Compare places

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.	Cambridge semiconductor and processor IP cluster	Not recorded on the map.
Infrastructure	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.	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.
Capital	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.	Prime contractor supply chain finance and public programmes rather than venture capital.
Government programmes	No place-based designation recorded.	No place-based designation recorded.	Solent Freeport — Freeports
What exists	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.	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.
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.	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.	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.
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.	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.	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	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.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.
