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	Glasgow small satellite manufacturing cluster	South Wales compound semiconductor cluster	Not recorded on the map.
Infrastructure	National Manufacturing Institute Scotland Satellite manufacturing capacity, nanofabrication cleanrooms and national manufacturing research facilities.	Not recorded on the map. Compound semiconductor fabrication and research facilities, materials and coatings research, production studios.	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.
Capital	Public co-investment and specialist funds; hardware scale-up capital is scarce.	Public and corporate capital dominate; venture funding is limited by capital intensity.	Prime contractor supply chain finance and public programmes rather than venture capital.
Government programmes	No place-based designation recorded.	Wales Investment Zone designations — Investment Zones	Solent Freeport — Freeports
What exists	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.	The UK's compound semiconductor cluster, combining research, fabrication and supply chain, alongside steel and coatings materials research, and a significant screen production economy.	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.
What's missing · UKIZ interpretation	Downstream value. Satellites are manufactured here while much of the data and applications value is captured elsewhere. Scale-up finance for hardware is limited.	Design demand. Fabrication capability needs a pipeline of UK customers designing products that use it, and capital patient enough for semiconductor timelines.	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.
What could connect · UKIZ interpretation	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.	South Wales fabrication connected to Bristol and Cambridge chip design and to defence, automotive and energy customers who currently source overseas.	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	Manufacture, launch and data are three different geographies in Britain. The proposed Scotland mission connects them deliberately.	Compound semiconductors are a genuine national specialism with a fragile ownership base. The proposed Wales mission focuses on keeping the value chain here.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.
