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.

Infrastructure	Not recorded on the map. Health data infrastructure, teaching hospitals and university research facilities.	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.
Capital	Financial services depth locally, but early-stage health technology capital remains limited.	Public and corporate capital dominate; venture funding is limited by capital intensity.	Prime contractor supply chain finance and public programmes rather than venture capital.
Government programmes	No place-based designation recorded.	Wales Investment Zone designations — Investment Zones	Solent Freeport — Freeports
What exists	National health data organisations, medical technology, a large financial and professional services base and a research university with data and materials strength.	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.
What's missing · UKIZ interpretation	A clear route for companies to work with health data at scale, and clinical adoption pathways that move faster than pilot projects.	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.
What could connect · UKIZ interpretation	Leeds health data capability connected to Manchester clinical research and to medical technology manufacturing, giving companies discovery, evidence and production in one region.	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.
UKIZ relevance	Health data at population scale is a national asset. The proposed Manchester mission and Leeds capability are complementary rather than competing.	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.
