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.	Cambridge semiconductor and processor IP cluster
Infrastructure	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Space and Earth observation capability, Cornwall Aerodrome and space capability, marine research and test facilities and naval infrastructure.	Babraham Research Campus Cambridge Science Park University and institute laboratories, genomics and biomedical campus facilities, and semiconductor design capability.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	Public programmes and a small local investor base; almost all growth capital is external.	Specialist deep tech and life science funds, university-linked funds, and corporate partners; strong at seed, thinner at growth stage relative to demand.
Government programmes	Wales Investment Zone designations — Investment Zones	No place-based designation recorded.	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.	Space launch and Earth observation capability, marine autonomy and ocean research, and a distinctive combination of coastline, test space and specialist facilities.	Extreme research density for its size: life sciences and genomics, semiconductor and processor IP, engineering biology and AI, with a mature spin-out culture and specialist investors who understand long timelines.
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.	Company density and connectivity. Excellent facilities sit a long way from capital, customers and complementary suppliers, and skilled people are hard to retain.	Ownership retention. Discovery and early company formation work; the Series B onward stage frequently transfers ownership overseas. Laboratory and scale-up space, power and housing also constrain growth.
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.	Launch and Earth observation connected to Glasgow satellite manufacture and Harwell applications, and marine autonomy connected to Solent defence and offshore energy demand.	Cambridge discovery connected to UK manufacturing and biomanufacturing capacity, and to later-stage domestic capital, so that value created here is realised here rather than acquired out of the country.
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.	The proposed Cornwall & Devon mission treats the sea and the satellite economy as one system rather than two separate sectors.	Cambridge produces intellectual property at a rate few places match, and loses ownership of too much of it at Series B. The proposed Oxford–Cambridge zone concentrates on commercialisation and retention rather than on more discovery.
