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	Not recorded on the map.	Bristol semiconductor and processor design cluster	Not recorded on the map.
Infrastructure	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.	Energy Systems Catapult UK Battery Industrialisation Centre Automotive research centres, battery and vehicle test facilities and major logistics assets.
Capital	Prime contractor supply chain finance and public programmes rather than venture capital.	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.	Corporate and supply chain finance dominate; venture capital is thin relative to industrial output.
Government programmes	Solent Freeport — Freeports	No place-based designation recorded.	West Midlands Investment Zone — Investment Zones
What exists	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.	The largest manufacturing base in the UK by employment, automotive and electrification engineering, rail and mobility research, and a young, large working-age population.
What's missing · UKIZ interpretation	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.	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.
What could connect · UKIZ interpretation	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.	Midlands manufacturing paired with battery and power electronics research, North East battery production and Coventry testing capability as a single electrification value chain.
UKIZ relevance	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	Bristol's design and robotics capability has historically been acquired rather than scaled. The proposed zone concentrates on the capital and customer connections that let companies stay independent.	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.
