Compare places

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	Bristol semiconductor and processor design cluster	Not recorded on the map.	Not recorded on the map.
Infrastructure	National Composites Centre Quantum and robotics laboratories, national composites facilities and aerospace test capability.	Not recorded on the map. Naval and maritime engineering facilities, photonics research centres and port infrastructure.	Advanced Manufacturing Research Centre Nuclear AMRC High Value Manufacturing Catapult centres, nuclear manufacturing facilities and industrial research factories.
Capital	An established angel and seed base with strong deep tech interest; growth rounds usually come from London or the US.	Prime contractor supply chain finance and public programmes rather than venture capital.	Public co-investment, corporate partnership and asset finance rather than venture capital.
Government programmes	No place-based designation recorded.	Solent Freeport — Freeports	No place-based designation recorded.
What exists	Semiconductor and processor design, quantum engineering, robotics and autonomous systems, aerospace and composites, and a creative and screen economy of national significance.	Maritime, naval and defence engineering, marine autonomy, photonics research and a major port and logistics complex.	One of the strongest applied manufacturing research bases in Europe, covering machining, materials, nuclear manufacturing and factory-scale process development, working directly with industrial customers.
What's missing · UKIZ interpretation	Fabrication and volume production capacity to match the design strength, and hardware-friendly capital. Companies scale by moving production abroad.	Routes for smaller innovators into defence and maritime procurement, and a civil market for capability developed for defence customers.	Domestic demand. World-class process capability is often demonstrated for overseas primes, and local SMEs lack the capital to adopt what is proven a mile away.
What could connect · UKIZ interpretation	Bristol design capability connected to South Wales compound semiconductor fabrication and to composites and aerospace manufacturing — a western technology corridor with a complete chain.	Marine autonomy and photonics connected to Plymouth marine capability, Bristol robotics and offshore energy operations — the same technologies serving defence, energy and shipping.	Applied manufacturing research connected to domestic customers — energy, defence, mobility and medical technology — with procurement used as the connector rather than grants.
UKIZ relevance	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.	Marine autonomy is where defence, robotics and clean energy meet. The proposed Cornwall & Devon marine mission connects to this capability directly.	The research is world class; the domestic customer base for what it produces is thinner than it should be. The proposed Midlands and Teesside & Humber missions both depend on this capability.
