Future Combat Systems: The company is investing in next-generation defense capabilities through its Anduril UK partnership, positioning itself for upcoming unmanned aerial vehicle contracts.

GKN Aerospace has established itself as the undisputed leader in aerospace additive manufacturing, with strategic investments totaling hundreds of millions across multiple continents.

Trollhättan, Sweden: In January 2024, GKN announced a £50 million investment (600 million SEK) to expand its Trollhättan facility. This investment created the world’s largest pre-production additive manufacturing cell for aerospace components.

The Swedish facility houses multiple large-format metal 3D printing systems capable of producing components up to 1.5 meters in diameter. The facility expansion added 5,000 square meters of manufacturing space dedicated to additive fabrication.

Newington, Connecticut: GKN expanded its Connecticut operations in September 2025 with a new production line specifically for Fan Case Mount Ring manufacturing. This strategic move brought critical capability closer to U.S. customers and created new high-skilled jobs.

The Newington facility received post-processing and finishing equipment to complement the primary additive manufacturing conducted in Sweden. This transatlantic production model optimizes both locations’ capabilities while maintaining quality standards.

Kongsberg, Norway: In December 2025, GKN signed a strategic agreement with Norwegian Catapult Manufacturing Technology to expand advanced additive manufacturing at its engines facility in Kongsberg.

Norwegian Catapult and The Industrial Growth Company (SIVA) co-invested NOK 12 million (approximately £1 million) alongside GKN’s investment. This partnership accelerates industrial adoption of additive manufacturing and builds a platform for sustainable manufacturing innovation in Norway.

Additive manufacturing provides several critical advantages for aerospace applications:

Material Efficiency: Traditional subtractive manufacturing often wastes 90% or more of expensive aerospace-grade metals. Additive manufacturing builds components layer by layer, using only the material required for the final part geometry.

Design Freedom: Engineers can create complex internal structures, cooling channels, and optimized geometries impossible to manufacture using conventional methods. This enables significant weight reduction while maintaining or improving structural performance.

Supply Chain Resilience: Additive manufacturing reduces dependence on complex supply chains and long-lead-time forgings or castings. Components can be produced closer to final assembly locations, reducing transportation costs and inventory requirements.

Rapid Prototyping: New designs can be tested and refined much faster than traditional manufacturing allows. This accelerates development timelines for new aircraft and engine programs.

The Fan Case Mount Ring exemplifies these advantages. This component would require multiple forgings, castings, and machining operations using traditional methods. GKN’s additive approach produces the part in a single build, reducing material waste by approximately 75% and cutting production time significantly.

Business Facilities magazine honored GKN Aerospace with the 2025 Aerospace Impact Award in January 2026, specifically recognizing the groundbreaking Newington expansion and the first-of-its-kind 3D-printed aircraft component achievement.

This recognition underscores GKN’s technological leadership and successful industrialization of additive manufacturing for safety-critical aerospace applications. The company has moved beyond prototyping to serial production of flight-critical components, a milestone few aerospace manufacturers have achieved.

GKN Aerospace announced a transformative partnership in December 2025 that positions the company at the forefront of autonomous defense systems.

GKN signed a strategic teaming agreement with Anduril Industries UK to accelerate development of advanced uncrewed aerial vehicles (UAV) and rotorcraft technologies for UK defense programmes.

The partnership targets two major UK government contracts:

Archer Aviation joins the collaboration, contributing eVTOL (electric vertical takeoff and landing) expertise.

This tri-party partnership combines GKN’s manufacturing excellence, Anduril’s autonomy and defense technology, and Archer’s advanced propulsion systems.

Under the collaboration, GKN Aerospace will lead structural design and integration work. The company brings world-class expertise in aerostructures, electrical wiring interconnection systems (EWIS), and aerospace engineering.

Much of the work will be delivered from GKN’s Cowes facility on the Isle of Wight, which recently received a £10 million investment. The facility features state-of-the-art cleanrooms, processing equipment, and training facilities ready to support growth in next-generation platforms.

If successful in winning the targeted contracts, the collaboration is expected to create more than 100 highly skilled roles at the Isle of Wight site over the next three years.

GKN currently employs almost 1,000 people at its Cowes facility, making it the largest private employer on the island. The potential expansion would represent a significant boost to the regional economy and advanced manufacturing capability.

Richard Quigley, Isle of Wight West Member of Parliament, attended the signing ceremony and emphasized the partnership’s importance for demonstrating that innovative, high-tech manufacturing and advanced defense capability development continues thriving in the UK.

This partnership represents GKN’s strategic pivot toward next-generation defense platforms. Traditional military aircraft programs often span decades, but the UAV and autonomous systems market is experiencing rapid growth and evolution.

The UK government has prioritized autonomous systems development as part of broader defense modernization efforts. Multiple contracts worth billions of pounds are expected to be awarded in 2026 and beyond.

GKN’s partnership with Anduril, a U.S.-based defense technology unicorn known for innovation and rapid development cycles, positions the company to compete effectively against traditional defense contractors. The collaboration combines established aerospace manufacturing expertise with cutting-edge autonomy technology.

GKN Aerospace operates within an intensely competitive global aerospace supply chain, facing competition from both established players and emerging manufacturers.

Spirit AeroSystems represents GKN’s most direct competitor in aerostructures. The U.S.-based company supplies fuselage sections, wing components, and other structural assemblies to Boeing, Airbus, and other aircraft manufacturers.

Boeing’s acquisition of Spirit’s commercial operations in 2024 altered competitive dynamics, potentially creating opportunities for GKN as other OEMs seek supply chain diversification.

Collins Aerospace (RTX Corporation) competes across multiple domains including engine components, nacelles, electrical systems, and landing gear. Collins benefits from its position within RTX, which also owns Pratt & Whitney.

This vertical integration provides Collins with preferential access to certain engine programs. However, GKN’s independent status makes it an attractive partner for OEMs seeking to avoid single-source dependencies.

Safran Aircraft Engines competes in engine systems while also serving as a key GKN customer through the LEAP engine program. This customer-competitor relationship is common in aerospace, where companies collaborate on some programs while competing on others.

Premium AEROTEC (now part of Airbus) formerly competed directly with GKN in aerostructures. Airbus’s acquisition of Premium AEROTEC may create opportunities as other aircraft manufacturers seek independent suppliers to balance their supply chains.

GKN Aerospace possesses several distinctive competitive advantages:

Technology Leadership: The company’s dominance in additive manufacturing for flight-critical components represents a significant technological moat. Competitors face years of development, testing, and certification to replicate GKN’s capabilities.

Global Manufacturing Footprint: With 32 facilities across 12 countries, GKN can serve customers locally while maintaining global scale. This geographic diversity also provides resilience against regional disruptions.

Diverse Customer Base: GKN supplies components to virtually every major aircraft and engine manufacturer. This diversification reduces dependence on any single customer or program.

Design Capabilities: GKN functions not just as a manufacturer but as a design partner on major programs. This early involvement creates barriers to entry for competitors and generates higher-margin work.

Scale Gap: Some competitors, particularly those within larger aerospace conglomerates, benefit from greater financial resources and vertical integration. Spirit AeroSystems, despite recent challenges, operates larger aerostructures facilities than GKN.

OEM Insourcing: Major aircraft manufacturers periodically insource work previously performed by suppliers. This trend accelerated as Boeing acquired Spirit’s operations.

New Entrants: Low-cost manufacturers in emerging markets increasingly compete for less-complex components. While these competitors lack capability for the most sophisticated systems, they pressure margins on simpler products.

Supply Chain Pressure: As a tier-one supplier, GKN faces continuous pressure from customers to reduce costs while simultaneously experiencing cost increases from its own suppliers and labor markets.

The global aerospace industry has grappled with significant supply chain disruptions since 2020, and GKN has not been immune to these challenges.

In August 2024, parent company Melrose Industries cut its 2025 revenue outlook to £3.8 billion from £4 billion previously, citing supply chain challenges.

These issues primarily stemmed from:

The aerospace industry’s rapid production ramp-up after the pandemic created bottlenecks throughout the supply chain. Aircraft manufacturers increased production targets faster than suppliers could scale capacity, creating mismatches between demand and supply.

GKN has implemented several strategies to address supply chain vulnerabilities:

Vertical Integration Through Additive Manufacturing: By producing critical components in-house using additive manufacturing, GKN reduces dependence on long-lead-time forgings and castings from external suppliers.

Supplier Development Programs: GKN works closely with critical suppliers to improve their processes, quality systems, and capacity. The company has increased technical support to sub-tier suppliers experiencing difficulties.

Inventory Buffers: While lean manufacturing principles traditionally minimize inventory, GKN has strategically increased safety stock for critical materials and components to buffer against supply disruptions.

Geographic Diversification: The company’s global manufacturing footprint allows production shifting when regional challenges emerge. Components can be sourced from alternative locations when primary suppliers face difficulties.

GKN Aerospace is assessing the impact of potential U.S. tariffs on its global supply chain. The company may take mitigation measures including boosting U.S.-based manufacturing capacity to reduce cross-border shipments.

This challenge reflects broader trade policy uncertainties affecting global aerospace manufacturers. GKN’s international footprint provides flexibility to adjust sourcing and production location, though such changes require significant time and investment.

GKN Aerospace has positioned itself as a leader in developing technologies for aviation’s zero-emissions future.

In July 2024, GKN launched H2FlyGHT, a £44 million project developing a 2-megawatt cryogenic hydrogen-electric propulsion system.

This collaborative initiative brings together industry partners and academic institutions to create next-generation propulsion technology. The 2 MW power output targets regional aircraft applications, representing a critical step toward decarbonizing commercial aviation.

Hydrogen propulsion systems face significant technical challenges including cryogenic fuel storage, fuel cell efficiency, thermal management, and integration with aircraft systems. The H2FlyGHT programme addresses these challenges through systematic development and demonstration.

GKN joined the HyFIVE consortium in March 2024, leading liquid hydrogen fuel system development for zero-emission aviation.

This consortium brings together aerospace manufacturers, fuel system specialists, and research organizations to develop infrastructure and systems required for liquid hydrogen aircraft operations. The programme focuses on fuel storage, distribution, refueling, and safety systems.

Liquid hydrogen presents unique challenges compared to conventional jet fuel, including extremely low storage temperatures (-253°C), different material compatibility requirements, and novel refueling procedures. The HyFIVE programme aims to establish standards and demonstrate practical solutions for these challenges.

The H2GEAR programme represents another UK-based collaborative project led by GKN Aerospace. The goal is developing a liquid hydrogen propulsion system for sub-regional aircraft that could eventually scale to larger aircraft.

GKN partners with Intelligent Energy on fuel cell technology and other specialists on system integration.

The aviation industry has committed to achieving net-zero carbon emissions by 2050. Hydrogen propulsion represents one of few viable pathways for medium and long-haul commercial aviation, where battery-electric propulsion faces insurmountable energy density limitations.

GKN’s early investment in hydrogen technologies positions the company as a preferred partner when aircraft manufacturers begin developing hydrogen-powered aircraft. First commercial hydrogen aircraft could enter service in the 2030s, with significant production volumes following in subsequent decades.

Companies establishing technical expertise and intellectual property now will capture disproportionate value as the industry transitions. GKN’s participation in multiple UK government-funded programmes also strengthens relationships with regulators and standards bodies shaping future requirements.

GKN Aerospace’s financial trajectory reflects both the broader aerospace recovery and the company’s strategic initiatives.

Parent company Melrose Industries reported GKN Aerospace’s performance as part of its consolidated results for calendar year 2024:

The operating margin expansion demonstrates GKN’s improving operational efficiency and favorable program mix. Higher-margin aftermarket and RRSP revenues grew faster than lower-margin OE sales.

For 2025, Melrose projects revenue of £3.55-3.70 billion, representing 2-7% growth over 2024. Adjusted operating profit is expected to reach £650-690 million, implying operating margins of 18-19%.

The more modest revenue growth reflects ongoing supply chain constraints and cautious production planning by aircraft manufacturers. However, profit margin expansion continues as GKN realizes benefits from previous investments and efficiency initiatives.

Five-Year Targets: Melrose announced ambitious targets in March 2025, projecting approximately £5 billion in revenue and £1.2 billion in adjusted operating profit by 2029. This implies:

These targets assume continued aerospace production growth, successful program execution, and margin improvement through operational excellence initiatives.

GKN’s business model generates strong cash flows once programs reach maturity. However, upfront investments in RRSP programs and new facility developments can consume significant cash in growth periods.

Free cash flow for 2024 was £52 million, down from £113 million in 2023. The reduction primarily reflected increased capital expenditures for additive manufacturing facilities and working capital requirements as production volumes increased.

Management expects free cash flow to improve significantly as major capital projects complete and production stabilizes. The company targets converting over 100% of operating profit to free cash flow in normalized years.

Beyond financial metrics, GKN creates value through several dimensions relevant to industry stakeholders:

Intellectual Property Development: The company’s investment in additive manufacturing, hydrogen propulsion, and advanced materials generates patents and proprietary knowledge with long-term competitive value.

Workforce Development: GKN’s training programs and apprenticeships develop specialized aerospace skills critical to industry competitiveness. The company’s 16,000 employees represent significant human capital.

Supply Chain Strengthening: GKN’s supplier development initiatives and technology transfer programs strengthen the broader aerospace supply base, benefiting the entire industry ecosystem.

GKN Aerospace faces multiple risks that could impact performance over the next several years.

Bull Case Scenario: Aerospace production rates exceed current expectations as airlines continue fleet renewal and expansion. GKN successfully captures new programs on next-generation aircraft, hydrogen propulsion technologies reach commercial viability faster than expected, and additive manufacturing expands to additional components. Revenue could reach £6 billion+ by 2029 with operating margins exceeding 25%.

Base Case Scenario: Production rates increase steadily but conservatively, meeting current manufacturer guidance. GKN maintains current market share across major programs, hydrogen technologies develop on expected timelines, and operational improvements drive margins to 24% range. Revenue reaches approximately £5 billion by 2029 as currently guided.

Bear Case Scenario: Economic headwinds slow aerospace recovery, production rate increases disappoint, and intense price competition pressures margins. GKN loses share on one or more major next-generation programs, capital investments in new technologies deliver below-expected returns. Revenue growth stalls below £4.5 billion by 2029 with margins remaining below 20%.

GKN Aerospace enters 2026 with considerable momentum across multiple dimensions.

The company’s aggressive investment in additive manufacturing has created a substantial technological lead that competitors will struggle to close. The industrialization of 3D-printed flight-critical components represents a genuine paradigm shift in aerospace manufacturing, with implications extending far beyond current applications.

As certification authorities and OEMs gain confidence in these processes, the range of components suitable for additive manufacturing will expand dramatically.

The Anduril partnership demonstrates strategic flexibility and willingness to embrace non-traditional collaborations. Defense technology is evolving rapidly, and established contractors face challenges from innovative entrants.

GKN’s manufacturing expertise combined with Anduril’s autonomy capabilities and Archer’s eVTOL technology creates a formidable team positioned to capture significant value from the modernization of military aviation.

Supply chain challenges have moderated but not disappeared. The aerospace industry’s ambitions for production growth continue outpacing supply base capability in numerous areas.

Companies that successfully navigate these constraints while maintaining quality will gain market share. GKN’s investments in vertical integration, supplier development, and geographic diversity position it relatively well, though vigilance remains essential.

The hydrogen propulsion investments appear prescient given aviation’s decarbonization imperatives.

While commercial hydrogen aircraft remain years away, companies establishing expertise and intellectual property now will dominate this market when it materializes. GKN’s participation in multiple UK-funded programmes provides both technical knowledge and regulatory relationships that will prove valuable.

Financial performance has been solid, with revenue growth and margin expansion both tracking positively. The five-year targets appear achievable if aerospace production continues recovering and operational improvements materialize as planned. However, these targets leave little room for major setbacks or market disruptions.

The key question for stakeholders is whether GKN can sustain its technology leadership and translate that advantage into durable competitive moats and superior financial returns.

History suggests aerospace suppliers face continuous pressure from both customers demanding cost reductions and competitors offering alternatives.

GKN’s success will ultimately depend on execution across complex global operations while simultaneously investing in next-generation technologies.
