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	Space and Earth observation capability, Cornwall Aerodrome and space capability, marine research and test facilities and naval infrastructure.	Harwell Science and Innovation Campus Diamond Light Source Satellite Applications Catapult National laboratory campus facilities, quantum fabrication and metrology capability, and clinical research infrastructure.	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.	University-linked funds and specialist deep tech investors, with London capital an hour away.	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.	A research-intensive university alongside the Harwell campus, one of the largest concentrations of national scientific infrastructure in Britain, spanning space, energy, health and physical sciences, with distinctive quantum, vaccine and space applications strength.	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.	Access. National facilities are heavily used by their own communities; companies without an existing university relationship find the route in unclear. Scale-up space and later-stage capital are also constrained.	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.	Opening national facility access to companies across Britain as shared ecosystem infrastructure, and pairing Oxford quantum and space capability with manufacturing clusters that could produce at volume.	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.	Oxford has infrastructure most countries cannot build. The proposed zone focuses on making that infrastructure accessible to companies that are not spin-outs of the university.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.
