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	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.	National Manufacturing Institute Scotland Satellite manufacturing capacity, nanofabrication cleanrooms and national manufacturing research facilities.
Capital	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.	Public co-investment and specialist funds; hardware scale-up capital is scarce.
Government programmes	No place-based designation recorded.	Solent Freeport — Freeports	No place-based designation recorded.
What exists	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.	More small satellites built here than anywhere else in Europe, quantum imaging and nanofabrication research, and a large applied engineering, manufacturing and energy research base.
What's missing · UKIZ interpretation	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.	Downstream value. Satellites are manufactured here while much of the data and applications value is captured elsewhere. Scale-up finance for hardware is limited.
What could connect · UKIZ interpretation	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.	Glasgow manufacture connected to Cornwall launch and Earth observation, Harwell space applications and domestic data customers — one national space chain instead of four regional ones.
UKIZ relevance	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.	Manufacture, launch and data are three different geographies in Britain. The proposed Scotland mission connects them deliberately.
