Two or three clusters, read side by side across sectors, research, companies, capital, infrastructure, government designations and UKIZ relevance. There is no score and no ranking: British clusters are different from one another, not better or worse than one another.

Companies	South Wales compound semiconductor cluster	Not recorded on the map.	Northern Ireland aerospace and composites cluster
Infrastructure	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	Not recorded on the map. Cyber security innovation centre, composites and aerostructures manufacturing and agri-food research facilities.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	Prime contractor supply chain finance and public programmes rather than venture capital.	A small local venture base supported by public co-investment; growth capital typically comes from Dublin, London or the US.
Government programmes	Wales Investment Zone designations — Investment Zones	Solent Freeport — Freeports	No place-based designation recorded.
What exists	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	Cyber security research and commercialisation of international standing, aerospace and composites manufacturing, agri-food research and a fast-growing software sector.
What's missing · UKIZ interpretation	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Scale-up capital and market access. Companies reach a ceiling and are acquired, and dual-market access advantages are under-exploited commercially.
What could connect · UKIZ interpretation	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	Belfast cyber capability connected to UK defence and financial services demand, and composites manufacturing connected to Bristol and Midlands aerospace supply chains.
UKIZ relevance	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	Northern Ireland's position between two markets is a commercial asset that is under-used. The proposed Northern Ireland mission treats it as the organising advantage.
