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	Not recorded on the map.	Bristol semiconductor and processor design cluster	Cambridge semiconductor and processor IP cluster
Infrastructure	Space and Earth observation capability, Cornwall Aerodrome and space capability, marine research and test facilities and naval infrastructure.	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.	Babraham Research Campus Cambridge Science Park University and institute laboratories, genomics and biomedical campus facilities, and semiconductor design capability.
Capital	Public programmes and a small local investor base; almost all growth capital is external.	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.	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	No place-based designation recorded.	No place-based designation recorded.	No place-based designation recorded.
What exists	Space launch and Earth observation capability, marine autonomy and ocean research, and a distinctive combination of coastline, test space and specialist facilities.	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.	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	Company density and connectivity. Excellent facilities sit a long way from capital, customers and complementary suppliers, and skilled people are hard to retain.	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.	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	Launch and Earth observation connected to Glasgow satellite manufacture and Harwell applications, and marine autonomy connected to Solent defence and offshore energy demand.	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.	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	The proposed Cornwall & Devon mission treats the sea and the satellite economy as one system rather than two separate sectors.	Bristol's design and robotics capability has historically been acquired rather than scaled. The proposed zone concentrates on the capital and customer connections that let companies stay independent.	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.
