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	South Wales compound semiconductor cluster	Not recorded on the map.	Glasgow small satellite manufacturing cluster
Infrastructure	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Space and Earth observation capability, Cornwall Aerodrome and space capability, marine research and test facilities and naval infrastructure.	National Manufacturing Institute Scotland Satellite manufacturing capacity, nanofabrication cleanrooms and national manufacturing research facilities.
Capital	Public and corporate capital dominate; venture funding is limited by capital intensity.	Public programmes and a small local investor base; almost all growth capital is external.	Public co-investment and specialist funds; hardware scale-up capital is scarce.
Government programmes	Wales Investment Zone designations — Investment Zones	No place-based designation recorded.	No place-based designation recorded.
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.	Space launch and Earth observation capability, marine autonomy and ocean research, and a distinctive combination of coastline, test space and specialist facilities.	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	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	Company density and connectivity. Excellent facilities sit a long way from capital, customers and complementary suppliers, and skilled people are hard to retain.	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	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	Launch and Earth observation connected to Glasgow satellite manufacture and Harwell applications, and marine autonomy connected to Solent defence and offshore energy demand.	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	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	The proposed Cornwall & Devon mission treats the sea and the satellite economy as one system rather than two separate sectors.	Manufacture, launch and data are three different geographies in Britain. The proposed Scotland mission connects them deliberately.
