1 structures specialist for wing and aerostructures content (Airbus in the UK).

In defence, the UK is known for four things: combat aircraft (BAE Systems at Warton and Samlesbury in Lancashire); aero engines (Rolls-Royce's defence division, plus submarine propulsion via Rolls-Royce Raynesway); warships (BAE Systems on the Clyde at Govan and Scotstoun, Babcock at Rosyth, and the Type 26 frigate and Type 31 frigate programmes); and submarines (BAE Systems at Barrow-in-Furness, Cumbria, building the Astute and Dreadnought classes, with Rolls-Royce as propulsion supplier). Aero engines cover both civil (the Rolls-Royce Trent family) and defence (EJ200, submarine reactors, the Global Combat Air Programme demonstrator), which is why Rolls-Royce appears on both sides of the story.

The UK aerospace industry is the country's largest manufacturing export earner, and defence is among the most ringfenced areas of the public budget. Both are taken seriously by government.

The UK supply chain is mature and consolidated. Entry tier depends on what you can bring. The easiest route in is to offer something the existing UK supply chain does not already have in abundance. Suppliers pitching standard components or generic materials that the UK base already produces at scale will find the market well served. Suppliers with a genuine specialism, or with capacity in areas where the UK supply chain is stretched, are actively welcomed. Specific areas where the UK base is stretched include defence-grade castings and forgings (particularly in nickel and titanium superalloys), complex aerostructure composites, certain precision electronics categories, and specialised energetic materials. These are where second-source interest from overseas primes and Tier-1s is consistently high.

Leading sub-sectors

Combat Air and GCAP

The UK is one of Europe's two major combat aircraft manufacturers, and the only country outside France with end-to-end design, manufacture and flight-test capability on a single industrial base. Programmes are concentrated at BAE Systems' Warton and Samlesbury sites in Lancashire, with supply-chain reach across the country.

Edgewing, the three-way joint venture between BAE Systems, Leonardo (Italy) and Japan Aircraft Industrial Enhancement Co (JAIEC) formed on 20 June 2025 to deliver GCAP (the Global Combat Air Programme), received its first international contract from GCAP International Government Organisation (GIGO) in April 2026: a £686 million award consolidating design and engineering activities previously run under separate national contracts (Leonardo; Breaking Defense). The three partners each hold a third of Edgewing. In-service target remains 2035.

Alongside GCAP sits the continuing Typhoon workload. Warton runs design and flight test, Samlesbury runs manufacturing, and the two sites together handle final assembly, modification and upgrade for UK, German, Italian, Spanish and export Typhoons, with Radar 2 and ECRS Mk2 extending sustainment through the 2030s. Samlesbury also produces rear fuselage and tail assemblies for every F-35 built, a permanent industrial position for the platform's life. BAE Systems posted £26.3 billion revenue in 2024 under CEO Dr Charles Woodburn (Nordic Defence Review). Leonardo UK employs over 8,000 across Edinburgh (radar, missile seekers) and Luton (electronic warfare, BriteCloud) (Leonardo UK). MBDA UK at Stevenage and Bolton sits on a £6.5 billion MOD complex-weapons framework from early 2024 (UK Defence Journal). Rolls-Royce leads the GCAP engine demonstrator with Avio Aero and IHI.

Combat air is one of the harder sub-sectors to enter directly. Common ways in for overseas suppliers run through specialist materials, coatings, bearings and precision machining into the Samlesbury and Warton networks via UK-based tier-1s; avionics and sub-assemblies into Leonardo where bilateral agreements enable classified work; and test equipment, tooling and specialist manufacturing gear. Export-control friction runs in both directions, and most overseas entrants accept a UK partner from the outset. The growth driver is the decade-long GCAP ramp to 2035 service entry, reinforced by SDR 2025.

Engines and Propulsion

Rolls-Royce is the UK's major aero engine manufacturer and one of only three companies in the world, with GE Aerospace and Pratt & Whitney, capable of designing and producing large civil engines end-to-end. Its Derby campus is the UK's civil engine centre. Bristol, via Aero Engine Controls, provides controls and accessories. Defence Aerospace and Rolls-Royce Submarines at Derby and Raynesway handle military engines and naval nuclear propulsion.

Group underlying revenue passed £20 billion in 2025, operating profit £3.5 billion, group margin 17.3%; Civil Aerospace alone reported a 20.5% margin (Rolls-Royce 2025 results). Chief executive Tufan Erginbilgic, in post since January 2023, has taken the company from post-pandemic crisis to its strongest balance sheet in recent memory.

On the civil side, the Trent XWB is sole powerplant on the A350 and booked 226 orders in 2024 on the -97 variant. The Trent 7000 is sole engine on the A330neo with 212 orders, a record. The Trent 1000 powers the 787. The Pearl family powers Falcon 10X, Gulfstream G700/G800 and BBJ. The UltraFan demonstrator, the first new Rolls-Royce architecture in 54 years, first tested at Derby on 100% sustainable aviation fuel in May 2023 and later reached full power with a 10% efficiency gain over Trent XWB (Rolls-Royce). In February 2026 Erginbilgic confirmed partners are being sought for a £3 billion UltraFan 30 narrowbody programme (Leeham News).

On defence, Rolls-Royce provides EJ200 for Typhoon via Eurojet, the F-35B LiftSystem and the GCAP demonstrator. Rolls-Royce Submarines at Raynesway employs over 4,000 and sustains the pressurised water reactors for every Royal Navy submarine; in 2025 the MOD placed the eight-year £9 billion "Unity" contract for reactor design, manufacture and support (Navy Lookout). Rolls-Royce SMR was selected as preferred bidder by Great British Energy - Nuclear in 2025.

Derby is the most concentrated aero-engine cluster in Europe outside Munich. Test Bed 80, the largest indoor aero-engine testing facility in the world, is the key site for civil development work; Raynesway is the key site for submarine-reactor build. Realistic overseas entry points are precision machining of blades, casings and discs; single-crystal turbine-blade casting; coatings; forgings; composites and CMCs; test instrumentation and MRO tooling. Rolls-Royce runs a structured supplier qualification process, typically 12-18 months. Growth drivers combine Trent aftermarket volume (Large Engine flying hours up 8% in 2025), the UltraFan 30 pathway, SMR industrialisation and AUKUS submarine-reactor pace.

Munitions and Energetics

Munitions and energetics is the most visible defence capacity story in the UK between 2026 and 2030. The UK's Strategic Defence Review in June 2025 committed £1.5 billion to rebuild munitions and energetics capacity, answering Ukraine-driven demand and depleted European stockpiles. The review confirmed at least six new factories during the current parliament, backing around 1,800 skilled jobs, with at least thirteen potential sites identified including Grangemouth, Teesside and Milford Haven (gov.uk munitions announcement; gov.uk factories of the future). The SDR frames a policy shift from campaign-driven procurement to continuous "always-on" production.

This is a generational moment for defence. We must move faster, spend smarter, and work with allies and industry to deliver the capabilities our Armed Forces need.

BAE Systems has invested over £150 million in UK munitions facilities since 2022. A new explosive filling facility at Glascoed, Monmouthshire, is built for a sixteen-fold increase in 155mm artillery shell production, though start-up has slipped more than six months on the summer 2025 schedule (The Engineer). An additional 155mm machining line is being added at Washington, Tyne and Wear. Royal Ordnance (RO Defence), BAE Systems' UK munitions subsidiary, employs around 1,260 across Glascoed, Radway Green, Washington, Birtley and related sites. Chemring Group reported £510.4 million of revenue in 2024, Countermeasures and Energetics up 16.8% to £322.7 million (Chemring). Thales UK Belfast produces NLAW under a £280 million restock contract running through 2024-2026, and handles Carl-Gustaf final assembly for Saab (Defense News). MBDA Bolton produces Storm Shadow, ASRAAM, Brimstone and UK Meteor workshare under the £6.5 billion Defence Equipment & Support (DE&S, the MOD's procurement arm) framework.

On this trajectory UK munitions capacity is set to rise to a level not seen since the Cold War. By 2028 to 2030 the expected pattern is BAE's Welsh and Tyne and Wear sites at the Glascoed uplift, Chemring and Thales at continuous production, and the new factories delivering insensitive munitions, propellants and large-calibre shell filling. The bottleneck is precursor materials: the UK energetics chain depends on imports of TNT, RDX and nitrocellulose at volumes Europe in aggregate cannot produce at scale. For overseas suppliers of precursor chemistry and capacity-expansion equipment, that import dependency is the genuine opportunity.

Practical entry routes tend to be propellants and explosive components, small-arms ammunition parts, 155mm shell body forgings and machining, pyrotechnics, fuzes, energetic materials R&D, test-range instrumentation, manufacturing automation and filling-line equipment. Growth drivers combine Ukraine-driven stockpile replenishment, NATO ammunition interoperability, GCAP weapons integration and the "always-on" policy shift.

Helicopters and Rotorcraft

The UK has just one helicopter manufacturing site: Leonardo's Yeovil plant in Somerset. Leonardo UK employs around 7,000 directly and supports around 10,000 supply chain jobs, making it the largest inward investor in the UK defence sector.

In March 2026 the MOD confirmed Leonardo's AW149 as the winner of the £1 billion New Medium Helicopter (NMH) programme, a 23-aircraft order to be built at Yeovil, securing 3,300 direct jobs at the site and 12,000 across the UK supply chain (MOD announcement; Leonardo, March 2026). MOD flagged an export pipeline of up to £15 billion over a decade. Until the decision, the long-term viability of Yeovil had been in serious doubt as Merlin and Wildcat orders wound down (FlightGlobal).

AW149 replaces the retired Puma HC2. Yeovil also sustains AW101 Merlin and AW159 Wildcat (new-build Wildcat ended in 2006), and supplies airframe sections and sub-assemblies into Leonardo's wider commercial output, where the AW139 passed 1,300 deliveries in 2024. Beyond Leonardo, UK civil rotorcraft operators are a second demand source: Bristow, CHC, Babcock Mission Critical Services, HM Coastguard and the air-ambulance charities run sizeable fleets across search and rescue, offshore wind, policing and HEMS.

Practical entry routes tend to be airframe structures, avionics line-replaceable units, cabin interiors, seating, transmission components and rotor-blade materials. Yeovil also buys tooling, jigs and test equipment. Civil operators are a separate market with lower security overhead and shorter cycle times. The growth driver is NMH production from 2026 through 2032, plus any AW149 export wins that widen Yeovil's workshare.

Space and Satellites

UK space is smaller than combat air or engines but internationally significant in specific niches, small-satellite manufacture in particular. The UK made more than 40% of the small satellites currently in orbit.

Sector income of £18.6 billion in 2022/23 was spread across 1,907 organisations and 55,550 direct FTEs (Size and Health of the UK Space Industry 2024); income was down 8.9% year on year in real terms, though respondents remained net-optimistic on the three-year outlook. The UK Space Agency (UKSA) has a £2.8 billion budget committed to 2030 (UKSA), and the 2025 Civil Space Strategy narrowed industrial focus to satcoms, space domain awareness, PNT, in-orbit servicing, data applications and space transportation.

The main national programme is Skynet 6A, built by Airbus Defence and Space at Stevenage, Portsmouth and Hawthorn, with a Falcon 9 launch planned for 2027. It sits within the wider £6 billion Skynet 6 programme covering the satellite, Babcock/Team Aurora service delivery and Skynet Enduring Capability (Airbus, May 2025). The merged Eutelsat-OneWeb constellation, with a UK Government special share, remains a strategic national capability. Post-Brexit the UK is no longer a full Galileo partner, but Stevenage and SSTL Guildford remain major ESA contributors via the Mars Sample Return orbiter and the Rosalind Franklin rover.

Dominant players are Airbus Defence and Space UK; Surrey Satellite Technology at Guildford (an Airbus subsidiary); the Harwell Space Cluster in Oxfordshire, home to 92-plus organisations including ESA ECSAT, the Satellite Applications Catapult and the UK National Space Propulsion Test Facility; and BAE Space, which acquired In-Space Missions in 2024. Reaction Engines went into administration in October 2024 and Skyrora entered insolvency in February 2026 (European Spaceflight). Practical entry routes tend to be sub-systems into SSTL and Airbus Stevenage and Portsmouth, payload components, RF and microwave, specialist materials and ground-segment hardware.

By 2030 the UK's ambition is to host Europe's only sovereign end-to-end small-satellite industry: manufacture in Glasgow and Harwell, vertical launch at SaxaVord Spaceport in Shetland (Scotland), the UK's licensed vertical-launch site, first orbital attempt targeted for 2026, and downstream services in Cornwall. Scottish vertical launch targets polar orbits the rest of Europe cannot easily serve. The 2021 target of 10% of the global space market has been scaled back, launch has slipped at both sites through 2024 and 2025, and the regulatory path for commercial vertical launch is still being worked through. Growth drivers are SDR 2025's Skynet Enduring Capability commitment, AUKUS Pillar 2 space domain awareness, and UKSA investment in the 2025 strategy's niches.

Unmanned Systems

Unmanned systems are a growing UK capability across both military and commercial applications. The RAF is bringing the GA-ASI Protector RG Mk1 (SkyGuardian) into service at RAF Waddington with IX(B) Squadron, the UK's flagship MALE UAV programme. BAE Systems is developing uncrewed combat air systems alongside GCAP, with autonomous platforms designed to operate in formation with manned fighters.

Below the primes sits a cluster of mid-size UK unmanned specialists building on MOD-funded programmes. Callen-Lenz in Salisbury is a tactical UAS specialist procured by UK defence and active as an exporter. Malloy Aeronautics in Maidenhead develops heavy-lift logistics drones under MOD funding. UAVTek, Blue Bear Systems Research and Overwatch Aerospace add further depth in tactical unmanned systems.

Overseas suppliers of autonomy software, sensor payloads, propulsion systems and airframe materials typically find more open engagement at this end of the supply chain than in the prime-dominated combat air sector. The security overhead is lower, the procurement cycles are shorter, and the companies are actively looking for partners.

Opportunities

UK aerospace primes face record order backlogs that their existing supply chains cannot fully absorb. Rolls-Royce's civil Trent order book exceeds USD 50 billion, and BAE's Typhoon, F-35 and Dreadnought commitments are pulling qualified capacity up to the ceiling. Commodity content into a well-consolidated supply chain should expect friction; openings cluster at the edges, in innovative processes, hard-to-find specialisms and capacity where the UK base is stretched.

Overseas-supplier entries into the UK fall into recognisable categories: precision-machined components (engine discs, casings, blades, flap tracks, landing-gear parts); composite structures and materials; electro-mechanical sub-systems (actuators, valves, pumps, environmental control); electronics (connectors, backplanes, displays, RF and microwave); cabin content; propulsion and munitions energetics; speciality materials (titanium and superalloy stock, coatings, bearings); and test, tooling and automation equipment. Build-to-print is the norm on legacy platforms; design-to-build is more common on new programmes such as GCAP, UltraFan, NMH and Skynet 6. UK primes are actively seeking second-source suppliers in casting, forging and machining after European capacity tightened from 2022.

Example offsets

An offset or industrial participation commitment is a condition attached to a defence equipment sale. When a foreign country buys UK defence equipment, the UK government or the UK prime supplier is typically expected to place business back in the buying country, establishing local production, transferring technology, or sourcing from that country's industry.

For an overseas supplier, the relevance runs both ways. If your home country has bought UK equipment, there may be reciprocal industrial participation opportunities: UK primes are obliged or expected to place business with companies in your country as part of that deal. The inverse also applies. When the UK buys foreign equipment, the seller is expected to place business in the UK, and overseas companies that establish UK industrial presence can capture that spend.

The UK does not run a formal offset regime of the kind Poland, Turkey or India use. Industrial participation is negotiated deal-by-deal on major platform acquisitions under the Defence and Security Industrial Strategy 2021 (DSIS) and the SDR 2025 framing (gov.uk DSIS). Social value weighting of 10% under Procurement Policy Note 06/20 is now routine in MOD scoring, which rewards UK jobs, UK SME participation and UK technology transfer.

Our Insights

British defence and aerospace procurement runs on understatement, and overseas suppliers repeatedly misread the signals. "We'll file that" or "that's interesting, we'll come back to you" almost always means no. "Thank you for your time" at the end of a meeting with no named next step carries the same weight. Silence beyond four weeks after a submission is negative, not a holding pattern. A genuine prospect is marked by specific follow-up questions, a named technical lead, a dated next step, and a briefing arranged on the prime's site. Glossy brochures and bold sales pitches do not land well with DE&S and prime engineering teams. Specific capability claims supported by test data travel further than adjectives.

The UK's civil aerospace industry works at a different pace. Airbus's UK wing relationships at Broughton and Filton are managed on multi-year qualification and supplier-development cycles; moving from design input to a purchase order on an A350 or A320 package is rarely a quick conversation. Rolls-Royce Civil Aerospace at Derby runs a 12- to 18-month qualification process before commercial dialogue begins in earnest, and approved-supplier status is held, not sold into. At Broughton, supply-chain locality matters more than at most defence sites: north-west England and the Wirral cluster are the practical catchment. Airbus differentiates between its tier-1 structural partners, managed as risk-sharing industrial relationships, and the deeper tier-2 base, run on a more conventional competitive-procurement footing.

New-supplier timelines run longer than most first-time entrants plan for. The UK defence community is small by international standards: continuity across Farnborough and DSEI matters, and repeat appearances and named relationships beat glossy marketing.

Trade Shows

The Farnborough International Airshow is the second largest show of its kind after the Paris Air Show, with over 1,500 exhibitors from 48 countries at the 2024 edition. It is a biennial week-long event demonstrating civilian and military aircraft to potential customers and investors, and announcing new developments and orders. For overseas suppliers this is the single most efficient UK networking event, combining civil and defence presence and attracting senior procurement delegations from across Europe (FIA 2026).

DSEI is a four-day international defence and security exhibition held biennially at the ExCeL Center in London. The 2025 edition attracted more than 35,000 attendees from over 100 countries with more than 1,000 exhibitors, including every major prime manufacturer (DSEI). DSEI is defence-focused and is particularly strong for land systems, naval, and C4ISR suppliers.

How Westworld helps

Westworld is based at Aztec West, Bristol, in the heart of the UK's aerospace and defence cluster: roughly ten minutes from Airbus Filton, Rolls-Royce Filton, GKN Aerospace and MOD Abbey Wood.

Our team has worked directly with UK OEMs, primes, their supply chains and their programme teams for three decades, on both the civil side (Airbus wing work at Broughton and Filton, Rolls-Royce Trent supply chains, GKN structures) and the defence side (BAE combat air and submarines, MBDA UK complex weapons, Leonardo Helicopters at Yeovil, Babcock naval).

We understand how approved-supplier lists work, how to sequence FSC, Cyber Essentials, NADCAP and qualification against the commercial cycle, and how to structure a UK industrial-participation offer.
