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.

Energy Systems Catapult UK Battery Industrialisation Centre Automotive research centres, battery and vehicle test facilities and major logistics assets.	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.	Corporate and supply chain finance dominate; venture capital is thin relative to industrial output.	Prime contractor supply chain finance and public programmes rather than venture capital.

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.	The largest manufacturing base in the UK by employment, automotive and electrification engineering, rail and mobility research, and a young, large working-age population.	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.	Ownership of the value in electrified vehicles: battery, power electronics and software increasingly sit outside the region and outside the UK. Innovation-active SME supply chains are under-capitalised.	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.	Midlands manufacturing paired with battery and power electronics research, North East battery production and Coventry testing capability as a single electrification value chain.	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.	The region's transition depends on owning the new value in a vehicle rather than assembling someone else's. The proposed Midlands zone focuses on batteries, power electronics and software.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.
