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. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Not recorded on the map. Plant and food research institutes, genomics facilities and offshore energy operations bases.
Capital	Prime contractor supply chain finance and public programmes rather than venture capital.	Public and corporate capital dominate; venture funding is limited by capital intensity.	Research council and charitable funding dominate; venture capital is scarce.
Government programmes	Solent Freeport — Freeports	Wales Investment Zone designations — Investment Zones	Freeport East — Freeports
What exists	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.	Plant, food and genomics research of international standing, offshore energy operations and maintenance, and a significant agricultural production base on the doorstep.
What's missing · UKIZ interpretation	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	Commercial translation of agri-food science, and connection between offshore energy operations and the research base inland.
What could connect · UKIZ interpretation	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	Agri-food and genomics research connected to national food manufacturing and to engineering biology capacity, and offshore operations connected to the Humber and North East energy supply chain.
UKIZ relevance	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	Food security and biotechnology intersect here more clearly than anywhere else in Britain, and connect to the proposed Oxford–Cambridge mission.
