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	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	MediaCity Advanced manufacturing Catapult capability, North West National materials and graphene facilities, teaching hospitals and clinical research capability, and a major broadcast production estate.	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	A growing regional investor base and northern funds, with growth rounds usually led from London.	Prime contractor supply chain finance and public programmes rather than venture capital.
Government programmes	Wales Investment Zone designations — Investment Zones	No place-based designation recorded.	Solent Freeport — Freeports
What exists	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.	Advanced materials research including graphene and 2D materials, a large health innovation base built on hospitals and universities, a substantial digital and cyber economy, and the biggest broadcast and creative cluster outside London.	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.
What's missing · UKIZ interpretation	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	The step from materials discovery to volume production, and a growth capital base proportionate to the research output. Health data at population scale is under-used by industry.	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.
What could connect · UKIZ interpretation	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	Materials research connected to Sheffield and Midlands manufacturing, and health innovation connected to Leeds health data capability — a corridor rather than three separate cities.	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	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	Manchester has scale in four different economies that rarely commission from each other. The proposed zone concentrates on connecting health, materials, digital and creative capability around shared missions.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.
