UK's aerospace and manufacturing sectors bet on ASICs to drive decarbonisation and supply-chain resilience

Aerospace and advanced manufacturing in the UK are converging on a single technical linchpin: microelectronics. In a sector where every gram saved and every millisecond of latency reduced translates directly into lower fuel burn, higher reliability and clearer commercial advantage, application-specific integrated circuits (ASICs) are emerging as a pragmatic route to the performance and efficiency gains government strategy documents and industry leaders say the country must achieve.

According to Ross Turnbull, Director of Business Development at Swindon Silicon, ASICs offer a level of functional consolidation and optimisation that general‑purpose silicon cannot match. His analysis, published in Electronics World, argues ASICs can combine analogue and digital signal conditioning, high‑resolution data conversion, power management and embedded security on a single die, reducing system complexity, electromagnetic interference and thermal loading while improving signal integrity under the vibration and temperature extremes typical of avionics. The result, he says, is lighter, more reliable avionics and industrial control systems that support the UK’s ambitions for sustainable, technologically advanced aviation.

Those ambitions are explicit in government planning. The UK’s Modern Industrial Strategy for Advanced Manufacturing is a ten‑year framework designed to increase business investment and accelerate the deployment of the industries of the future, including aerospace and smart factories. The strategy stresses advanced technical development and greater digital adoption as central to raising productivity and supporting decarbonisation across manufacturing and transport. According to the Department for Business and Trade, the plan seeks to make it quicker and easier for firms to invest by providing certainty for long‑term decisions and targeting sectors from clean energy to defence and digital technologies.

Semiconductors are singled out in public policy as foundational to that vision. The UK government has set out a long‑term semiconductor strategy, committing up to £1 billion of public investment over the coming decade to bolster design capability, research and development and compound semiconductor activity, and to attract inward collaboration. Industry data cited in the government announcement aims to double annual business investment in the sector from around £21 billion to £39 billion by 2035. Innovate UK has separately funded targeted projects to strengthen manufacturing processes and supply‑chain resilience, with a recent £11.5 million package supporting 16 projects to scale UK semiconductor manufacturing and link designers with manufacturers.

Taken together, these policy moves create a clear rationale for ASICs in both aerospace and smart factories. In aircraft, bespoke chips can process telemetry and sensor fusion on‑board in real time, enabling predictive maintenance, enhanced situational awareness and the computational headroom required for advanced assisted or autonomous flight modes. In factories, ASICs embedded in IIoT sensors, robotics controllers and automated guided vehicles reduce data transmission overheads by pre‑filtering and interpreting data at source, lowering energy consumption and enabling deterministic control loops for safety‑critical operations.

There are also strategic supply‑chain considerations. Turnbull highlights that ASICs reduce reliance on proliferating off‑the‑shelf parts that may become obsolete or subject to constrained supply, thereby lowering redesign risk and supporting long system life‑cycles demanded by aerospace and industrial customers. This fits with the government’s stated aim of strengthening domestic semiconductor capability so that the UK can better control access to critical components and sustain high‑value manufacturing.

Nonetheless, the case for expanded ASIC adoption sits against a competitive international landscape and the practical realities of chip design and production. The government strategy itself acknowledges the long horizon required to scale semiconductor ecosystems and the need for sustained public‑private commitment: the announced £1 billion is intended to catalyse investment, improve access to infrastructure and encourage international cooperation, but will require follow‑through from industry to meet ambitious investment targets. Industry initiatives, such as funding to promote secure chip blueprints and accelerator schemes for hardware startups, are designed to accelerate that translation from research to product.

For industrial decarbonisation professionals, the implication is clear: hardware choices matter. ASICs offer pathways to lower energy intensity and improved lifecycle performance that software or system‑level optimisation alone cannot deliver. Whether through weight savings in aircraft that reduce CO2 per seat‑kilometre, or through edge processing in factories that shrinks energy use and extends asset life, ASICs are an enabling technology for the decarbonisation and resilience objectives set out in national policy.

Adoption will not be automatic. Design costs, time to market and access to advanced foundry capacity remain barriers, and the UK’s competitiveness will depend on how effectively public funds, research institutions and private firms translate strategic intent into accessible design flows, test and prototyping facilities, and supply‑chain partnerships. According to UK government releases, existing measures, R&D funding, regional cluster investment and targeted accelerator support, are intended to address those gaps; their success will determine whether ASICs become a broadly used instrument of industrial transformation or remain niche solutions for high‑value systems.

In short, ASICs are a practical technical lever that aligns with the UK’s industrial strategy: they can materially improve system efficiency, reliability and longevity in aerospace and smart manufacturing, while helping manage supply‑chain risk. Realising their potential will require continued public investment, focused support for design‑to‑manufacture pathways and industry partners prepared to shoulder the upfront costs of bespoke silicon in return for lifecycle gains that pay out across carbon, performance and total cost of ownership.
