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.

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.	One of the strongest applied manufacturing research bases in Europe, covering machining, materials, nuclear manufacturing and factory-scale process development, working directly with industrial customers.
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.	Domestic demand. World-class process capability is often demonstrated for overseas primes, and local SMEs lack the capital to adopt what is proven a mile away.
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.	Applied manufacturing research connected to domestic customers — energy, defence, mobility and medical technology — with procurement used as the connector rather than grants.
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.	The research is world class; the domestic customer base for what it produces is thinner than it should be. The proposed Midlands and Teesside & Humber missions both depend on this capability.
